HCCI is not an engine concept. HCCI must be incorporated in an engine concept.\r\n \tHCCI is a low temperature chemically controlled (flameless) combustion process.\r\n \tHCCI can be considered as a hybrid form between the diesel and Otto combustion process.\r\n \tHowever combustion process is different. So there is neither Diffusion flame (as in a diesel engine) nor a flame front traveling through a premixed charge ( as in SI engine).\r\n\r\nRead also :\u00a0What is Lean Burn Engine | Working , Advantages and Disadvantages\r\n\r\nWhy HCCI Engine ?\r\n\r\n \tHigh efficiency and ultra low emission with respect to conventional Diesel engine.\r\n \tTo achieve near zero NOx and soot emission\r\n \tTo achieve latest Euro Norms ( E5)\r\n \tTo reduce fuel consumption, greenhouse gas emission.\r\n\r\nLaw of Diesel HCCI \u2013\r\n\r\n \tEvery one percent increase of diesel HCCI car saves 90 million liters of fuel per year.\r\n \tThis corresponds to emission saving of some 210000 metric tones of CO2\r\n\r\nHCCI Engine\r\nWORKING PRINCIPLE OF HCCI\r\nHomogenous charge is drawn in to the cylinder during suction and compress to high enough temperature to achieve spontaneous ignition of the charge. Combustion starts in almost whole volume of C.C Two degree before TDC After Combustion initiation the temperature rapidly increases and whole fuel burn simultaneously As whole mixture burns simultaneously and no flame propagation , combustion temperature can be controlled less than 700 deg Centigrade and thus NOx formation is avoided.\r\nHCCI Drawbacks\r\n\r\n \tHigher load HCCI operation is difficult.\r\n \tTo achieve Transient operation and cold starting are issues.\r\n \tStart of combustion (SOC) is difficult to control because there is no direct ignition source such as a spark plug or fuel injection timing.\r\n \tInstead SOC is controlled by mixture properties at intake valve closing.\r\n \tControlling how rapidly the energy is released is also a problem. For this reason significant EGR dilution is needed.\r\n \tCO and UHC emissions are also high at light loads\r\n\r\nHCCI Benefits\r\n\r\n \tUltra-low NOx emissions because there is no propagating flame front and the burning is both locally and globally lean.\r\n \tExtremely low PM emissions because the mixture is homogeneous and there are no rich pockets\r\n \tSignificant part load efficiency gains over SI because the engine is operated unthrottled and load is controlled by fuelling and varying the fuel to air ratio.\r\n \tHomogeneous Charge Compression Ignition (HCCI) engines have the potential of producing a high thermal efficiency with extremely low PM and NOx emissions.\r\n\r\n\r\n\r\n\r\nMore Resources :\u00a0\r\nIC Engine Articles , Notes , Question and Answer\r\nMechanical Subjectwise Basic Concept Notes ,Articles\r\n\r\n\r\n\r\n\r\n&nbsp;","headline":"What is HCCI Engine | Working , Advantages and Disadvantages","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-04-17","mainEntityOfPage":"False","dateModified":"February 19, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/04\/HCCI-Engine-300x162.png","height":162,"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/what-are-the-factors-influencing-flame-speed-in-i-c-engines/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/04/time-vs-equivailent-ratio-graph-300x190.jpg')"></div><span class="sr-only">link to What are the factors influencing flame speed in I.C. engines?</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/what-are-the-factors-influencing-flame-speed-in-i-c-engines/">What are the factors influencing flame speed in I.C. engines?</a></p></header><div class="excerpt"><p>What are the factors influencing flame speed in I.C. engines?

