Green Systems makes motorcycles E85-compliant
A French start-up has found a solution to prepare existing motorcycles to run on E85 biofuel via an electronic unit that is being retrofitted. In this way, motorcycling becomes ‘greener’, as the CO2 emissions of the motorized two-wheelers are significantly reduced.
The unit will check the quality of the fuel, and adjust the engine mapping accordingly. In practice, the unit will attempt to determine the octane value of the fuel from the engine OBD data, and then adjust the timing of the ignition (later ignition timing) and injection to prevent detonation (self-ignition). A lot of engines already have a so-called ‘knock’ sensor that will adjust this automatically. For engines that don’t, this solution from Green Systems can be useful.
For bikes up to 15 years
The manufacturer indicates that the system is not only for motorcycles but also for other applications with small internal combustion engines in quads or sea scooters. Furthermore, Green Systems only offers units for vehicles that are up to 15 years old and have an electronic engine control unit which allows a remapping.
These brand- and model-specific mappings can be downloaded by the user. Updates are also offered when other fuels may come onto the market in the future.
The unit offers further electronic capabilities such as GPS tracking with telemetry capabilities and additional alarm functions where the owner can see the movement of the motorbike and possibly receive an alarm when the vehicle leaves a predetermined perimeter.
What the box can’t do?
This system will indeed optimize combustion in the engine in function of the fuel. However, more is often needed to run a vehicle on E85. After all, this fuel is corrosive and less stable over time.
For example, it contains softeners that corrode rubber and cause fuel leaks in fuel lines and membranes (fire hazard). This is especially a problem with older motorcycles (+15 years). On the other hand, aluminum and copper (often used in the intake system of engines) will also be affected by this fuel, and for the time being, the Green Systems unit cannot remedy this.
