Abstract
A turbo compound engine includes a generator for converting the exhaust energy of an internal combustion engine to electric energy and a motor operatively coupled to the output shaft of the internal combustion engine and drivable by the electric energy generated by the generator, so that the energy of the internal combustion engine can be recovered. The torque produced by the internal combustion engine is assisted dependent on the speed of rotation of the output shaft of the engine.
Claims4
A turbo compound engine having a first exhaust turbine coupled to an exhaust pipe of an internal combustion engine and a second exhaust turbine coupled to an exhaust port of the first exhaust turbine;
- comprising:
- a first generator drivable by said first exhaust turbine;
- a second generator drivable by said second exhaust turbine;
- a motor operatively coupled to an output shaft of said internal combustion engine;
- speed detecting means for detecting the speed of rotation of said internal combustion engine;
- and
- control means for controlling the frequency of electric power, which is the sum of electric power outputs from said first and second generators and supplied to said motor, based on a signal from said speed detecting means, in order to control operation of said motor.
