Abstract
A multiple cylinder engine having an intake passage for each cylinder. A shut-off valve or valves are provided in the intake passage or passages leading to selected one or ones of cylinders downstream of the throttle valve. The shut-off valve is closed in idling operation so that the combustible mixture is totally supplied to the remainder of the cylinders to increase the mixture charge therein. The intake passage or passages leading to the selected cylinder or cylinders are supplied with air when the shut-off valves are closed so that the peak pressure in such cylinders is increased. The air supply is cut-off in deceleration in order for preventing the engine-brake effect from being weakened.
