  1. 16. Data-Rich Multivariable Control of Heavy-Duty Engines

    Författare :Maria Henningsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariable Control; Model Predictive Control; LQG Control; Virtual Sensing; System Identification; Diesel engines; HCCI engines; Dual-Fuel Combustion; Cylinder Pressure Sensors;

    Sammanfattning : The combustion engine is today the dominant technology for transportation of goods and people world-wide. Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. LÄS MER

  3. 17. Supervisory control for emission compliance of heavy-duty vehicles

    Författare :Mohammed Razaul Karim; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; supervisory control; Euro VI emission legislation; exhaust aftertreatment system; Pontryagin’s minimum principle; E-NMPC.; Diesel engines;

    Sammanfattning : Heavy freight trucks globally contribute to a significant proportion of transport-related air pollution. The dominant air pollutants from heavy freight trucks with diesel engine and exhaust aftertreatment system (EATS) are CO2, hydrocarbons (HC), CO, particulate matter (PM), NOX (NO and NO2), and NH3.

  4. 18. On CFD-Analysis of Heat Transfer of a Heavy-Duty Diesel Engine

    Författare :Helgi Fridriksson; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Heat Transfer; Diesel Engine;

    Sammanfattning : In this work, a heavy-duty diesel engine was studied by employing CFD simulations on a closed volume engine segment. These simulations were used to evaluate both the effects from certain parameters on the wall heat transfer, and to examine how reduction of heat transfer would effect the engine performance and emission levels.

  5. 19. Modeling and Optimal Control of Heavy-Duty Powertrains

    Författare :Vaheed Nezhadali; Lars Eriksson; Giorgio Rizzoni; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powertrain; transmission system; optimal control; modeling for control;

    Sammanfattning : Heavy duty powertrains are complex systems with components from various domains, different response times during transient operations and different efficient operating ranges. To ensure efficient transient operation of a powertrain, e.g. LÄS MER

  7. 20. Gas-Diesel Dual-Fuel Combustion in a Heavy-Duty Engine

    Författare :Zhiqin Jia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Global efforts have been devoted to developing different kinds of alternative fuels in order to reduce the dependence on conventional petroleum fuels. Among these alternative fuels, the compressed natural gas (CNG) is a pop- ular choice because of its relatively clean combustion and global availability at attractive prices. LÄS MER
