Variable valve internal combustion engine starting control method

Abstract

The invention belongs to a variable valve internal combustion engine starting control method and relates to the technical field of starting of an internal combustion engine. The method is started from reducing the large torsion and large current when the internal combustion engine is started, and the gas compressing resistance when the internal combustion engine is reduced by controlling the work of a variable valve execution mechanism and a starter, so the match power of the existing starting system is greatly reduced, the copper use level of the starter and lead use level of a storage battery are reduced, the pollution of heavy metals to the environment is reduced and the matching cost of the starting system is also reduced.

Description

technical field [0001] The invention relates to a starting control method of a variable-valve internal combustion engine, which relates to the technical field of starting internal combustion engines. Background technique [0002] At present, due to the pressure of environmental protection, people have done a lot of research on the combustion system of internal combustion engines, and proposed many technical solutions to improve the combustion conditions of internal combustion engines, improve the fuel economy of internal combustion engines, and reduce emissions. Valve technology, it has become a standard configuration of the car. But at present, people only pay attention to the fuel and emission conditions when the internal combustion engine is running normally, but ignore the working conditions when the internal combustion engine starts. At present, the starting conditions of the internal combustion engine are: the starting torque is large, the required starting current is...

But at present, people only pay attention to the fuel and emission conditions when the internal combustion engine is running normally, but ignore the working conditions when the internal combustion engine starts

At present, the starting conditions of the internal combustion engine are: the starting torque is large, the required starting current is large, and the internal combustion engine is developing towards high power, which leads to a large matching power of the starting system, resulting in a large amount of copper used by the starter and lead used by the battery in the starting system. Increase the pollution of heavy metals while consuming resources
