METHOD AND DEVICE FOR DIAGNOSE OF VALVES OF AN INTERNAL COMBUSTION ENGINE

A method for diagnosis of at least one valve in at least one cylinder in a combustion engine comprising the steps, at a movement of a piston in said cylinder, of detecting movements propagating in a cylinder head of the cylinder or of parts adjacent thereto in the engine, comparing values resulting...

description A method for diagnosis of at least one valve in at least one cylinder in a combustion engine comprising the steps, at a movement of a piston in said cylinder, of detecting movements propagating in a cylinder head of the cylinder or of parts adjacent thereto in the engine, comparing values resulting from the detection step with at least one stored setpoint value, and determining the state of said at least one valve, based on the result of said comparison.
