Online oil condition monitoring of four stroke engine

In present day practice, the engine oil change period is decided by offline laboratory investigation by the Original Equipment Manufacturers and oil companies. Generally the oil change period is fixed with reference to standard testing conditions. Usually lubricant oil changing is done without knowing the actual condition of the oil as per vehicle manufacturer recommendations. Generally oil changing period recommended by the manufacturer is either at a particular period of time or at a particular Kilo-meter. Due to this, lubricant oils are changed much before using full life of them. This paper finds solution to this problem. It will enable us to use the lubrication oil to its full life. In this, a temperature sensor gives data for actual temperature of oil to the processing unit, which converts temperature signals into viscosity units. The viscosity of oil is displayed in the display unit. Thus we can easily find out the condition of lubricating oil, which is that it helps to change the lubricating oil at correct time. Also this exact time of oil replacement in an engine, avoids wastage of lubricating property of oil and reduces cost of maintenance. This project displays the condition of lubricating oil to the vehicle user. By extended oil changing periods, the overall lubrication oil consumption may be reduced. It gives positive impact on the economy of any country with reduction of oil imports.
