Effect of Cylinder Block Fin Geometry on Heat Transfer Rate of Air-Cooled 4 Stroke SI Engine – A Review

In case of automobile the fuel saving is the prime important with minimum emission and best performance. The phenomenon by which heat transfer takes place through engine fins must frequently be improved for these reasons. Air-cooling used to reduced weight and simple in construction of engine cylinder block. So,air-cooled engine build heat, the cooling fins permit the wind and air to move the heat away from the engine. Low rate of heat transfer during cooling fins is the main problem in this type of cooling. Fins are extended surface which are used to cool various structures via the process of convection. Generally heat transfer by fins is basically limited by the design of the system. But still it may be enhanced by modifying certain design parameters of the fins The main of aim of this work is to study various researches done in past to improve heat transfer rate of cooling fins by changing cylinder block fin geometry, climate situation and material.
