1. Spark Assisted Compression Ignition, SACI
Sammanfattning : The strong focus on decreasing carbon dioxide emissions due to limited natural resources of fossil fuel as well as alarming climate changes drives the research and development of our prime mover, the combustion engine, faster then ever. The minimum requirement is a power source with increased efficiency while emitting ultra low levels of hazardous local and regional emissions. LÄS MER
2. HCCI Combustion by Retaining Residuals. Development and Analyses of a Method to Reduce Fuel Consumption for Passenger Car Gasoline Engines
Sammanfattning : The demand for more powerful engines on one hand, and greater fuel-efficiency on the other, requires a revolution in engine combustion technology. Homogeneous charge compression ignition (HCCI) can be a fuel-saving, low emissions approach that seems to be very suitable for large displacement passenger car engines. LÄS MER
3. Turbocharged HCCI Engine, Improving Efficiency and Operating Range
Sammanfattning : Increasing fuel prices and environmental concern drives the research and development for the internal combustion engine. Homogeneous Charge Compression Ignition (HCCI) is a promising combustion concept with high fuel efficiency and low emissions. LÄS MER
4. The Low Load Limit of Gasoline Partially Premixed Combustion (PPC) - Experiments in a Light Duty Diesel Engine
Sammanfattning : The decreasing oil supply, more stringent pollutant legislations and strong focus on decreasing carbon dioxide emissions drives the research of more efficient and clean combustion engines. One such combustion engine concept is Homogeneous Charge Compression Ignition (HCCI) which potentially achieves high efficiency and low NOx and soot emissions. LÄS MER
5. Turbo Charged Low Temperature Combustion - Experiments, Modeling and Control
Sammanfattning : Both the global economy and the society in general are dependent on the availability of reliable transportation. Most transportation technology involves the use of internal combustion engines in one way or another. LÄS MER
