The control system takes its input from a human operator and translates this command into the motion of actuators, which move the mechanical structure. The high performance and highly powerful, Pneumatic machine vice together with the capacity for high volumes are suited for Holding Heavy Objects.\r\n\r\n\u00a0See Also:AUTOMATIC PNEUMATIC VICE AND JACK\r\n\r\n\r\n\r\nFABRICATION HIGH PRESSURE PNEUMATIC MACHINE VICE\r\n\r\n\r\n\r\nOne form of inefficiency in current systems is due to the link between the flows of the two ports of the cylinder. This is because most valves use a single spool to control the flow in both ports. Because of this link, it is impossible to set the pressure levels in the two sides of the cylinder independently.\r\nTherefore, the outlet side will develop a back-pressure, which acts in opposition to the direction of travel, which increases the pressure required on the inlet side to maintain motion. Since the force generated by the actuator is proportional to the pressure difference between the two sides, the actual pressures in the cylinder don't affect the action of the cylinder.\r\nComponent required:\r\n\r\n \t\u00a0Pneumatic Cylinder\r\n \tAir Control\/ Flow Control valve\r\n \tBack Plate or supporting plate\r\n\r\nGenerally, Pneumatic cylinder operations are based on Pneumatic pump operation. Air is pumping to the Pneumatic cylinder by using Pneumatic pump system. It\u2019s the manual operation.\r\nApplication:\r\n\r\nCan be used where Mass Production is more.\r\n\r\n\r\n\r\nMore Resources \/articles\r\n\r\n\r\nPneumatic or Air operated projects\r\nHydraulic and Pneumatic Projects List - Abstract , Report Download\r\nNew Mechanical Projects 2020 ( All Projects Post Index List )\r\n\r\n\r\n\r\n&nbsp;","headline":"FABRICATION HIGH PRESSURE PNEUMATIC MACHINE VICE","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2016-03-03","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2016\/03\/FABRICATIONHIGHPRESSUREPNEUMATICMACHINEVICE-300x142.jpg","height":142,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/design-and-fabrication-of-pipe-inspection-robo/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2016/03/pipeinspectionrobotmechancialproject-min-300x193.jpg')"></div><span class="sr-only">link to Design and fabrication of pipe inspection robot Report Free Download</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/design-and-fabrication-of-pipe-inspection-robo/">Design and fabrication of pipe inspection robot Report Free Download</a></p></header><div class="excerpt"><p>Design and fabrication of pipe inspection robot Report Free Download  ABSTRACT  A pipe inspection robot is device that is inserted into pipes to check for obstruction or damage.

These robots are traditionally manufactured offshore, are extremely expensive, and are often not adequately supported in the event or malfunction. This had resulted in associated environmental services limited. A Newzealand utilize of this equipment, facing significant periods of down time as they wait for their robots to be the repaired. Recently, they were informing that several robots were no longer supported.\r\nThis project was conceived to redesign the electronics control systems one of these PIR, utilizing the existing mechanical platform. Requirements for the robot were that it must operate reliably in confined, dark and wet environments and provides a human wears with a digital video feed of the internal status of the pipes.\r\nThere robot should as much as possible incorporate off the shaft components, cheap, and potentially onsite repair. This project details the redesign and constructions of such robots. It employees there electronic boards integrated with mechanical components and provides video feedback via custom graphical interface although at the prototypes state the electronics has been successful with cost of less than a length of the original robot purchase prize.\r\n\r\n\r\nPipe Defects Which need to be Inspected:\r\n\r\n\r\n\r\n \tBuckle: regular buckle and sharp buckle\r\n \tOvality\r\n \tWrinkle\r\n \tKnob\r\n \tRolling imperfection or angularity\r\n \tTube expansion\r\n \tJoint imperfection: edge displacement and angle error\r\n\r\nDesign criteria For Pipe inspection Robot :\r\n\r\nDesign of the inspection robot depends on two main critical factors: size and shape of the pipeline.

