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, depending on the engine performance, and a resuming controller for resuming the disabled cylinders one at a time when switching from the cylinder-disabling mode to the all-cylinders-engaged mode, thereby allowing for continuous and smooth switching between the cylinder-disabling mode and the all-cylinders-engaged mode.
