Method and apparatus for supplying fuel to internal combustion engine
An apparatus is described for supplying fuel to a two-cycle internal combustion engine having a rotating crankshaft in a crank chamber, comprising an intake port provided in the engine and open to the crank chamber of the engine, a single intake passage connected at one end to the intake port and at an opposite end leading to atmosphere, and means connected to an intermediate portion of the intake passage for supplying fuel to the latter and suspending fuel supply thereto. The means consists of: a carburetor disposed in the intermediate portion of the intake passage, the carburetor having a venturi portion, a float chamber and a fuel injection nozzle connecting between the venturi portion and the float chamber; a stop valve for controlling injection of fuel into the intake passage through the fuel injection nozzle; a valve actuator operatively connected to the stop valve; and a switch means disposed in a circuit connecting the stop valve and the valve actuator, the switch means being operatively connected to the crankshaft of the engine to actuate the stop valve in accordance with revolution speed of the engine, such that the means acts to alternately admit air-fuel mixture and fresh air only, respectively, during alternate revolutions of the engine.