Other arrangements are sometimes found on different types of vehicles, for example, a tiller or rear\u2013wheel steering. Tracked vehicles such as tanks usually employ differential steering \u2014 that is, the tracks are made to move at different speeds or even in opposite directions to bring about a change of course.\u00a0\r\n\r\nFour-wheel steering\r\n\r\nFour-wheel steering (or all wheel steering) is a system employed by some vehicles to improve steering response, increase vehicle stability while maneuvering at high speed, or to decrease turning radius at low speed. In most active four-wheel steering systems, the rear wheels are steered by a computer and actuators. The rear wheels generally cannot turn as far as the front wheels. Some systems, including Delphi's Quadrasteer and the system in Honda's Prelude line, allow for the rear wheels to be steered in the opposite direction as the front wheels during low speeds. This allows the vehicle\r\nto turn in a significantly smaller radius \u2014 sometimes critical for large trucks or vehicles with trailers. An electronic four-wheel steer system is an option available on the JCB Fastrac.\u00a0\r\n\r\n\r\n\r\nrack and pinion steering system\r\n\r\nMany modern vehicles offer a form of passive rear steering to counteract normal vehicle tendencies. For example, Subaru used a passive steering system to correct for the rear wheel's tendency to toe-out. On many vehicles, when cornering, the rear wheels tend to steer slightly to the outside of a turn, which can reduce stability. The passive steering system uses the lateral forces generated in a turn (through suspension geometry) and the bushings to correct this tendency and steer the wheels slightly to the inside of the corner. This improves the stability of the car, through the turn. This effect is called compliance understeer and it, or its opposite, is present on all suspensions. Typical methods of achieving compliance understeer are to use a Watt's Link on a live rear axle, or the use of toe control bushings on a twist beam suspension. On an independent rear suspension it is normally achieved by changing the rates of the rubber bushings in the suspension. Some suspensions will always have compliance oversteer due to geometry, such as Hotchkiss live axles or a semi trailing arm IRS.\r\n\r\nDescription:\r\n\r\nThis invention relates to a car headlight and more particularly, to a movable car headlight device which, when turning the car, illuminates the area into which the car is turning.\r\n\r\n\r\n\r\nFront Wheel Steering System\r\n\r\n\r\nConventional headlights and auxiliary lights are generally fixed at a certain angle to the front of a car body for lighting up the area in front of the car. Therefore, upon turning the steering wheel to change the direction of travel of the car, the front-wheel forms an angle corresponding to the angle at which the steering wheel was turned in relation to the direction of travel of the car. Thus, the car body moves in a direction which is not being illuminated by the headlights and therefore poses a danger because it is turned into a dark area.\r\n\r\nIt is therefore an object of the present invention to provide a novel headlight device for cars, which is designed so that when turning the car it automatically directs a light in the direction in which the car is turned. More specifically, the movable car headlight device of the present invention comprises a perpendicular main axis fixed to a bracket mounted on an appropriate part of the car body; a receiving table through which the main axis passes; a rotating body with balance weights on either side attached to the main axis the body rotatable resting on the receiving table; and a casing with a lamp at its rear part rotatable supported at the upper end of the main axis. The casing is connected to\u00a0 the rotating body so as to allow the rotating body to rise or fall independently and co-rotates with the casing.\r\n\r\nThe receiving table and the rotating body are adapted to contact each other in the form of a V-shaped wedge so that the rotating body is allowed to ride up from the contact surface as it is rotated due to centrifugal force exerted by the balance weights caused by the turning of the car, whereby the casing having a lamp is rotated and the rotating body is given a restoring force due to potential energy accumulated by riding up the V shaped surface of the receiving table.\r\nDownload:\r\n1) \u00a0Front Wheel Steering System with Movable Headlights Report Download\r\n2)\u00a0Design and Manufacture of Movable Headlight .