Current ecological trends and resulting legislation like European emissions standards Euro 6d or Best Available Techniques are setting new challenges in the field of environmental protection. Since the problem of emissions of particulate matter from diesel engines was solved by the application of diesel particulate filters (DPFs or FAPs) and due to the global dominance of gasoline fuelled passenger...
The paper presents measurements of PM emission in the exhaust gas of a gasoline fueled SI engine alternatively fueled with LPG. The research was performed on a 170.A1 engine using the Dekati ELPI+ PM analyzer and Micro Diluter 6100 (a micro-dilution tunnel). The author also measured the concentration of exhaust gaseous components with the use of Horiba MEXA 1500GH analyzer. The author compared the...
Reduction of NOx- and particle emissions of Diesel engines is worldwide an important challenge for the engineers. Some unregulated components, like NO2, NH3 and nanoparticles NP came in the focus of attention in the last years. Application of EGR and / or SCR can lower NOx, using RME (Bxx) can increase NOx. What happens with NP, parameter which enters in some further steps of exhaust gas legislation...
