Abstract
An engine includes a cylinder portion under which a crankshaft portion is arranged. A transmission box is arranged at one side of the crankshaft portion and includes a continuously variable transmission system arranged therein. The transmission box includes a cooling air inlet opening and a cooling air outlet opening. A cooling air intake tube is arranged on the cooling air inlet opening. The cooling air intake tube includes a cooling air ingress port. An air collection box is arranged on the cooling air ingress port. The cooling air intake tube includes a curved section posterior to the cooling air ingress port and the curved section includes a riser section. This helps ensure cleanliness of the external fresh cold air entering the air collection box and guided into the cooling air intake tube to prevent external water and dust from entering the transmission box to cause damage to the continuously variable transmission system.
