Description
Technical field
The present invention relates to a kind of purposes of hydrogen fuel, and the rotary engine that realizes this purposes.
Background technique
According to statistics, in artificial atmospheric pollution sources, have 80% carbon monoxide to result from the combustion process of internal-combustion engine approximately, 95% carbon monoxide comes from the burning of all types motor fuel, and internal-combustion engine in use discharges to initiation and surpasses 40% volatile organic matter.Hydrogen is as a kind of renewable clean fuel, not only solved the harm that the carbon containing emission of substance brings, and the hydrogen-fueled internal combustion engine thermal efficiency is very high, discharging is almost near zero, production and user cost are low, are easier to be accepted by users at aspects such as usability, costs.
In the prior art, do the reciprocating-piston engine that the motor car engine of fuel adopts with hydrogen, adopt external mixture type or internal-mixing hydrogen supply, there are problems such as tempering, pre-ignition, underpower in this motor, so far the also good solution of neither one.
Rotary engine is by Felix wankel doctor invention, and is the same with reciprocating engine, and rotary engine also is the pressure that utilizes air, fuel mixture burning to produce.The working principle of rotary engine is that the summit of rotor contacts with housing, thereby forms three independently air chambers.Ceaselessly around the firing chamber motion, the gas of three kinds of volumes alternately expands and shrinks rotor.This just expansion and contraction suck motor with air and fuel, then this mixed gas is compressed, and generate useful power when gas expands, last combustion gas.
Summary of the invention
The rotary engine that goal of the invention of the present invention is to provide a kind of purposes of hydrogen fuel and realizes this purposes can effectively be utilized hydrogen fuel, solves tempering, pre-ignition, underpower problem that hydrogen-fuel engine exists.
The present invention is based on same inventive concept, have two independently technological schemes:
1, a kind of purposes of hydrogen fuel is characterized in that: the fuel that hydrogen fuel is used for rotary engine.
2, a kind of rotary engine that realizes aforementioned hydrogen fuel purposes has rotor and housing, has suction port and relief opening on the housing, it is characterized in that: also have hydrogen inlet on the housing.
Hydrogen inlet is positioned at the top of housing.
It is indoor that high pressure hydrogen regularly is injected to the cylinder that rotor and housing form by hydrogen inlet.
It is indoor that air is inhaled into cylinder by shell air inlet.
The hydrogen air jet system inserts hydrogen inlet by pipeline.
Air jet system comprises hydrogen cylinder, hydrogen voltage stabilizing gas rail, and hydrogen cylinder is connected by pipeline with hydrogen voltage stabilizing gas rail; Hydrogen voltage stabilizing gas rail is provided with snifting valve, and snifting valve switches through the hydrogen inlet of sub-motor body by the road; Hydrogen cylinder is provided with solenoid valve, and this solenoid valve is controlled by controller.
Motor hydrogen supply mode can adopt external mixture type hydrogen supply mode.
The beneficial effect that the present invention has:
The present invention makes the application technology of hydrogen-fuel engine improve a new stage, and hydrogen fuel is used for rotary engine, has solved reciprocating-piston engine and has used guardian technique problems such as the long-term indeterminable tempering of hydrogen fuel, pre-ignition, underpower.Because hydrogen rotary engine of the present invention air inlet and burning are separately carried out, so avoided tempering phenomenon; The hydrogen rotary engine can adopt the mode of straight spray hydrogen in the firing chamber, so the pre-ignition phenomenon should not take place; Hydrogen rotary engine intake stroke is longer, helps the mixing of air and hydrogen.The experiment proved that, regularly spraying under the hydrogen state that adopt the high pressure spray hydrogen mode of 8～10MPa, engine power has improved nearly 1.5～1.8 times than existing reciprocating piston hydrogen engine, tempering and pre-ignition phenomenon also do not occur.
The Nox emission problem of hydrogen rotary engine of the present invention can solve by increasing EGR, owing to there is not other fuel draining, and very environmental protection and being applicable on hybrid vehicle/pure electric vehicle.The present invention can be used as the mileage pressurized machine of pure electronic, hybrid vehicle, has reduced the energy consumption that drives battery, effectively increases distance travelled.
Hydrogen rotary engine of the present invention adopts hydrogen to act as a fuel than adopting other petrochemical industry hydrocarbon fuel more can evade some shortcomings, as sufficient combustion and emission problem.Simultaneously, the present invention makes the utilization and the industrialization of pollution feuls such as hydrogen fuel and the alternative gasoline of other biofuel feasible fully, saves the energy, reduces environmental pollution.
