Research Progress of Designation and Effect of Pre-chamber to Lean-burn of Natural Gas Engine
Lean-burn in internal combustion engine(ICE)is supposed to be a kind of mode both with energy conservation and emission reduction.The ignition and combustion character of traditional Spark-ICE in lean-burn mode are introduced,and the effect of pre-chamber system to the process of ignition,combustion and emission generation during natural gas combustion is discussed.After that,domestic and foreign research around the pre-chamber parameters of construction and arrangement have been discussed,which is supposed to be reference for research and development(R&D) of new natural gas engines.
