Abstract
A device for testing the lubrication of an internal combustion engine has a potentiometer circuit connected between two electrodes one in contact with the crankshaft and the other in contact with the crank case, a first voltage detector of the averaging type connected directly across the potentiometer and at least one further voltage detector of the averaging type connected to a threshold discriminator which is also connected across the potentiometer; a third averaging voltage detector may be connected to a further threshold discriminator connected across the potentiometer, this latter having a threshold set at a value different from that of the first mentioned discriminator: alternatively the first mentioned discriminator may be one having two thresholds to each of which it can be switched at will.
