<P>PROBLEM TO BE SOLVED: To prevent a surge of a hybrid exhaust turbine supercharger, by controlling a rotational speed of the hybrid exhaust turbine supercharger with a simple constitution, without using an expensive control device for instantly processing a complicated operation. <P>SOLUTION: This supercharging device includes: at least one exhaust turbine supercharger 6 having a turbine part 6a and a compressor part 6b and always put in an operation state when an engine body 2 is operated; at least one hybrid turbine supercharger 7 having a turbine part 7a, a compressor part 7b and a generator 29 and put in a parallel operation state with the exhaust turbine supercharger 6 when the engine body 2 is operated; and a controller C mounted on the exhaust turbine supercharger 6, receiving a signal from a rotation sensor for detecting a rotational speed of the exhaust turbine supercharger 6, issuing a command signal to the generator 29 according to its signal and controlling the amount of electric power generated by the generator 29 so that the rotational speed of the hybrid exhaust turbine supercharger 7 and the rotational speed of the exhaust turbine supercharger 6 agree with each other. <P>COPYRIGHT: (C)2010,JPO&INPIT |
