1. Quantum-Dot Heat Engines
Abstract : This thesis explores the possibilities of using quantum dots (QDs) in nanoscale energy har- vesters converting heat into electrical energy, i.e. heat engines. From a theory perspective, these possibilities have been investigated for almost two decades, and interest in them seem to continuously increase over time. READ MORE

2. Processes in Optical Diesel Engines - Emissions Formation and Heat Release
Abstract : This project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. READ MORE

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

4. Thermodynamics of microscopic environments: From anomalous diffusion to heat engines
Abstract : Till skillnad från deras makroskopiska motsvarigheter utvecklas inte mikroskopiska system deterministiskt på grund av inverkan från termiskt brus. Sådana system är föremål för fluktuationer som endast kan studeras inom ramen för stokastisk termodynamik. READ MORE

5. Waste Heat Recovery in Heavy Duty Diesel Engines
Abstract : Over 50% of the energy released by burning fuel in a truck engine is lost as heat rather than being used to propel the vehicle. A promising method for capturing and reusing this heat, and thereby improving engine efficiency, is to exploit thermodynamic cycles for waste heat recovery (WHR). READ MORE
