Abstract

In order to explore the influence of the travel dynamics parameters on the emission characteristics of the gasoline direct injection(GDI) light-duty gasoline vehicle when driving in the plateau environment, a GDI light-duty gasoline vehicle was selected as the test object, and real driving emission(RDE) tests were carried out under different driving intensity to analyze the difference in vehicle emission characteristics. The results show that the robotic process automation(RPA) value of stroke dynamics parameters and ν·a_pos[95] has a significant linear positive correlation with NOx and CO₂ emission factors, among which NOx emission has the most significant correlation with stroke dynamics parameters, while CO emission has no significant correlation with RPA. When RDE test is carried out in plateau area, NOx emission level can be judged by stroke dynamics parameters.
