Dual fuel combustion system based on diesel compression ignition triggered ignition control

A method for a diesel-gasoline dual fuel premixed charge compression ignition combustion system based on diesel compression ignition triggered ignition control, comprising a stroke cycle including:

• a premixed charge intake stroke completed at an intake stroke completing time point after a premixed surroundings of a combustion chamber for premixed charge compression ignition is started by supplying a gasoline fuel mixed with air and EGR gas into the combustion chamber at the premixed charge intake stroke starting time point;
• a compression ignition stroke starting at the premixed charge intake stroke completing time point, where after a diesel fuel is injected into the combustion chamber until a time point before compression ignition, or diesel fuel is injected once again into the combustion chamber at a compression ignition time point;
• a combustion expansion stroke where the gasoline fuel injected into the combustion chamber is ignited by the another injection of the diesel fuel and flames of the gasoline fuel propagate into a space of the combustion chamber;
• and
• an exhaust stroke returning to the premixed charge intake stroke, where combustion gas generated after the gasoline fuel is burned is discharged to the outside.
