1. Advancing the Limits of Dual Fuel Combustion
Abstract : There is a growing interest in alternative transport fuels. There are two underlying reasons for this interest; the desire to decrease the environmental impact of transports and the need to compensate for the declining availability of petroleum. In the light of both these factors the Diesel Dual Fuel, DDF, engine is an attractive concept. READ MORE

2. Combined Energy Systems Applied to Productive Sectors: The Case of Dairy Farms in Central Bolivia
Abstract : Most energy solutions in developing countries focus primarily on solving domestic energy demands of their growing populations without due consideration of sustainable development. On the other hand, in most of these countries, a segment of energy users that has not received enough attention from governments and institutions regarding appropriate energy solutions is the productive sector.

3. Dual-Fuel Combustion in a Heavy-Duty Engine
Abstract : The need to control climate change and improve the fuel effieciency of internal combustion engines has prompted global efforts to develop alternative fuels in order to reduce dependence on conventional petroleum derivatives. This thesis deals with three such alternative fuels: compressed natural gas (CNG), pure methane (used to mimic biogas), and methanol. READ MORE

4. Gas-Diesel Dual-Fuel Combustion in a Heavy-Duty Engine
Abstract : Global efforts have been devoted to developing different kinds of alternative fuels in order to reduce the dependence on conventional petroleum fuels. Among these alternative fuels, the compressed natural gas (CNG) is a pop- ular choice because of its relatively clean combustion and global availability at attractive prices. READ MORE

5. Diluted Operation of a Heavy-Duty Natural Gas Engine - Aiming at Improved Effciency, Emission and Maximum Load
Abstract : Most heavy-duty engines are diesel operated. Severe emission regulations, high fuel prices, high technology costs (e.g. catalysts, fuel injection systems) and unsustainably in supplying fuel are enough reasons to convenience engine developers to explore alternative technologies or fuels.
