Title:
【発明の名称】オイル劣化モニタ方法及びその装置
Document Type and Number:
Japanese Patent JPS6037895
Kind Code:
B2
Abstract:
A method and apparatus for monitoring the degradation of oil, particularly crankcase oil. A first sensor includes creep material positioned under constant stress in thermal contact with the oil to act as an analogue computer as it changes its length in response to temperature and the time at that temperature to register the degradation of oil due to the oil's oxidation. In addition, a second sensor registers the contamination of the oil by adding the number of times the oil is heated but not heated to a high enough predetermined temperature to disperse the water, acids and sludge which contaminate the oil. When the combination of these outputs reach a predetermined limit, a signal is provided.
