Relative car accessories used in the oil to gas demand higher than gasoline vehicles, jinan car oil to gas compared with gasoline, compressed natural gas itself is safe fuel.
国家颁布有严格的汽车油改气技术标准。从机器站设计、储气瓶生产、改车部件制造到安装调试等，每个环节都形成了严格的技术标准。
Countries have promulgated car oil to gas technology standards. From the machine station design, air cylinder production, change a car parts manufacturing to installation and debugging, etc., each link formed a strict technical standard.
1、燃点高：天然气燃点在650度以上，比汽油燃点427度高出223度，所以相比汽油不易点燃。
1, high flash point: gas ignition temperature above 650 degrees, 223 degrees higher than gasoline ignition point of 427 degrees, so difficult to ignite than gasoline.
2、密度低：与空气的相对密度为0.48，泄漏气体很快在空气中散发，很难形成遇火燃烧的浓度。
2, low density, the relative density of 0.48, with air leakage gas in the air soon, it is difficult to form when the concentration of the fire burning.
3、辛烷值高：可达130，比目前最好的97好汽油辛烷值高的多，抗暴性能好。
3, high octane number, can amount to 130, is better than the best 97 high gasoline octane number, good physical performance.
4、爆炸极限窄：仅5-15%，在自然环境下，形成这一条件十分困难。释放过程是一个吸热过程。当压缩天然气从容器或管路中泄漏出来时，泄孔周围会迅速形成一个低温区，是天然气燃烧困难。
4, explosion limit narrow: only 5-15%, under the natural environment, the formation of the conditions very difficult. Release process is an endothermic process. When compressed natural gas leaked from the vessel or piping, the drainage hole quickly formed around a low temperature zone, gas combustion is difficult.
储气瓶出厂前要尽享特殊检验。气瓶经常规检查后，济南汽车油改气还需要充火做火烧、爆炸、堕落、枪击等试验，合格后，方能出场使用。
Air cylinder to enjoy the special inspection before delivery. Cylinders after routine inspection, jinan car oil to gas still need to fill do fire, explosion, fire depravity, shooting and other test, after passing before use.
