  1. 1. The Performance of a Multi Cylinder HCCI Engine using Variable Compression Ratio and Fast Thermal Management

    Author : Jari Hyvönen; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; framdrivningssystem; Variable Compression Ratio; Homogeneous Charge Compression Ignition VCR; termodynamik; Motors and propulsion systems; Termisk teknik; applied thermodynamics; Thermal engineering; Cylinder-to-cylinder; Turbocharging; Multi cylinder; Cylinder balancing; Thermal Management; HCCI;

    Abstract : The prime mover in the world today is the Internal Combustion (IC) engine. The development and improvement of the internal combustion engines since Nicolaus August Otto and Rudolf Diesel has continued until today and will continue long into the future. No major competitor to the IC engine has yet emerged. READ MORE

  2. 2. Estimation of the In-Cylinder Air/Fuel Ratio of an Internal Combustion Engine by the Use of Pressure Sensors

    Abstract : This thesis investigates the use of cylinder pressure measurements for estimation of the in-cylinder air/fuel ratio in a spark ignited internal combustion engine. An estimation model which uses the net heat release profile for estimating the cylinder air/fuel ratio of a spark ignition engine is developed. READ MORE

  3. 3. On Surface Topography of Cylinder Liners

    Author : Zlate Dimkovski; John Westberg; Högskolan i Halmstad; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder liner; Surface Roughness; Characterisation; Honing; Wear; Blechmantel; Groove Parameters; Quality Control; Flow Simulation; Surface engineering; Ytbehandlingsteknik;

    Abstract : The frictional losses, oil consumption and emissions in internal combustion engines are in great extent controlled by the cylinder liner surface topography. This emphasises the importance of: investigating the liner’s topography by objectively characterising it, investigating its effects on the tribological function to gain a better understanding and improving its manufacturing.

  5. 5. Surfaces of Honed Cylinder Liners

    Author : Zlate Dimkovski; B.-G. Rosén; Mohamed El-Mansori; Högskolan i Halmstad; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Honing; Characterisation; Blechmantel; Groove Parameters; Quality Control; Oil Consumption; Wear; Friction; Mixed Lubrication Simulation; Surface engineering; Ytbehandlingsteknik;

    Abstract : Cylinder liner surfaces are often on the agenda of engine developers because of their large influence on the frictional losses, oil consumption and emissions of internal combustion engines. Improving the liner function involves not only manufacturing new surfaces and checking their function but also characterising them as a necessary intermediate step for better understanding of the changes made.
