Book Description
Im vorliegenden Band 3/2008 berichtet Herr Eckert uber die Ergebnisse aus Untersuchungen zur Partikel- und Stickoxidminimierung bei Dieselmotoren durch Wassereinbringung. Das primare Ziel ist dabei die innermotorische Reduzierung der thermischen Stickoxidbildung. Es sind unterschiedliche Methoden der wassereinbringung in den dieselmotorischen Verbrennungsprozess moglich; beispielsweise die Einspritzung von Wasser in das Ansaugsystem, eine direkte Einspritzung von Wasser in den Brennraum sowie die Wassereinbringung mit Diesel- Wasser Emulsionen. Diese Massnahmen sind unter anderem bei dieselmotoren, die zumindest teilweise mit Schwerol betrieben werden, besonders interessant, da dort klassische Methoden zur Schadstoffreduktion, wie z.B. Abgasruckfuhrung oder Abgasnachbehandlung, nur mit erheblichem Aufwand eingesetzt werden konnen.

Book Description
Diesel engine performance during cold starting is very crucial for smooth engine start at undesirable emission level. The development of cold start strategies that improve combustion stability relies mainly on the understanding of the combustion process during the cold starting. Even for modern diesel engines, the conditions during the cold start is far from normal operation characterized by large amount of unburned hydrocarbon emissions and long start to idling time. Thus, the use of an in-cylinder combustion sensor to measure the combustion quality during engine starting can significantly improve engine cold start control strategies. The ion current sensor has the potential to be used as onboard sensor to measure the combustion process during engine operation and can be used as feedback to the engine control unit. The aim of this research is to study and determine the combustion instability and its impact on various combustion and ionization characteristics by performing cycle analysis for a comparison between engine performance using ultra low sulfur diesel (ULSD) and aviation jet propulsion (JP8) fuels during cold start at 25 degrees Celsius. It also shows a comparison between two ion current sensors during low load idling using the same fuels. For this purpose, the glow plug and fuel injector of VW 2.0L turbocharged diesel engine were modified and electrically insulated to be used as ion current sensors. The experimental test was conducted to study the combustion process and emission product produced during low load idling.

Book Description
Combustion technology has traditionally been dominated by air/fuel combustion. However, two developments have increased the significance of oxygen-enhanced combustion-new technologies that produce oxygen less expensively and the increased importance of environmental regulations. Advantages of oxygen-enhanced combustion include less pollutant emissi

Book Description
Diesel-ignited gasoline and diesel-ignited methane dual fuel combustion experiments were performed in a single-cylinder research engine (SCRE), outfitted with a common-rail diesel injection system and a stand-alone engine controller. Gasoline was injected in the intake port using a port-fuel injector, whereas methane was fumigated into the intake manifold. The engine was operated at a constant speed of 1500 rev/min, a constant load of 5.2 bar IMEP, and a constant gasoline/methane energy substitution of 80%. Parameters such as diesel injection timing (SOI), diesel injection pressure, and boost pressure were varied to quantify their impact on engine performance and engineout ISNOx, ISHC, ISCO, and smoke emissions. The change in combustion process from heterogeneous combustion to HCCI like combustion was also observed.
