普通铁路直喷(CRDI)的注意事项

  • 术语 'CRDI.’ commonly refers to柴油发动机。虽然,存在类似的技术petrol engines也使用它是已知的作为汽油直接注射(GDI)或燃料分层注射(FSI)。
  • 这两种技术都在设计中具有相似性,因为它们由普通的“燃料导轨”组成,该普通的“燃料导轨”提供给喷射器的燃料。然而,它们在所使用的压力和类型的燃料中彼此相差地不同。
  • 普通铁路直喷,开始燃烧直接进入主燃烧室位于活塞冠顶部的空腔中。
  • 今天,制造商使用CRDI.技术克服了一些deficiencies of conventional diesel engines which were sluggish, noisy and poor in performancewhen implemented especially in passenger vehicles.
  • CRD-i technology用发动机串联工作ecu.which gets inputs from various sensors.
  • 公共铁路系统使用“common-for-all-cylinders’ fuel-rail or in simple words a ‘fuel distribution pipe’.

  • 它保持最佳剩余燃料压力and also acts as a shared fuel reservoir for all the injectors.
  • CRDI.系统,燃料轨不断储存和供应在所需压力下燃料到电磁阀注射器。
  • 在早期一代(DI)设计的情况下,这与燃料喷射泵供应柴油直通的独立燃料管的燃料喷射泵与喷射器相反。

Components of CRDi System –

  1. High Pressure Fuel Pump
  2. 共同燃油铁轨
  3. 注射器
  4. Engine Control Unit

CRDI的工作 -

  • 高压泵产生加压燃料。
  • 泵在约1,000巴或约15,000psi的压力下压缩燃料。
  • It, then, supplies the pressurised fuel via a high-pressure pipe to the inlet of the fuel-rail.
  • 从那里,燃料轨道将其分配给单独的喷射器,然后将其注入气缸的燃烧室。

CRDI的优点和缺点

好处

CRDI发动机在许多方面是有利的。据信适用于这种新的发动机技术的汽车,可以提供25%的功率和扭矩,而不是正常直接喷射发动机。它还提供卓越的拾取,较低的噪音和振动,更高的里程,降低排放,降低燃料消耗和提高性能。

在印度,柴油比汽油便宜,这一事实增加了公共铁路直喷系统的可信度。

Disadvantages

就像所有好东西都有消极的一面,这个引擎也有很少的缺点。CRDI发动机的关键缺点是它比传统发动机昂贵。该清单还包括高度发动机维护和昂贵的备件。此技术也不能用于普通发动机。

Applications

这most common applications of common rail engines are marine and locomotive applications. Also, in the present day they are widely used in a variety of car models ranging from city cars to premium executive cars.

一些印度汽车制造商在各自的汽车模型中广泛接受使用共轨柴油发动机是现代电机,Maruti铃木,菲亚特,通用汽车,本田电机和斯柯达。在豪华汽车制造商名单中,梅赛德斯 - 奔驰和宝马还采用了这种先进的发动机技术。所有汽车制造商都给了他们自己的独特名字,以普通的CRDI发动机系统。
