  2. 1. Operator and Machine Models for Dynamic Simulation of Construction Machinery

    Author : Reno Filla; Jan-Ove Palmberg; Jonas Larsson; Allan Ericsson; Tobias C. Larsson; Linköpings universitet; []
    Keywords : dynamic simulation; construction equipment; discrete simulation; continuous simulation; operator model; driver model; integrated product development; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : VIRTUAL PROTOTYPING has been generally adopted in product development in order to minimise the traditional reliance on testing of physical prototypes. It thus constitutes a major step towards solving the conflict of actual increasing development cost and time due to increasing customer demands on one side, and the need to decrease development cost and time due to increasing competition on the other.

  5. 3. Numerical Studies of Flow and AssociatedLosses in the Exhaust Port of a Diesel Engine

    Author : Yue Wang; Laszlo Fuchs; Mihai Mihaescu; Angelo Onorati; KTH; []
    Keywords : Internal Combustion Engine; Exhaust flow; Exhaust Valve; Exhaust Port; Large Eddy Simulation; Valve and Piston Motion; Total Pressure Losses; Energy Losses; Discharge coefficient; Flow Losses; Flow structures; Air Flow Bench; Engine-like Conditions; SRA - Energy; SRA - Energi;

    Abstract : In the last decades, the focus of internal combustion engine development has moved towards more efficient and less pollutant engines. In a Diesel engine, approximately 30-40% of the energy provided by combustion is lost through the exhaust gases. The exhaust gases are hot and therefore rich of energy. READ MORE

  6. 4. Studies of a Heavy-Duty Diesel Aftertreatment System Based on the NOX Storage and Reduction Technology

    Author : Klaus Papadakis; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel penalty; injection parameters; DoE; design of experiments; exhaust; diesel engine; NO oxidation; simulation; modelling; oxidation catalyst; NOX trap; NOX storage and reduction; NSR; Kemiteknik och kemisk teknologi; Chemical technology and engineering; dosing strategy; system optimisation;

    Abstract : The legislative limits for NOX emissions in the exhaust gas from heavy-duty diesel engines will be decreased in the European Union from today 3.5 g/kWh (Euro IV) to 2.0 g/kWh in 2008 (Euro V). In the USA and Japan a similar trend can be seen. READ MORE

  7. 5. Homogeneous Ignition - Chemical Kinetic Studies for IC-Engine Applications

    Author : Per Amnéus; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Skeletal mechanism; Mechanism reduction; n-heptane; iso-octane; formaldehyde; methane; Motors and propulsion systems; Motorer; framdrivningssystem; Physics; Fysik; Detailed chemistry; Kinetic calculations; Engine knock; Homogeneous charge compression ignition; HCCI; Fysicumarkivet A:2002:Amnéus;

    Abstract : Calculations on a Homogeneous Charge Compression Ignition (HCCI) engine have been performed. Zero-dimensional models were used. The simplest model compressed the gas to auto-ignition, using temperature and pressure at a certain crank angle position obtained from engine experiments. READ MORE
