RISCycle-to-Cycle NO and NOx Emissions From a HSDI Diesel Engine
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Engine-out NOx emissions from diesel engines continue to be a major topic of research interest. While substantial understanding has been obtained of engine-out (i.e., before any aftertreatment) NOx formation and reduction ...
The Influence of Cycle-to-Cycle Hydrocarbon Emissions on Cyclic NO:NO2 Ratio From a HSDI Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Knowledge of the NO:NO2 ratio emitted from a diesel engine is particularly important for ensuring the highest performance of selective catalytic reduction (SCR) NOx after-treatment systems. As real driving emissions from ...
In-Cylinder CO2 Sampling Using Skip-Firing Method
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Skip-firing (or cylinder de-activation) was assessed as a method of sampling CO2 directly in the cylinder at higher speeds than previously possible. CO2 was directly sampled from one cylinder of a 1 L three-cylinder gasoline ...
