Background

The two-wheeled scooter is generally provided with a fuel injection device, and in order to control the amount of fuel output supplied to the engine, various sensors are provided in the intake system, and the amount of fuel injection is adjusted based on data provided from the sensors, wherein there is an air temperature sensor for detecting the temperature of intake air in the air cleaner.

Referring to fig. 1 and 2, the motorcycle is a conventional motorcycle and an air filter thereof. The air temperature sensor is generally arranged in two ways:

1. an air temperature sensor is mounted on the back side of the housing where the air filter forms the clean chamber. However, due to the assembly relationship, not only the clean cavity has the hidden trouble of entering dust, but also the sensor needs to have higher sealing performance and installation requirements, thereby increasing the production cost;

2. the air temperature sensor is mounted on a hood of the air filter forming a dirty chamber. Although the problem that the clean chamber enters dust and the structure is solved, when the filter is maintained and replaced by the air filter, the air temperature sensor needs to be detached firstly when the cover cap for detaching the air filter is detached, so that the air temperature sensor and the connecting line are prevented from being damaged by collision or pulling, and the maintenance of the air filter is inconvenient.

Both of the above two arrangements of the air temperature sensors have disadvantages, and therefore, the arrangement of the air temperature sensors needs to be improved.
