A first combustion mode in which an amount of an EGR gas within a combustion chamber is higher than that of the EGR gas when a generated amount of soot reaches a peak and substantially no soot is generated. A second combustion mode in which the amount of the EGR gas within the combustion chamber is lower than that of the EGR gas when the generated amount of soot reaches the peak are selectively performed. A catalyst is disposed within an engine exhaust passage wherein a temperature of the catalyst is adjusted so as to be within a predetermined range.

[ What is claimed is:] [1.]1. An internal combustion engine having an exhaust passage and a combustion chamber, the engine gradually increases a generated amount of soot to a peak amount by increasing an amount of inert gas supplied to the combustion chamber, comprising:an inert gas amount controller that controls the amount of inert gas supplied to the combustion chamber so that the supplied amount is more than an amount of the inert gas that causes generation of the soot to reach the peak amount;a catalyst provided in the exhaust passage of the engine, the catalyst performing an oxidation function;a detector that detects a temperature of the catalyst; anda catalyst temperature adjuster that adjusts the temperature of the catalyst so that the catalyst temperature is within a predetermined temperature range.
