Potenziale einer Voreinspritzung zur Steuerung der Verbrennungsführung an schweröltauglichen Großdieselmotoren

Universität Rostock, 2015

Abstract: The scope is the reduction of Exhaust-Gas-Emissions by use of HFO in Diesel Engines. Different pre-injection strategies, were evaluated based on introduced parameters “standard deviation of cylinder pressure curves” and “Intensity of the Diffusions-Phase”. A approach of an early pre-injection was substantiated and validated at a research engine. Their potential for stabilising ignition as well as improving the combustion and the Soot- and NOx- emissions under unfavourable ignition- and combustion-conditions was confirmed at delayed combustion and the application of exhaust gas recirculation.
