Subject: RE:Injectors tick by CFI-EFI on 2008/1/29 0:36:06 An injector is a solenoid. Just like the solenoid in your starter. When the ECM energizes the injector the coil of wire along with it's movable ferris core becomes an electromagnet, and pulls the core out of it's at rest position. That ferris core is the pintle. It is opened as described by the ECM and allowed to seat under spring pressure when the coil is de-energized. Noise is a natural byproduct of the pintle seating. RACE ON!!! |
