    Abstract : 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. READ MORE

  6. 19. Gasoline Partially Premixed Combustion - An Advanced Internal Combustion Engine Concept Aimed to High Efficiency, Low Emissions and Low Acoustic Noise in the Whole Load Range

    Author : Vittorio Manente; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Environmental concerns such as global warming, the surge of crude oil prices and more stringent emission regulations are demanding the development of internal combustion engines that are highly efficient and low polluting. With classical internal combustion engine concepts such as diesel compression ignition and gasoline spark ignition engines, a trade-off exists between local and global emissions i. READ MORE

  7. 20. Investigation of PPC in an Optical Engine : With focus on Fuel Distribution and Combustion Characterization

    Author : Sara Lönn; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical engine; PPC; Fuel distribution; Methanol;

    Abstract : The global society is dependent on transportation to function and a big part of these transports are driven by an internal combustion engine. Heavy-duty vehicles utilizes conventional diesel combustion is a combustion concept where the fuel is often ignited during the injection event and while it gives a high combustion efficiency, the combustion mode is also characterized by high emission of NOx and soot.
