Engine control method, engine control device, vehicle and storage medium

Abstract

The invention provides an engine control method, an engine control device, a vehicle and a storage medium. The engine control method is applied to a target vehicle, and an ignition assembly is arranged on an engine cylinder of the target vehicle; the ignition assembly comprises a pre-combustion chamber and a target fuel injector arranged in the pre-combustion chamber. The method comprises the steps that if an opening signal of an accelerator pedal in a target vehicle is detected, the first fuel injection quantity of an engine cylinder body is determined; based on the operation parameters of the engine, the total gas amount of the engine cylinder block is determined; the total gas quantity is used for indicating the sum of waste gas quantity and gas inlet quantity; the ratio of the first fuel injection quantity of the engine cylinder body to the total gas quantity is determined as the mixed gas concentration of the engine cylinder body; based on the mixed gas concentration and the target volume of the pre-combustion chamber, the target fuel injection quantity of a target fuel injector is determined so as to control operation of the engine; wherein the target volume of the pre-combustion chamber is used for indicating the effective volume of the pre-combustion chamber. According to the method, the oil injection quantity in the pre-combustion chamber can be accurately controlled, and then the oil consumption of the engine is reduced.
