Abstract

The present invention provides a control method, device, equipment and readable storage medium for a special hybrid engine. The method includes: when the pure power generation mode is turned on or the direct drive vehicle operation mode is turned on, adjusting the speed and load of the engine so that the adjusted speed and load are in the SIAI region stimulated by spark ignition; controlling the engine to use the SIAI combustion method Work. Through the present invention, the engine is controlled to work in the SIAI combustion mode only when the adjusted rotational speed and load are in the SIAI region stimulated by the spark ignition to stimulate the self-ignition of the mixed gas, thereby avoiding combustion instability and knocking in the SIAI combustion mode of the hybrid special engine The situation, and compared with the SI combustion method, the fuel economy is better.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a control method, device, equipment and readable storage medium for a special hybrid engine. Background technique [0002] At present, the common combustion method of gasoline engines is spark ignition SI, but this method has poor fuel economy. In order to improve the fuel economy, the spark ignition stimulates the self-ignition of the mixture and the SIAI combustion method is proposed. However, the SIAI combustion method cannot achieve stable compression ignition in the low-load region, and has the problem of knocking in the high-load region. Contents of the invention [0003] The main purpose of the present invention is to provide a hybrid special engine control method, device, equipment and readable storage medium, aiming to solve the technical problems of instability and knocking in the SIAI combustion mode in the prior art. [0004] In a first aspect, the present i...
