It has been shown that by the application of a proportion of exhaust gas to the inlet air of a light duty diesel engine the NOx emission in the exhaust can be substantially reduced. This report describes a system of exhaust gas recirculation, modulated to reduce the NOx emission of a Mercedes 300D light duty diesel vehicle, to within defined limits of other parameters, such as HC and CO emissions, and performance loss, etc. To offset losses in performance due to the application of EGR, a turbo charger was fitted to the vehicle to provide excess air. No extra fuel was supplied. (Peters)
