The Exhaust Emission from Passenger Cars using Portable Emission Measurement System
The paper presents the results of on-road exhaust emission tests of Passenger Cars fitted with diesel engines.Under such conditions the authors could determine the actual vehicle emissions.The tests were performed on a road portion of a hundred kilometers or so – these tests provide information on the on-road emissions and are a basis for their ecological evaluation.For the measurement of the exhaust emissions the authors used a Portable Exhaust Emissions System.The obtained data were used to calculate the relations that characterize the influence of the dynamic engine parameters on the exhaust emissions.These properties were taken into account indirectly using the whole range of speeds and accelerations of the vehicle for the preparation of the matrices of the emissions rate.The used data were averaged within individual speed and acceleration ranges thus obtaining the characteristics of the share of operation in individual ranges and the characteristics of the emission matrices of the individual emission components.The above results served for defining of the emission level indicator of the vehicles that can be used for classification of vehicle fleet in terms of their emission level).
