FUEL FUSION is an alternative, dual fuel system for Diesel engines, that uses LPG or CNG. The system reduces injection of Diesel fuel and in its place injects a precise dose of gas.

Diesel is injected traditionally into the combustion chambers of the engine, while gas is injected into the air intake manifold before or past the turbo compressor by two injectors.

Injecting gas allows almost complete combustion of Diesel, which is practically impossible in a regular Diesel engine. Diesel engines burn most of the injected diesel, but there is always a part that is converted to exhaust gas. These exhaust gases include, among others, carbon monoxide, hydrocarbons and carcinogenic solid particles.

The more efficient combustion of Diesel also has a positive effect on the engine’s power and torque, and at the same time has no negative impact on its life. Driving on a dual fuel power supply is a solution that brings financial and ecological benefits, and at the same time there’s no negative influence on the safe and trouble-free operation of the vehicle.

LPG and CNG in a Diesel engine is an additional fuel. In contrast to gas systems in gasoline engines gas doesn’t fully replace Diesel. Gas that is added to the fuel mixture becomes a combustion catalyst and contributes to a more efficient use of Diesel fuel.

The share of gas in the mixture depends primarily on its type. LPG share in the mix can range from 30% to 45%. However, for CNG, its share can range anywhere from 50% do 80%.

Save on fuel costs 10% or more

Thanks to partial replacement of expensive Diesel by much cheaper gas, driving a vehicle equipped with FUEL FUSION brings savings of minimum 10% on the current fuel costs.

The savings that a vehicle equipped with FUEL FUSION can bring depend on the difference in gas and Diesel prices, as well as the distances that the vehicle travels, engine capacity and Diesel consumption. The larger the consumption and distances, the greater the savings and faster return on investment.

Principles of operation

Gas is supplied from the tank through the pressure reducer (CNG) or vaporator (LPG) and is injected into the air intake either before or past the Turbocharger. Gas is dosed by injectors controlled by the FUEL FUSION electronic control unit, the heart of the system, that adjusts the work of the entire system based on information obtained from the vehicle’s  CAN and its own sensors. Information from the vehicle and the system’s ECU are continuously recorded in the internal memory of Fuel Fusion, from where it can be retrieved via a USB cable. This data can be used to generate fuel consumption reports for both gas and Diesel.

From the driver’s point of view the FUEL FUSION system is almost maintenance free, the driver has only a switch at his disposal, that indicates the approximate level of gas in the tank, while the system switches on and off automatically.

Installing FUEL FUSION does not require modifications to the original engine construction, the system is fully automated and independent. It allows adjustments to fulfill the vehicles’s individual needs. Its operation is troule-free and brings financial benefits in the form of reduced maintenance costs.

FUEL FUSION is the only system, that allows you to obtain fuel consumption reports and gives you an insight into working parameters of the system and the vehicle. The data is retrieved from the vehicle’s CAN and the system’s sensors. All data is continuously recorded in the system’s internal memory and can be downloaded via USB.  You can analyse this data to see the various system functions and parameters or generate a fuel consumption report that includes:

  • Gas consumption
  • Diesel consumption
  • Time in Dual Fuel mode

To generate a report for a vehicle equipped with FUEL FUSION you must download a log file directly from the ECU via USB and drag and drop this file into the box on the report page.
