Investigation of the influence of emulsion quality on HC-emission of Diesel engines Final report / Untersuchung des Einf...
By lowering the local temperature in the burning gas and by controlling the local air/fuel ratio by means of water addition to the fuel and injection into the combustion chamber in the form of a diesel/water emulsion, an NO_x decrease as well as reductions in black smoke emissions can be achieved. Since, at least lower loads and speeds this results...
Development of an NO_x poor Diesel engine of a small capacity through primary measures / Entwicklung eines NO_x-armen Di...
With the further development of the long-life Diesel engine developed by the company Fichtel and Sachs for series produced internal combustion engine driven heat pumps of a small heating capacity, a low-NO_x combustion engine for plants of useful energy utilization is to be created through primary measures. The general objective of NO_x-emissions o...
Determination of the combustion process and its scattering range in the Otto engine at a high air ratio using pressure c...
This final report to the FVV research project 'Combustion sensor technology in lean-fuel operation' covers the selection of the best number and positioning of sensors, the variation of operating point and fuel, the characteristics of sensor signals and the scattering of sensor signals based on a stabilization of operation at a high air ratio. (orig...

Reduction of exhaust emissions of heavy commercial vehicles. Project section: Low emission city bus engine Final report ...
In line with the project, a stationary natural gas engine was revamped and adjusted as a liquified gas operated engine for commercial vehicles. The testing of the whole system was successful, the measurement with reference to Directive 88/77/EEC gave the following values: CO: 0,3 g/kWh; HC: 0,2 g/kWh; NOx: 0,8 g/kWh. (orig./HW) / Im Rahmen des Vorh...
Emission reduction of high-efficiency gas turbines by means of purposeful combustion control Final report / Schadstoffre...
In dem vorliegenden Abschlussbericht werden die erzielten Ergebnisse zweier trockener Verbrennungskonzepte, die auf eine Reduktion der NO_x-Emission zielen, dargestellt und diskutiert. Es handelt sich um die Fett-Mager- und die Magerverbrennung mit Vorverdampfung und Vorvermischung des fluessigen Brennstoffs. Darueberhinaus werden Auslegungskriteri...
Combustion analysis in turbulent and laminar flames by narrow-bandwidth excimer lasers / Verbrennungsanalyse in turbulen...
Mit zweidimensionalen Messmethoden auf der Basis schmalbandiger Excimerlaser werden verschiedene Flammen untersucht. Die grosse spektrale Helligkeit im Wellenlaengenbereich von ultraviolettem Licht, durch die sich die verwendeten Laser auszeichnen, ermoeglicht die Anwendung unterschiedlicher laserdiagnostischer Techniken. Mit planarer laserinduzier...
Investigation of the hydrocarbon concentration in the vapour space of underground storage tanks for gasoline / Untersuch...
The aim of this work was a thorough investigation of the hydrocarbon concentration of the gaseous atmosphere in an underground storage tank for gasoline with respect to explosion protection problems. Operational parameters like e.g. the draw out-rate of liquid as well as geometric characteristics like e.g. the diameter of the vent opening have been...
