Air ventilation systems for vehicles

摘要

A straddle-seat vehicle has a frame, and connected thereto, a pair of front wheels, at least one rear wheel, a pair of footrests, an engine, a radiator connected to the engine for cooling the engine, and a cowling. The cowling encloses at least a portion of the radiator and includes an inlet in fluid communication with the portion of the radiator, a lateral outlet on a first side, and a downward outlet on a lower surface, both outlets rearward of the inlet. The inlet is adapted to direct air to enter through the portion of the radiator into the cowling. A cowling wall disposed between the inlet and one of the pair of footrests deflects air away from the pair of footrests. The lateral and downward outlets, each in fluid communication with the inlet, are adapted to direct air exiting the cowling away from the pair of footrests.
