Description
Technical field
The invention belongs to automotive engineering, and relating generally to a kind of is the automobile fuel gas supply system of fuel with the combustion gas.
Background technique
Along with the rising significantly of oil fuel growing tensions such as the gasoline of petrochemicals, diesel oil and shortage and price thereof, be that the automobile of fuel obtains fast development with the combustion gas in recent years, become the new trend of development of automobile.But, since existing be the problem that design exists on the automobile fuel gas supply system of fuel with the combustion gas, make to get into the unadjustable and control of air inlet in the gas engine.In actual motion, combustion gas and air mixing ratio are unreasonable, uncontrollable, and the after-combustion of combustion gas entering motor is insufficient, incomplete, and not only exhaust emissions causes environmental pollution, and causes the loss and waste of combustion gas, and user cost improves.In addition, in the gas engine running, the tempering detonation is the easiest generation, modal operation troubles; Gently then cause the supply air line joint to come off; Air filter housing, conduit failure, heavy then cause the damage of assembly such as expensive closure, Security is relatively poor.
Summary of the invention
The purpose of the invention is exactly the problem that exists to above-mentioned existing technology; Design provides a kind of adjustable automobile fuel gas supply system with the tempering flameproof apparatus of air quantity that has, and reaches environmental protection and energy saving, prevents the tempering detonation, improves the gas engine operational security, reduces the purpose of user cost.
The purpose of the invention be achieved in that a kind of have air quantity adjustable with the automobile fuel gas supply system tempering flameproof apparatus comprise gas box, air-strainer and gas engine; The two ends of air filtering organ pipe are communicated with air-strainer and gas engine respectively; It is inner that the combustion gas mouth is fitted in the air filtering organ pipe; The two ends of gas supply pipe are communicated with gas box and combustion gas mouth respectively, equipped vaporizer on gas supply pipe, the adjustable and tempering explosion-proof valve of equipped air quantity on the air filtering organ pipe; Described air quantity is adjustable and tempering explosion-proof valve position between air-strainer and combustion gas mouth; Be provided with tempering explosion-proof relief hole on the valve chest of and tempering explosion-proof valve adjustable in air quantity, this tempering explosion-proof relief hole is adjustable in air quantity with the spool of tempering explosion-proof valve and combustion gas mouth between the position, adjustable and tempering explosion-proof valve inner chamber and atmosphere with air quantity; The explosion-proof band of elasticity is sleeved on the valve chest outside, and the airtight covering in tempering explosion-proof relief hole is contained.
The invention has realized that the air quantity that gets in the gas engine is controllable; Guaranteed that air and combustion gas mixing ratio are scientific and reasonable; And the damage that can eliminate and avoid combustion gas tempering detonation that motor is caused; Have simple and reasonable for structure, air quantity regulation and control simple and convenient, that fuel gas buring is fully complete, energy-conservation is remarkable with environment protection effect, use and maintenance cost is cheap, safe, advantage of wide range of application, can be applying of gas combustion automobile and play promoting effect energetically.

Embodiment
Below in conjunction with accompanying drawing the invention embodiment is described in detail.A kind of have air quantity adjustable with the automobile fuel gas supply system tempering flameproof apparatus comprise gas box 1, air-strainer 8 and gas engine 5; The two ends of air filtering organ pipe 6 are communicated with air-strainer 8 and gas engine 5 respectively; Combustion gas mouth 4 is fitted in air filtering organ pipe 6 inside; The two ends of gas supply pipe 2 are communicated with gas box 1 and combustion gas mouth 4 respectively, equipped vaporizer 3 on gas supply pipe 2, the adjustable and tempering explosion-proof valve 7 of equipped air quantity on air filtering organ pipe 6; Described air quantity is adjustable and tempering explosion-proof valve 7 position between air-strainer 8 and combustion gas mouth 4; Be provided with tempering explosion-proof relief hole 11 on the valve chest 9 of and tempering explosion-proof valve 7 adjustable in air quantity, this tempering explosion-proof relief hole 11 is adjustable in air quantity with the spool of tempering explosion-proof valve 7 and combustion gas mouth 4 between the position, adjustable and tempering explosion-proof valve 7 inner chambers and atmosphere with air quantity; Elasticity is explosion-proof is with 10 to be sleeved on valve chest 9 outsides, and the 11 airtight coverings of tempering explosion-proof relief hole are contained.
During the air feed operation; Combustion gas gets in the air filtering organ pipe 6 through gas supply pipe 2, vaporizer 3, combustion gas mouth 4 from gas box 1; Air through air-strainer 8, air quantity is adjustable gets in the air filtering organ pipes 6 with tempering explosion-proof valve 7 and after the combustion gas mixing, send into gas engine 5 internal combustion operations.The change air quantity is adjustable and the aperture of tempering explosion-proof valve 7; The air quantity that adjusting gets in the air filtering organ pipe 6 from air-strainer 8; Can accurately regulate the mixed proportion of air and combustion gas, realize the abundant perfect combustion of combustion gas, both practice thrift gas energy; Reduced user cost, alleviated the pollution of exhaust emissions again environment.When gas engine generation tempering in service detonation; Gas-air body pressure in the air filtering organ pipe 6 raise rapidly, stop at the adjustable spool with tempering explosion-proof valve 7 of air quantity to cooperate time, and it is explosion-proof with 10 airtight covering containing that elasticity is washed in the tempered explosion-proof relief of pressure mixed gas hole 11 open; In air filtering organ pipe 6, discharge fast; Avoid the generation of mechanical damage accident, thereafter, elasticity is explosion-proof is with 10 resiliences; Rapidly tempering explosion-proof relief hole 11 is sealed to cover once more and contain, gas engine 5 continues normal operation.
