AIR INTAKE DEVICE, SENSOR UNIT, TWO-WHEELED VEHICLE, AND INTAKE AIR TEMPERATURE DETECTION METHOD

摘要

An intake air temperature sensor and a pressure sensor are compactly installed in an air intake device. An intake air temperature sensor (22) is installed in a flow path (11) of a throttle body (10), on more on the upstream side than a throttle shaft (13). Also, the intake air temperature sensor (22) is positioned forward of the throttle shaft (13), at a position where the temperature sensor (22) is not in contact with a throttle valve (12). The entrance of a pressure-introducing path (15) for introducing pressure into a pressure sensor (23) is positioned on the downstream side of a first half segment of the throttle valve (12) that is pivoted to the upstream side when the throttle valve (12) is pivoted in the open direction. One of two screws for attaching the sensor unit (20) to the throttle body (10) is positioned on the upstream side of the half segment section. The other screw is positioned on the down stream side of the other half segment section. Further, a measured value of an intake air temperature is corrected to a measured value of an intake air temperature at the vicinity of an air cleaner.
