汽油机的空燃比是1：14.7相信很多干汽修行业的都清楚，现在推出新式汽车油改气，一方面是为了节约资源另一方面就是为了减少汽车尾气对环境的污染，那么汽车汽车改装天然气（油改气）后应根据实际情况对车的用气量做出调整。
Gasoline engine air-fuel ratio is 1:14. 7 believe many dry automobile industry are clear, now the new car oil to gas, on the one hand is to save resources, on the other hand is to reduce automobile exhaust pollution to the environment, so cars car gas oil (gas) should be according to actual circumstances, gas in the car after adjust.
汽车油改气怠速旋钮调试：向左或向右调整怠速旋钮，待发动机怠速平稳后，在附近微调找到转速最高点后，再适当调大怠速旋钮，直到发动机转速降为800转左右。怠速调整完毕。
Debugging: car oil to gas idle speed knob to the left or right to adjust the idle speed knob, momentum motivation after idle speed smoothly, after fine-tuning found near speed high, augmenting the idle speed knob appropriately again, until the engine droop for about 800 turns. Idle speed adjustment.
汽车油改气的注意事项：如怠速调整完毕后，出现下列几种情况：
Matters needing attention of car oil to gas, such as idle speed adjustment has been completed, the following several ways:
1.排空档熄火的原因：，怠速旋钮调整位置不当，动力阀调整位置不当 ，混合器喉径配合不当
Gap stall reason: 1. The row, idle speed adjustment knob, inappropriate position of power valve adjustment, inappropriate position of mixer throat diameter mismatch
2.动力不足的原因：，动力阀开度太小，混合器喉径配合不当（燃烧过浓或过稀），循环水未接（致使一级阀芯处结冰堵塞天然气）
: 2. Underpowered reasons, the dynamic valve opening is too small, mixer throat diameter mismatch (burning too thick or too thin), circulating water don't answer (the level of valve core ice jams natural gas)
3.放炮的原因：怠速旋钮调整太松 ，动力阀开度太大，混合器喉径太小
3. The cause of the shooting, idle speed adjustment knob is too loose, the dynamic valve opening is too big, mixer throat diameter is too small
4.发动机怠速不稳的原因：，怠速旋钮调整位置不当 ，动力阀调整位置不 ，混合器喉径配合不当 。
4. Reason: the engine idle speed instability, idle speed adjustment knob, inappropriate position of dynamic adjustment valve position, mixer throat diameter mismatch.
5.回火的原因：，怠速旋钮调整太紧 ，动力阀开度太小 ，混合器喉径太大
5. Reason: tempering, idle speed adjustment knob is too tight, the dynamic valve opening is too small, mixer throat diameter is too big
6.其他原因：有可能是发动机自身气缸压力过低，各气缸工作情况偏差，气门间隙问题，点火系统问题。因油和气燃点不同，遇此情况有可能烧油正常而烧气不正常，以上原因请检修发动机。
6. Other factors: cylinder pressure is likely to be the engine itself is too low, each cylinder work deviation, problem of valve clearance and ignition system. For oil and gas ignition point, when the situation is likely to burn oil normal and burned gas abnormal, the above reasons, please repair the engine.
济南汽车油改气指出因同类车型有可能出现发动机吸力不一样，厂家所配混合器的喉径一般是经验数据，但不一定适合每一辆车，遇吸力特殊的车，可以适当更换混合器的喉径。混合器的喉径大小、动力阀开度、怠速旋钮的松紧共三个参数是调试的关键,此三个参数配合好，可以让所有的发动机在高转速和低专速完全燃烧，这就是我们要达到的最佳调试效果，完全燃烧能使油改气汽车最省气和动力性最好。
Jinan car oil to gas pointed out that because of the similar models possible engine suction, manufacturer is the throat diameter of mixer is generally empirical data, but not necessarily suitable for every car, meet suction special car, can replace the throat area of mixer appropriately. Throat diameter size of mixer, power valve opening, the tightness of idle speed knob, a total of three parameters is the key to debug, the three parameters with good, can let all the engine combustion in high speed and low speed, this is what we want to achieve the best effect of debugging, complete combustion can save gas and oil to gas car most power performance is best.
