ABSTRACT:
A compression ignition type engine, which switches between a first combustion where the amount of the inert gas in the combustion chamber is larger than the amount of inert gas where the amount of production of soot peaks and almost no soot is produced and a second combustion where the amount of inert gas in the combustion chamber is smaller than the amount of inert gas where the amount of production of soot peaks. The second combustion is provided instead of the first combustion when a catalyst is not activated.