There are several factors which affect the flame speed, to a varying degree, the most important being the turbulence and the fuel-air ratio. Details of various 'factors \u00b7that affect the flame speed are discussed below.\r\nTurbulence:\r\n\r\n \tThe flame speed is quite low in non-turbulent mixtures and increases with increasing turbulence. This is mainly due to the additional physical intermingling of the burning and unburned particles at the flame front which expedites reaction by increasing' the rate of contact.\r\n \tThe turbulence in the incoming mixture is generated during the admission of fuel-air mixture through comparatively narrow sections of throttle pipe, valve openings etc., in the suction stroke. Turbulence which is supposed to consist of many minute swirls appears to increase the rate of reaction and produce a higher flame speed than that made up of larger and fewer swirls. A suitable design of the combustion chamber which involves the geometry of cylinder head and piston crown increases the turbulence during the compression stroke.\r\n \tGenerally, turbulence increases the heat flow to the cylinder wall. It also accelerates the chemical reaction by intimate mixing of fuel and oxygen so that spark advance may be reduced. This helps in working in lean mixtures also. The increase of flame speed due to turbulence reduces the combustion duration and hence minimizes the tendency of abnormal combustion. However, excessive turbulence may extinguish the flame resulting in rough and noisy operation of the engine.\r\n\r\nFuel-Air Ratio:\r\n\r\n \tThe fuel-air ratio has a very significant influence on the flame speed. The highest flame velocities (minimum time for complete combustion) are obtained with somewhat richer mixture (point A) as shown in Fig.12.4 which shows the effect of mixture strength on the rate of burning as indicated by the time taken for complete burning in a given engine. When the mixture is made leaner or richer (see point A in Fig.12.4) the flame speed decreases. Less thermal energy is released in the case of lean mixtures resulting in lower flame temperature.\r\n \tVery rich mixtures lead to incomplete combustion which results again in the release of less thermal energy.\r\n\r\ntime vs equivalent ratio graph\r\nTemperature and Pressure:\r\n\r\n \tFlame speed increases with an increase in intake temperature and pressure. A higher initial pressure and temperature may help to form a better homogeneous air-vapour mixture which helps in increasing the flame speed. This is possible because of an overall increase in the density of the charge.\r\n\r\nCompression Ratio:\r\n\r\n \tA higher compression ratio increases the pressure and temperature of the working mixture which reduce the initial preparation phase of combustion and hence less ignition advance is needed. High pressures and temperatures of the compressed mixture also speed up the second phase of combustion.\r\n \tIncreased compression ratio reduces the clearance volume and therefore increases the density of the cylinder gases during burning. This increases the peak pressure and temperature and the total combustion duration is reduced.Thus engines having higher compression ratios have higher flame speeds.\r\n\r\nEngine Output:\r\n\r\n \tThe cycle pressure increases when the engine output is increased. With the increased throttle opening the cylinder gets filled to a higher density. This results in increased flame speed.When the output is decreased by throttling, the initial and final compression pressures decrease and the dilution of the working mixture increases. The smooth development of self-propagating nucleus of flame becomes unsteady and difficult.\r\n \tThe main disadvantages of SI engines are the poor combustion at low loads and the necessity of mixture enrichment (\u00a2 between 1.2 to 1.3) which causes wastage of fuel and discharge of unburnt hydrocarbon and the products of incomplete combustion like carbon monoxide etc. in the atmosphere.\r\n\r\nEngine Speed:\r\n\r\n \tThe flame speed increases almost linearly with engine speed since the increase in engine speed increases the turbulence inside the cylinder. The time required for the flame to traverse the combustion space would be halved, if the engine speed is doubled.\r\n \tDouble the engine speed and hence half the original time would give the same number of crank degrees for flame propagation. The crank angle required for the flame propagation during the entire phase of combustion, will remain nearly constant at all speeds.\r\n\r\nEngine Size:\r\nThe size of the engine does not have much effect on the rate of flame propagation. In large engines the time required for complete combustion is more because the flame has to travel a longer distance. This requires increased crank angle duration during the combustion. This is one of the reasons why large sized engines are designed to operate at low speeds.\r\n\r\n\r\n\r\nMore Resources :\u00a0\r\nIC Engine Articles , Notes , Question and Answer\r\nMechanical Subjectwise Basic Concept Notes ,Articles\r\n\r\n\r\n\r\n\r\n&nbsp;","headline":"What are the factors influencing flame speed in I.C. engines?","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-04-17","mainEntityOfPage":"False","dateModified":"February 19, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/04\/time-vs-equivailent-ratio-graph-300x190.jpg","height":190,"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/what-is-lean-burn-engine-working-advantages-and-disadvantages/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/04/lean-engine-268x300.jpg')"></div><span class="sr-only">link to What is Lean Burn Engine | Working , Advantages and Disadvantages</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/what-is-lean-burn-engine-working-advantages-and-disadvantages/">What is Lean Burn Engine | Working , Advantages and Disadvantages</a></p></header><div class="excerpt"><p>What is Lean Burn Engine | Working , Advantages and Disadvantages

