<P>PROBLEM TO BE SOLVED: To lower the temperature of combustion gas without adding air from the exterior in a combustion assisting turbo supercharging device having a burner. <P>SOLUTION: The assistant combustion turbo supercharging device, in which a supercharger 2 is operated at high speed by joining high temperature gas from a burner 4 to an exhaust gas of engine 1 includes, as a means for adjusting a discharge of incoming air passing an air cooler 3, a by-pass passage a4, a control valve Vb of the by-pass passage and a control valve Vc directly linked with the cooler, and gas temperature in the burner is lowered by suppressing heat dissipation by the air cooler 3 with the control valves. The device can be operated economically and stably. The operating condition of the burner can be kept more appropriately by adjusting the by-pass rate of air depending on load condition. <P>COPYRIGHT: (C)2007,JPO&INPIT |
