An internal combustion engine (3) having a combustion heater (17) is constructed to prevent a thermal damage to the structure of an intake system (5) due to combustion heat emitted from the combustion heater (17). The engine includes the combustion heater (17) operating at a cold time. Cooling water is warmed by heat of combustion gas emitted from the combustion heater (17) when in combustion, thereby speeding up a warm-up of the engine and enhancing a performance of a car room heater (9) of a vehicle mounted with the engine. In the thus constructed internal combustion engine (3) having the combustion heater (17), fresh air entering an intake air passageway of the engine is mixed with the combustion gas of the combustion heater (17), whereby the fresh air becomes a combustion gas mixed intake air toward an engine body. A temperature of the combustion gas mixed intake air is obtained, and a combustion state of the combustion heater (17) is controlled based on this temperature. <IMAGE> |
