AI Technical Summary
Technical Problem
In low-temperature and snowy conditions, snowflakes can easily accumulate inside the engine air filter, causing blockage of the air intake passage, which in turn can lead to engine stalling, affecting the vehicle's safety and reliability.
Method used
A heating unit is integrated into the air filter unit. The amount and condition of snow accumulation are detected by a snow volume sensor and an infrared sensor. The heating device heats the snow, melting it into liquid water, which is then discharged through a drain hole.
Benefits of technology
It effectively avoids blockage of the engine intake system caused by snow accumulation, improving the reliability and safety of the vehicle under low temperature and snowfall conditions.
