Fits in Current Engine Architecture
Scalable for 30 to 1,000-bar fuel systems
The injector’s efficient magnetic design provides excellent feedback for unprecedented fuel control. It significantly reduces over-fueling during the injection-opening event by employing a unique armature solution.
In addition, its variable valve body diameter allows for tighter packaging
and the power group’s modular construction enables fast and efficient changeovers between various connector designs.
