1. Empirical combustion modeling in SI engines
Sammanfattning : This licentiate thesis concerns the modeling of spark ignition engine combustion for use in one dimensional simulation tools. Modeling of knock is of particular interest when modeling turbocharged engines since knock usually limits the possible engine output at high load. LÄS MER
2. On Alternative Fuels for Internal Combustion Engines : A study of biodiesel, gaseous methane and methanol
Sammanfattning : This thesis covers some of the environmental impacts of internalcombustion engines running on alternative fuels. The focus of thestudies conveyed is the reduction of greenhouse gases and particleemissions, as these two factors are of great importance for the pathsthat road transportation is facing. LÄS MER
3. Flow measurements using combustion image velocimetry in diesel engines
Sammanfattning : This work shows the in-cylinder airflow, and its effects on combustion and emissions, in a modern, heavy-duty diesel engine. The in-cylinder airflow is examined experimentally in an optical engine and the flow field inside the cylinder is quantified and shown during combustion, crank angle resolved. LÄS MER
4. Experiments on Heat Transfer During Diesel Combustion Using Optical Methods
Sammanfattning : Transportation is a crucial part of modern societies. This includes their economies. Trade and the transportation of goods have a great influence on prosperity. Nevertheless, the transportation sector with road transport in particular is heavily dependent on fossil fuels and emits a significant amount of greenhouse gases. LÄS MER
5. Mitigating Knock in Heavy Duty Spark Ignition Engines : Experiments and simulations of diluted ethanol and methanol combustion
Sammanfattning : To effectively reduce fossil fuel dependence in the transport sector, an unprecedented increase in renewable fuel production is required. Short chain alcohols, such as ethanol and methanol, are well placed as they can be produced in a variety of renewable pathways from most carbon sources. LÄS MER
