置。In an exhaust throttle valve control device for a diesel engine that includes an exhaust throttle valve disposed in the exhaust passage and an actuator that opens and closes the exhaust throttle valve, the exhaust throttle valve is substantially fully closed when the engine is stopped and warmed up or when the exhaust brake is applied. The exhaust throttle valve is opened to the first set opening degree when the stop warm-up or the exhaust brake is applied to the traveling heating time, and then the exhaust throttle valve is opened to the first set opening degree or less and to the above-mentioned substantially full opening degree. 1. An exhaust throttle valve control device for a diesel engine, comprising actuator control means for opening the throttle valve to a second set opening degree, which is a throttle valve opening degree during running heating, which is larger than the throttle valve opening degree in a closed state.
