Description

technical field [0001] The invention relates to the technical field of hybrid vehicles, in particular to a method and device for controlling a gasoline engine for hybrid vehicles. Background technique [0002] With the increasingly stringent fuel consumption regulations, research on the thermal efficiency of gasoline engines has gained more and more attention. At present, most vehicles still use spark-ignition gasoline engines. The thermal efficiency of traditional spark-ignition gasoline engines is low. If you want to improve the traditional spark-ignition gasoline engines, you need to face disadvantages such as high technical difficulty and high material cost. Therefore, the problem of low thermal efficiency of the gasoline engine needs to be solved urgently. Contents of the invention [0003] The embodiment of the present application solves the technical problem of low thermal efficiency of gasoline engines in the prior art by providing a control method and device for ...
