    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; framdrivningssystem; Motors and propulsion systems; efficiency; emissions; combustion; HCCI; engine;

    Abstract : 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. READ MORE

  3. 3. Torque based combustion property estimation and control for diesel engines

    Author : Mikael Thor; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Crankshaft torque measurements; Engine control; Combustion modeling; Diesel engines; Closed-loop control; Internal combustion engines; Combustion property estimation; Combustion phasing;

    Abstract : Modern diesel engines are becoming increasingly complex as a result of demands on the reduction of both fuel consumption and emissions. This escalating complexity not only applies to the engine itself, but also to its control system. READ MORE

  4. 4. Numerical Investigation of Internal Combustion Engine Related Flows

    Author : Martin Söder; Laszlo Fuchs; Martin Tunér; KTH; []

    Abstract : Internal combustion engines has been used for more than 100 years. The use of the abundant energy supply stored as hydrocarbon fueled unprecedented economic growth. The use of hydrocarbons increased the work output of human labor significantly, thus increasing the economy and prosperity. READ MORE

  5. 5. Experimental Investigations of Combustion Chamber Heat Transfer in a Light-Duty Diesel Engine

    Author : Jessica Dahlström; Förbränningsmotorer; []
    Keywords : internal combustion engines; heat transfer; diesel engine; Diesel combustion; combustion chamber geometry; piston geometry; spray parameters;

    Abstract : 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. READ MORE
