摘要：
Information storage element 102 and transmitter-receiver 103 are molded in resin connector part 101 of fuel injection valve 100 which projects outside of the engine by molding. The precise control of an injection amount is enabled by using directly the characteristic of injection amount stored in information storage element 102, and obtaining the width of the injection command pulse corresponding to the injection amount instruction value. Thereby, the minimum injection amount which is the minimum value of the fuel supply amount which can be controlled is reduced.
