THE STUDY TROUGH MODELING OF AFTER-TREATMENT
SYSTEM FOR EXHAUST GASES FROM INTERNAL
COMBUSTION ENGINES
The present work shows a detailed analysis of gases after-treatment
systems for modern spark engines with different components installed, by
generating a simulation research of the working phenomenology and
parameters. It outlines the specific field of gas after-treatment methods (with
modern catalytic components) developed for spark ignited engines, specifically
the energy and economy improving possibilities through simulation of the final
evacuation process of gases. There is considered that the gas evacuation and
exhaust system architecture besides the catalytic converter have a major
influence upon the phenomena of gas flow and also on the engine economy
and pollution. Modeling and simulating the after-treatment systems on spark
ignited engines may lead to a multitude of engineering acts and improvement
strategies in order to optimize the environmental performance and fuel
economy, while the engine dynamic performance will be accurately managed.
Today in European Union the specific regulations in antipollution domain and oil
independence in relation with the Middle East are more often discussed, being
high priorities on the institutional and executional panel. The present article
outlines the issue of modeling/simulating exhaust engine systems and
improving the existing components but with significant changes which must
comply with the law requirements of reduced pollution and low consumption.
