1. Rhodium diesel-reforming catalysts for fuel cell applications
Abstract : Heavy-duty diesel truck engines are routinely idled at standstill to provide cab heating or air conditioning, and in addition to supply electricity to comfort units such as radio and TV. Idling is an inefficient and unfavorable process resulting in increased fuel consumption, increased emissions, shortened engine life, impaired driver rest and health, and elevated noise. READ MORE

2. Experimental Investigations on Natural Gas-Diesel Dual Fuel Combustion
Abstract : Natural gas has been traditionally applied in spark-ignited combustion engines due to similar combustion characteristics for methane gas and gasoline. However, spark ignition requires a low compression ratio to avoid knock problems and therefore, gas engines have lower efficiency than diesel engines. READ MORE

3. Hydrogen Generation for Fuel Cells in Auxiliary Power Systems
Abstract : Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. READ MORE

4. High Repetition Rate Laser Diagnostics for Combustion Applications
Abstract : High repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. READ MORE

5. Modeling of Diesel Fuel Spray Formation and Combustion in OpenFOAM
Abstract : The formation, ignition, and combustion of fuel sprays are highly complex processes and the available models have various shortcomings. The development and application of multidimensional CFD models, that describe the different phenomena have rapidly increased through the use of commercial and public software (e.g. READ MORE
