Summary

Starting with the role that the diesel engine plays in achieving fleet CO₂ targets now and in the future, this paper discusses the subject of diesel engine emission compliance, which has lately fallen under heavy criticism. To this end, this paper will examine the following areas for their potential to achieve further reductions in CO₂ and emissions. o combustion and inner-engine temperature management o aftertreatment concepts o base engine variability o further potential in combination with electrification Based on those considerations, the future diesel engine should be defined with respect to technical features as well as size, additionally taking into account the whole drivetrain. The diesel engine will remain a crucial element in achieving an affordable CO₂ fleet strategy in the future, especially in consideration of the market trend toward SUV and cross-over concepts. Particularly where the heavier vehicle classes are concerned, the diesel combustion concept does in fact make it possible to combine efficiency with environmental compatibility and driving pleasure – even under real-world operating conditions.
