All Landi Renzo products and systems are the result of years of in-depth study and research on a technological level that have led to the registration of several patents. The numerous inventions of the Landi Renzo Research and Development Centre have resulted in an important development of LPG and CNG motor propulsion components, always integrated further into petrol systems of mechanics as well as electronics. A wide range of technologically advanced products allows the company to satisfy the requests of even the most demanding clients and the requests of the most advanced car manufacturers. The Landi Renzo systems use energy sources with a low environmental impact and therefore contribute towards the development of eco-sustainable mobility, guaranteeing energy savings and economic advantages.


Automotive device which reduces and stabilizes the natural gas pressure, in order to properly feed the engine. The three reduction stages provide stability at both high and low pressures. The pressure regulator is equipped with a pressure relief valve and a low pressure solenoid valve fitted upstream of the third stage. The necessary operating heat is provided by a connection with the engine coolant system. The engine idling gas flow is activated through the gas pipe main flow as a result of the negative pressure generated by the engine. CN04 is equipped with an electronic starting device with a built-in safety system which closes the gas solenoid valve when the engine stops.

  • Regulator type: 3 stages with electronic starting device and idling at negative pressure
  • Use: automotive (suitable for vehicles with or without catalytic converter, injection and carburettor)
  • Type of fuel: CNG (compressed natural gas)
  • Heating: Engine cooling circuit liquid
  • Test pressure: 300 bar
  • Inlet pressure: 220 bar
  • First stage adjustment pressure: 4 bar
  • Second stage adjustment pressure: 1.5 bar
  • Power supply: 12 V DC
  • High-pressure solenoid valve coil power capacity: 20W
  • Versions:CN 04: up to 100 kW





The most important features of Benzo Triana 2000 regulator are:

- Three reduction stages, allowing an excellent flow of natural gas to engine, in every working conditions.

- Internal safety valve, with over pressure protection, which release the gas in the feed circuit to prevent external leaks.


- Gas/water heat intercharger , to balance temperature losses caused by expansion phase, assuring the best performance, despite of climatic factors.

- Minimum regulation device, that assure a better operating at low speed-, in order to avoid engine stops.
