International DT466 – ENGINE SYSTEMS – Fuel Management System – Injector Coils and Spool Valve

An OPEN coil and a CLOSE coil on the injector move the spool valve from side to side using magnetic force.
The spool has two positions:
• When the spool valve is open, oil flows into the injector from the high-pressure oil rail.
• When the spool valve is closed oil exhausts from the top of the fuel injector and drains back to the crankcase.
