Design of Any Ratio Methanol/Gasoline Dual-fuel Controller

摘要

This design of dual fuel controller is out of consideration to start the engine by using methanol gasoline of different proportioning since the calorific value of methanol is lower than that of gasoline. Adjusting the low-level width of injection pulse control signal from ECU and increasing the fuel injection quantity based on the blending ratio of methanol and gasoline can make the combustion heat produced by methanol gasoline reach that produced by burning gasoline, starting the engine successfully. The controller uses remote control to adjust the fuel injection quantity and display the pulse width correcting information. The installation of the controller does not prevent vehicles from using gasoline as the fuel. The controller, convenient in installation and energy saving, is proved through experiments to be very efficient.
