1. Characterization of Gasoline Spray-Wall Interactions
Abstract : Interest in spray-wall interactions has intensified recently because of the development of direct injection spark ignition engines. In this type of engine, impingement of the spray on the piston and cylinder walls leads to increased emissions of hydrocarbons and soot. READ MORE

2. Modelling of Multicomponent Fuel Sprays
Abstract : The use of fuel blends (conventional fuels blended with renewable ones) has gained importance in the automotive industry as an option to reduce emissions and dependence on fossil fuels. In order to make the fuel blends commercially viable, computational fluid dynamics (CFD) is used to complement the experiments (done on engines or spray chambers) by providing fundamental insight into spray formation.

3. Optical Diagnostics Applied to Internal Combustion Engines: Catalysis, Sprays and Combustion
Abstract : Gasoline direct injection with spray-guided charge formation is one of the most promising concepts to reduce fuel consumption and CO2 emissions of spark ignited engines. The advantages with the system are owing to un-throttled operation and stratification of the injected fuel resulting in a globally lean combustion. READ MORE

4. Ultra-High Pressure Spray for Gasoline Direct Injection Engines
Abstract : There is an increasingly urgent need for vehicle manufacturers to reduce emissions from passenger vehicles to protect the environment and comply with increasingly stringent emissions standards such as Euro 6d, which came into force in January 2021, and Euro 7, which will probably come into force around 2025. Current emissions standards limit passenger vehicles' particulate number emissions to at most 6*10^{11} [#/km], making it necessary to find ways of reducing the engine-out particulate emissions of gasoline direct injection engines to meet this requirement.
