PROBLEM TO BE SOLVED: To effectively utilize combustion heat without exerting a bad influence upon an intake air system structure by the combustion heat of a combustion type heater even if the combustion gas of a combustion type heater is introduced in the intake air system of an internal combustion engine. SOLUTION: An engine 1 with combustion type heater 17 for raising the temperature of cooling water by actuating in a specified operation state of the engine 1 is provided a combustion gas introduction pipe 19 for introducing the combustion gas fed by the combustion type heater 17 to the external peripheral face 9a of the outside air introducing pipe 9 of the engine 1 and a plurality of combustion gas introducing holes 29, which are formed in the external peripheral face 9a of the outside air introducing pipe 9 and introduce the combustion gas inside the outside air introducing pipe 9 when the combustion gas is introduced to the external peripheral face 9a of the outside air introducing pipe 9. |
