LPG or Liquefied Petroleum Gas, a by-product of refined crude oil, is a gas at room temperature and pressure, and a liquid at a pressure of 2 Bar.

In automobiles it is used as a propane and butane gas mixture whose chemical and physical characteristics provide outstanding performances in terms of power, flexibility and efficient engine operation.

It burns without leaving any engine carbon deposits that lead to premature wear and extends the service life of spark-plugs, valves and pistons while helping engine oil maintain its original properties longer.

When burned, it produces less carbon and nitrogen oxides and unburned hydrocarbons than petrol or diesel oil, without generating any aromatic hydrocarbons or sulphur dioxide.

Refuelling is carried out by inserting a special nozzle into the car’s filler opening. It is possible to fill 80% of the tank.

Gas flows from the tank and, running along the high-pressure piping, passes through an on-off solenoid valve. This valve is closed when the car is running on petrol or when turned off. From the solenoid valve, the gas is fed to the reducer-vaporiser.
In the reducer-vaporiser, the L.P.G.is heated by the engine water to ensure perfect gasification, which then changes from a liquid to a gas and thus at atmospheric pressure enters a mixer unit that provides the gas to the engine according to demand.
