Combined Effects of Piston Bowl Geometry and Fuel Injection Strategies on Emissions of a Diesel Engine
Piston bowl geometry and different fuel injection strategies are important factors affecting emissions in a DI diesel engine,which have been numerically analyzed in this paper.Under the premise of ensuring chamber volume,compression ratio,total injection amount and total injection duration,this paper analyses the emissions of a diesel engine with three different fuel injection strategies and four different piston bowl geometries.The results show that multiple injection and change of combustion chamber shape have a significant impact on diesel engine emissions.
