ABSTRACT:
In order to supply an air-fuel mixture composed of the fuel and compressed air to a combustion chamber of an engine, an air-fuel mixture valve is opened by a valve body which is moved via the core shifted by magnetic force of the electromagnetic coil. The invention provides a method of determining the magnetic force of the electromagnetic coil on the basis of the relationship defined by Fm.gtoreq.Fv-fa, where Fm denotes axial tension depending upon the magnetic force of the electromagnetic coil, Fv denotes force necessary for opening or closing the empty air-fuel mixture valve, and fa denotes force for compressed air to open the air-fuel mixture valve. The pressure of the compressed air is used as the auxiliary force to open the air-fuel mixture valve. This allows the air-fuel mixture valve to be made more compact and reduces power consumption of the electromagnetic coil.
