Abstract
The invention relates to a compressed natural gas vehicle which comprises a gas storage cylinder, a pressure regulating valve, a mixer and an engine, wherein compressed natural gas is stored in the gas storage cylinder which is connected with the mixer through the pressure regulating valve, a gas outlet of the mixer is connected with a gas inlet of the engine, the pressure of the compressed natural gas in the gas storage cylinder is 20-25MPa, the pressure of the compressed natural gas after the pressure is reduced by adopting the pressure regulating valve is 0.15MPa, the pure natural gas is mixed with air in the mixer, and the mixed gas enters the engine. The compressed natural gas vehicle has the advantages that the fuel cost is saved, the transportation cost is reduced, the compressed natural gas is higher than fuel in safety, the compressed natural gas has better explosion resistance, the compressed natural gas vehicle has a better environment friendly effect, the maintenance period of the vehicle engine can be prolonged by adopting the compressed natural gas for combustion, the service life of the engine is prolonged, the maintenance cost is lowered, and is reduced by about 50 percent in comparison with that when the common fuel is used.
Description
Technical field
The present invention relates to a kind of new-energy automobile, particularly a kind of automobile with compressed natural gas.
Background technique
According to statistics, the crude oil in China import accounts for half of total amount consumed; Expect the year two thousand twenty, Motor Vehicle crude oil consumption amount will account for 86% of total amount, and the external interdependency of crude oil will reach 80%.In pollution of atmosphere, 20 Urban Chinas the most serious of global pollution have accounted for 16; Guangzhou Motor Vehicle (comprising motorcycle) quantity only is 1/10 of Los Angeles and Tokyo, but the discharge capacity of pollutant is suitable with the total amount in these two cities.
Gas-fueled vehicles are energy-conservation, the low pollution of generally acknowledging in the world at present, economic, safe novel substitute fuel automobile.Nearly two during the last ten years, world's Natural Gas Demand sustained, stable growth, and Average growth rate remains on 2%, and it will be increased to 30% at the proportion that the world energy sources composition gathers to estimate the year two thousand twenty.The China's natural gas automobile is applied Demonstration, the city increases to 19 by 12, in fact carries out the provinces and cities of this work far more than 19.
Rock gas is a kind of energy of cleaning, and its main component is methane, and main resultant is carbon dioxide and water after the burning.Compare with gasoline automobile, CO descends approximately 90% in its exhaust emissions, and it is about 50% that HC descends, and it is about 30% that NOX descends, and it is about 70% that SO2 descends, and it is about 23% that CO2 descends, and it is about 40% that Particulate Emission descends, and plumbous compound can reduce by 100%.
Summary of the invention
Goal of the invention: the automobile with compressed natural gas that the purpose of this invention is to provide a kind of safety and environmental protection.
Technological scheme: a kind of automobile with compressed natural gas, comprise gas storage cylinder, pressure regulator valve, mixer and motor, described compressed natural gas is stored in the gas storage cylinder, and gas storage cylinder is connected with mixer by pressure regulator valve, and the mixer air outlet is connected with engine intake; The pressure of compressed natural gas is 20 to 25Mpa in the described gas storage cylinder, compressed natural gas through the pressure regulator valve step-down after the pressure of rock gas be 0.15Mpa, pure rock gas mixes with air in mixer, mixed gas carries out motor.
Working principle: compressed natural gas, general normal pressure can be preserved at normal temperatures at 20Mpa to 25Mpa, and preservation equipment does not need to do the heat insulation processing of insulation.After will being kept in the gas storage cylinder compressed natural gas gas and storing, pressure regulation is delivered in the mixer to the gas of 0.15MPa through pressure regulator valve, mixes with air at this, enters the motor car engine work by combustion.Still use the plug ignition in the ignition system of former petrol engine.The compression ratio of former petrol engine does not change, and originally the structure of motor is substantially constant, just adds in addition air cylinder, reduction valve and the corresponding switch of rock gas.
In order to improve the boat ability of holding of vehicle, described gas storage cylinder comprises at least two single steel cylinders that are interconnected, and is connected with mixer through pressure regulator valve by one of them steel cylinder.
In order to improve the boat ability of holding of vehicle, described gas storage cylinder comprises at least two single steel cylinders, and described steel cylinder is respectively equipped with pressure regulator valve and is connected with mixer.
Beneficial effect: 1, fuel saving expense, reduce cost of transportation; 2, more safe than fuel oil; The compressed natural gas spontaneous ignition temperature is 732 ℃, and the gasoline spontaneous ignition temperature is 232 to 482 ℃.The proportion of the relative air of rock gas only is 0.6 to 0.7 simultaneously.In case leak, can in air, spread rapidly, be difficult for assembling out of doors reaching explosion limit.Compressed natural gas is non-carcinogenic, nontoxic, non-corrosive simultaneously.Overweight large-scale combustion and explosive accident do not occur.From domestic experience with the more than ten years compressed natural gas, gas-fueled vehicles are more safer than fuel-engined vehicle; 3, compressed natural gas fuel knock performance is good, and the knock rating of compressed natural gas is equivalent to the octane value of gasoline about 130, and the octane number that uses at present is the highest only about 96, so compressed natural gas does not need additive as automotive fuel.The like plumbous antiknock agent that waits; 4, automobile with compressed natural gas has good environment protection effect, uses the compressed natural gas replacing gasoline as automotive fuel, can make the CO discharge amount reduce 97%, CH compound minimizing, 72%, NO compound minimizing, 39%, CO2 minimizing, 24%, SO2 and reduce 90%, and noise reduces 40%.And the toxic substance of the cancers processed such as CNG is not leaded, benzene.All compressed natural gass are preferred fuels that the Automobile Transportation industry solves environmental issue; 5, use the service cycle that compressed natural gas can prolong motor car engine, motor car engine is take compressed natural gas as fuel, and motor operates steadily, and noise is low.Carbon distribution can be reduced without heavy hydrocarbon, the major repair of vehicle reason time can be prolonged more than 20%, oil change cycle stretch-out to 1.5 ten thousand Km.Improved engine life, maintenance expenses reduces, than the maintenance expenses of using conventional fuel saving about 50%.
