Mathematical Model of Piston of Four Stroke Diesel Engine

This thesis work is concerned with temperature distribution and thermal stress[1] analysis in a four stroke diesel engine piston. The finite element approach is applied for the above analysis. The piston selected for the above objective is heaving diameter 195 mm. Although temperature of hot gases (Tg) and coefficient of heat transfer (h g ) between hot gases and piston top surface very cyclically, but the problem has been simplified by giving them constant values.
