Active pre-combustion chamber combustion control method and system, air inlet cam shaft and vehicle

Abstract

The invention discloses an active pre-combustion chamber combustion control method and system, an air inlet cam shaft and a vehicle. The method comprises the steps that ignition operation is conducted on a pre-combustion chamber; inlet air with different flow speeds is generated by utilizing an air inlet cam shaft with different lifts, air inlet vortices are generated according to the inlet air with the different flow speeds, and the air inlet vortices are coupled with flames generated by ignition operation. The intake camshaft with different lifts is used for controlling the intake flow rates of different intake valves respectively, so that intake vortexes are generated, the circular motion of airflow is enhanced, the intake vortexes are coupled with flames generated by the pre-combustion chamber, the diffusion speed of the flames can be increased, the detonation occurrence rate in the ignition process of an engine is reduced, and the ignition efficiency of the engine is improved. The engine heat efficiency is improved.
