A Mathematical and Experimental analysis of degradation of lubricating oil in four stroke Motorbikes

Abstract

This paper presents a mathematical and experimental analysis of degradation of lubricating
oil used in four-stroke motor bikes. For mathematical analysis, Debye equation have been
related to the dielectric constant and temperature of lubricating oil samples of four stroke
motorbikes The instrumentation system used for experimentation consists of (i) a coaxial
cylindrical capacitor and a LM35 IC as sensors (ii) A ATmega 32 based microcontroller
system for sampling, processing and display of signal. The coaxial cylindrical capacitive
sensor and LM35 are used to provide the measure of dielectric constant and temperature of a
lubricating oil sample.
