Dosing valve monitoring involves taking at least one pressure measurement with supply valve(s) closed, drawing conclusion re supply valves and/or shut-off valve faulty operation, damage and/or leakage

摘要

The method involves arranging at least one pressure sensor (8) between the supply valve or valves (4) and at least one upstream shut-off valve. It involves taking at least one pressure measurement with the supply valve(s) closed and drawing a conclusion from the measurement(s) regarding faulty operation and/or damage and/or leakage of, to or in at least one of the supply valves and/or the shut-off valve AN Independent claim is also included for the following: an arrangement for monitoring at least one fuel supply valve for an internal combustion engine.
