| Abstract: | This paper is a study on CNG engine.It introduces the present condition of CNG engine firstly.Then it researches the compress ignition system.There are three gluts witch have different connecting passage diameter between the main and auxiliary chamber in the experiment.The experiment shows: gas mixture temperature,connecting passage diameter between the main and auxiliary chamber and injection time are important influence factors.Higher intake temperature and bigger connecting passage diameter make the engine have good starting ability,but smaller diameter can put out more power.Injection time influence the combustion status. |

| Keywords: | CNG engine compress ignition gas mixture temperature injection timing |
