CONDITION SENSOR FOR A FUEL INJECTOR.

摘要

The motion of a control rod in a fuel injector can be detected by an electrical sensor mounted in the fuel injector housing. The sensor includes an electrical probe, insulated from the injector housing, and having a tip located to be contacted by a shoulder on the control rod when the rod moves from the port-closed position to the port-open position. The electrical sense can be used for diagnostic purposes.
