Abstract
Description
technical field
[0001] The invention relates to a control technology of an electronically controlled fuel injection internal combustion engine. Background technique
[0002] Most of the design displacements of existing engines are fixed values. Regardless of the load during operation, all displacements are involved in the work. According to the principle of internal combustion engine, when the load rate is small, the specific fuel consumption is high, and the emission pollution is relatively large; when the load rate is large, the specific fuel consumption is small, and the emission pollution is also small. For example, gasoline engines generally have the lowest specific fuel consumption and least emission pollution when the load rate is about 80-90%. The power of the engine installed on the car is equipped according to extreme working conditions such as the maximum speed at full load, or the maximum gradient. In most usage situations, such as driving in urban areas, the ...
