Conventional Carburetor LPG

DESCRIPTION OF CONVENTIONAL LPG KIT IN A CATALYZED INJECTION VEHICLE

LPG in its liquid state reaches the regulator-vaporiser ( 1 ) through the LPG solenoid valve ( 2 ) fitted on the regulator-vaporiser, which is only open when the vehicle is running on gas. The LPG is vaporised inside the regulator-vaporiser and its pressure is reduced. From the regulator-vaporiser the LPG in its gaseous state reaches the rail of injectors ( 3 ) at a positive pressure compared to the vacuum inside the in-take manifolds. The top chamber of the regulator is inside which a calibration spring is fitted, is connected by a tube to the in-take manifold.

There are gauged nozzles on the rail of injectors which are connected to the nozzles ( 4 ) of the in-take manifold by rubber hoses, which inject gas into the engine.

The user can choose which fuel to use (LPG or PETROL) using the change-over switch ( 7 ) fitted in a handy position inside the vehicle compartment. The change-over switch comes complete with fuel indicator .

REGULATOR FOR CARBURETOR

LPG is delivered as a liquid under high pressure to the engine. The regulator converts the liquid into gas phase and provides a delivery pressure set to the level capable of supplying the fuel the engine requires for consumption.

Most of the heat required by the LPG to turn from liquid to gas is obtained from the engine coolant.

The regulator must be installed as close to the engine as possible, below the upper level of the carburetor.

A chamber in the regulator collects oil, residue and foreign matter, which should occasionally cleaned out by means of a screw.

All pipes and hoses are constructed of material impervious to high pressure.

FILLING UNIT

A ball is installed in front of the spring which prevents the gas inside the gas-filling hose from leaking.

MULTIVALVE

The multivalve is a fixture installed in the LPG system for filling and discharging fuel and for indicating the fuel levels. It contains a buoy designed to indicate the fuel level and to prevent overfill. It also contains an inlet, an inlet nozzle, and a level indicator.

Each nozzle has a shut-off valve for safety purposes. A transmitter is installed in the said fuel level indicator to enable the driver to monitor the fuel level on the dashboard of the vehicle.

An overfill control mechanism driven by the buoy of the multivalve ensures that the fuel tank will not fill to more than 80% of capacity. In case of an accident, the multivalve automatically shuts off the LPG flow. If the pressure inside the tank increases, an automatic spring system stops the gas from flowing out.

MIXERS

The Mixer ensures that the LPG and air combine to form a homogenous mixture and sends this mixture to the engine. Ninety percent of the problems encountered by cars running on the LPG system arise from mixer failure. Therefore, all of our mixers are screw-type and must be installed properly.
