A recently granted patent (Publication Number: US11857906B2) discloses an innovative air cleaner designed to be installed within a vehicle body frame. The air cleaner includes an air cleaner case with an intake chamber, an intake air temperature sensor to monitor the air temperature in the chamber, an inlet tube for air intake, and an outlet tube for air exhaust. Notably, the outlet tube features an upstream portion extending into the intake chamber with a peripheral wall containing a through hole. The intake air temperature sensor is strategically positioned downstream of the outlet tube's suction port, between the through hole and the suction port in a top view.

Furthermore, the patent claims detail additional features of the air cleaner, such as the proximity of the intake air temperature sensor to the suction port, the design of an umbrella portion on the outlet tube expanding towards the suction port, and the presence of a single through hole on the peripheral wall closer to the sensor. The intake air temperature sensor is affixed to the upper wall of the air cleaner case, positioned laterally to the outlet tube in a top view, with its detection portion located above the outlet tube. These unique configurations and placements aim to enhance the efficiency and performance of the air cleaner within the vehicle body frame, ensuring optimal air intake and temperature monitoring for improved functionality.
