What you need to know if you want to buy a CNG car

The gas filling station fills the compressed natural gas into the gas cylinder through the gas filling valve to 20MPa. When natural gas is used as fuel, the manual shut-off valve is opened, and the oil-gas fuel conversion electric switch installed in the cab is turned to the "gas" position. At this time, the natural gas solenoid valve is opened and the gasoline solenoid valve is closed. The high pressure of 20MPa in the gas cylinder The natural gas enters the pressure reducing regulator through the high-pressure pipeline to be decompressed, and then enters the mixer through the low-pressure pipeline and power valve, and is mixed with the air entering through the air filter, and enters the engine cylinder through the carburetor channel for combustion. The pressure reducing regulator is matched with the mixer to produce different vacuum degrees according to the different working conditions of the engine, automatically adjust the air supply of the pressure reducing regulator, and make the natural gas and air evenly mixed to meet the use of the engine under different working conditions Claim. The power valve is a device that adjusts the cross-sectional area of ​​a natural gas pipeline, which can adjust the air-fuel ratio of the mixture to achieve the best air-fuel ratio.
A gasoline solenoid valve is installed in the oil circuit, and the remaining parts remain unchanged. When using gasoline as fuel, the driver turns the oil-gas fuel switch to the "oil" position. At this time, the natural gas solenoid valve is closed and the gasoline solenoid valve is opened. The gasoline enters the carburetor through the gasoline solenoid valve and is sucked into the cylinder for combustion. The fuel switch has three positions. When it is turned to the neutral position, both the oil and gas solenoid valves are closed. This function is specially designed to burn out the remaining gasoline in the carburetor room when switching from gasoline to natural gas to avoid occurrence The phenomenon of mixed combustion of oil and gas.
