A cooling system for an engine transmission in a saddle type vehicle such as an all-terrain-vehicle. In one embodiment, the cooling system has an induction duct, connected to a belt case that houses a transmission, for inducting cooling air into the belt case. The system further includes a discharge duct connected to the belt case for exhausting the cooling air from the belt case, the discharge duct extending toward a rear fender of the vehicle. In addition, the system has an air exhaust aperture through which the cooling-air exits the discharge duct, the exhaust aperture located at an end of the discharge duct, the discharge duct generally forming an inverted "U" shape as viewed from a rear end of the vehicle, and the air exhaust aperture positioned so that the cooling air exiting the discharge duct does not directly strike the rear fender of the vehicle. The cooling system further has an induction box having a cooling-air induction port that allows the entrance of cooling-air into the induction box, the induction box being generally positioned in the transverse center of the vehicle, and the induction port being opened at a position near the bottom of a front fender of the vehicle.

A propulsion system for a vehicle, comprising of an internal combustion engine, a thermoelectric device in thermal communication with the engine, and a control system for controlling the engine and the thermoelectric device during a first mode, supply electrical energy to the thermoelectric device to cause the thermoelectric device to produce at least some heat, and during a second mode, operate the engine to produce at least some heat, where the thermoelectric device is operated to convert a temperature gradient at the thermoelectric device to electrical energy.

An air cleaner device for a vehicle is provided with an air cleaner body containing an air cleaner element and a snorkel connected to the air cleaner body to introduce the outside air into the air cleaner body. The snorkel extends forward of the vehicle past a side of a cylinder portion which projects upward from an engine, and a front end of the snorkel opens between right and left seats of the vehicle. With this configuration, even if the air cleaner body of the air cleaner device should be flooded, it is difficult for water to enter into the interior. Further, it is difficult for the air cleaner body to be influenced by heat, and difficult for dust to get into the air cleaner body.

In a battery cooling air intake structure, in which a trunk side lining (35) of a vehicle body side part is disposed so as to be continuous with a side part of a seat back (32) of a seat for a passenger to sit on, and a battery is cooled using, as cooling air, air within a vehicle compartment taken in via an intake port (36) provided in a front face (35a) of the trunk side lining (35), since a seat belt (38) is disposed so that at least part thereof in a non-used state overlaps the intake port (36) when viewed in the vehicle body fore-and-aft direction and a predetermined gap (b) is formed between the intake port (36a) and at least part of the seat belt (38) when viewed in the vehicle width direction, it is possible to prevent interference with the intake of cooling air due to the intake port (36) being blocked by the seat belt (38), while disposing the seat belt (38) as far toward the outside in the vehicle width direction as possible so that it does not overlap the seat back (32).

A recreational off-highway vehicle includes side-by-side passenger and driver seats held within a chassis that is approximately 50 inches wide. The seats sit low in the chassis and are covered by a roll cage. Grab handles are positioned on the sides of the passenger seat. Select large round tubing protects the vehicle, while rectangular tubing frames the portions of the vehicle beneath body panels. The vehicle is powered by an engine rearward of the seats that is connected to a transaxle. The engine and transaxle are isolation mounted together with a portion of the air intake assembly. The vehicle is suited for rough terrain travel.

An off-road vehicle includes a frame and wheels. An engine of the vehicle has a crankshaft. A transmission transmits the rotation of the crankshaft to the wheels. A housing houses a transmission mechanism of the transmission. The housing has an air inlet duct through which ambient air enters the housing and an air outlet duct through which the air leaves the housing. The air inlet duct has an inlet opening. The outlet duct has an outlet opening. The inlet and outlet openings are positioned higher than the wheels.
