Research on a multi-scale emission factor dataset constructing method

Abstract

This paper proposes a multi-scale emission factor dataset constructing method. Firstly, actual road driving and pollutant emission data of heavy-duty trucks are obtained. Subsequently, a method for dividing multi-scale Bin intervals based on engine load, vehicle speed, and acceleration is proposed to establish suitable multi-scale Bin intervals for the driving characteristics of heavy-duty trucks. Finally, based on the proposed method, an emission factor dataset highlighting typical driving characteristics of heavy-duty trucks is constructed. The research findings will provide government regulatory authorities with more microscopic and multi-scale guidance on motor vehicle emissions.
