The working principle of the CNG vehicle natural gas pressure reducing valve with Atiker/Tomasetto Type LPG/CNG Reducer Solenoid Coil is that there are three decompression chambers to achieve three-stage decompression. The first stage reduces the high pressure to the low pressure; the second stage adjusts the distribution; the third stage of the cng pressure reducer is controlled release.

The high-pressure compressed natural gas comes out of the gas storage cylinder, is filtered by the natural gas filter, and enters the high-pressure pressure reducer through the high-pressure solenoid valve. The opening and closing of the high-pressure solenoid valve is controlled by the ECM, and the high-pressure pressure reducer functions as a high-pressure compressed natural gas. (Working pressure 200bar-30bar) The pressure is adjusted to 7bar-9bar by heating under reduced pressure. High-pressure natural gas needs to absorb a large amount of heat due to pressure expansion during decompression. To prevent the pressure reducer from freezing, the engine coolant is taken out from the engine to the pressure reducer to heat the gas.

According to the physicochemical properties of gas, the volumetric energy density of CNG and LPG is very low in the gaseous state. In order to improve the mileage of a gas vehicle inflated, the natural gas for vehicles is generally compressed to 20 MPa and stored in a high-pressure gas cylinder, while the LPG is pressurized to about 1.6 MPa into a liquid state and stored in a cylinder. However, when the engine is working, the gas pressure is required to drop to 1~2.5KPa to enter the mixer to mix with the air and enter the cylinder. Therefore, a pressure reducer must be provided in the gas supply system. At the same time, the engine uses gas as well as fuel, and it needs to deliver fuel to the cylinder at a certain air-fuel ratio. The air-fuel ratio control of the gas supply system is also the same as that of the fuel supply system, and does not vary with the amount of fuel in the fuel tank. Since the pressure of CNG gas in the high-pressure gas cylinder changes continuously with the filling and use of the fuel, it is necessary to maintain a relatively stable air-fuel ratio control, and it is also required that the pressure reducing regulator should also ensure the gas entering the mixer regardless of the change in the pressure inside the bottle. The pressure is essentially constant to achieve a relatively stable gas to air mixing ratio control.

In CNG vehicles, the role of CNG pressure reducers is mainly to reduce pressure and voltage regulation, so it is generally called a pressure reducing regulator. The role of the pressure reducer on the LPG vehicle is mainly to evaporate the liquid petroleum gas into a gaseous state, as well as decompression and voltage regulation, so it is generally called an evaporation damper. Since a large amount of heat is absorbed during the decompression process, a water jacket for introducing engine circulating water into the pressure reducer is generally provided on the pressure reducer, and the heat exchanger is heated by the heat of the engine circulating cooling water.

Pressure reducing regulators are a key component of gas vehicles. The pressure reducing regulator can be divided into split type and combined type according to the assembly mode of the multi-stage decompression chamber; according to the control mode, it can be divided into high-pressure cut-off control type and medium-pressure cut-off control type; according to the output to the carburetor Pneumatic type can be divided into positive pressure intake and negative pressure intake.
