    Sammanfattning : During the last decade an alternative to conventional internal combustion engines, i.e. spark-ignited and Diesel engines, has been under investigation by an ever-increasing number of research groups. LÄS MER

  3. 2. HCCI Combustion - Engine Operation and Emission Characteristics

    Författare :Magnus Christensen; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; framdrivningssystem; Motors and propulsion systems; efficiency; emissions; combustion; HCCI; engine;

    Sammanfattning : The potential and limitations of the Homogeneous Charge Compression Ignition (HCCI) engine concept has been experimentally investigated. The operation range, in terms of usable air/fuel ratio and engine load, and the emission characteristics have been studied. An 1. LÄS MER

  4. 3. Alternative Combustion Strategies for Gasoline Engines

    Författare :Daniel Dahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; engines; SI; SGDI; CAI; HCCI; Otto; lean burn; gasoline; combustion; fuel consumption;

    Sammanfattning : Due to increasingly strict legislative demands and customer concerns regarding CO2emissions, there is a need to develop and implement new combustion strategies forgasoline (Otto) engines. In attempts to meet this need, most attention is focusing onthe low load/speed range where the classic spark ignition strategy (SI) has poorefficiency, mainly due to the throttling of the intake air causing pumping losses.

  5. 4. Gasoline Engine HCCI Combustion - Extending the high load limit

    Författare :Daniel Dahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NVO; stratified charge; gasoline engine; high load; knock.; HCCI; stoichiometric; CAI; ringing; SCCI;

    Sammanfattning : There is an increasing global focus on reducing emissions of greenhouse gases.For the automotive industry this means reducing CO2 emissions of the vehiclesmanufactured, which is synonymous with reducing their fuel consumption oradapting them for using renewable fuels. LÄS MER

  7. 5. Optical Diagnostics of Gasoline Compression Ignition : HCCI-PPC-Diffusion Combustion

    Författare :Marcus Lundgren; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical engine; LTC; HCCI; PPC; Gasoline; High load;

    Sammanfattning : Access to clean and affordable energy is one of the cornerstones of the world's society. Since the introduction of the internal combustion engine, diesel engines have become widely used for transportation in the commercial sector. LÄS MER
