Gasoline direct fuel injection systems offer significant reduction in fuel consumption and emissions compared with current port fuel injection systems. To become a widely adopted standard in fuel injection systems, injector manufacturers have battled to overcome problems caused by the much higher fuel pressure in direct injection systems. Delphi Automotive has developed a lower cost, innovative new injector that significantly reduces noise levels, performance variation, emissions and fuel consumption.
Delphi has achieved these gains through new technologies, including a decoupled armature and pintle assembly, a stamped metal injector tip, and powerful flux gate electromagnetics. This breakthrough injector is installed on Hyundai vehicles and will accelerate the adoption rate of gasoline direct injection at automakers worldwide.
