Influence of gear-changing behaviour on fuel use and vehicular exhaust emissions

Abstract

This study explores the influence of gear changing behaviour on vehicular exhaust emissions and fuel consumption using real drive cycles as an input. 235 different drive cycles, recorded from people participating in a survey, were imported in an emission simulation tool called VeTESS (Vehicle Transient Emissions Simulation Software). Emissions and fuel consumption were calculated with VeTESS using two different gear change assumptions (normal and aggressive). This paper reports on the differences in vehicle exhaust emissions between trips made with those two different settings.
