Abstract

An environment-friendly engine system is characterized by that hydrogen gas that fuels the engine is generated from water by electrolysis and that the electric power for electrolysis is supplied by a fuel cell in a water fuel tank and a leadacid cell connected in parallel with the fuel cell. As the engine system is operating, the fuel cell burns methyl alcohol or ethyl alcohol to generate power for activating water electrolysis that produces hydrogen gas. The hydrogen gas fuels a hydrogen engine, and the steam produced in the engine is used to drive an electricity generator and subsequently a turbine, whereby the electricity is stored in a leadacid cell used together with the fuel cell. Thereby, the engine system is safe to operate and produces no any of the greenhouse gases, truly friendly to the environment.

Claims

1. An environment-friendly engine system, comprising:

a hydrogen engine fueled by a mixture of hydrogen gas and air, said hydrogen gas being supplied by a hydrogen storage bottle, said mixture being ignited to burn so as produce mechanical power, steam produced in combustion being used to drive at least an electricity generator and a subsequent turbine;

a hydrogen generator powered by batteries for activating an electrolysis of water whereby said hydrogen gas is generated, said hydrogen gas being transported to said hydrogen storage bottle; and

a cooling exhausting system for cooling down and ejecting water and waste gases produced by said hydrogen engine and said batteries.

2. The environment-friendly engine system of claim 1 further comprising an air filtering system for treating oxygen gas and ozone gas produced by said electrolysis of water and injecting said oxygen gas into said hydrogen engine with an appropriate amount, thereby reducing the consumption of air;

said oxygen gas and said ozone gas being added through said air filtering system into a passenger space of an automobile for improving air quality.

3. The environment-friendly engine system of claim 1 wherein said batteries of said hydrogen generator comprises at least a fuel cell and a leadacid cell.

4. The environment-friendly engine system of claim 2 wherein water used by said hydrogen generator is supplied by a water fuel tank.

5. The environment-friendly engine system of claim 3 wherein said fuel cell situates within said water fuel tank.

6. The environment-friendly engine system of claim 2 wherein said leadacid cell is for storing the electricity generated by said electricity generator.

7. The environment-friendly engine system of claim 3 wherein a water filter is mounted between said water fuel tank and said hydrogen generator.

8. The environment-friendly engine system of claim 2 wherein methyl alcohol and ethyl alcohol can be added into said fuel cell through a common pipeline for fuel addition and exhausting waste gases;

waste water produced by said fuel cell being collected in said water fuel cell for reuse.

9. The environment-friendly engine system of claim 1 can be used in an automobile and used with a gasoline-based engine system.

10. The environment-friendly engine system of claim 8 further comprising a backup water fuel tank;

said backup water fuel tank it being capable of balancing the load of a car and being used as a cushioning thing in a car accident.

11. The environment-friendly engine system of claim 1 wherein said hydrogen storage bottle is further provided with a piston, whereby said piston will block a gas outlet of said hydrogen storage bottle if said hydrogen storage bottle was flipped as a result of a turnover of said car.
