Abstract
A cathodic protection system has electrodes disposed in a coolant passage of an engine filled with a conductive coolant. The electrodes are electrically insulated from the engine. A power supply device provides for a protective electric current to form from the electrodes to the engine through the coolant. The cathodic protection system reduces engine manufacturing and maintenance costs and provides an anticorrosive effect without increasing the size of the engine.
