Abstract
The main components of vehicle diesel engine emissions are nitrogen oxides and particulates. The emissions concept adopted for pressure-wave supercharging with controlled EGR and particulate trap, focuses on both components. In conjunction with electronic EGR-control the spontaneous response of the supercharger achieves minimum deviations from optimum air excess values, even during transients. In the US city cycle an NOx reduction to 35 % of the reference emission, without sacrificing fuel economy was established. Featuring a particulate trap arranged between engine and supercharger this system increases the regeneration probability and as a result of the improved supercharsinp, efficiency achieves satisfactory transient behavior, Catalytic coating of the rotor constitutes an additional means of reducing emissions.
