The utility model discloses a fuel gas supply control device for a duel fuel engine. A supply system of another fuel is additionally arranged on an original single-fuel engine; the adoption of two types of fuel is determined a driver; and the supply of the two types of fuel is controlled in a closed-loop mode, so that a reasonable air-fuel ratio of the air to the fuel is achieved and the economy, emission and practicality of the engine are ensured. Meanwhile, an electronic throttle valve device is adopted; the defects of a mechanical accelerator can be overcome; the fuel gas supply control device for the duel fuel engine is a novel electronic throttle valve control system which has strong adaptability, high precision, small overshooting and short regulating time and has an initial position learning function and a voltage compensating function; a fault diagnosis function is added, so that the fuel gas supply control device for the duel fuel engine is safer and more efficient to use.
