Abstract

See full text

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 current first cycle at the cylinder deactivation trigger moment; the cylinder pressure type of each cylinder in the current first cycle is determined in conjunction with the cylinder deactivation modes of three adjacent first cycles; the fuel injection quantity of each ignition cylinder in the current first cycle is determined based on the calibrated preset fuel injection quantity chart of the first cycle.
