随着油价高涨，给交通运输业带来越来越大的成本压力，尤其是城市公共交通。城市公共交通有用油数量大、不能随意调整班次、车票价格不能随便浮动的特征，因此油价上涨将直接导致企业成本增加，而且这种成本无法在短时间内转嫁出去。高昂的油价不仅直接提高了用车成本，而且抬高了整个社会的物流成本。于是，寻找成品油的替代能源又一次成为人们所关注的话题。因此产生了汽车油改气。汽车油改气之后经济效益较高、社会效益好、安全性能高等优点。
With oil prices rising, increasing cost pressure to the transportation industry, especially the city public transportation. The number of features useful oil city public traffic, can not be arbitrarily adjusted flights, ticket prices can not float, thus the rise in oil prices will directly lead to increased business costs, and this cost is not in a short period of time to pass out. High oil prices not only directly increase the cost of vehicles, but also raise the entire society logistics cost. So, looking for oil alternative energy once again become a topic of concern. The automotive gas oil. Automotive gas oil after the economic benefit, social benefit is good, high safety performance etc..
汽车燃用汽油是以液体雾化后进入发动机的，在喷油嘴脏了以后雾化不好时，汽油油滴跌进发动机就会破坏机油油膜的润滑特性，增加发动机的磨损；天然气是以气体形式进入发动机的，不会破坏机油油膜的润滑特性，理论上燃用天然气可以延长发动机寿命2倍，延长大修期20万公里以上，而且发动机在整个使用过程中几乎不产生积炭。比如同样行驶30万公里的发动机，如果是烧油的，打开后会看到厚厚的积炭；但是烧气的发动机里面依然是干干净净的。
Automobile gasoline engine is entered in liquid atomized, the nozzle dirty after atomization not HERSHEY'S, lubrication characteristics of gasoline engine oil into the oil film will damage, increased engine wear; natural gas is entered in the form of gas engine, lubrication characteristics will not damage the oil film, the theory of burning natural gas can prolong the service life of the engine 2 times, prolonging the overhaul period of more than 200000 kilometers, and the engine in the whole process of using almost no carbon deposit. Such as traveling 300000 kilometers of the engine, if the burning oil, after opening, will see the thick deposits; but the burning gas engine which is still clean.
1、方便：现在的天然气都是压缩天然气。现在的储气瓶的工作压力是20MP，天然气在20MP的压力下每立方的体积为5升左右，相同热量的汽油的体积为1.15升左右，也就是说燃烧出同等热量的天然气体积是汽油的4.5倍!一般的汽车用的都是65升的气瓶，1.5排量左右的车一罐气大概能跑150到180公里！
1, convenient: the current natural gas is compressed natural gas. Gas cylinders are now working pressure is 20MP, the natural gas at a pressure of about 20MP per cubic volume of 5 liters of gasoline, the same amount of calories for a volume of 1.15 liters, that is to say the equivalent heat of combustion of natural gas is 4.5 times the size of gasoline! General motors are used in a 65 liter cylinder, 1.5 liter vehicle can probably around a gas tank run 150 to 180 km!
2、环保：有较好的社会效益。与石油燃料相比，气体燃料在制备过程中能量损失较小，对大气的有害排放污染物少。从燃料来源考虑，对环境保护是更有利的！
2, environmental protection: with better social benefit. Compared with oil fuel, gas fuel in the preparation of small energy loss process, the atmospheric emissions less pollutants. Considering from the fuel source, is more advantageous to the environmental protection!
3、安全：比较安全。CNG、LNG和LPG汽车的气瓶或气罐等都很结实可靠。天然气本身比空气轻(LPG除外)，稍有泄漏，很快就会扩散到大气中。气体燃料系统的各个部件，特别是密封部分，都经过严格的检查。因此，济南汽车油改气作为汽车燃料是比较安全的。
3, security: comparison of safety. CNG, LNG and LPG automobile cylinder or tank is very sturdy and reliable. Natural gas is lighter than air (except LPG), little leakage, soon spread to the atmosphere. Each component of fuel gas system, especially the sealing parts, all passes through the strict examination. Therefore, Ji'nan automotive gas oil as fuel for vehicles is relatively safe.
