INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a technology capable of preventing lubricating oil from being diluted due to secondary injection in a cylinder injection internal combustion engine. SOLUTION: When the secondary injection is carried out before and after a main injection, an oil heater 26 is operated with an ECU300 to increase the temperature of lubricating oil so that a gasifiable fuel component of fuel mixed into lubricating oil is increased. Thus, dilution of the oil is reduced. COPYRIGHT: (C)2004,JPO&NCIPI
