Abstract
Abstract In line with the China 6B emissions regulation, Real Driving Emissions (RDE) have been introduced as an additional type of approval requirement. This aims to account for the influence of road profiles, ambient conditions, traffic situations, and driving behavior. However, the RDE testing procedure imposes stringent requirements, leading to high experimental costs and increased risks of failure. To address these challenges, this study utilizes a standardized random test procedure alongside the maximum 95th percentile of the v•A pos cycles to assess RDE emissions on a chassis dynamometer. The World Harmonized Light-Duty Test Cycle (WLTC) and real-world on-road driving conditions serve as comparative references. Additionally, cold start performance is evaluated across these various test cycles to provide a comprehensive analysis of emission characteristics.
