Research on CO Pollution Control of Motor Vehicle Exhaust

Carbon monoxide (CO) is harmful to our health, and even causes death. The main source of CO is automobile exhaust. Therefore, this article determines that CO is the emission factor, and finally the evaluation model is established. The model provides an important basis for the highway construction project design, traffic management, environmental pollution control, energy saving, environmental evaluation and so on. Compared with the traditional method that calculates the road traffic volume through the air emissions model, according to the total amount of air pollution control, this paper builds the emission diffusion model, which calculates the road traffic volume by road exhaust density. First of all, this paper measures CO emissions by testing 435 multifunction detectors from Shanghai typical roads, and compares the results with the national standard control. According to the standard in automobile exhaust emissions, the extreme values of the traffic volume over the road are calculated. Finally, the model’s reasonableness and accuracy are validated through case study. The results from case analysis show that the evaluation model is of great practical significance.
