CIRCUIT FOR CONTROLLING THE OPERABILITY OF ONE OR MORE CYLINDERS OF A MULTICYLINDER INTERNAL COMBUSTION ENGINE ABSTRACT Circuit for controlling the operability of one or more cylinders of a multicylinder internal combustion engine having electrically controllable means associated with it for preventing combustion from occurring in at least one cylinder of the engine. Preferably, the electrically controllable means for preventing combustion in a cylinder comprises a solenoid and associated mechanical means for preventing opening of the intake and exhaust valves for such cylinder to be thus disabled. Main- taining the intake and exhaust valves in a closed condition prevents the intake of an air-fuel mixture and permits compression and expansion, in a spring-like manner, of gases trapped within the combustion chamber. Electrical circuit means are provided for sensing a plurality of conditions of operation of the engine and logic circuit means, responsive to the sensing circuit means, are provided for controlling the actuation of the means for preventing combustion from occurring in the cylinder or cylinders selected for disable, ment.
