PURPOSE:To raise the air fuel ratio of a combustor and perform good combustion, by defining an exhaust passage between an inner and an outer cylinders and providing the combustor in the inner cylinder and conducting a part of exhaust gas to the combustor. CONSTITUTION:Under the low-load rapid rotation, high-pressure air is introduced into a passage P, a piston 9 is moved forth and a control valve 2 is also moved forth. Simultaneously, an inlet port 7 is opened and connected to the exhaust passage A and an outlet port 14 is closed. Thus, the exhaust gas flows from the inlet port 7 into the inner cylinder 3 and is conducted to the combustor 5. Thereby, the air fuel ratio in the combustor 5 is raised and good combustion is effected. |
