The engine ….. uses the temperature of the engine to cool the liquid LPG. The evaporator converts this gas into LPG at high pressure.
There are two types, electronic and vacuum.
The electronic type has the regulator and carburetor running together. Even though the gas line may be open, the electrovalve stops the flow of fuel to the engine.
Vacuum regulators are pneumatic. They use lower pressure. The regulator can only be activated when the engine runs (vacuum in manifold).
The LPG Regulator: What is its role?
LPG Regulator: Features
- The entire body and cover are made entirely of composite aluminum material.
- The water heating chamber and the gas chamber are separated by the provision of the water/gas storage conditions.
- ECE-R67.01 standards state that the materials used for LPG use in diaphragms, gaskets and springs are suitable.
- The test pressure is 67.5 bars
- An electrovalve completes the gas flow closure at the output of 1st stage.
- The adjustment and idle line are two different things.
Installation of LPG Regulator
It should be mounted vertically at the closest point to both the carburetor & vehicle. After the LPG has passed through the valve, it is mounted through the copper pipes to the regulator’s inlet.
To send the vaporized gases from the regulator to the engine through a mixer gap, a braided hose coated in metal is used. The regulator receives hot engine water through clamps by mounting pressure resistant water hoses to its outlet and inlet. This hot water allows liquid LPG to be sent to the engine through an electromagnetic valve within the regulator.
The valve can be operated with 12 Volt electrical power. It receives commands from the selector switch through a cable. A reservoir holds oil, slag and other foreign particles. LPG that comes from the gas valve is liquid forms turns into gas in regulator. Oil and particles are not converted to gas because of the specific gravity difference are stored in the slag chamber. The drain plug should be removed from this chamber at 15,000 to 20,000 km.
Depending on the LPG quality, the diaphragm should always be replaced every 50,000 to 100,000 km.
