ABSTRACT:
A method of detecting defective ignition or fuel injection system of an internal combustion engine with several cylinders and at least two spark plugs or two fuel injection devices per cylinder with separate control circuits, at least a second control circuit for the ignition or fuel injection systems is disabled so that all the spark plugs or injection devices of the at least second ignition or injection systems become inoperative, the engine running smoothness is then measured, the first system which was not disabled is identified as including the defective spark plug or injection device if the engine running smoothness was found to be affected, then the ignition or injection systems for any other spark plugs or injection devices are disabled cylinder-by-cylinder and the engine running smoothness is monitored to identify the cylinder which includes the defective spark plug or injection device.
