Effect of Material and Fin Geometry of Effectiveness of 100 CC Small Motorcycle Automobile Cylinder

Abstract

In the case of design of a small two-wheeler, designing a cylinder and its cooling system is a big deal for engineers and researchers. To have a stable combustion in case of SI engine, the temperature at any point of cylinder can’t be raised to auto ignition temperature of the fuel. Thus, the cooling system of engine must be properly designed. When designing cylinder of two-wheeler, the choice is very limited. The fins can be an important technique for engine cooling. This paper presents a comparative study of magnesium alloy and grey cast iron (GCI) alloy as probable cylinder materials and rectangular, triangular and Trapezoidal shape as fin geometry. The solid geometry of cylinder having different types of extended surface was prepared in Solidworks and imported to ANSYS for further processing. The GCI alloy found to be better than magnesium alloy and the rectangular fin profile gave the least total heat flux.
