置。When the engine is cold and in an operating range below a predetermined load or rotation, the exhaust throttle valve installed in the exhaust passage is closed by a predetermined opening degree to apply load to the engine, thereby increasing the thermal energy generated by the engine. In the exhaust throttle valve control device for a diesel engine,
An opening operation control device is provided which causes the exhaust throttle valve to open slowly until a predetermined time period has elapsed during the initial opening operation of the exhaust throttle valve, and to rapidly open the exhaust throttle valve after the predetermined time period has elapsed. A diesel engine exhaust throttle valve control device featuring:
