Engine oil contamination sensor

摘要

An engine oil contamination sensor (10) includes a first sensing electrode (24) and a second sensing electrode (26). A sensing area (22) is established between the electrodes (24, 26). The sensor (10) is oriented in an oil pan such that the sensing are (22) is completely submerged in engine oil (14). A microprocessor (32) is connected to the sensing electrodes (24, 26) and includes a program for determining whether antifreeze is dispersed in the engine oil (14). <IMAGE>
