1. Spray combustion with multiple-injection in modern engine conditions
Sammanfattning : Combustion of fuel in diesel engines emits substances harmful to the environment such as soot. These emissions can be reduced by either in-cylinder treatments or after-treatments. One of the common in-cylinder treatments is multiple-injection, which divides a single fuel injection to multiple smaller injections. LÄS MER
2. On the Combustion Characteristics of Closely-Coupled LD Diesel Injection Strategies
Sammanfattning : Multiple-pilot injection strategies with both moderate and short time separations (dwells) are investigated in a light-duty diesel engine. Both conventional and optical engine experiments are performed. LÄS MER
3. High Octane Number Fuels in Advanced Combustion Modes for Sustainable Transportation
Sammanfattning : The research community recently proposed a low-temperature combustion (LTC) concept that can simultaneously reduce Nitrogen Oxides (NOx) and soot emissions while maintaining high engine efficiency. Given that diesel fuel is prone to preignition with early injection, gasoline-like fuel with high octane number is utilised to provide sufficient ignition delay and extend the load range. LÄS MER
4. Management of technology in the process industries: Matching market and machine
Sammanfattning : The process industries span multiple industrial sectors and constitute a substantial part of the entire manufacturing industry. Since companies belonging to this family of industries are often very asset intensive, their ability to respond to changes is often limited in the short term. LÄS MER
5. Design and Optimization of In-Cycle Closed-Loop Combustion Control with Multiple Injections
Sammanfattning : With the increasing demand of transportation, biofuels play a fundamental role in the transition to sustainable powertrains. For the increased uncertainty of biofuel combustion properties, advanced combustion control systems have the potential to operate the engine with high flexibility while maintaining a high efficiency and robustness.
