Electronic Control Unit (ECU)

The 2Fuel ECU is a 32bit, 68 pin controller specifically designed for the 2Fuel system. This control meets or exceeds the stringent SAE specifications for Tier 1 automotive electronics.

The 2Fuel ECU maintains high-speed, two-way communication, with the OEM Controller and adjusts the diesel and alternative fuel flow rates, in real-time, to insure there are no over or under fueling conditions anywhere in the engine operational RPM and load ranges due to fuel overlap.

This superior two-way communication, through CANBUS, allows 2Fuel to continue blending fuels throughout the complete full load, high torque curve and maintain the OEM specified performance while blending, leading to the highest possible “End of Day Dilution” attainable.

Injection System

As diesel fuel energy flow is reduced by the 2Fuel ECU the alternative fuel injectors introduce the alternative fuel on an “energy for energy basis”, by accurately measuring an equal amount of alternative fuel to replace the displaced diesel energy. This control feature allows for higher fuel substitution rates and stable engine operation (no hunting) in high transient load cycling.

In this method, injectors are fitted to a common fuel block, the fuel is discharged into a “mixer pin” fitted in the air stream just ahead of the inlet to the intake manifold.

The advantage of this method of fuel metering is a more precise fuel metering, faster fuel delivery response time, and a much safer environment for the engine.
