PURPOSE:To prevent a power transmission means from being damaged, by switching the power transmission means which connects the crankshaft of an engine and a turbine for recovering the exhaust energy discharged from an exhaust turbosupercharger in rotatable manners in the normal and reverse directions, to the reverse revolution after the lapse of a prescribed time. CONSTITUTION:As for the title engine, the exhaust energy discharged from an exhaust turbosupercharger 2 is recovered by a turbine 4, and the axial turn ing moment is supplied into a crankshaft 5, and the high output of the engine 2 is obtained. The turbine 4 and the crankshaft 5 are connected in rotatable manners in the normal and reverse directions by a planetary gear device and a power transmission means 6 equipped with a hydraulic clutch for operating the planetary gear device. A driving power which is necessary for the switching between the normal and reverse revolutions is supplied into the power transmis sion means 6 from a pressure feeding means 8. In this case, the power transmis sion means 6 is provided with a switching control means 7 for the switching to the reverse revolution by gradually increasing the pressure for the hydraulic clutch within a prescribed time. |
