Abstract

PURPOSE: To suppress the emission of noise, HC, CO and actively control the emission of NOx from a diesel engine, by providing an injection rate control means for increasing a fuel injection rate at the opening action of a control valve controlling recirculation of exhaust gas.
CONSTITUTION: Intake and exhaust sides 7, 6 of a diesel engine 1 are communicated by an exhaust gas recirculating passage 5 having a control valve 10. Exhaust gas recirculation and fuel injection rate are controlled by a control circuit 4 input with a load and speed of the engine, when a command P is transmitted from the control circuit 4, the control valve 10 is opened to start recirculating operation of exhaust gas. Simultaneously, the control circuit 4 transmits a command 9, then fuel is boosted its pressure by a fuel injection pump 3, injected from a fuel injection nozzle 2 and increased the fuel injection rate.
