ABSTRACT:
A power and deceleration governor for automotive engines according to the present invention, may conveniently take the form of a carburetor power and deceleration system incorporating an intake manifold, vacuum controlled, butterfly type mixture flow control valve, that is disposed downstream of an idle system injection outlet of a carburetor for an automotive engine. The flow control valve is operative to terminate injection of fuel mixture into the intake manifold of the engine during phases of the engine deceleration to allow full flow of idle fuel mixture during idling of the engine and to restrict the flow of fuel mixture during acceleration above a predetermined maximum rate. The system may also incorporate means for metering exhaust gases from the exhaust manifold of the engine to the intake manifold downstream of the flow control valve of the power and deceleration and governor system. A sliding cylinder release valve, the position of which is controlled by the throttle shaft of the engine, allows a manifold vacuum energized disphragm motor to control the position of the butterfly valve responsive to the pressure condition of vacuum in the intake manifold. The deceleration governor system may also incorporate an idle override system that opens the butterfly throttle valve when the engine reaches idle speed and allows engine operation to continue through the conventional function of the carburetor idle circuit.
