Characterisation of the Soot Particles from Diesel Engine Under Different Engine Operating Conditions.

Abstract

This thesis advances the knowledge of the morphology and nanostructure of the soot particles under different engine operating conditions in a diesel engine using a micro-algae-based third-generation biofuel (dioctyl phthalate). The engine operating conditions, such as steady-state, transient, and cold-start influence the shape and structure of the soot particles. These properties of the soot particles affect the functioning of the after-treatment devices, such as diesel oxidation catalysts and diesel particulate filters, which are installed in modern diesel cars.
