Abstract:Motor vehicles have become an indispensable means of transportation in today's society. However, automobile exhaust has become one of the important factors affecting China's air quality and air pollution. Motor vehicle exhaust remote sensing monitoring technology has emerged as the times require, and it has become one of the effective means for efficient monitoring of automobile exhaust. This paper introduces the motor vehicle exhaust remote monitoring technology with different principles, analyzes and summarizes its advantages and disadvantages in detail, and carries out related prospects, in order to promote the development of motor vehicle exhaust remote monitoring technology.
