Performance and Emissions Trade-Offs for a HSDI Diesel Engine - An Optimization Study

Experimental data and analytical techniques are used to study the trade-offs between emissions and performance for a turbocharged, intercooled HSDI diesel engine equipped with an electronically controlled exhaust gas recirculation (EGR) system. Measured data are used to support a thermodynamically based cycle simulation comprising a multi-zone combustion and emission model. The simulation is used to investigate the effects of various key parameters including fuel injection equipment (FIE) on engine performance and emissions.
