ABSTRACT:
Variable closed position fuel and air flow control for vehicles with automatic transmission for improving fuel consumption efficiency of a vehicular internal combustion engine, without disabling or circumventing any engine function, accessory, or emission control device, by causing the engine to idle at substantially constant speed regardless of changes in the engine load caused by accessories such as automatic transmission, air conditioning, power steering and the like. This variable closed position fuel and air flow control device is adapted to be easily retrofitted to existing engines and includes a vacuum actuator connected to be responsive to changes in pressure in the fuel and air flow induction passage for the engine. A cam is operatively associated with the primary idle stop of the antidieseling solenoid and the throttle control arm and a linkage transmits the motion of the actuator to the cam. The inventive control apparatus provides fuel conservation in automobiles with automatic transmission and powered accessories under conditions of standstill idle and when the vehicle is driving the engine and the throttle control arm rests against its stop at the closed position. Fuel savings are effected significantly in stop and go driving such as encountered by taxicabs in congested city traffic, and fuel savings are also obtained during highway driving in hilly terrain.
