Title: Device to automatically add a controlled amount of corrosion inhibitor in an engine cooling system

Abstract: Means for adding corrosion inhibitor to an engine cooling system utilizing a corrosion detector in contact with the circulating coolant and which is in an electronic circuit to activate a control valve which controls the feeding of corrosion inhibitor solution from a reservoir that is in selective communication with the coolant system. The corrosion detector may be in the form of a probe that measures solution potential or electrical resistance of a metal wire as it corrodes due to the corrosiveness of the coolant. The corrosion inhibitor reservoir is located either in communication with the line between the radiator and coolant reservoir or in a by-pass line parallel with the radiator.
