Měření exhalací zážehových a vznětových motorů

Abstract

This bachelor thesis is dealing with theoretical analysis and practical emission measuring of petrol and diesel combustion engines. Its goal, in theoretical part, is to describe emission exhaust fumes composition, how are these emission currently measured, what is the measurement procedure and what is the allowed quantity of the emission in exhaust fumes. In practical part is main goal to determine, what influences do the most often occuring engine failures have over emissions and what is the reason of some failures not to have influence over emission at all, and even if the car is showing signs of failure.
