Comparative Analysis of Four Cylinder Engine Camshaft Material

Abstract

One of the main concerns of engineers in the field of internal combustion engines is to extend the service life of the components. Also, automotive manufacturer continually increase power train parameters, e.g. the output power and torque together with weight reduction, but this often leads to higher noise and vibration. The aim of this paper is to suggesting a better material for camshaft by comprising 2 different materials such as Grey C.I. and SAE 52100 on the basis of natural frequency, stress and deflection, wear and friction, bending strength, so it minimize vibration problem and increase service life of camshaft. From the frequency, stress and deflection obtained it is observed that the material SAE52100 gives highest natural frequency, less stress and deflection, high bending strengths than currently used material (Grey C.I.). But it is observed that specific wear rate and coefficient of friction of SAE 52100 and Grey C.I .same in all conditions, which is does not adversely affect on fuel economy. So the SAE 52100 material is most suitable material for camshaft amongst the selected materials for analysis.
