  1. 1. Low Temperature Waste Heat Recovery in Internal Combustion Engines

    University dissertation from Department of Energy Sciences, Lund University

    Author : Vikram Singh; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low Temperature Waste Heat Recovery; Rankine cycle; Coolant Temperature; Working Fluids;

    Abstract : Over the past few decades, the automotive industry has increasingly looked towards increasing the efficiency of the internal combustion engine to meet more stringent emission norms and as a measure to meet demands for improved air quality in cities. One method to improve the internal combustion engine efficiency is to recover some of the energy lost to the coolant and the exhaust using a secondary thermodynamic cycle such as an Organic Rankine Cycle.

  2. 2. Waste Heat Recovery from Combustion Engines based on the Rankine Cycle

    University dissertation from Department of Energy Sciences, Lund University

    Author : Gunnar Latz; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste heat recovery; Rankine cycle; piston expander;

    Abstract : Most of the energy in the fuel burned in modern automotive internal combustion engines is lost as wasteheat without contributing to the vehicle’s propulsion. In principle some of this lost energy could becaptured and used to increase the vehicle’s fuel efficiency by fitting a waste heat recovery system to theengine. READ MORE

  3. 3. Design of Thermoelectric Generators for Automotive EGR Applications

    University dissertation from Department of Energy Sciences, Lund University

    Author : Olle Högblom; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact resistances; Exhaust gas heat recovery; Thermoelectrics; CFD;

    Abstract : Rising energy prices and greater environmental awareness along with stringent emissions legislation in the automotive industry make it possible to introduce techniques in the aftertreatment system that have previously been unprofitable. One such technique, studied in this work, is heat recovery in the exhaust gas recirculation (EGR) cooler using thermoelectric generators (TEG). READ MORE

  4. 4. Carbon Recovery in A Dual Fluidized Bed Gasifier

    University dissertation from Department of Energy Sciences, Lund University

    Author : Sébastien Pissot; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; recycling; dual fluidized bed; chemical looping gasification; circular economy; carbon recovery; biomass; plastic waste;

    Abstract : As the concept of a circular economy gains acceptance and awareness of climate change and its disastrous consequences increases, the ways in which we produce the carbon-based goods upon which so much of our economy depends need to change. Society must end its reliance on fossil carbon resources and shift to renewable sources that enable the establishment of a carbon cycle. READ MORE

  5. 5. Heat treatment of Al-Si-Cu-Mg casting alloys

    University dissertation from Department of Energy Sciences, Lund University

    Author : Emma Sjölander; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast aluminium alloys; Plastic Deformation; Microstructure; Tensile Properties; Heat Treatment; Modelling; Solution Treatment; Artificial Ageing;

    Abstract : Environmental savings can be made by increasing the use of aluminium alloys in the automotive industry as the vehicles can be made lighter. Increasing the knowledge about the heat treatment process is one task in the direction towards this goal. The aim of this work is to investigate and model the heat treatment process for Al-Si casting alloys. READ MORE
