Abstract
We have developed a method by which the oil flow rate can be measured by using a hot-wire sensor that could be installed in the passages of actual engine lubricant oil. This measuring method proves to have a ±5% accuracy and a 40kHz response that enables ‘real time’ function.
Thus, observation of (1) the effect of bearing clearance, and (2) the fluctuating mechanism of the oil flow per 1 degree crank angle from the point of engine start-up to 6000r/min and full load can be achieved, and the timing and quantity of intermittent oil-jet from the oil hole in connecting rod were ascertained.
