LPG vehicles are vehicles that use LPG as fuel. When liquefied petroleum gas burns, liquid liquefied petroleum gas is pressed out of the container by its own evaporation pressure and enters the regulator through high-pressure pipeline, filter and solenoid valve. The pressure is reduced, vaporized and adjusted in the regulator, and then mixed with air through the mixer to form combustible mixture which enters the engine.

Liquefied petroleum gas (LPG) is a mixture of hydrocarbons with 3 or 4 carbon atoms, such as propane (C3H8), propylene (C3H6), butane (C4H 10) and butene (C4H 10), which can be divided into oil and gas fields and refinery LPG. Liquefied petroleum gas (LPG) in oil refinery cannot be directly used as automobile fuel because it contains a lot of olefins. Liquefied petroleum gas in oil and gas fields is mainly composed of propane and butane, which can be directly used as automobile fuel.

Liquefied petroleum gas (LPG) is a gaseous hydrocarbon mixture at normal temperature and pressure, which is heavier than air and has higher octane number. It has the advantages of uniform mixing, full combustion, no carbon deposition and no dilution of lubricating oil, which can prolong the service life of the engine, with large gas carrying capacity and long driving mileage.

LPG single fuel engine car: The fuel supply system of the engine is specially designed for burning LPG fuel, and its structure ensures the effective use of fuel.

Dual-fuel (gasoline and LPG) vehicles: At present, most LPG vehicles are dual-fuel vehicles, which have reached the stage of commercialization. Without two fuel supply systems, the engine can switch from one fuel to another with a selector switch, but it is not allowed to mix the two fuels at the same time.
