  2. 1. Study of a Pneumatic Hybrid aided by a FPGA Controlled Free Valve Technology System

    Author : Sasa Trajkovic; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressor; Air-motor; Pneuamtc; Pneumatic-hybrid; VVT; Valve; regenerative; Hybrid; Air;

    Abstract : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. READ MORE

    Author : Clement Chartier; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel; Combustion; Soot; UHC; Injections; Lift-off length; air-entrainement;

    Abstract : Internal combustion engines have been an important technological field for more than a century. It has had an important impact on society through improved transportation and industrial applications. READ MORE

  5. 3. Investigations of Diesel Sprays in Optical Engines - Liquid Fuel Penetration and Lift-Off Length

    Author : Guillaume Lequien; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed imaging; liquid penetration; lift-off length; soot; optical engine; Diesel sprays;

    Abstract : Diesel engines are widely used as powertrain solutions for transportation vehicles. Their low fuel consumption and high performance make them attractive, however, their associated pollutant emissions is a major drawback which represent a hazard for public health and the environment.

  6. 4. Experimental study of single fuel jet combustion and high-cycle regenerative systems

    Author : Simon Lille; KTH; []
    Keywords : combustion; preheated air; energy savings;

    Abstract : High Temperature Air Combustion (HTAC) is a technique toreduce consumption of fuel and decrease NOxformation in furnaces. The main change that occursin the furnace chamber is that the flow pattern of flue gasesaltered resulting in a more uniform heat transfer andtemperature profile. READ MORE

  7. 5. Fluid dynamics and flow structures of wood fibres suspended in gas flows

    Author : Olof Melander; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; two-fluid model; fibres; flocculation; multiphase flow; flow regimes; particle transport; fibre suspensions; Particle Image Velocimetry; Computational Fluid Dynamics; lift force; concentration measurement;

    Abstract : The flow of wood fibres suspended in gas plays a major role in the MDF (Medium Density Fibreboard) production process. Development of machinery in this industry has traditionally been based on experience. Only recently has the use of numerical methods such as CFD (Computational Fluid Dynamics) become an important part of the development process. READ MORE
