Abstract：Vehicle exhaust emission is an important source of atmospheric volatile organic compounds(VOCs).Understand-ing vehicle exhaust VOCs emission characteristics and influencing factors can provide an essential theoretical basis for their pollution control.Bench test and PEMS are the major methods to carry the exhaust pollutants emission research.This review summarizes the experimental research progress of vehicle exhaust VOCs,introduces the emission characteristics of vehicle exhaust VOCs under different test methods,and compares the emission factors and component characteristics of VOCs obtained from different studies,including fuel and vehicle types,emission standards,operating conditions,starting mode,accu-mulated miles driven and fuel composition of different factors on VOCs emissions.In addition,the analysis and determination of OVOCs components,vehicle driving behavior emission reduction and biomass fuel applications will be the key research directions in the future.
