Study on Energy Consumption and Emissions from Hybrid Electric City Bus under Different Driving Cycles

Article Preview

Abstract:

A hybrid electric city bus was tested to explore its energy consumption and emissions under Chinese City Bus Cycle (CCBC) and World Transient Vehicle Cycle (WTVC). Energy consumption and emission factors under two cycles were compared. Contribution rates of different driving models to gaseous emissions were studied. Results showed, energy consumption and CO factor under CCBC were higher than those under WTVC, THC and NOx factors under CCBC were lower. Contribution rates of accelerating models to THC and NOx were 3~4 times higher than those of idle models, contribution rates of CO were more than ten times of that of idle models.
