What is PDE Unit Injector about?
The document describes the operation of a PDE unit injector, detailing four phases: filling, waste, injection, and pressure reduction. During the filling phase, fuel is drawn into the plunger cylinder, while in the waste phase, fuel flows back to the feed channel. The injection phase involves the solenoid valve closing to build pressure for fuel injection, which is controlled by the Engine Electronic Control Unit, followed by a pressure reduction phase where the valve opens again to allow fuel flow.
