The 2Fuel Dual Fuel System
2Fuel’s dual fuel system is designed to retrofit conventional diesel engines, allowing them to run on a blend of diesel fuel and alternative fuels like natural gas or propane. What sets 2Fuel apart is its ability to maintain OEM performance specifications throughout the high load cycle, delivering high “end of day diesel dilution percentages” without compromising torque or mileage efficiency.
Technological Achievements
2Fuel Technologies has earned an esteemed position in the industry through its remarkable achievements. They were the pioneers in attaining CARB certification for all engine families up to 650 HP, setting a significant industry benchmark. Notably, they are the sole dual fuel system with “OEM” EPA certification, making them the trusted choice for engine manufacturers. Furthermore, 2Fuel stands as the first and only dual fuel system to be embraced in Tier 1 OEM production, underscoring their unwavering dedication to quality and innovation.
How 2Fuel Works
2Fuel operates as a Diesel Dual-Fuel (DDF) system, reducing diesel fuel consumption while consistently maintaining torque and horsepower. Mode 1, which blends diesel with an alternative fuel, offers both environmental and cost-saving benefits.
The 2Fuel ECU communicates with the OEM Controller through CANBUS, ensuring precise fuel ratios by both the alternative fuel and diesel fuel injectors while monitoring OEM sensors and parameters.
