Einsatz Von Partikelfiltern Bei Baumaschinen

Bachelor Thesis aus dem Jahr 2007 im Fachbereich Wirtschaftsingenieurwesen, Note: 1,0, Fachhochschule Technikum, 14 Quellen im Literaturverzeichnis, Sprache: Deutsch, Anmerkungen: Wissenswertes zum Einbau und der Verwendung von Partikelfiltern bei Baumaschinen (Off-Road-Maschinen) , Abstract: The internal combustion process of a diesel engine leads to harmful exhaust emissions. Some of these emissions can be reduced by catalytic reactions, but, e.g., diesel particulates can not be reduced by this procedure. Diesel particulates are small carbon particles which are able to penetrate into the human blood cylcle via the lungs, which furthermore leads to serious health problems.The installation of so called diesel particulate filters into the exhaust systems of captive engines is the state of the art technology for solving the particulate problem. This bachelor paper describes several designs of filters which can be installed into the exhaust systems of diesel engines in construction machines. Futhermore the economic influence caused by the use of such filtering systems will be explained as well. The combustion process and the generation of exhaust gases are basic knowledge for reading this paper, and will therefore be explained too.To prove the efficiency of a common filtering system the author of this paper performed field measurements on an earthmoving machines engine according to a customized testing procedure. Reductions of the CO - and particulate emissions have been proven by these tests.
