1. 1. Heat-pipes in electric machines : Heat management in electric traction motors

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Anton Olofsson; [2022]
   Keywords : Heat-pipe; Heat pipe; FEM; LPM; Traction motors; Induction motor; Heat management;

   Abstract : The world is continually changing towards more energy efficient alternatives and less pollution. For the traction market, electric powertrains have become the go-to method, superior to both steam and diesel-electric hybrid systems. READ MORE

3. 2. Evaluation of transition towards zero emission commuter ferries : Comparative Analysis of Fuel-based and Battery-based Marine Propulsion System from financial and environmental perspectives

   University essay from KTH/Marina system

   Author : Varun Goel; Sonja Wadelius; [2021]
   Keywords : Water-borne public transport; Maritime industry; marine propulsion system; marine Li-ion batteries; diesel-electric; diesel-mechanical; all-electric; life cycle assessment; cost assessment.; Vattenburenkollektivtrafik; marinaindustrin; marinaframdrivningssystem; marinabatterisystem; dieselelektrisk; diesel mekanisk; helt elektrisk; livscykelanalys; kostnadsanalys.;

   Abstract : The purpose of this study is to compare the life-cycle cost and environmental impact of the existing fuel-based propulsion system, on public commuter ferries in Stockholm, with a battery based propulsion system. The study is divided into multiple layers. READ MORE

4. 3. Development of Push Control Strategy for Diesel-Electric Powertrains

   University essay from Linköpings universitet/Fordonssystem

   Author : Johannes Bodin; [2018]
   Keywords : diesel-electric powertrain; control strategy; push control; genset;

   Abstract : In diesel-electric powertrains, the wheels are mechanically decoupled from the internal combustion engine (ICE). The conventional control approach for such a powertrain is to let the driver control the traction motor while the ICE realizes speed control, causing power to be pulled through the powertrain.

5. 4. Numerical Optimal Control of Hybrid Electric Trucks : Exhaust Temperature, NOx Emission and Fuel Consumption

   University essay from Linköpings universitet/Fordonssystem

   Author : Fredrik Andersson; Hampus Andersson; [2018]
   Keywords : Numerical optimal control; HEV; Diesel electric hybrid truck; Exhaust temperature; Emissions; NOx; SCR;

   Abstract : The controls for a parallel hybrid electric truck are optimized using numerical optimal control. Trade-offs between catalyst light-off times, NOx emission and fuel consumption have been investigated for cold starts at two operating points, as well as temperature differences between conventional and hybrid powertrains during WHTC (World Harmonized Transient Cycle).

6. 5. Electrification of a diesel-hydraulic off-road machine

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Dhruv Phadke; [2017]
   Keywords : driveline control; efficiency; energy storage; XT28; drivlina; energilagring; reglering; XT28; verkningsgrad;

   Abstract : This report is for the Master of Science thesis project undertaken for KTH Royal Institute of Technology in collaboration with the Forestry Research Institute of Sweden (Skogforsk) for the Forestry Master Thesis School. The aim of this project was to theoretically explore the possibility of replacing the hydraulic driveline with an electric series driveline and to understand the differences between using one or the other so that it can be convincingly concluded if a Diesel-electric driveline in Forestry forwarders is a worthwhile endeavour or not.
