Methods, systems, and vehicles that control the temperature of a device included in the vehicle are presented herein. The temperature of the device is controlled by ventilating the device with drivetrain air, such as transmission cooling air. In some embodiments, the device is at a greater temperature than the drivetrain air, which cools the device. In other embodiments, the device is at a lesser temperature than the drivetrain air, which heats the device. The drivetrain air is provided to the device through an exhaust duct coupled to the vehicle's transmission. The drivetrain exhaust air is preferably circulated by the transmission. The transmission may be a continuously variable transmission. The device may be an oxygen sensor that is coupled to an engine exhaust pipe. The oxygen sensor is thermally coupled to the engine exhaust and the engine exhaust pipe, which are at greater temperatures than the transmission exhaust air.
A system for cooling a device secured to a portion of a combustion exhaust pipe included in a vehicle having a forward end and a rearward end with a longitudinal axis from the forward end to the rearward end, the system comprising:
A vehicle having a longitudinal axis from front to back and having an internal combustion engine to provide motive force to drive the vehicle, the engine including an combustion exhaust pipe having an upstream end and a downstream end with a temperature-sensitive device secured to a portion of the combustion exhaust pipe at a longitudinal and lateral position in the vehicle and along the combustion exhaust pipe between the engine and a combustion exhaust pipe exit, the vehicle also including a continuously variable transmission (CVT) as part of a drivetrain for the vehicle, the CVT being driven by the engine, the CVT further comprising:
A vehicle comprising:
