With the new developments in electronics, use of electronic sensors is becoming more common in today's vehicles. Oil level monitoring using electronic level sensor is one of them. In this paper, an algorithm developed for Ecotorq heavy duty diesel engines is presented and software measures developed to overcome typical application challenges are described. The sensor used on the engine has a damping tube in which the oil flows through a very small hole to dampen the oil flow. The sensing method is ultrasonic sensing. Direct calculation of total amount of oil from oil level is not possible anytime, since a portion of the oil circulated in the engine varies with engine speed and some part of the oil trapped in the different regions of the engine changes with road conditions. Additionally, lubrication oil is not still while the engine and/or vehicle is running due to effect of crankshaft oil spill and vehicle movements.
