Enhancement of Heat Transfer Rate Using Transient Thermal Analysis for Actual and Proposed Design of the Single Cylinder Air Cooled Four Stroke Spark Ignition Engine

Heat transfer from the IC engine take place in all modes like conduction, convection & radiation. About 25 % of the fuel energy is converted into useful work and the remaining 75% to be transferred from the engine to the environment. The calculation of engine heat transfer is very difficult because the engine geometry is complex and there are periodic air and fuel flow during the entire cycle. The main object of present work is to increase heat transfer rate from cylinder head & block of single cylinder SI engine and also provide best solution to increase heat transfer rate with optimum design of the IC engine. For that Three CAD models have been created with the help of CATIA & further Thermal analysis are performed in ANSYS 16.0. Transient thermal analyses were performed for actual as well as proposed design of IC engine one by one to optimize geometrical parameters and enhanced heat transfer rate from the same. Investigated result revel that the proposed design -2 of single cylinder four stroke IC engine has better performance and heat transfer rate from the heating zone in the IC engine.
