Quantification Of Auto-Ignition In Diesel Engines
… due to fuel evaporation and piston movement (in engines) an effective temperature value is used. Different definitions for the effective temperature have been reported in the literature. This leads to more variations in the activation energy value calculation. Furthermore, it was observed that …

Fuel composition and quality sensing for diesel engines
ABSTRACT The range of fuels that a diesel engine may be expected to burn is increasing including the use of biodiesels and alcohols produced from various plant or animal sources. Moreover, fuels can become unsuitable for application in diesel engines due to a variety of contamination, degradation, …

In Cylinder NOx Control Technologies for Marine Diesel Engines
… 6 cylinder, 4 strokes, medium speed marine diesel engine, to evaluate their potential in order to reach the IMO Tier 3 NOx emissions target. By means of extreme Miller cycles, with Early Intake Valve Closures (EIVC up to 100 crank angle degrees before BDC), a shorter compression stroke and …

Combustion simulations in Diesel engines using reduced reaction mechanisms
… which are important for pollutant prediction in Diesel engines: ignition, chemistry and radiation. Ignition was tracked by means of a representative species (here CO), whose concentration remains small during the ignition period and which shows an increase at ignition. Its reaction rate was …

Analysis of parasitic losses in heavy duty diesel engines
Fuel economy of large, on-road diesel engines has become even more critical in recent years for engine manufactures, vehicle OEMs, and truck operators, in view of pending CO2 emission regulations. Demands for increased fuel economy are coupled with corresponding improvements in engine performance, …

Particle matter emission control and related issues for diesel engines
… probably one of the most critical issues of the diesel engine emissions. After years of research, people begin to understand it further, with respect to its impact on the environment and human health, its formation mechanism inside and outside the diesel engine, and most importantly, the methods …

Characterization of in-use emissions from on-highway heavy-duty diesel engines
Class-8 trucks with GVWR of 80,000 lbs were tested on different driving routes and in-use brake-specific emissions of NOx and CO2 data were collected using the West Virginia University's Mobile Emissions Measurement System (MEMS). An uncertainty analysis was performed on the MEMS and it was …
