摘要： A laminated structure fuel swirl element is employed, in which a strong swirl force flow is imparted to the fuel at a remote side against an injection hole and on the other hand, at a near side of the fuel injection hole, a weak swirl force is imparted to the fuel. A complex solid cone spray can be obtained, such a spray has a superior a dispersion characteristic by attracting small diameter droplets which are generated at an outer peripheral portion of the spray through a spray which is generated at a vicinity of a central portion of the spray and has a large velocity. In the spray characteristics in an electromagnetic system fuel injector of a direct injection gasoline engine, a complex solid cone spray can be obtained, as a result a good ignitability of the engine can be obtained by a spray having a small spreading angle by making strong an inertia force and a discharge amount of the unburned gas components of the combustion can be reduced by a spray having a short reaching distance and a large spreading angle by making weak the inertia force.

摘要： The target peak current value, where a current value is reduced in conformity to a drop in the voltage of a battery 18 is stored in target peak current storage unit 68. ON-signals are sent from current control circuit 56 to power transistor 50 in response to the injection command pulse coming from engine controller 58 so that current is applied to coil 20. Then, the current flowing to coil 20 is detected by the current detecting resistor 52. Comparator 62 compares this detected current and the target peak current value read from the target peak current storage unit 68 conforming to the voltage of battery 18. If agreement is found between these two values, OFF-signals are sent to power transistor 50 from current control circuit 56 in response to the switching command coming from comparator 62. Then, On/Off signals to effect holding of the coil 20 are sent from current control circuit 56 to power transistor 50. The linearity of the injection volume despite changes in battery voltage can be maintained.
