An oil cooling jacket 3 is formed on at least a portion of the engine E, and an oil cooler 4 is attached to the cylinder 1 at a position closer to the cylinder 1 than the oil pan 5 of the engine E. The oil cooler 4 and the oil return path 10 are connected to each other so that oil can circulate in this order, an air cooling air path 8 is formed in at least a part of the cylinder 1 of the engine E, and a cooling fan 40 is attached to the engine E. In the combined air-cooling/oil-cooling forced cooling system for the engine configured to allow the cooling air generated in step 40 to pass through the air cooling air passage 8 and the oil cooler 4, the oil coming out of the oil cooler 4 is passed through the oil pan 5.
This combined air-cooling/oil-cooling forced cooling system for an engine is characterized in that an oil return path 10 for guiding the oil to the cylinder 1 runs facing the air cooling air path 8 of the cylinder 1. 2. In the combined air-cooling/oil-cooling forced cooling system for an engine according to claim 1, the oil return path 10 is run in the atmosphere outside the cylinder 1 instead of facing the air cooling air path 8, A combined air-cooling/oil-cooling type forced cooling system for an engine, characterized in that a heat radiation fin 20 is provided in a passage 10 so as to protrude into the atmosphere. 3. In the combined air-cooling/oil-cooling forced cooling system for an engine according to claim 1 or 2, oil is supplied to the oil pan 5 of the engine E through the pump 24, the oil cooling jacket 3, the oil cooler 4, and the oil return path 10 in this order. Instead of a configuration in which the oil pan 5 is connected to allow circulation, a pump 24, an oil cooler 4, and
A combined air-cooling/oil-cooling forced cooling system for an engine, characterized in that the oil-cooling jacket 3 in the cylinder head 2 and the oil return path 10 are connected to each other in order to enable oil circulation.
