Abstract

The large sample data classification statistics of exhaust pollutants test data from 57,997 in-use vehicles were conducted under acceleration simulation mode conditions, two-speed idle conditions and free acceleration conditions. Aiming at the test data obtained from acceleration simulation mode, the implementation date of different stages national standards for vehicle emissions was regarded as the service life interval classification rules. Emission limits provided by the inistry of Environmental Protection of the People’s Republic of China are referred to analyze the unqualified rate, the changing trends and group deterioration trends systematically. The determining principles and requirements on exhaust pollutants limits when formulating a new local standard in China are described. Standard revision process through determining the revision object of exhaust pollutants limits and predicting unqualified rate based on the pre-revised limits and post-revised limits is proposed. The research can not only extract valuable information from large data for accurately determining the characteristics of high-emission vehicles, but help environmental management department to formulate relevant vehicles exhaust pollutants limits standard and management decisions.
