How the system works




The LANDIRENZO OMEGAS 4.0 electronic control unit with an aluminium body, designed and built for integration with the electronics on new generation Euro 4, Euro 5 and Euro 6 vehicles, offers you the possibility of connecting to your vehicle's OBDII (On Board Diagnostic II) to:

  • acquire and monitor petrol correctors during gas operation
  • compensate for variability in the quality and composition of gas

Use Omegas 4.0 to check the petrol injector connection and conduct diagnosis of operation on individual gas injectors, and to manage partially petrol-fuelled operation, guaranteeing excellent performance in terms of quality and durability. Its PIN-outs enable the ECU for management and control of external electronic devices.




The LI10 is a single-stage positive pressure reducer for sequential LPG systems, with a safety valve, a solenoid valve and built-in filters. Its excellent heat exchange ratio makes it reliable even at the lowest temperatures. Moreover, the features of the materials used and the layout guarantee outstanding dependability on aspirated and turbo engines.




GIRS12 injector rails are designed and tested to guarantee very high performance and precision delivering fuel. Small size makes them easily adaptable to fit the engine compartment, and they are particularly strong and silent.

They guarantee very good hold even under extreme conditions with a IP6K9K connector.

Its 4 sizes makes it suitable for the requirements of engines of different levels of performance and different sizes (2-3-4 cylinders).

Square Switch


Square Switch

Square electronic control unit; functions include:

  • gas/petrol switch and indicator of fuel in use with two leds 
  • display of the quantity of gas in the tank with 5 leds.

Switch with an adjustable buzzer that sounds under the following conditions: switch back to petrol due to low pressure, switch back to petrol due to diagnosis.

Multivalve and filling point


Multivalve and filling point

The multivalve is a mechanical device required to store LPG properly inside the tank.

In compliance with European Regulations ECE 67R-01, LANDIRENZO Multivalves are equipped with a pressure relief valve, a temperature relief valve, an excess flow valve, a non-return valve and a shut-off solenoid valve.

The multivalves are extremely accurate in shutting off fuel supply automatically at 80% of the total tank capacity, as prescribed by the Regulations.

All the multivalves are set up for installation of an electronic level indicator.

The external filling point, fitted with a non-return valve, permits LPG refuelling the world over.

LPG tank


LPG tank

Landi Renzo offers various types of LPG tanks, selected based on strict safety criteria, in line with the highest standards of car manufacturers, and meeting the needs of most vehicles. Doughnut shaped tanks are housed in the place of the spare tyre. Cylindrical models, instead, are installed either in the boot or externally.

Both types of tank come in different sizes and capacities.

For safety reasons, LPG cylinders can only be filled to 80% capacity; this level is detected by the multivalve.
