7.5 HP Air Cooled Diesel Engine

Air-cooled engines remove engine heat by using the air that hits the engine when the bike is moving. This is why they have fins on the outside to create more surface area for the air to pass over. This cooling method is very simple, lightweight and requires no special devices.Air-cooled engines have fins extending out from the engine to pull heat away. Cool air is then forced over the fins -- typically by a fan in cars. For aircraft and motorcycles, the vehicle's speed alone moves enough cool air over the fins to keep the engine cool.Air cooling is a method of dissipating heat. It works by expanding the surface area or increasing the flow of air over the object to be cooled, or both.Air-cooled engines are fuel efficient, affordable and require lesser engine space than that of liquid cooled engines. The Maintenance costs of liquid cooled ones are higher than air-cooled engines. Liquid cooled ones are easy to operate (better riding experience) but certainty of liquid spilling out is high.
