To improve the performance of engines using electronically controlled gasoline injection, the fuel control range must be increased and the injection precision must be improved. This report describes the injection characteristics (fuel quantity vs input pulse width) of the previously developed up-stream-swirl-type injector. Fuel quantity of this injector tends to increase in the small injection area because of the remaining non-swirled fuel. In order to extend the effective fuel control range, it is necessary to linearize this little injection area. It became clear that to reduce the amount of bump and jump using lightweight valve assembly and decrease of the quantity of the remaining non-swirled fuel have significant effects.
