Abstract: In recent years, the state of air quality has been widely concerned and valued. Some research results show that the state of air quality in automobile is one of the very bad places, and the use of automobile has become more and more common, which puts forward more and higher requirements for the air quality in automobile. Firstly, the function and principle of negative oxygen ion technology are introduced in this paper, especially the application of negative oxygen ion technology in automobile is studied and analyzed. Secondly, it is mainly to arrange different numbers of negative oxygen ion generators in different positions in the automobile, and test the number of negative oxygen ions in the air conditioning outlet and the head area of the driver and passenger, so as to obtain the relationship between the purification effect of negative oxygen ion and the location and number of layout. Finally, the relationship between the concentration of negative oxygen ion and the air volume and mode of the air conditioner can be obtained by testing the number of negative oxygen ions in the air outlet and the driver's head area under different air volume and mode of the air conditioner. The results show that when the negative oxygen ion generator is arranged in the air outlet of the air conditioning blowing surface, it can bring better air quality purification effect in the automobile, while the use of larger air volume blowing will bring higher concentration of negative oxygen ions. The research results provide a basis for the application of negative oxygen ion technology in automobile layout, and have certain practical value.
