Inventor: AKEDA MASAHIRO
IPC: F02B23/06
Filed: 2000-03-10
Abstract: PROBLEM TO BE SOLVED: To lower a peak of the pressure increasing rate of cylinder internal pressure by causing a flash of a main injection fuel by an auxiliary combustion flame to smoothly start combustion, and to strengthen heating power of the auxiliary combustion flame by heightening the evaporation capability of the auxiliary injection fuel. SOLUTION: First, the auxiliary injection fuel 3 is forced to collide with the outer peripheral wall surface of a combustion chamber 2, thereby forming a fuel liquid film 3a. A part of the fuel liquid film 3a is evaporated by holding heat of the outer peripheral wall surface part 6 to form evaporated air fuel mixture. Secondly, in a process where a squish flow 17 descends in the central part in the combustion chamber 2 to form a tumble flow 18, the tumble flow 18 blows off a number of fuel liquid particles from the fuel liquid film 3a to be evaporated while being stirred and mixed, thereby heightening the mixing concentration of the evaporated air fuel mixture to a combustible region, and the air fuel mixture is ignited by compression heat to start auxiliary combustion.  By the thus generated auxiliary combustion flame, flash of the main injection fuel starting main injection is caused to start combustion.
