The electro-hydraulic injector is composed of 3 major components: The oil control, the pressure amplification, and the nozzle assembly. The injector uses 2, 48-volt at 20-amp coils to control a spool valve that directs oil flow in and out of the injector. The fuel injector has a self-extracting hold-down clamp.
