吸気加熱装置。[Claims for Utility Model Registration] A heating device including a heater and a nozzle that supplies fuel for heating the intake air to the heater is disposed in the intake system of an internal combustion engine, and the combustion of the internal combustion engine is carried out through a fuel injection nozzle. In a combustion-type intake air heating device, in which fuel supplied from a fuel supply pump to a fuel injection pump that injects fuel into a chamber or a part of the fuel introduced into the fuel injection pump is supplied to the heating device as fuel for heating the intake air. , The intake air heating fuel supply passage that supplies the intake air heating fuel to the heating device includes a solenoid valve that opens and closes the intake air heating fuel supply passage, and a flow rate of the intake air heating fuel on the upstream side of the solenoid valve. A throttle member is provided between the intake air heating fuel supply passage and the electromagnetic valve to restrict excess intake air heating fuel to the fuel tank. 1. A fuel-type intake air heating device, characterized in that one end of an intake air heating fuel return passage is connected to a check valve for maintaining the pressure of the intake air heating fuel at a predetermined value.
