    Abstract: Experimental study was conducted on NOX emissions law of a heavy diesel engine with EGR and SCR. Opening of EGR valve (OEV) was adjusted by INCA, and ammonia nitrogen ratio (ANR) was changed by controlling urea injection quantity with control unit DCU of SCR. Under low, medium and high speed and 50%, 75% and 100% load conditions, the effect of EGR ... Show More
