 DESCRIPTION OF THE "CONVENTIONAL LPG" KIT FOR A CARBURETTOR VEHICLEThe LPG in the liquid state reaches the regulator-vaporiser ( 1 ) through the LPG solenoid valve ( 2 ), which is only open when the vehicle is running on gas. The LPG is vaporised inside the regulator and its pressure is reduced. From the regulator - vaporizer the LPG in the gaseous state is in-taken by the engine through the mixer ( 3 ), which is specific for each individual vehicle and fitted upstream from the throttle, allowing the gas to mix perfectly with the air to create an even mix. Considering that the kit is standard, a maximum pressure register ( 4 ) is to be fitted on the connection hose between the regulator-vaporiser and the mixer which, together with the adjustment screw on the regulator, enables the installer to perfectly set and adjust the system. When the vehicle is running on gas the flow of petrol is intercepted by a solenoid valve ( 5 ) fitted between the mechanical fuel supply pump and the carburettor. The choice of the fuel on which the vehicle is to run (LPG or Petrol) is completely up to the driver who can choose the fuel by operating the switch ( 6 ) fitted in a handy position inside the vehicle compartment. This switch can also be equipped with a fuel indicator. |

DESCRIPTION OF THE "CONVENTIONAL LPG" KIT FOR A NON-CATALYTIC INJECTION VEHICLEThe LPG in the liquid state is sent from the cylinder to the regulator-vaporiser ( 1 ) through the LPG solenoid valve ( 2 ) which is only open when the vehicle is running on gas. The LPG is vaporised inside the regulator and its pressure is reduced. From the regulator – vaporizer the LPG in the gaseous state is in-taken by the engine through the mixer ( 3 ), fitted upstream from the throttle allowing the gas to mix perfectly with the air to create an even mix. Considering that the kit is standard, a maximum pressure register ( 4 ) is to be fitted on the connection hose between theregulator-vaporiser and the mixer which, together with the adjustment screw on the regulator, enables the installer to perfectly set and adjust the system. When the vehicle is running on gas the flow of petrol is intercepted by an electric relay or electronic emulator ( 5 ), which stops the original petrol electro-injectors. The relays or emulators are specific according to the type of petrol system. The choice of the fuel on which the vehicle is to run (LPG or Petrol) is completely up to the driver who can choose the fuel by operating the switch ( 6 ) fitted in a handy position inside the vehicle compartment. This switch can also be equipped with a fuel indicator. | |||||||||||||||||||||||||||||||||||

The LPG is vaporised inside the regulator and its pressure is reduced. From the regulator – vaporizer the LPG in the gaseous state is in-taken by the engine through the mixer ( 3 ), fitted upstream from the throttle allowing the gas to mix perfectly with the air to create an even mix. Considering that the vehicles are catalyst ones, a fuel adjustment control system must be installed in the system. This system is equipped with an electronic control unit ( 7 ), which commands an actuator ( 4 ), fitted on the connection hose between the regulator-vaporiser and the mixer, ensuring the perfect stoichiometric ratio of the mix, based on the lambda signal sent to the Gas electronic control unit by the original petrol lambda probe. When the vehicle is running on gas the flow of petrol is intercepted by an electric relay or electronic emulator ( 5 ), which stops the original petrol electro-injectors. The relays or emulators are specific according to the type of petrol system. The choice of the fuel on which the vehicle is to run (LPG or Petrol) is completely up to the driver who can choose the fuel by operating the switch ( 6 ) fitted in a handy position inside the vehicle compartment and which is already equipped with a fuel indicator. | |||||||||||||||||||||||||||||||||||
