日常生活中，汽车天然气改装现象越来越多，人们也更加关注这方面的知识
In daily life, cars gas phenomenon more and more, people also pay more attention to this aspect of knowledge
最简单的天燃气系统由一只仿真器和一套减压阀组成， 减压阀出来后的管子通过一个节流阀与原车空气隔相连，通过调节减压阀和节流阀，车子就可以动起来。 天然气改装原理很简单， 一个仿真器，来用模拟喷油嘴， 也就4只2W的电阻， 让ECU认为喷没嘴的信号是完整的。
The simplest natural gas system is composed of a simulator and a pressure reducing valve, pressure reducing valve after pipe through a throttle valve connected with the original car air isolation, by adjusting the pressure reducing valve and throttle, the car can move. Natural gas conversion principle is very simple, a simulator, nozzle to use simulation, also just 4 2 w resistor, let the ECU you don't think jet mouth signal is complete.
汽车天然气改装发动机内的温度不够，燃油和润滑油的温度都不够，所以在冷启动时应该多喷油以满足动力性的要求.火花塞的间隙越大，点火能量就越小。低温时燃油雾化不好，燃油需要更高的点火能量，车子长时间使用，火花塞的点火间隙容易变大，导致点火能量下降，从而影响动力性，使车子发生抖动。
Cars gas within the engine temperature is not enough, the temperature of the fuel oil and lubricating oil is not enough, when cold start so should have more fuel injection to meet the requirements of dynamic performance. The spark plug gap, the greater the ignition energy. When low temperature fuel atomization is bad, need higher fuel ignition energy, the car use for a long time, the ignition of spark plug gap easily get bigger, led to the decrease of the ignition energy, thus affecting performance, make the car jitter.
但济南汽车油改气要是想运行得较理想，还需要有点火提前节调节器，然后由一套电控系统控制的一个脉动喷射阀（或步进电机）组成。通常为了不至于让车子回到汽油状态油耗变大，还接有一个氧传感器仿真器。脉动喷射阀的喷射时间受ECU控制。
But jinan car oil to gas if you want to run more ideal, also need to have a regulator, ignition advance section and is controlled by a set of electric control system of a pulse jet valve (or step motor). Usually not to let the car back to the state of gasoline fuel consumption, also has an oxygen sensor simulator. Pulse jet valve discharge time is controlled by ECU.