\u00a0( Reference : www.ijiere.com)\r\n\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\n\r\n\r\nProject Sample report , Final report Download\r\nAutomobile Engineering Projects List - Abstract , Report\r\nAutomobile Engineering Parts and System Notes , Article\r\nNew Mechanical Projects 2020 ( All Projects Post Index List )\r\n\r\n\r\n\r\n&nbsp;","headline":"Front Wheel Steering System with Movable Headlights Report Download","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2016-03-03","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2016\/03\/steeringsystem-300x167.jpg","height":167,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/crop-harvester-in-agricultural-approac/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2016/03/CROPHARVESTINGMACHINEMechanicalagriculturalProject-300x152.jpg')"></div><span class="sr-only">link to CROP HARVESTER IN AGRICULTURAL APPROACH PDF Report Download</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/crop-harvester-in-agricultural-approac/">CROP HARVESTER IN AGRICULTURAL APPROACH PDF Report Download</a></p></header><div class="excerpt"><p>CROP HARVESTER IN AGRICULTURAL APPROACH

In India harvesting is generally done manually. Thus our intention is to provide farmer a \u201cCROP HARVESTER IN AGRICULTURAL APPROACH\u201d. This machine consists of simple mechanism make to run by an engine which will be economical to farmer and will take less time for harvesting operation.\r\nCrop harvesting is a process of cutting the crops closed to the ground or pulling the plants when they are ripped out. It include cutting the stems of coral crops like tuar, Jawar, Bajra, Maize etc. closed to the ground. in our country it is generally done by sharp sickle. On the basis of this large number of crop harvester are in use at today\u2019s date, which are available at different shape and size and on different power supply. Some of them are pneumatic crop harvester, hydraulic crops harvester and crop harvester running on tractor engine. Since they are costlier keeping in to consideration the\r\neconomic ability of our farmer it is required that is should be simple and should fulfill the same intention which are achieved by \u201cCROP HARVESTER IN AGRICULTURAL APPROACH\u201d. This machine is made to run by a single cylinder four stroke petrol engine of 197cc and having a speed of nearly 3600 rpm.\u00a0\r\n\r\nComponents Required:\r\n1. Engine -\r\n\u00a0It is the model of MK20HSPP of the mode hand pump. It is the type of 4 stroke air cooled engine net power is 3600 rpm (3HP).\u00a0\r\n\r\n2. HSS Metal strip\r\n3. MS Angle plate\u00a0\r\n4. MS Plate\r\n5. MS Rod (Bar)\u00a0\r\n6. GI pipe\u00a0\r\n7. Sheet Metal\u00a0\r\n8. Pedestal Bearing\u00a0\r\n9. CI. Pulley\u00a0\r\n10. Aluminum Pulley\u00a0\r\n11. V-Belt\u00a0\r\n12. Wood Wheel\u00a0\r\n13. Rubber grip of wheel\r\n14. Nut &amp; Bolt\u00a0\r\n15. Spring Washer\u00a0\r\n16. Hand Grip\u00a0\r\n17. Cable Wire\r\n18. Colour\u00a0\r\n\r\nWORKING:\r\n\r\n\u00a0Firstly the MK 20 3 HP single cylinder four stroke petrol engine having a speed of 3600 rpm is started by manually. The engine shaft which will get the power from engine. Then fixed a small cast iron driving pulley on these engine shafts. At this stage the speed of engine is 3600 rpm, but we required a speed of 900rpm for the operation of harvesting . For these purpose we use pulley and v belt drive on intermediate shaft for reducing the speed. Then we fixed 3 (A section) aluminum pulley\r\nand v belt on intermediate shaft. From these engine shafts power will be transmitted to the intermediate shaft with the help of pulley and v-belt drive.\r\n\r\n\r\n\r\nCrop Harvester Agricultural Project\r\n\r\n\r\n\u00a0The motion of power transmission from engine shaft to intermediate shaft is horizontal. And at this stage speed of intermediate shaft become 1800 rpm. And again for the purpose of harvesting operation we use two cutter shaft. At top end of these cutter shafts we fixed a 127mm aluminum driven pulley and at lower end of shaft cutter is fixed, similarly for other cutter shaft. The 2 driving pulley which is mounted on intermediate shaft will transmit the Power to the cutter shaft and at this stage we got the required speed of 900 rpm. By this ultimately a power will be transmitted to the both\r\ncutter and it\u2019s start to rotating whose half portion will be outside the length of casing. This half portion of cutter will comes in a contact with crops and perform harvesting operation without shattering of grain. These cutter revolve 15 times per second.\r\n\r\nADVANTAGES\u00a0\r\n\r\n1. Reduce the human effort:-crop harvester mostly designs for reduce the human efforts in which only one operator can be operate or handle the machine. While the machine will begin there is not required more than one or two worker.\u00a0\r\n\r\n2. Reduce the cost: - in the agriculture for cropping the soya bin, javar and tuvar. It can cut cheapest prices because it saves the worker cost.\r\n\r\n3. Reduce the time: - when worker is cutting the crop they have more time for cutting but when the use of the crop cutter harvester they increase the capacity of the working and cutting and it can possible the maximum crop cutting within minimum time.