Heat dissipation is crucial to the efficiency of an Internal Combustion Engine (ICE). Especially since temperatures are known to breach the ~2300-2500 degrees Centigrade mark. Here, the role of air fins is crucial. The fin as an extended surface is used to direct the heat away from the engine back into the atmosphere. Failing which, in an uncontrolled environment, one risks burning the oil film between the moving parts. It may result in seizing the engine forcing the vehicle to enter the limp mode. With efficient cooling, the temperature can be brought down by up to 150-200 degrees Centigrade. Forming an essential component of air-cooled systems, fins can be spotted easily in two-wheelers in close proximity to the engine heads and the engine blocks.
