6. Full Cycle Engine Simulations with Detailed Chemistry
Sammanfattning : The modeling work developed in this thesis can be divided in two main areas of investigations: autoignition related to spark ignition engine and combustion and emissions formation in relation to diesel engines. A first version of a detailed kinetics engine simulation program, extended to handle full cycle calculations, was employed in order to demonstrate the strong effect that nitric oxide from the residual gas has on the autoignition onset.

7. Reducing Diesel Engine Emissions - An Experimental Investigation
Sammanfattning : In the recent past, the Diesel engine has been improved considerably in the areas ofperformance, fuel efficiency and exhaust emissions. In Europe, these improvements haveresulted in a strong increase in the sales of passenger cars equipped with a Diesel engine. LÄS MER
8. DME and the Heavy Duty Diesel Engine
Sammanfattning : Increasing awareness of adverse anthropogenic environmental effects, such as the effectsof combusting fossil fuels on atmospheric carbon dioxide concentrations, and thatcombustion-related emissions from the transportation sector are going to approachsustainable levels in the near future has led to increased interest in fuels from renewablesources. These fuels offer possibilities to diversify the feedstocks that can be used forfuel production, as well as to reduce fossil carbon dioxide emissions, thereby reducingour dependence on a very limited range of sources.

9. Experimental Investigations of Combustion Chamber Heat Transfer in a Light-Duty Diesel Engine
Sammanfattning : This work concerned experimental studies of heat transfer in a light-duty diesel engine. Combustion is affected by several parameters, such as pressure, engine speed, mass of injected fuel and in-cylinder gas flow. These parameters are in turn affected by the combustion chamber geometry and fuel spray characteristics. LÄS MER
10. Particulate Emissions Associated with Diesel Engine Oil Consumption
Sammanfattning : Particulate emissions from diesel engines have been a key issue for diesel engine developers in recent decades. Their work has succeeded in reducing the exhaust particles from the combustion of fuel, which has led to increasing interest in the contribution of particulates from lubrication oil. LÄS MER
