Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, and particularly relates to an engine ambient temperature sensor. Background Art

[0002] The engine temperature sensor is installed at the engine water outlet, in front of the thermostat, and is used to measure the engine cooling water temperature. The engine receives the coolant temperature sensor signal as a correction signal for engine fuel injection and ignition. If there is an error in the coolant temperature detected by the coolant temperature sensor, it will affect the normal operation of the engine.

During the operation of the engine, high-frequency vibrations will occur.

Therefore, there is an urgent need for an engine ambient temperature sensor to solve the above problems. Summary of the Utility Model
