Summary

The market share of passenger cars equipped with Diesel engines has risen dramatically in recent years. This trend was supported by the Diesel engine’s feature to combine fuel economy with sporty driving performance. The fact that this development was accompanied by a significant eduction of pollutant emission constitutes an additional bonus in the Diesel engine’s image. The challenge for the on-going development of the passenger car Diesel engine is the fulfillment of ever tightened emission legislation without deterioration of economy and performance. Without a further reduction of engine-out emissions the fulfillment of future emission legislation scenario makes the usage of a 4-way catalytic converter (CO, HC, particulate matter, NOx) mandatory. A further reduction of raw emission by alternative or also conventional combustion systems needs the application of optimized injection-, EGR-, cooling and supercharging systems. The paper describes the evolution of the Diesel engine from the past until today and as an example onhand of an advanced supercharging system how this can serve not only for emission reduction but also reduces fuel consumption and improves driving performance at the same time. The thereby achieved added value makes additional costs for advanced charging system attractive for the customer.
