LPG gas single fuel engine system comprising: an engine control module, the ignition control module, ignition coil, spark plugs, an electronic throttle, the mixer, the main fuel control valve (FTV valve), the idling fuel control valve, evaporator pressure regulator, high pressure solenoid valves, control valve and wastegate surge valve. In addition, also include various sensors and wiring harness. The entire system controls the engine and vehicle performance, emissions and safety. The current capacity using a single source of gaseous fuel as an engine Weifang the gas engine, the main LNG (liquefied natural gas) engines, CNG (compressed natural gas) engines and LPG (liquefied petroleum gas) engine of three. Compared with the same gas engine displacement diesel engine, gas engine power is quite price quotes, obvious environmental advantages of gas engine manufacturer, easier to achieve national IV, V emission country. And the current production technology mature, production process equipment and diesel engines can be common. Under the premise of maintaining the spread of oil and gas, fuel economy significantly. But the gas engine also has some shortcomings, such as short driving range, fueling a long time, too, such as filling stations construction investment.
