Cold Advance Solenoid
The cold advance solenoids are designed to advance the injection timing during cold operation. The Coolant temperature switch activates the system whenever engine coolant temperature is below 95ÂºF (35ÂºC). When coolant temperature is cold, the cold advance relay is turned on by the coolant temperature switch. The cold advance relay when turned on energizes the cold advance solenoid, which in turn causes the fuel housing pressure to drop. . We can provide this solenoid according to the specification of customer requirements.
