INTERNAL COMBUSTION ENGINE

A fuel injector (6) and a spark plug (7) are arranged inside a combustion chamber (5) of an internal combustion chamber. Fuel is injected from the fuel injector (6) at the end of the compression stroke. When the amount of EGR gas is increased, the amount of production of soot peaks. When the amount of EGR gas is further increased, soot is no longer produced. The amount of EGR gas in the combustion chamber (5) is made larger than the amount of EGR gas where the amount of production of soot peaks. Due to this, the production of soot in the combustion chamber (5) is suppressed.
