Abstract
An E.G.R. control system for a diesel engine is disclosed wherein a deterioration in combustion is avoided upon depressing an accelerator pedal for reacceleration after the momentary release of the accelerator pedal. An E.G.R. control unit is responsive to a load indicative signal from a load sensor and a revolution signal from a revolution sensor and generates an engine operating state indicative signal indicating that the engine operates in low load state which requires high E.G.R. flow rate. A monostable circuit, a delay circuit and a logic circuit make up a circuit means for preventing a throttle valve from being closed until the engine keeps operating in the low load state for a time longer than a predetermined time.
