The Effect of Different Injection Strategies and Intake Conditions on the Emissions Characteristics in a Diesel Engine

الملخص EN

Choosing various injection strategies and intake conditions are potentially effective techniques to reduce exhaust emission from diesel engines.

The purpose of this study is to investigate the effect of different spray incoming angles, different spray cone angles, different injection timing, and different intake temperatures together with emission characteristics on a heavy duty diesel engine via three dimensional computational fluid dynamics (CFD) procedures.

Furthermore the effect of multiple injector combustion chamber and its benefits in pollutant reduction is studied.

The principal results show the significant differences in soot and NO generation during combustion between above different strategies.
