“…The diesel engines have many advantages for medium-to-heavy ground vehicles such as high thermal e ciency [1][2][3][4][5] . However, the particulate matter (PM) emission from diesel engine has been a huge problem to the environment [6][7][8][9][10] .…”

This paper discusses the influence of partial region regeneration on both regeneration and emission performance by regeneration test bench. DPF substrate is divided into following four regions on the radial direction by the distribution of thermocouples. For the single region regeneration, region 2 has the highest maximum temperature, maximum temperature gradient, average diameter. The regeneration efficiency decreases when the loading area is far away from the center. The maximum total mass concentration is 0.36mg/m3 at region 4 due to the mass of carbon black loading. For double regions regeneration, the center and adjacent regions have positive effect on maximum temperature, maximum temperature gradient, regeneration efficiency and regeneration performance ration. The maximum total mass concentration and maximum average diameter are 0.2mg/m3 and 34nm at regions 14. For multiple regions regeneration, the lowest maximum temperature and the maximum temperature gradient are 565℃ and 8.3℃/m at regions 134, respectively. Regions 123 have maximum regeneration efficiency, performance ratio, total mass concentration and average diameter. The maximum and minimum average diameters are 101.8nm and 30.2nm at regions 123 and regions 134, respectively.

“…Particulate matter is considered to be exhaust components which leave the exhaust system in a non-gaseous state. Soot particles are most often emitted, having a carbon core that absorbs other small particles, e. g. nitrates, metals or sulphates [9,10]. Along with the installation of the particulate filter, other components such as a broadband lambda sensor, temperature sensors, pressure sensor must also be installed.…”

The aim of the research was to analyse the possibility of using neural networks to determine the parameters of the chemical composition of exhaust gases as a function of engine performance parameters obtained from the on-board diagnostics system such as crankshaft speed and engine load index. The subject of the study was a Fiat Panda car equipped with a 1.3 Multijet diesel engine and powered by pure diesel. The tests used the MAHA MET 6.3 exhaust gas analyser and the on-board diagnostics system OBD II. The obtained values of NO x ,O 2 ,CO 2 and PM measured behind the DPF were analysed. For the purpose of building a neural network model, preliminary studies were carried out in non-urban traffic (high-speed route). On the basis of the data obtained, processes of learning neural network structures with approximate properties with backward propagation of errors were carried out. Subsequently, tests were performed on the operational parameters of the vehicle and the chemical composition of exhaust gases in urban traffic. Analysis of the obtained values of the average parameters obtained during the measurement and on the basis of the prepared neural models allows determining the relative differences at the level of not more than 10 percent.
