Internal combustion engine is known as one of greatest invention, plays key player in the production and living of the mankind, but with
And come energy crisis and environmental pollution allow people headache endlessly.Various countries just actively research and develop new energy internal combustion engine, hydrogen loading at present
Internal combustion engine is wherein important developing direction.Hydrogen belongs to clean energy resource, from a wealth of sources, energy-efficient, has been widely used；By
In the special physicochemical property of hydrogen, safety, applicability are that hydrogen loading fuel combustion hydrogen gas feed system is in need of consideration important
Project.This system uses security control, decompression protection and anti-backfire, and the safety measures such as air backflow resistent also ensure simultaneously
The applicability of whole system.
Prior art disadvantage:
(1) hydrogen loading fuel combustion still belongs to starting design and experimental stage, matched hydrogen gas feed system technology at present
Basic blank；
(2) high pressure hydrogen feed system anti-backfire, pipeline decompression protection device are not perfect；
(3) traditional solar term doorway hydrogen loading mode, each cylinder hydrogen distribution is uneven, and mixed effect and combustion efficiency are bad；
(4) IC engine blend-burning amounts of hydrogen can not be precisely controlled.
Summary of the invention:
The purpose of the utility model is to provide a kind of hydrogen loading fuel combustion hydrogen gas feed systems, and this system is using safety control
System, decompression protection and anti-backfire, the safety measures such as air backflow resistent, while also ensuring the applicability of whole system.
Above-mentioned purpose is realized by following technical scheme:
A kind of hydrogen loading fuel combustion hydrogen gas feed system, composition includes: hydrogen generating system, heat exchanger and combustion gas filtering
Device, the air taking port of the hydrogen generating system are connect with the air inlet of the heat exchanger, the gas outlet of the heat exchanger
It is connect with the combustion gas filter, the combustion gas filter is connect with the pneumatic operated valve A, the pneumatic operated valve A and steady
Pressure valve connection, the pressure maintaining valve are connect with flowmeter, and the flowmeter is connect with check valve A, the check valve A and combustion
The connection of gas rail injector assembly.
The hydrogen loading fuel combustion hydrogen gas feed system, the heat exchanger are connect with the air inlet of pneumatic operated valve B,
The gas outlet of the pneumatic operated valve B is connect with check valve, and high-temperature hydrogen is generated in the hydrogen generating system, when high-temperature hydrogen is passed through
Become room temperature hydrogen when the described heat exchanger.
The utility model has the beneficial effects that
1. the utility model structure is simple, perfect in shape and function, manufacturing cost is low, using pneumatic operated valve instead of solenoid valve control,
It avoids the generation electric spark in hydrogen pipeline from causing danger, while passing through pressure maintaining valve and control nozzle injection pulse width, precisely adjusting
Hydrogen loading tolerance and spray regime good mixing effect.
2. the utility model internal combustion engine does not work, this system is closed, survival gas drains into ambient atmosphere in pipeline, arranges
In addition to high pressure hydrogen storage remaining in system and security risk.
3. the utility model pressure relief pipe installs check valve, avoids air from entering hydrogen feed pipe road, cause danger, simultaneously
Check valve is installed on hydrogen feed pipe road, prevents internal combustion engine tempering from causing danger to system pipeline.
4. the utility model is that when the engine operates, hydrogen generating system generates high-temperature hydrogen, become normal through over-heat-exchanger
Warm hydrogen, after pneumatic operated valve A is opened, room temperature hydrogen filters impurity that may be present by combustion gas filter, protects member in pipeline
Part, hydrogen pass through room temperature pressure stabilizing after pressure maintaining valve, import combustion gas rail injector assembly, precisely spray into internal combustion engine and participate in burning.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, air venting is into ambient atmosphere, removal system mesohigh hydrogen
Security risk is stored, while check valve B can enter hydrogen pipeline to avoid outside air, cause danger.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model.
In figure: 1, hydrogen generating system, 2, heat exchanger, 3, combustion gas filter, 4, pneumatic operated valve A, 5, pressure maintaining valve, 6, flowmeter,
