Abstract

Experimental research on performance and emission of the CA498 vehicle direct-injection DME engine by means of two kinds of exhaust gas recirculation (EGR) scheme is carried out. Test results indicate that NO_x emission decreases with the rise of EGR ratio in two schemes and NO_x emission decreases sharply by scheme 2 in which NO_x emission decreases about 40% at 20% EGR ratio with less penalty on the brake thermal efficiency of DME engine. CO emission of DME engine drops greatly with oxidation catalytic reactor as the after-treatment at all operating conditions. Experiments prove that it is efficient for controlling NO_x emission by EGR and controlling CO emission by oxidation catalytic reactor on DME engine.
