The Magneti Marelli TetraFuel system provides within a single ECU an extension of the fuel management capability to four different fuel types, thus enabling a vehicle to be filled, according to the owner’s choice, with gasoline, any ethanol/gasoline blend, pure alcohol or CNG (Compressed Natural Gas).

The TetraFuel technology reduces drastically the conversion/retrofit cost for a change to CNG.

 

Through the TetraFuel technology the gas management capability is available as original equipment which eliminates a series of electric and electronic separate devices, necessary for today’s adaptation

 

The TetraFuel system uses a Magneti Marelli custom-chip which, within one single ECU, can control the optimized use of both gasoline and gas.

The TetraFuel approach chooses automatically the fuel option for each driving situation to reach the optimal compromise between performance and fuel economy.

 

Furthermore, the Magneti Marelli TetraFuel system, which is based on a fully integrated low-pressure approach and not on an adaptation, as current retrofit systems are instead, decreases significantly polluting emissions and in particular the GHG-emission (Green House Gas – i.e. CO2).

The Magneti Marelli Tetrafuel system was 100% developed in Brazil, but the technology can be exported to other part of the world where there is a strong environmental pressure to reduce overall vehicle polluting emission levels, as in North America, China and Europe.
