Abstract
A cylinder-disabling control system for a multi-cylinder engine provided with an exhaust manifold to which each exhaust port is connected, which control system comprises: an engine performance sensor; an operation mode selector for selecting the cylinder-disabling mode or the all-cylinders-engaged mode; and a disabled-cylinder designator for designating as disabled at least one of the most upstream cylinder and the exhaust pulse-affected downstream cylinder, when the cylinder-disabling mode is selected, thereby improving driving stability at low rpm's.
