Abstract

A fuel Metering system for a two-cycle internal combustion engine comprises an induction pipe through which air is drawn and mixes with fuel entering through an injection orifice in the pipe. A diaphragm pump has a diaphragm separating first and second pump chambers, the first chamber being in communication with the crankcase of the engine and the second chamber being connected through a one-way valve to a fuel tank and through a pressure valve to the injection orifice in the induction pipe. The one-way valve and the pressure valve are adapted to permit fuel to pass from the tank to the pump and from the pump to the injection orifice, respectively. The system provides a simple method of metering fuel which is less complex than conventional carburettor and fuel injection systems and also eliminates the use of a float chamber which renders the system particularly suited to mobile applications such as chain saws, etc.
