Exhaust gas recirculation is an effective means to reduce NOx-emissions of Diesel engines. Unfortunately too high EGR rates increase the emissions of hydrocarbons, carbon monoxide and soot. So EGR has to be controlled precisely.The paper describes an EGR-system for Diesel engines which senses the air-flow and the fuel-flow of the engine and limits the EGR-rate so, that the air-fuel-ratio is lean enough for a clean combustion.Furthermore the paper shows the emission results which have been obtained with the described EGR-system on different Diesel passenger cars.
