Air filter, engine air intake system and vehicle

The invention relates to an air filter, an engine air intake system and a vehicle. During the air intake process, two air intake pipelines directly communicate with a first air intake passage and a second air intake passage on the air filter; airflows in the two air intake pipelines enter the air filter through the first air intake passage and the second air intake passage and are mixed in the airfilter; the air intake system structural pipelines eliminate an air mixing chamber, the structure is simple, the occupied space in an engine cabin is small, and the adaptability is high; in addition,the airflows in the two air intake passages enter a shell and interact to eliminate the air intake noise and reduce the air intake pressure; the two air intake passages simultaneously intake the air,so that on one hand, the divergence ratio of the air filter is increased and the noise eliminating capacity is improved, and on the other hand, the air intake efficiency is improved and the air intake capacity of the air filte
