Gaseous and Particle Emissions Results from Light Duty Vehicle with Diesel Particle Filter 2009-01-2630
In order to measure the concentration of exhaust a mobile analyzer SEMTECH DS by SENSORS Inc and particle matter by TSI was used. In the study the results of the vehicle emission tests in the road conditions were presented as this was the only way to obtain the information on real vehicle emissions. They include information on the emissivity of the vehicles in operation and deal with the real conditions of the vehicle motion. Reliable measurement results were obtained which were verified in simulated conditions on a chassis test bed. The obtained data were used to specify the dependence characteristics for the influence of the dynamic engine properties on the exhaust emissions. The dynamic engine properties were indirectly taken into account using all the speed range and the range of acceleration calculated for the city traffic in order to prepare a matrix of emission intensity. The data used were averaged within each speed and acceleration range, which generated a characteristics of engine operation in each range and a characteristics of the emission matrices of exhaust emission.
