Download or read book Performance Combustion Characteristics and Exhaust Emission of a Direct Injection Diesel Engine Using Water Oil Emulsions as Fuel written by E. M. Afify and published by . This book was released on 1985 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: A CLR single cylinder diesel engine is used to determine the effect of air content in the emulsified fuel on the performance, exhaust emissions and ignition delay of diesel engines. The experiments were conducted using diesel fuel no. 2 and JP-4 as baseline fuels and emulsions containing 15%, 30% and 45% water by volume. The air charge temperature was varied from 88 F to 302 F. The effects associated with use of the emulsions on performance, ignition delay and exhaust emissions were determined by making detailed measurements of fuel consumption, engine operating parameters and exhaust emissions. The results showed that slight improvement in Brake Specific Fuel Consumption (BSFC) was observed when emulsions with low water content were used at high speeds. For high water content emulsions, the BSFC increased. Heating the intake air increased the BSFC at high engine loads and slightly improved it at low engine loads. While the ignition delay was found to increase with the increase of the water percentage in the emulsion, preheating the air charge was effective in reducing it. Although, NO sub x and soot formation were reduced effectively with the increase of water content in the emulsion, preheating the air charge adversely affected NO sub x and soot emissions. While CO and VHC emissions increased with the increase of the water content in the emulsion, increasing the intake air temperature slightly reduced carbon monoxide and unburned hydrocarbons at low loads. Keywords: Combustion; Exhaust emissions; Water/Oil emulsions.

Download or read book Experimental Evaluation of Oxygen enriched Air and Emulsified Fuels in a Single cylinder Diesel Engine written by and published by . This book was released on 1991 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of a single-cylinder, direct-injection diesel engine was measured with intake oxygen levels of up to 35% and fuel water contents of up to 20%. Because a previous study indicated that the use of a less-expensive fuel would be more economical, two series of tests with No. 4 diesel fuel and No. 2 diesel fuel were conducted. To control the emissions of nitrogen oxides (NO(subscript x)), water was introduced into the combustion process in the form of water-emulsified fuel, or the fuel injection timing was retarded. In the first series of tests, compressed oxygen was used; in the second series of tests, a hollow-tube membrane was used. Steady-state engine performance and emissions data were obtained. Test results indicated a large increase in engine power density, a slight improvement in thermal efficiency, and significant reductions in smoke and particulate-matter emissions. Although NO(subscript x) emissions increased, they could be controlled by introducing water and retarding the injection timing. The results further indicated that thermal efficiency is slightly increased when moderately water-emulsified fuels are used, because a greater portion of the fuel energy is released earlier in the combustion process. Oxygen-enriched air reduced the ignition delay and caused the heat-release rate and cumulative heat-release rates to change measurably. Even at higher oxygen levels, NO(subscript x) emissions decreased rapidly when the timing was retarded, and the amount of smoke and the level of particulate-matter emissions did not significantly increase. The single-cylinder engine tests confirmed the results of an earlier technical assessment and further indicated a need for a low-pressure-drop membrane specifically designed for oxygen enrichment.

This book was released on 2008 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
