THERMAL ANALYSIS OF THREE CYLINDER ENGINE HEADAND PERFORMANCE OPTIMISATION 

Abstract

In the present work thermal analysis of thermal barrier coated compression ignition engine is done the heat transfer through thecylinder head with and without ceramic insulation is analysed. two different insulation coating materials are used. Heat transfer is analyzedand the amount of coolant required is optimized to save the heat lost and power consumed. Series of experimentations and computationalsoftware are used for the thermal analysis of the L.H.R. (low heat rejection) engine. The rapid advances in computer and simulationtechnology make it possible to model complex geometrical shapes, assign load cases and analyze associated deformations and materialbehavior. The results show that optimization of the cooling system of the conventional and L.H.R. engine saves the extra heat lost in coolingand is available for improving the engine performance.The internal combustion engine is a rich source of examples of almost everyconceivable type of heat transfer. There are a wide range of temperatures and heat fluxes in the various components of the internalcombustion engine. Internal combustion engines come in many sizes, from small model airplane engines with a 0.25 " (6 mm) bore andstroke to large stationary engines with a 12" (300 mm).About 25 % of the air/fuel mixture energy is converted to work, and the remaining75% must be transferred from the engine to the environment. The heat transfer paths are many, and include many different modes of heattransfer.In this module, we will discuss the heat transfer processes in the engine components, then consider the engine parameters andvariables which affect the heat transfer processes. Maximum amount of heat is transferred through the cylinder head. In this project wehave taken efforts to analyze the heat transfer through the cylinder head of three cylinder S.I. engine. CAE is extensively used for simulation.Heat transfer is analyzed for different rates of coolant flow and a optimized coolant flow rate is suggested.Keywords: Cylinder Head, Thermal Analysis, Heat Transfer.
