Abstract
A power plant system particularly useful for hybrid vehicles driven by electric motors, the power plant system including a positive displacement engine with a bifurcated exhaust forming first and second exhaust passages for expansion gases, each passage being separately controlled by an independently operated engine exhaust valve, the first exhaust passage supplying expansion gases to a turbine connected to a compressor delivering compressed air to the engine and the second exhaust passage supplying expansion gases to a turbine connected to an electric generator, the power plant system having a system control module independently controlling each exhaust valve for optimum air compression for the load and speed of engine operation.
Claims10
A power plant comprising:
- a.) a positive displacement engine having a combustion chamber in which are generated expansion gases, an air intake system and an expansion gas exhaust system, the exhaust system having a first exhaust passage and a second exhaust passage, the engine having a first valve means between the combustion chamber and the first exhaust passage for regulating passage of expansion gases from the combustion chamber to the first exhaust passage and a second valve means between the combustion chamber and the second exhaust passage for regulating passage of expansion gases from the combustion chamber to the second exhaust passage;
- b.) a first turbine connected to the first exhaust passage;
- c.) a compressor mechanically connected to the first turbine, the compressor being connected to the air intake system of the engine;
- d.) a second turbine connected to the second exhaust passage;
- e.) an electrical generator mechanically connected to the second turbine;
- and,
- f.) valve control means for independently controlling the operation of the first valve means and the second valve means, and flow regulating means connected to the valve control means for adjustably regulating the allocation of expansion gases between the first and second passages, wherein the regulating means regulates the quantity of exhaust gases passing through the first exhaust passage for optimized compression of air by the compressor and for fuel efficient operation of the engine.
A power plant comprising:
- a.) a positive displacement engine comprising an opposed piston engine having a combustion chamber in which are generated expansion gases, an air intake system and an expansion gas exhaust system, the exhaust system having a first exhaust passage and a second exhaust passage, the engine having a first valve means for regulating passage of expansion gases from the combustion chamber to the first exhaust passage and a second valve means for regulating passage of expansion gases from the combustion chamber to the second exhaust passage;
- b.) a first turbine connected to the first exhaust passage;
- c.) a compressor mechanically connected to the first turbine, the compressor being connected to the air intake system of the engine;
- d.) a second turbine connected to the second exhaust passage;
- e.) an electrical generator mechanically connected to the second turbine;
- f.) control means for separately controlling the operation of the first valve means and the second valve means and regulating flow of expansion gases into the first and second passages, wherein compression of air by the compressor is optimized by the control means for fuel efficient operation of the engine, wherein the engine has an output shaft and the power plant has a main generator connected to the output shaft of the engine, and wherein the power plant includes an electric drive motor and an integrator, wherein the generator connected to the turbine and the main generator connected to the output shaft of the engine are electrically connected to the integrator and the integrator is connected to the electric drive motor;
- and,
- g.) an electrical energy storage means for storing electrical energy generated by the generators wherein the integrator regulates distribution of generated electricity to the energy storage means and to the electric drive motor.
