16. Chemistry of Combustion Products Investigation of Combustion Chamber Deposits Formed in a Gasoline Direct Injection Stratified Charge SI Engine
Sammanfattning : The aim of this work was to characterize deposits formed in the combustion chambers of a gasoline direct injection stratified charge SI engine. The engine was run with several types of gasoline fuels and a special reference engine oil. LÄS MER
17. Spray Processes in Optical Diesel Engines - Air-Entrainement and Emissions
Sammanfattning : Internal combustion engines have been an important technological field for more than a century. It has had an important impact on society through improved transportation and industrial applications. LÄS MER
18. A Detailed Kinetic Model for Calculation of the Soot Particle Size Distribution Function
Sammanfattning : The soot particle size distribution was studied via numerical simulation under diesel like engine conditions using a detailed kinetic soot model. Two different mathematical methods of the soot model description have been used in this work. In the first part of the work, the method of moments is presented. LÄS MER
19. OH and Soot Optical Diagnostics for Combustion Applications for Combustion Applications
Sammanfattning : Optical diagnostics are remote non-intrusive sensing techniques. The thesis work concerns the use of OH and soot optical diagnostics for combustion research.Internal combustion (IC) engines are widely used for the generation of power and for transportation purposes. LÄS MER
20. Zero and Multi-Dimensional Modeling of Internal Combustion Engines with respect to Ion Current and Soot Formation
Sammanfattning : The work presented in this thesis can be divided into the three following fields of investigation: First of all the ionization model developed in this thesis is meant to simulate the thermal ionization process or the so-called second peak. Equilibrium assumptions have been adopted for the modeling of the thermal ionization, in which Saha’s equation was derived for singly ionized molecules. LÄS MER
