Abstract
To achieve improved cooling in a power unit, a first fan is coupled with an end of a crankshaft of an internal combustion engine to cool at least a cylinder of the internal combustion engine, and a second fan is coupled with another end of the crankshaft to cool at least the cylinder. The cylinder is cooled by the air supplied from the first fan and the second fan.
