  1. 1. Exhaust Heat Utilisation and Losses in Internal Combustion Engines with Focus on the Gas Exchange System

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Habib Aghaali; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; heat transfer; heat loss; exhaust heat utilisation; waste heat recovery; turbocompound; divided exhaust period; internal combustion engine; gas exchange; pumping loss; variable valve timing; WHR; DEP; Turbo; värmeöverföring; värmeförluster; avgasvärme utnyttjande; förluster vid värmeåtervinning; turbocompound; delad avgasperiod; förbränningsmotor; gasväxling; pumpningsförlust; variabla ventiltider; WHR; DEP; Farkostteknik; Vehicle and Maritime Engineering; Energiteknik; Energy Technology;

    Abstract : Exhaust gas energy recovery should be considered in improving fuel economy of internal combustion engines. A large portion of fuel energy is wasted through the exhaust of internal combustion engines. Turbocharger and turbocompound can, however, recover part of this wasted heat. READ MORE

  2. 2. On-Engine Turbocharger Performance Considering Heat Transfer

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Habib Aghaali; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbocharger; Internal combustion engine; heat transfer; turbocharged engine; on-engine turbocharger; turbocharger performance; توربو شارژر، موتور احتراق داخلی، انتقال حرارت، توربوچارجر; turbo; turboladdare; förbränningsmotor; värmeöverföring; turboladdad motor;

    Abstract : Heat transfer plays an important role in affecting an on-engine turbocharger performance. However, it is normally not taken into account for turbocharged engine simulations. READ MORE

  3. 3. Analysis of a novel Transversal Flux Machine with a tubular cross-section for Free Piston Energy Converter application

    University dissertation from Stockholm : KTH

    Author : Alija Cosic; KTH.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Electrical engineering; electronics and photonics Electronic measurement and instrumentation; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronisk mät- och apparatteknik;

    Abstract : Constantly growing need for oil, all over the world, has caused oil price to rise rapidly during the last decade. High oil prices have made fuel economy as one of the most important factors when consumers are buying their cars today. READ MORE

  4. 4. Large Eddy Simulations of Complex Flows in IC-Engine's Exhaust Manifold and Turbine

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Johan Fjällman; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large Eddy Simulations; Reynolds Averaged Navier-Stokes; Turbocharger; Turbine; Curved Pipes; Pulsatile Flow; Proper Orthogonal Decomposition; Large Eddy Simulations; Reynolds Averaged Navier-Stokes; Turboladdare; Turbin; Rörkrök; Pulserande Flöde; Proper Orthogonal Decomposition; Teknisk mekanik; Engineering Mechanics;

    Abstract : The thesis deals with the flow in pipe bends and radial turbines geometries that are commonly found in an Internal Combustion Engine (ICE). The development phase of internal combustion engines relies more and more on simulations as an important complement to experiments. READ MORE

  5. 5. Combustion Bowl Heat Transfer Analysis in Diesel and PPC Engines

    University dissertation from Department of Energy Sciences, Lund University

    Author : Helgi Fridriksson; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat Transfer; CFD; Internal Combustion Engine; Diesel; PPC;

    Abstract : This thesis concerns a numerical investigation on heat transfer in internal combustion engines, with the aim of increasing engine efficiency. The efficiency gains are to be extracted from reduced heat transfer losses, by increasing the knowledge on how the heat transfer process is affected by various hardware and operational parameters in the engine.
