INTERNAL COMBUSTION ENGINE

摘要

An engine where first combustion where the amount of the EGR gas in the combustion chamber is larger than the amount of EGR where the amount of production of soot peaks and almost no soot is produced and a second combustion where the amount of EGR gas in the combustion chamber (5) is smaller than the amount of EGR gas where the amount of production of soot peaks are selectively switched between. When switching between the first combustion and second combustion, the injection timing is delayed until after top dead center of the compression stroke.
