SOLENOID CONTROL FUEL INJECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the size of a fuel injection device, having first and second valves driven by a solenoid, through reduction of the number of constituting members. SOLUTION: A fuel injection device 20 is provided in a housing 74 with first and second valves 80 and 88, and a solenoid 100 is provided with a single solenoid coil 130 and a core 104 connected to the first and second valves 80 and 88. A solenoid drive circuit is connected to a solenoid coil 130. First, a first current waveform part is fed to the solenoid coil 130 to drive the core 104 and the first valve 80 is moved without moving the second valve 88. Secondly, second current waveform part different from the first current waveform part is fed to the solenoid coil 130 to move the second valve 88.
