Abstract
In a cylinder deactivation control method of an engine, a cylinder deactivation trigger moment of a to-be-controlled engine is determined; a second cycle and a cylinder deactivation mode corresponding to the next first cycle are determined according to the crankshaft rotation speed at the cylinder deactivation trigger moment, the target torque at the cylinder deactivation trigger moment, and a second cycle and a cylinder deactivation mode corresponding to the previous first cycle at the cylinder deactivation trigger moment; the fuel injection quantity of the ignition cylinder in the next first cycle is determined.
