Gasoline - diesel dual fuel powered engine and pre-mixed charge compression ignition control method thereof

HCCI mixed combustion of P-mCCI (Pre-mixed Charge Compression Ignition) control method of the present invention is the air (+ EGR gas), and the gasoline fuel supplied from Premixed intake stroke, creating a premix atmosphere, leading to for at least separated by a second step the supply of diesel fuel in compression ignition stroke is to form a flame acts as ignition trigger (trigger), with forming a compression ignition combustion atmosphere of a diesel, it is supplied from the intake stroke in the following expansion stroke is burned is a gasoline fuel to form a mixed atmosphere of by giving to produce power, combustion instability in accordance with the ignition timing and a combustion control difficulties, as well as practical by eliminating all of the knocking (knocking), including limiting the power performance diesel-gasoline composite fuel engine It characterized to implement.
