Pokročilá emisní analýza vznětových a zážehových motorů

Abstract

This diploma thesis deals with theoretical analysis of emission components and practical measurements of petrol and diesel engines emissions. For petrol engines, vehicles with and without catalyst are compared. For diesel engines, vehicles with and without DPF are compared by volume of smoke. Measured vehicles suffer from a variety of motor dysfunctions, which may affect the emission during normal behavior. In advanced emission analysis, there are investigated sizes of solid particles from diesel engines, which occurs for various injection systems with or without DPF filtration.
