【正文】 ic product constantly upgrading electric car, open class in mature technology and perfected, that drive more safe, convenient and flexible, fortable. Now, the electric car from ordinary consumers distance is still very far away, only a few people in bandwagon. Electric cars with traditional to pete in the market, the car will was electric cars and intelligent car replaced. This is the question that day after timing will e. ABS, GPS, and various new 4WD 4WS, electronic products and the modern era, excellent performance auto tacit understanding is tiein, bring us unparalleled precision driving fort and safety of driving.First, the development of natural gas vehicle Reduce pollution to protect the environment, many countries have issued a series of government regulations and the introduction of a number of incentive policies to promote the development of gas vehicle, such as the development of more stringent vehicle emission standards, in the natural gas supply, car purchase taxes and fees, equipment supply, gas station construction grant funds, tax incentives. or the purchase of alternative fuel vehicles and the construction of stations in detail the provisions of the tax relief, but also enacted a tax cut that the use of natural gas and natural gas panies exempt from motor vehicle fuel sales tax. There are more than 40 states in accordance with the policy of the federal government, law, drawn up on the mandatory state and encourage the use of clean fuel CNG vehicles, such as policies and measures to promote the CNG filling station development and construction of motor vehicles. At present, more than 40 countries around the world have a gas car, mainly in the rich natural gas resources in Italy, New Zealand, Argentina, Brazil and other countries and stricter environmental regulations the United States, Japan and other countries.Second, natural gas vehicle (CNG) fuel and other environmental and economic benefits pared Compressed natural gas vehicles:20MPa pressed natural gas in the car to pressed natural gas cylinders in use by the supply of internal bustion engine after the pressure reducer.To CNG fuel for vehicles pared with gasoline has the following advantages: l, reduce pollution and improve the atmospheric environment: natural gas is a clean energy, with a high calorific value, high efficiency, pollution, etc., the parison is totally burned, not carbon deposition, CO, NOx and particulate emissions than gasoline, significantly reduced exhaust pollution. Motor vehicle exhaust is the major source of urban air pollution, one of which is carbon monoxide harmful ingredients (C0), hydrocarbons (HC), nitric oxide (N0) and nitrogen dioxide (NO2) and so on. According to the data, the use of gas as a motor fuel and gasoline as fuel can reduce emissions pared to 90% CO, 90% S02, 72% HC, 39% NOx, 24% CO2, nondust emissions, to improve the urban environment has a significant role in . A typical diesel engine and gasoline engine emissions and gas machine is shown in table l.2, CNG vehicle for a higher securityCompared with gasoline, pressed natural gas is a relatively safe fuel.(1) natural gas explosion limit is 5% higher than gasoline (lower explosion limit for the l%) high, methane ignition for 645 ℃, ignition than gasoline high 218 ℃, pared to not ignite. Low density of methane, the relative density of about , resulting in leakage of gas will soon be distributed in the air, in the case of the natural environment it is difficult to form a hot bustion conditions, once the pressed natural gas from the tank or pipe leaks, leak immediately surrounding the formation of lowtemperature zone
