6. System Simulation of Partially Premixed Combustion in Heavy-Duty Engines : Gas Exchange, Fuels and In-cylinder Analysis
Sammanfattning : The concept of partially premixed combustion (PPC), applied to conventional diesel engines, has shown to yield high gross efficiencies and low emissions of oxides of nitrogen and soot. PPC emerged from the knowledge gained from homogeneous charge compression ignition (HCCI) research. LÄS MER
7. Simulation of Combustion and Mixture Formation for Gasoline Direct Injection Engine Application
Sammanfattning : The development and introduction of new engine technologies are primarily motivated by the need to comply with increasingly stringent emissions legislation and to reduce fuel consumption. One of the most important of these new engine technologies is direct gasoline injection, which is considered to be an important and cost-effective measure to meet both targets. LÄS MER
8. Numerical Modelling of Fuel Injection and Stratified Turbulent Combustion in a Direct-Injection Spark-Ignition Engine Using an Open Source Code
Sammanfattning : Stringent regulations on the emission of pollutants, especially carbon dioxide (CO2), necessitate the development of advanced combustion technologies. Gasoline direct injection (GDI) into the combustion chamber of a Spark Ignition (SI) engine is a combustion strategy that is widely recognized as having the potential to improve fuel efficiency of internal combustion engines for passenger cars.

9. Large-Eddy Simulation of Gasoline Fuel Spray Injection at Ultra-High Injection Pressures
Sammanfattning : Gasoline direct injection is a state-of-the-art technique that reduces hydrocarbon and particulate emissions. However, further improvement is needed to meet current as well as future emission regulations. LÄS MER
10. A Study on Spray-Guided Stratified Charge Systems for Gasoline DI Engines
Sammanfattning : Innovative technologies are required to meet ongoing challenges to reduce the CO2 emissions from passenger cars and their fuel consumption. Such technologies are usually complex and require detailed analyses to deliver efficient, reliable systems. LÄS MER
