ABSTRACT:
A fuel injection device for a model engine capable of injecting fuel directly into a combustion chamber of the engine, to thereby insure stable feeding of fuel even under severe operational conditions. A check valve is arranged in a fuel injection passage or port to prevent backflow of fuel. Such construction permits the fuel injection device to be mounted directly on a cylinder of the engine to inject fuel directly into a combustion chamber of the engine, unlike the prior art. Also, in the present invention, pressurized air held in an air holding space may be injected together with fuel only during fuel injection, resulting in fuel being injected in the form of a fine mist-like shape.
