The valve comprises a valve casing, disposed in the intake line of the engine, of a rectangular cross sectional shape. A valve seat connected to an exhaust line of the engine via an EGR passageway is formed in a side wall of the rectangular shaped valve casing. A valve member of a plate shape is arranged in the casing and is rotated about an axis located upstream of the valve seat in such a manner that the valve member is moved between a position wherein the plate closes the valve seat and another position wherein the plate closes the intake passageway. The valve device is operated by an actuator means including a vacuum actuator connected to the valve plate and a vacuum generator which transmits a vacuum signal into the actuator in accordance with the load of the engine.

摘要： The intake pressure and temperature of a Diesel engine equipped with a supercharger are sensed and the sensed intake pressure value is divided by the sensed intake temperature value to obtain an intake density. A value indicative of the intake density is divided by a value indicative of the air-excess ratio computed in accordance with the operating condition of the engine producing a smoke-limit injection amount. The smoke-limit injection amount is compared with the injection amount corresponding to a part-load condition of the engine and the smaller one of the values is applied to a linear solenoid for controlling the fuel injection amount adjusting member in the fuel injection pump of the engine.
