Description

technical field [0001] The invention belongs to the field of combustion control of homogeneous mixed gas, and in particular relates to a system for mechanically assisting compression control of internal combustion engines to control homogeneous mixed gas combustion. Background technique [0002] Homogeneous compression ignition refers to a combustion process in which fuel and air are uniformly mixed in advance during the intake process, and the combustible gas is evenly mixed during the compression stroke. When the piston moves to the vicinity of the top dead center, the homogeneous mixture gas naturally ignites. Compared with traditional internal combustion engines, homogeneous compression ignition not only maintains the characteristics of high power per liter of gasoline engines, but also maintains the advantages of high thermal efficiency of diesel engines. Although homogeneous compression ignition has these advantages, it also faces a series of problems such as the di...
