ABSTRACT:
An internal combustion engine having a carburetor equipped with the usual throttle valve means controlling the flow of air-fuel flow to the intake manifold is provided with a normally open cut-off valve means located between the throttle valve and intake manifold to close communication therebetween when it is moved to closed position. A vehicle speed responsive device is operatively connected to the cut-off valve to move it to the closed position whenever the vehicle is coasting or moving under closed throttle valve conditions at or below a predetermined vehicle speed. In addition, there is provided a conduit between the intake manifold and the crank case with a pivoted plate clapper type check valve therein to permit flow from the crank case into the intake manifold.