\u00a0\r\n\r\n4. Easy to handle: - crop cutter machine is easy for handling we can easily start the machine.\r\n\r\n5. Unskilled worker can operate: - no skill person required for operating the machine.\r\n\r\n6. Safety to use: - during the working if any problem occurs in the machine we can easily find it.\u00a0\r\n\r\nLIMITATIONS\r\n\r\n1. \u00a0Light weight crops it can\u2019t cut e.g. .Wheat, Rice, Soybean\r\n2. \u00a0Cost is increase when petrol is use.\r\n3. \u00a0Noise pollution.\u00a0\r\n\u00a0\r\nDownload:\r\nCrop Harvester In Agricultural Project Pdf Report Download\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\nAgricultural Project List - Abstract , Report Download\r\nProject Sample report , Final report Download\r\nNew Mechanical Projects 2020 ( All Projects Post Index List )\r\n\r\n\r\n\r\n\r\n\r\n&nbsp;","headline":"CROP HARVESTER IN AGRICULTURAL APPROACH PDF Report Download","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2016-03-03","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2016\/03\/CROPHARVESTINGMACHINEMechanicalagriculturalProject-300x152.jpg","height":152,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/project-abrasive-jet-machining-mechanical-major-project/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2016/03/abrasivejetmachining-300x189.jpg')"></div><span class="sr-only">link to DESIGN AND FABRICATION OF WORKING MODEL OF ABRASIVE JET MACHINE</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/project-abrasive-jet-machining-mechanical-major-project/">DESIGN AND FABRICATION OF WORKING MODEL OF ABRASIVE JET MACHINE</a></p></header><div class="excerpt"><p>Design and Fabrication Of Abrasive Jet Machine Report Download :  ABSTRACT

The material removal process is mainly by erosion. The AJM will chiefly be used to cut shapes in hard and brittle materials like glass, ceramics etc. the machine will be automated to have 3 axes travel. The different components of AJM are Compressor, Vibrator, dehumidifier, Pressure Regulator, and Dust filter, Nozzle, Pressure gauge etc. The different components are selected after appropriate design calculations.\r\n\r\nIn this project, a model of the Abrasive Jet Machine is designed using available hardware and software etc. taking into consideration of commercially available components. Care has been taken to use less fabricated components rather than directly procuring them, because, the lack of accuracy in fabricated components would lead to a diminished performance of the machine.\u00a0\r\n\r\n\u00a0Introduction To AJM:\u00a0\r\nAbrasive Jet Machining (AJM) is Non conventional machining \u00a0the removal of material from a workpiece by the application of a high speed stream of abrasive particles carried in gas medium from a nozzle. The AJM process differs from conventional sand blasting in that the abrasive is much finer and the process parameters and cutting action are carefully controlled. The process is used chiefly to cut intricate shapes in hard and brittle materials which are sensitive to heat and have a tendency to chip easily. The process is also used for debarring and cleaning operations. AJM is inherently free from chatter and vibration problems. The cutting action is cool because the carrier gas serves as a coolant. \u00a0\r\nSee more information : Introduction To Water Jet Machining Process | Advantages and Disadvantages\r\n\r\n\r\n\r\nMachine Parts and Setup :\r\nA schematic layout of AJM is shown in Fig\u2010 The filtered gas, supplied under pressure to the mixing chamber containing the abrasive powder and vibrating at 50 c\/s, entrains the abrasive particle and is the passed into a connecting hose. This abrasive and gas mixture emerges from a small nozzle at high velocity. The abrasive powder feed rate is controlled by the amplitude of vibration of the mixing chamber. A pressure regulator controls the gas flow and pressure.\r\nThe nozzle is mounted on a fixture. Either the workpiece or the nozzle is moved by cams pantograph or other suitable mechanisms to control the size and shape of the cut. Hand operation is sometimes adequate to remove surface contamination or in cutting where accuracy is not very critical. Dust removal equipment is necessary to protect the environment. Commercial bench mounted units including all controls, motion producing devices, and dust control equipment are available.\r\nThe major components are:\r\n\r\n1. Air compressor.\r\n2. Air filter.\r\n3. Dehumidifier.\r\n4. Pressure Gauge.\r\n5. Pressure Regulator.\r\n6. Vibrator or Mixer.\r\n7. Nozzle.\r\n8. Arrangement to hold the work piece.