の排気還流制御装置。The exhaust recirculation rate is controlled by controlling the opening degree of a throttle valve installed in the intake passage and an EGR control valve installed in the exhaust recirculation passage connecting the intake passage and the exhaust passage downstream of the throttle valve. The air recirculation control device for a diesel engine is configured to include a control means for detecting atmospheric pressure and maintaining the throttle valve in an open state over the entire operating range of the engine when the atmospheric pressure drops below a predetermined value. Features a diesel engine exhaust recirculation control device.
