1. Transient Spray Mode Fuel Injection
Abstract : This research examines the pivotal role of transient fuel spray in internal combustion engines, primarily focusing on their influence on dual-fuel (DF) engines. In the case of dual-fuel (DF) engines functioning in a gas mode, the controlling of the primary fuel’s ignition is usually managed through the direct injection of liquid pilot fuel. READ MORE

2. Experimental Investigation of ultra-high fuel injection pressure spray for GDI engines
Abstract : Gasoline Direct Injection Engines (GDI) for passenger cars currently use fuel injection systems operating at pressures of up to 350 bar. Injection pressures have increased over time, and there is evidence that particulate emissions could be reduced by raising them further, up to 500 bar. READ MORE

3. Large-eddy simulation on the effects of fuel injection pressure on gasoline spray characteristics
Abstract : Increasing the injection pressure in gasoline direct injection engines has a substantial potential to reduce emissions while maintaining high efficiency in spark ignition engines. Present gasoline injectors operate at pressures of 20 to 30 MPa. READ MORE

4. Reactions in the Lower Part of the Blast Furnace with Focus on Silicon
Abstract : The thermodynamic conditions for the behaviour of silicon in the lower part of the blast furnace have been the focus of the thesis. More specifically, the influences of temperature, carbon activity, total gas pressure and Fe reoxidation on silicon have been studied. READ MORE

5. 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
