| Abstract: | Research has been done in vehicle emission measurement and analysis technology for dilution constant volume sample system of vehicle exhaust gas.The delay of emission gas transportation and analysis for components in gas are dealt with.The definition and calculating equation for dilution factor(DF) are given.Based on measuring data during test period,calculation model of transit emissions feature of vehicle and vehicle fuel consumption calculating equation based on carbon-balance are deduced.VTCL—VETS(Vehicle Emission Test System) host controlling system of vehicle emission test are introduced,and its application sample are given. |
