1. Large-Eddy Simulation of Gasoline Fuel Spray Injection at Ultra-High Injection Pressures
Abstract : Gasoline direct injection is a state-of-the-art technique that reduces hydrocarbon and particulate emissions. However, further improvement is needed to meet current as well as future emission regulations. READ MORE

2. Thermal insulation of the combustion chamber in a light duty diesel engine
Abstract : Reduction of heat loss from the combustion chamber in an engine has great potential to decrease fuel consumption and CO2 emissions. Research on thermal barrier coatings (TBC) has been performed since the early eighties to address this potential. READ MORE

3. Multiscale granular mechanics: A neutron diffraction based experimental approach
Abstract : Granular media (i.e., assemblies of grains, containing voids), such as sand, are highly complex materials, possessing inherently heterogeneous structure and properties that are manifested by the mobility and interaction of their constituent particles. Despite having been widely studied for centuries (i. READ MORE

4. Studies on Diesel sprays under non-reacting and reacting conditions
Abstract : Methods for reducing engine-out emissions are urgently needed to mitigate climate change and air pollution. In diesel engines, the quality of fuel-air mixing and the subsequent combustion process strongly affect fuel efficiency and engine-out emissions. READ MORE

5. Subcooled boiling flow in liquid-cooled internal combustion engines
Abstract : Road transport sector contributes significantly to emission of carbon dioxide and other greenhouse gases, which negatively impact the global climate. Efficient management of energy, irrespective of the type of propulsion, has the potential to minimize fuel consumption and to reduce emission of greenhouse gases. READ MORE
