It connects, the check valve B is connect with the inlet manifold.
The hydrogen loading fuel combustion hydrogen supply and stocking system, when the device for producing hydrogen generates surplus hydrogen
When, air accumulator is installed between the pneumatic operated valve A and the pressure maintaining valve.
The utility model has the beneficial effects that
1. the utility model, instead of solenoid valve control, avoids generating electric spark in hydrogen pipeline using pneumatic operated valve
Danger, while device for producing hydrogen is used, tradition is solved for hydrogen cylinder hydrogen storage safety and transport problem.
2. the utility model by pressure maintaining valve and control nozzle injection pulse width, precisely adjusts hydrogen loading tolerance and spray regime is mixed
It is good to close effect；When internal combustion engine does not work, this system is closed, survival gas pressure release eliminates in system to tank is depressurized in pipeline
Remaining high pressure hydrogen storage and security risk, while check valve is installed on hydrogen feed pipe road, prevents internal combustion engine tempering to system pipes
Cause danger in road.
3. the utility model uses air accumulator, the surplus hydrogen of device for producing hydrogen generation can be recycled, and can be in internal combustion
Initial stage offer sufficient hydrogen is provided machine next time, guarantees that hydrogen supplies continuity.
4. the novel specific works method of reality:
(1) when the engine operates, device for producing hydrogen generates high-temperature hydrogen, becomes room temperature hydrogen through over-heat-exchanger, pneumatically
After valve A is opened, room temperature hydrogen filters impurity that may be present by combustion gas filter, protects element in pipeline, and hydrogen passes through steady
Room temperature constant pressure after pressure valve imports combustion gas rail injector assembly, precisely sprays into inlet manifold, participates in burning into internal combustion engine.Using stream
Meter measures the amounts of hydrogen for mixing burning, while check valve A can prevent internal combustion engine tempering from causing danger to system pipeline.When system is stopped
When only working, remaining air pressure is higher in pipe, opens pneumatic operated valve B, into decompression tank, removal system mesohigh hydrogen stores up air venting
It deposits and security risk.When the internal combustion engine is started again, pneumatic operated valve C is opened, a small amount of hydrogen in tank is depressurized and enters inlet manifold, with sky
Enter combustion in IC engine after gas mixing, while check valve B can prevent internal combustion engine tempering from causing danger to system pipeline.
