Abstract (en)
[origin: EP0999355A2] A fuel injector apparatus includes an electromagnetic fuel injector having a housing and a magnetic circuit in the housing. The magnetic circuit including an electromagnetic coil constructed and arranged to operate at a nominal voltage to open the fuel injector. The nominal voltage is substantially less that a supply voltage. Circuit structure is electrically coupled with the coil and is constructed and arranged to step-down the supply voltage to be substantially the nominal voltage at the coil. <IMAGE>