\u00a0\r\n\r\nBlock Diagram of Abrasive water jet machining\r\n\r\nDifferent variables in Abrasive Jet Machine:\r\nThe variables that influence the rate of metal removal and accuracy of machining in this process is:\r\n1. Carrier gas\r\n2. Types of abrasive\r\n3. Size of abrasive grain\r\n4. Velocity of abrasive jet\r\n5. Flow rate of abrasive\r\n6. Work material\r\n7. Geometry, composition and material of nozzle\r\n8. Nozzle work distance (stand off distance)\r\n\r\nActual Assembly Of abrasive jet machining\r\nAdvantages:\r\n1. Low capital cost\r\n2. Ability to cut intricate holes shape in materials of any hardness.\r\n3. Ability to cut heat sensitive material without damage.\r\n4. As no heat is generated in the process, no change in\u00a0micro-structure\r\nLimitations:\r\n1. Material removal rate is low and hence its application is limited.\r\n2. Embedding of the abrasive in the work piece surface may occur while machining softer material.\r\n3. The abrasive material may accumulate at nozzle and fail the process if moisture is present in\u00a0the air.\r\n4. It cannot be used to drill blind holes.\r\n5. Occasional plugging of mixing tube: Usually caused by dirt or large particles in abrasive.\r\n6. Wear, misalignment, and damage to the nozzle.\r\nApplication:\r\n\u00a0The major application of Abrasive jet machining process is in the machining of essentially brittle materials and heat sensitive materials like glass, quartz, sapphire, semiconductor materials, mica and ceramics. It is also used in cutting slot, thin sections, countering, drilling, for producing integrate shapes in hard and brittle materials. It is often used for cleaning and polishing of plastics nylon and Teflon components. Delicate cleaning, such as removal of smudges from antique documents, is also easily done with Abrasive jet machining.\r\nDownload:\r\n\u00a0Abrasive Jet Machining report Download\u00a0\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\nNon traditional machining Projects\r\nProject Sample report , Final report Download\r\nMachine Tool , Manufacturing Projects List - Abstract , Report\r\nNew Mechanical Projects 2020 ( All Projects Post Index List )\r\n\r\n\r\n\r\n&nbsp;","headline":"DESIGN AND FABRICATION OF WORKING MODEL OF ABRASIVE JET MACHINE","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2016-03-03","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2016\/03\/abrasivejetmachining-300x189.jpg","height":189,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/efficiency-increasing-system-in-automobile/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2016/02/automobileefficencyincreasermechanicalproject-300x174.png')"></div><span class="sr-only">link to EFFICIENCY INCREASING SYSTEM IN AUTOMOBILE</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/efficiency-increasing-system-in-automobile/">EFFICIENCY INCREASING SYSTEM IN AUTOMOBILE</a></p></header><div class="excerpt"><p>EFFICIENCY INCREASING SYSTEM IN AUTOMOBILE

Our fore most aim in selecting this project is to use non conventional fuel against conventional fuel which is becoming scarce and costly now days. With this air is less polluted than conventional fuels. It is also good with regard to economical considerations and engine efficiency. In our project, we have installed LPG fuel system to Two\/Four Stroke vehicle\r\nwhere in we can use both gasoline and LPG. The alternations made to install LPG in the vehicle are discussed. LPG from storage tank comes to the adjustable regulator through a primary delivery valve fitted at the mouth of the LPG cylinder. The gas comes by means of rubber hose to solenoid valve which operates in D.C. electronic current. So a separate battery source is used to operate the solenoid valve.\r\n\r\nFrom solenoid valve outlet, separate copper tubes for idle starting and for acceleration are fitted to the carburetor. Unlike petrol engine a separate gravity feed lubrication system is made available since lubricating oil cannot mix with LPG to lubricate the various parts of the engine. Another one is chain sprocket is used to increase the efficiency of the Two\/Four Stroke engine by providing proper chain sprocket. The chain sprocket is used to increase the rpm.\r\n\r\nINTRODUCTION TO GASOLINE FUEL\r\n\r\nGasoline is basically a volatile liquid fuel mixture of hydro carbons. As described already it is a by product during the distillation of crude mineral oil and refining it further by other processes. It does not have a fine composition. The constituents vary depending upon the origin of the crude mineral oil. The important properties of gasoline are given below.\r\n\r\n\r\n\r\nautomobile efficiency increase mechanical project\r\n\r\n\r\n\r\nThe air fuel mixture from the carburetor enters the crankcase through the inlet port during the upward movement of the piston. At the same time the mixture in the cylinder is compressed, which is ignited when the piston is just at T.D.C. The combustion takes place and the piston moves imparting motion to the crankshaft. During the downward movement of the piston the mixture in the crankcase is compressed and pushed into the cylinder through the transfer port, which pushes out the exhaust gases through the exhaust port, at the same time filling the cylinder with a new charge fig . This process is called \u2018CROSS FLOW SCAVENGING\u2019. Thus the whole cycle is completed in Two\/Four Strokes, i.e. one revolution of the crankshaft.