PURPOSE:To prevent back flow of temperature-raised air and to improve efficiency by providing a deflecting member at a connection part between a temperature-raised air passage and an intake passage so as to deflect in-flow direction of the temperature- raised air from a turbo-heater flowing from the temperature-raised air passage to the intake passage of an engine to the side of the engine. CONSTITUTION:A control valve 9 is arranged in an exhaust passage 3, and the upper and the lower parts of the control valve 9 are connected to each other by a bypass passage 10. Also, in the bypass passage 10, a turbine 7 of a turbo-heater 4 is arranged. Moreover, an air intake passage 11 connected to a blower 8 of the turbo-heater 4 is connected to an intake passage 2 in the neighborhood of an air cleaner 5 through an auxiliary intake passage 12, and a discharge passage 13 from the blower 8 is connected into a car 15 through a temperature-raised air passage 14. In this case, at a connection part 19 between the temperature-raised air passage 14 and the intake passage 2, a deflecting member 20 for deflecting the flow of a temperature-raised air is fixed at the inner wall of the intake passage 2 so that, the in-flow direction of the temperature raised air from the turbo heater 4 flowing into the intake passage 2 is deflected to the side of an engine body 1. |
