A Simple and Accurate Experimental Method for Measurement of Engine Oil Consumption

Abstract — Oil consumption in today’s internal combustion engines has become a major concern. There are various methods available today in industry to measure engine oil consumption. However, the slow process of oil consumption during engine operation presents a big challenge in a quick and accurate measurement. This acts as a big hindrance for oil consumption studies. Existing measurement methods are very expensive, require huge resources for setup, time consuming, not portable and involve various sources of errors. In this paper, first a review of the various techniques available for petrol and diesel engines along with their advantages and disadvantages are presented. Then a simple and a reliable method which bridges the gap between cost, time and accuracy between existing measurement techniques is proposed. Results obtained from the present method are compared with existing method and the error is quantified. It was found the drain and measure method consistently over predicts the oil consumption by about 20%. Keywords—Engine, Oil consumption, Experimental method, Drain and weigh, Pressur
