Saito, H

Disclosed is an exhaust gas recirculation apparatus for an internal combustion engine, which has a vacuum operated flow control valve arranged on pipe means connecting the exhaust manifold of the engine with the intake manifold of the engine. When the throttle valve is opened from its idle position during the operation of the engine, the flow control valve is opened in order to recirculate exhaust gas from the exhaust manifold to the intake manifold. The apparatus further has means for opening the flow control valve when so-called dieseling takes place after the operation of the engine is stopped. The exhaust gas due to the dieseling can be recirculated and, thus, the dieseling is instantly stopped.