\r\n\r\nINTRODUCTION OF CHAIN SPRACKET\r\n\r\nThe chain converts rotational power to pulling power, or pulling power to rotational power, by engaging with the sprocket.\r\n\r\nThe sprocket looks like a gear but differs in three important ways:\r\n1. Sprockets have many engaging teeth; gears usually have only one or two.\r\n2. The teeth of a gear touch and slip against each other; there is basically no slippage in a sprocket.\r\n3. The shape of the teeth is different in gears and sprockets\r\n\r\nDISADVANTAGES OF GASOLINE FUEL\r\n\r\n1. It is one of the costliest liquid fuels.\r\n2. Due to its high calorific value, it produces more heat.\r\n3. In gasoline engine, the fuel does not burn completely and hence carbon deposit in the combustion chamber is more.\r\n4. Compression ratio in gasoline engines can not be increased and hence lesser torque is developed.\r\n5. Residue and oil contamination is more as it burns incompletely and hence decreases engine life.\r\n6. It has lesser octane rating.\r\n7. When burns, it emits poisonous gas called carbon monoxide.\r\n8. Due to incombustible gases, the air is polluted.\r\n9. Gum content is more in gasoline engines.\r\n10. Maintenance cost is more.\r\n11. It gives less mileage when compared with LPG.\r\n\r\nSPECIAL FEATURES OF LPG SYSTEM\r\n\r\n1. LPG is cheaper than gasoline in cost as well availability.\r\n2. It gives better manifold distribution and mixes easily with air.\r\n3. It is highly knock resistant.\r\n4. Residue and oil contamination is small as it burns early.\r\n5. Crank case dilution is small thereby resulting in increased engine life\r\n6. Due to uniform distribution thermal efficiency is higher.\r\n7. LPG has a higher octane rating making it useful in engines having compression ratio above 10:1.\r\n8. It leaves little or no carbon deposits in the cylinder when it burns. It is a clean gas.\r\n9. Easy cold starting is possible due to thermal motion.\r\n10. It has a low strain on lubricants.\r\n11. Lesser exhaust emission and hence lesser air pollution.\r\n12. High durability of exhaust system. Spark plug and upper cylinder.\r\n13. Since it enters as a gas it cannot wash down the cylinder walls. Thus not remove lubricant and so cylinder wall wear, piston rings wear is decreased.\r\n14. Increased engine life.\r\n15. Maintenance costs are lesser.\r\n16. Lean burning is possible.\r\n17. LPG also has an inherent high anti knock value.\r\n18. Due to its less calorific value engine working temperature does not raise much.\r\n19. More mileage by 1 Kg. Of LPG when compared to one litre of gasoline.\r\n20. No need of fuel pump.\r\n21. LPG has minimum gum content.\r\n\r\n\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\nIC Engine Articles , Notes , Question and Answer\r\nAutomobile Engineering Parts and System Notes , Article\r\nMechanical Subjectwise Basic Concept Notes ,Articles\r\n\r\n\r\n\r\n&nbsp;","headline":"EFFICIENCY INCREASING SYSTEM IN AUTOMOBILE","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2016-02-28","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2016\/02\/automobileefficencyincreasermechanicalproject-300x174.png","height":174,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <nav class="pagination-wrapper" aria-label="article pagination"> <a class="prev page-numbers" href="?page_num=277">&laquo; PREV</a> <a class="page-numbers" href="?page_num=1"><span class="screen-reader-text">Page </span>1</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=276"><span class="screen-reader-text">Page </span>276</a> <a class="page-numbers" href="?page_num=277"><span class="screen-reader-text">Page </span>277</a> <span aria-current="page" class="page-numbers current"><span class="screen-reader-text">Page </span>278</span> <a class="page-numbers" href="?page_num=279"><span class="screen-reader-text">Page </span>279</a> <a class="page-numbers" href="?page_num=280"><span class="screen-reader-text">Page </span>280</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=338"><span class="screen-reader-text">Page </span>338</a> <a class="next page-numbers" href="?page_num=279">NEXT &raquo;</a></nav></section></main><aside id="secondary" class="widget-area"><div class="about-wrapper"><h2 class="widget-title" style="background: #d693c6; color: #ff392e">About Us</h2><div class="about-image" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2020/03/Sachin-Thorat-300x300-min.png')"></div><p class="about-copy">LearnMech.Com is a Mechanical Project-oriented platform run by Sachin Thorat who is a B-Tech Graduate in Mechanical Engineering.
