Early Injection Strategy for Low-emission Premixed-Combustion Engine: Comparison
View Latest Version
Please note this is a comparison between Version 2 by Peter Tang and Version 1 by liang xingyu.

Low-emission and high-efficiency have always been the targets for Internal Combustion Engine development. For diesel engines, homogeneous charge (aka. HCCI) and premixed charge (aka. PCCI) combustion modes provide both low-emission and high-efficiency simultaneously. To achieve these advanced combustion modes, early injection is needed as a relatively longer air-fuel mixing time is guaranteed. Several key parameters, such as the injection timing, pressure, angle, directly determine the final combustion process and thus the emission and efficiency performance. The pros and cons of these key parameters are discussed in detail here to provide a good review of the early-injection strategy.

  • PCCI
  • Internal Combustion Engine
  • Diesel Engine
  • NOx
  • Soot
