ABSTRACT:
An internal combustion engine having a combustion heater is constructed to prevent an influence by a blow-by gas and to maintain well the combustion in the combustion heater even when introducing the combustion air of the combustion heater from an intake passage of the internal combustion engine. The combustion heater introduces a fuel by using a pump and the air from an air introducing passage by using a fan, and thus performs a combustion. The air introducing passage is connected to an intake passage. A blow-by gas introducing passage is connected to the intake passage. An aperture, connected to the intake passage, of the blow-by gas introducing passage is disposed more downstream of an intake flow than an aperture, connected to the intake passage, of the air introducing passage. With this configuration, an inflow of the blow-by gas into the combustion heater is restrained, and the combustion can be well maintained.
