Description
Technical field：
The present invention relates to automobile technical field, and in particular to a kind of liquified gas automobile supplies heat-insulation system.
Background technology：
With the high speed development of China's economic, all there occurs earth-shaking change, particularly communications and transportation row in each field
Development of automobile industry in industry is even more to make rapid progress.But with the enhancing of people's environmental consciousness, energy of the country to automobile industry
Source uses the requirement for proposing more Gao Gengxin.Wherein, safe green environment-friendly high-efficiency energy-saving is convenient comfortably turns into important theme.Therewith
And what is come is that automobile with novel power arises at the historic moment.Such as solar telephone, electric automobile, gas-fueled vehicles, liquefied petroleum gas automobile
Etc. emerging in an endless stream.To reduce exhaust emissions, environment of preserving our planet contributes.
There are three kinds using the automobile of new energy on Vehicles Collected from Market：Electric automobile, gas-fueled vehicles, liquefied petroleum gas automobile.
Their advantages and defect difference are as follows：
1. electric automobile：Advantage, technology is more ripe, green, tail gas zero-emission, better economic benefit, shortcoming, continuation of the journey
Ability, charging interval length, battery are constantly decayed, and short life, change huge cost and old and useless battery treatment that battery can be brought
Environmental issue；
2. gas-fueled vehicles：Advantage, technology maturation, occupation rate of market is high, and economic benefit is obvious, and every kilometer of cost only has
Half of fuel vehicle or so, exhaust emissions is good, is the direction that government vigorously advocates, and shortcoming, endurance is very poor, and square one continues
Boat route only has 1/3rd of fuel vehicle or so, and plus due to history, gas station layouts less.Each car (is hired out
Garage's industry) to add gas twice daily, very big inconvenience is brought to routine use.
3. liquefied petroleum gas automobile：Its fuel of Vehicles Collected from Market Vehicular liquefied petroleum gas is pure propane, the car economic benefit, is continued
The factors such as boat ability are superior to natural gas automobile, through each few propane gas stations in big and medium-sized cities in the investigation whole nation, therefore give
The use of the car brings huge inconvenience, seriously limits the development of the vehicle.
It need not be incubated during the air accumulator gasification of existing liquefied petroleum gas automobile or gas-fueled vehicles, it gasifies, and the people
Needed in gasification to absorb substantial amounts of heat with the liquefied gas of liquified gas automobile, its gasification latent heat is big, and air accumulator is easily when in use
Easily freeze, so as to cause LNG gasifaction in air accumulator insufficient, influence the supply of engine.
The content of the invention：
The technical problems to be solved by the invention are to overcome existing technological deficiency, there is provided a kind of liquified gas automobile supply
Heat-insulation system.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of liquified gas automobile supplies heat-insulation system, including the air accumulator with canned valve and air outlet valve, the air outlet valve
Engine is connected to by feeder sleeve, the air accumulator is arranged in heater box, is provided with the heater box close to air accumulator
Coil pipe, coil pipe in-out end are connected to the cooling water system of engine, and the feeder sleeve passes through the sleeve pipe of inner hollow, and sleeve pipe is with supplying
The gap location of expects pipe seals, and being provided with Inlet and outlet water termination and Inlet and outlet water termination on sleeve pipe is connected to engine cool water system.
Further, the coil pipe is copper tube.
Further, the gas storage tank wall is coated with the Heat Conduction Material after 3-5mm.
Further, the Heat Conduction Material is heat conduction bonded adhesives.
Further, heater box is exposed on the air accumulator top.
Vehicular liquefied petroleum gas on Vehicles Collected from Market, its chemical composition are pure propane, and the fuel characteristic is volatile, general temperature
The lower vaporization of degree and noresidue, and civil liquefied gas its component is：Propane, butane, propylene, butylene etc., due to liquefied petroleum gas category
Refine oil byproduct, component forms that unstable (C3, C4 mixed proportion are from 1:9 to 9:1, its component is formed without unified standard, and it is vaporized
Degree, residue and the temperature change of season environment after vaporization rate, and vaporization have direct relation.Civil liquefied gas with it is automobile-used
Liquefied petroleum gas (propane), natural gas are compared, and its phosphorus content is more, calorific value is high, high compared to octane number with gasoline.
With air good mixing, it is not required to vaporize during burning, burning is complete.Therefore on engine cylinder and other parts
Carbon distribution, coking are few, and tar is not produced in combustion process, are not easy to pollute machine oil, lubricating oil will not be diluted, without often changing
Note machine oil and change spark plug, alleviate the abrasion and corrosion of engine and other parts, reduce the consumption of machine oil, engine
Smooth running, noise is small, so as to extend the service life of engine and oil exchange cycle, compared with gasoline car, and the LPG (people
With liquefied gas) major repair of vehicle mileage can improve more than 50%, and can save more than 50% maintenance cost, and service life is about
3 times of gasoline car.
Beneficial effects of the present invention are：The present invention uses civil liquefied gas as fuel, energy-conserving and environment-protective, and utilizes and start
Machine cooling water can guarantee that abundant gasification to air accumulator and feeder sleeve heating, avoid remaining in air accumulator, improve system supply energy
Power, ensure the fuel supply of engine, and exhaust emissions cleans, by the access of heating system, into the gas of engine
80 DEG C or so are heated to, its volumetric expansion expands 1.2 times, makes full combustion of gas, energy-conservation, emission reduction.