It is a lean amount of fuel supplied to and burned in an engine's combustion chamber. Normal air-to-fuel ratio is on the order of 15:1 (15 parts air to 1 part fuel). True lean-burn can go as high as 23:1.\r\n\r\nLean-burn engines (both gasoline and diesel) enjoy higher fuel economy and cleaner emissions than conventionally tuned engines. By nature they use less fuel and emit fewer unburned hydrocarbons and greenhouse gases while producing equivalent power of a like-sized \"normal\" combustion engine. They achieve leanburn status by employing higher combustion chamber compression ratios (higher cylinder pressure), significant air intake swirl and precise lean-metered direct fuel injection.\r\n\r\nlean burn engine\r\n\r\n \tA lean burn mode is a way to reduce throttling losses.\r\n \tAn engine in a typical vehicle is sized for providing the power desired for acceleration, but must operate well below that point in normal steady-speed operation. Ordinarily, the power is cut by partially closing a throttle.\r\n \tHowever, the extra work done in pumping air through the throttle reduces efficiency.\r\n \tIf the fuel\/air ratio is reduced, then lower power can be achieved with the throttle closer to fully open, and the efficiency during normal driving (below the maximum torque capability of the engine) can be higher.\r\n \tThe engines designed for lean burning can employ higher compression ratios and thus provide better performance, efficient fuel use and low exhaust hydrocarbon emissions than those found in conventional petrol engines.\r\n \tUltra lean mixtures with very high air-fuel ratios can only be achieved by direct injection engines.\r\n \tThe main drawback of lean burning is that a complex catalytic converter system is required to reduce NOx emissions.\r\n \tLean burn engines do not work well with modern 3-way catalytic converter which requires a pollutant balance at the exhaust port so they can carry out oxidation and reduction reactions so most modern engines run at or near the stoichiometric point.\r\n \tAlternatively, ultra-lean ratios can reduce NOx emissions\r\n\r\nAdvantages of lean burn engine\r\n\r\n \tHigher fuel economy\r\n \tEmit fewer unburned hydrocarbons and greenhouse gases\r\n \tA lean burn mode is a way to reduce throttling losses\r\n\r\nDisadvantages of lean burn engine\r\n\r\n \tLean burning is that a complex catalytic converter system is required to reduce NOx emissions.\r\n \tHigh relatively cost\r\n\r\n\r\n\r\n\r\nMore Resources :\u00a0\r\nIC Engine Articles , Notes , Question and Answer\r\nMechanical Subjectwise Basic Concept Notes ,Articles\r\n\r\n\r\n\r\n\r\n&nbsp;","headline":"What is Lean Burn Engine | Working , Advantages and Disadvantages","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-04-17","mainEntityOfPage":"False","dateModified":"February 19, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/04\/lean-engine-268x300.jpg","height":300,"width":268},"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/what-is-gasoline-direct-injection-gdi-working-operation/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/04/What-is-Gasoline-Direct-Injection-300x221.jpg')"></div><span class="sr-only">link to What is Gasoline Direct Injection (GDI) | Working Operation</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/what-is-gasoline-direct-injection-gdi-working-operation/">What is Gasoline Direct Injection (GDI) | Working Operation</a></p></header><div class="excerpt"><p>What is Gasoline Direct Injection (GDI) | Working Operation

The gasoline is highly pressurized, and injected via a common rail fuel line directly into the combustion chamber of each cylinder, as opposed to conventional multi-point fuel injection that happens in the intake tract, or cylinder port.\r\n\r\nOperation\r\n\r\nThe major advantages of a GDI engine are increased fuel efficiency and high power output. Emissions levels can also be more accurately controlled with the GDI system. The cited gains are achieved by the precise control over the amount of fuel and injection timings that are varied according to engine load. In addition, there are no throttling losses in some GDI engines, when compared to a conventional fuel-injected or carbureted engine, which greatly improves efficiency,\u00a0 and reduces 'pumping losses' in engines without a throttle plate. Engine speed is controlled by the engine control unit\/engine management system (EMS), which regulates fuel injection function and ignition timing, instead of having a throttle plate that restricts the incoming air supply. Adding this function to the EMS requires considerable enhancement of its processing and memory, as direct injection plus the engine speed management must have very precise algorithms for good performance and drivability.\r\n\r\nThe engine management system continually chooses among three combustion modes: ultra-lean burn, stoichiometric, and full power output.\r\n\r\nUltra lean burn or stratified charge mode is used for light-load running conditions, at constant or reducing road speeds, where no acceleration is required. The fuel is not injected at the intake stroke but rather at the latter stages of the compression stroke. The combustion takes place in a cavity on the piston's surface which has a toroidal or an ovoidal shape, and is placed either in the centre (for central injector), or displaced to one side of the piston that is closer to the injector. The cavity creates the swirl effect so that the small amount of air-fuel mixture is optimally placed near the spark plug. This stratified charge is surrounded mostly by air and residual gases, which keeps the fuel and the flame away from the cylinder walls. Decreased combustion temperature allows for lowest emissions and heat losses and increases air quantity by reducing dilation, which delivers additional power. This technique enables the use of ultra-lean mixtures that would be impossible with carburettors or conventional fuel injection.