排気ガス再循環制御装置。An exhaust throttle valve that changes the effective exhaust cross-sectional area of the exhaust gas passage, an actuator that drives the exhaust throttle valve, and a control device that controls the drive of the actuator based on the detection outputs of a group of sensors that detect various operating states of the diesel engine. When the engine starts, when the engine load is in the light load range and the engine cooling water temperature is below the low temperature setting temperature,
An exhaust gas recirculation control device for a diesel engine, characterized in that, by driving an actuator, an exhaust throttle valve is operated in a direction in which an effective exhaust cross-sectional area of an exhaust gas passage is reduced, thereby suppressing exhaust gas discharge.
