Summary

The challenge for the HSDI Diesel engine lies in fulfilling the most severe emission legislation. This has to be achieved without deterioration in overall economy maintaining attractive vehicle performance. Without further reduction of engine-out emissions the application of a 4-way catalytic converter (CO, HC, particulates and NOx) will be mandatory. If engine out-emissions can be reduced significantly e.g. by alternative combustion systems with cylinder pressure guided combustion control and/or the application of optimised super-charging systems, an exhaust gas aftertreatment concept consisting of oxidation catalyst and particle filter will be sufficient for certain vehicle-engine-combinations. The control of charge condition and mixture homogenisation necessary for the emission reduction is realised by geometrical compression ratio, boosting and EGR system as well as the fuel injection equipment. The engine control input needs to be extended at least by a combustion signal.
