  1. 21. MODELLING POLYGENERATION WITH DESICCANT COOLING SYSTEM FOR TROPICAL (AND SUB - TROPICAL) CLIMATES

    University essay from KTH/Energiteknik

    Author : Lekha Udayanganie Bakmeedeniya; [2011]
    Keywords : Polygeneration; Desiccant cooling; Humidity ratio; Coefficient of Performance;

    Abstract : Modelling Polygeneration with Desiccant Cooling System for Tropical(and Sub Tropical) ClimatesAbstractSpace cooling has become a necessity in tropical countries. Maintainingcomfortable indoor conditions in industrial environments incur high energy bills due toheavy dependency on electrically operated air conditioning systems. READ MORE

  3. 22. Recovery of un-combusted fuel in a gas turbine power cycle with Chemical Looping Combustion.

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Jonas Gunnarsson; [2010]
    Keywords : Chemical Looping Combustion CLC un-combusted fuel gas turbine power cycle; Technology and Engineering;

    Abstract : Chemical Loping Combustion (CLC) is a novel combustion technology in which the exhaust gas is inherently divided into oxygen depleted air in one stream and CO2 and water vapour in another. This is however under the ideal condition that the fuel conversion is complete, i.e. READ MORE

  4. 23. Modeling and Control of Retarder using On/Off Solenoid Valves

    University essay from KTH/Reglerteknik

    Author : Vidar Steinsland; [2008]
    Keywords : ;

    Abstract : The Retarder is one of the main components in Scania's trucks' braking system and is used to brake down the truck and for maintaining a steady speed on descents. This Master's Thesis aims to investigate if the current system which uses a proportional valve to control the air pressure in the Retarder, can be replaced with two on/o® solenoid valves and a pressure chamber to control the air pressure, which would result in a cheaper and more robust system.

  5. 24. Investigation of Correlations Between COV of Ion Integral and COV of IMEP in a Port-Injected Natural-Gas Engine

    University essay from Institutionen för systemteknik

    Author : Johan Molin; [2008]
    Keywords : COV; IMEP; Ion current; EGR;

    Abstract : Correlations between the coefficient of variations (COV) of ion current integrals and COV of indicated mean effective pressure (IMEP) are investigated. The investigations are made to see if there is a possibility to use ion sense technique for closed loop combustion control to maximize Exhaust Gas Recirculation (EGR) level with remaining combustion stability.

  6. 25. Modelling of an EGR System

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Fredrik Olin; [2007]
    Keywords : EGR; mean value engine model; and poppet valve.; Technology and Engineering;

    Abstract : Due to new emission legislations in Europe and in the USA truck manufacturers are facing new difficulties when it comes to meeting these demands. This new legislation will demand more accurate models for simulation and malfunction diagnosis. READ MORE
