Abstract
In a combustor for supplying combustion heat to a heater core and an intake side of an engine, when the engine is started, combustion gas is supplied to an intake side of the engine while non-combustion air is introduced into a combustion gas passage partitioned from a water passage of the heater core by a heat-conduction partition member. In this case, non-combustion air is used as an air curtain for interrupting a heat transmission from the combustion gas of the combustion gas passage to water of the water passage.
