Oxygen and fuel gas regulators usually have two stages: The first stage of the regulator releases the gas at a constant pressure from the cylinder despite the pressure in the cylinder becoming less as the gas is released. The second stage of the regulator controls the pressure reduction from the intermediate pressure to low pressure.

A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.
Regulator: regulates the gas flow according to the requirement of the engine. Vaporizer: vaporizes the liquid form LPG into gas form by using the hot coolant circulation of the engine. In European style systems, the size and shape of the venturi of the carburettor is designed to match the converter. In USA style systems, the air valve and ...

LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG, vaporised and at atmospheric pressure, has a higher calorific value (46 MJ/m 3 equivalent to 12.8 kWh/m 3 ) than natural gas (methane) (38 MJ/m 3 equivalent to 10.6 kWh/m 3 ), which means that LPG cannot simply be substituted for ...

Gas cylinders may be grouped by several characteristics, such as construction method, material, pressure group, class of contents, transportability, and re-usability. [2] The size of a pressurised gas container that may be classed as a gas cylinder is typically 0.5 litres to 150 litres.
