1. A Two-Stroke Range Extender Engine For Heavy Duty BEV applications
Sammanfattning : A back-up range extender (REX) is proposed to support battery electric vehicles (BEV) for heavy duty applications. A single cylinder crank case scavenged two-stroke SI-internal combustion engine (ICE) with a turbocharger system is considered powerful and small enough to be installed directly on the existing electric machine in the electric powertrain.

2. Modeling and Control of EGR on Marine Two-Stroke Diesel Engines
Sammanfattning : The international marine shipping industry is responsible for the transport of around 90% of the total world trade. Low-speed two-stroke diesel engines usually propel the largest trading ships. This engine type choice is mainly motivated by its high fuel efficiency and the capacity to burn cheap low-quality fuels.

3. In-Nozzle Flow and Primary Breakup Investigations of Marine Two-Stroke Diesel Engine Injectors
Sammanfattning : This thesis will focus on the experimental studies of in-nozzle flow and primary breakup of pressure-atomized fuel sprays as used in large marine two-stroke Diesel engines. To further increase the efficiency of large marine two-stroke Diesel engines, a better understanding of the fuel spray atomization process is necessary. LÄS MER
4. In-Nozzle Flow, Spray and Combustion Investigations of Two-Stroke Marine Diesel Engine Fuel Injectors
Sammanfattning : This thesis focuses on the experimental studies of the cavitating in-nozzle flow of large two-stroke marine Diesel engine fuel injector nozzles and how it affects the spray morphology and combustion behaviour. To further increase the efficiency of large two-stroke marine Diesel engines, a better understanding of the fuel spray atomization process is necessary. LÄS MER
5. Alkylate Petrol. Environmental Aspects of Volatile Hydrocarbon Emissions
Sammanfattning : All hydrocarbons emitted from production and use of petrol are hazardous to human health and the environment, but to a different extent for individual compounds. This thesis compares and characterizes C2-C8 hydrocarbons related to alkylate petrol and conventional petrol. LÄS MER
