INTERNAL COMBUSTION ENGINE

摘要

An internal combustion engine, wherein a fuel injection valve (6) and an ignition plug (7) are disposed in a combustion chamber (5), fuel is injected from the fuel injection valve (6) at the end of a compression stroke, the amount of soot produced reaches a peak when the amount of EGR gas is increased and, when the amount of EGR gas is increased further, to the contrary, no soot is produced, whereby, because the amount of EGR gas in the combustion chamber (5) is increased over that produced when the amount of soot produced reaches a peak, the production of soot in the combustion chamber (5) is suppressed.