\r\n\r\n\r\nStoichiometric mode is used for moderate load conditions. Fuel is injected during the intake stroke, creating a homogeneous fuel-air mixture in the cylinder. From the stoichiometric ratio, an optimum burn results in a clean exhaust emission, further cleaned by the catalytic converter.\r\n\r\n\r\nFull power mode is used for rapid acceleration and heavy loads (as when climbing a hill). The air-fuel mixture is homogeneous and the ratio is slightly richer than stoichiometric, which helps prevent detonation (pinging). The fuel is injected during the intake stroke.\r\n\r\nWhat is Gasoline Direct Injection\r\n\r\n\r\n\r\nMore Resources :\u00a0\r\nIC Engine Articles , Notes , Question and Answer\r\nMechanical Subjectwise Basic Concept Notes ,Articles\r\n\r\n\r\n\r\n\r\n&nbsp;","headline":"What is Gasoline Direct Injection (GDI) | Working Operation","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-04-17","mainEntityOfPage":"False","dateModified":"February 19, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/04\/What-is-Gasoline-Direct-Injection-300x221.jpg","height":221,"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 no-thumb"><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/natural-gas-as-engine-fuel-advantages-and-disadvantages/">Natural Gas as Engine Fuel | Advantages and Disadvantages</a></p></header><div class="excerpt"><p>Natural Gas as Engine Fuel | Advantages and Disadvantages

It is a renewable energy source, like solar and wind energy. Furthermore, biogas can be produced from regionally available raw materials and recycled waste and is environmentally friendly and CO2 neutral. \r\n\r\nBiogas is produced by the anaerobic digestion or fermentation of biodegradable materials such as manure, sewage, municipal waste, green waste, plant material, and crops. Biogas comprises primarily methane (CH4) and carbon dioxide (CO2) and may have small amounts of hydrogen sulphide (H2S), moisture and siloxanes.\r\n\r\nThe gases methane, hydrogen, and carbon monoxide (CO) can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel. Biogas can be used as a fuel in any country for any heating purpose, such as cooking. It can also be used in anaerobic digesters where it is typically used in a gas engine to convert the energy in the gas into electricity and heat. Biogas can be compressed, much like natural gas, and used to power motor vehicles.\r\n\r\nRead also ;\u00a0Biodiesel -Fuel In IC Engine | Advantages and Disadvantages\r\n\r\nbogas generator set\r\n\r\nAdvantages of Biogas Energy\r\n\r\n \tIt\u2019s a renewable source of energy.\r\n \tIt\u2019s a comparatively lesser pollution generating energy.\r\n \tBiomass energy helps in cleanliness in villages and cities.\r\n \tIt provides manure for the agriculture and gardens.\r\n \tThere is tremendous potential to generate biogas energy.\r\n \tBiomass energy is relatively cheaper and reliable.\r\n \tIt can be generated from everyday human and animal wastes, vegetable and agriculture left-over etc.\r\n \tRecycling of waste reduces pollution and spread of diseases.\r\n \tHeat energy that one gets from biogas is 3.5 times the heat from burning wood.\r\n \tBecause of more heat produced the time required for cooking is lesser.\r\n\r\nDisadvantages of Biogas Energy\r\n\r\n \tCost of construction of biogas plant is high, so only rich people can use it.\r\n \tContinuous supply of biomass is required to generate biomass energy.\r\n \tSome people don\u2019t like to cook food on biogas produced from sewage waste.\r\n \tBiogas plant requires space and produces dirty smell.\r\n \tDue to improper construction many biogas plants are working inefficiently.\r\n \tIt is difficult to store biogas in cylinders.\r\n \tTransportation of biogas through pipe over long distances is difficult.\r\n \t\u00a0Many easily grown grains like corn, wheat are being used to make ethanol.\r\n \tThis can have bad consequences if too much of food crop is diverted for use as fuel.\r\n \tCrops which are used to produce biomass energy are seasonal and are not available over whole year.\r\n\r\n\r\n\r\n\r\nMore Resources :\u00a0\r\nIC Engine Articles , Notes , Question and Answer\r\nMechanical Subjectwise Basic Concept Notes ,Articles\r\n\r\n\r\n\r\n\r\n&nbsp;","headline":"Biogas as Fuel in IC Engine | Advantages and Disadvantages","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-04-17","mainEntityOfPage":"False","dateModified":"February 19, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/04\/bogas-generator-set-300x214.jpg","height":214,"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=65">&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=64"><span class="screen-reader-text">Page </span>64</a> <a class="page-numbers" href="?page_num=65"><span class="screen-reader-text">Page </span>65</a> <span aria-current="page" class="page-numbers current"><span class="screen-reader-text">Page </span>66</span> <a class="page-numbers" href="?page_num=67"><span class="screen-reader-text">Page </span>67</a> <a class="page-numbers" href="?page_num=68"><span class="screen-reader-text">Page </span>68</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=67">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.
