Metal-containing fuel additives catalyzing soot combustion in diesel particle filters are used in a widespread manner, and with the growing popularity of diesel vehicles, their application is expected to increase in the near future. Detailed investigation into how such additives affect exhaust toxicity is therefore necessary and has to be performed before epidemiological evidence points towards...

Biodiesel is a fatty acid alkyl ester which is renewable, biodegradable and non-toxic fuel which can be derived from any vegetable oil and animal fats. Vegetable oils and animal fats in their raw form have high viscosity that makes them unsuitable as fuels for diesel engines. Transesterification is one of the well-known process by which fats and oils are converted into biodiesel. The reaction o...

This study discusses the suitability of iso-butanol/diesel fuel blends as an alternative fuel and determines their effects on the performance and combustion characteristics of a heavy-duty diesel engine. For this purpose, various isobutanol/diesel fuel blends containing 5%, 10% and 15% iso-butanol were prepared in volume basis and tested in a turbo-charged, six-cylinder direct injection diesel ...

In this paper, the control scheme of a Liquefied Petroleum Gas (LPG)–diesel dual-fuel engine with electronic control is illustrated, the external characteristics and load characteristics of the LPG– diesel dual-fuel engine and the diesel engine are compared and analyzed. The experimental results show that, compared with diesel, the output performance of dual fuel is not reduced, while smoke emi...

The emission of solid carbonaceous particulate matter (i.e. soot) is a world-wide problem that effects both human health and global environmental health alike. Although a number of sources contribute to the concentration of soot in the atmosphere, Diesel engines play a significant role. Diesel engines, or direct-injection compression-ignition engines, are the primary power plant for delivering ...

Bio-diesels and their blends are proven alternative fuels for petroleum diesel. But still the research work is going, on the bio-diesels application to make it environmental friendly. Particulate matter and oxides of nitrogen are the main pollutants in the tail pipe emissions of bio-diesel fueled engine. In this paper, mahuva methyl ester along with diethyl ether (DEE) used as fuel for the sing...

The objective of this work was to study the formation of particles and their morphology and chemical composition in large-scale diesel engines operating with low-grade residual fuel oils. The effect of a Mg-based fuel oil additive on exhaust gas particles was also investigated. Particle characteristics were determined by means of the methods of aerosol technology, chemical analyses, and electro...

This paper represents the prospect of mustard oil as a renewable and alternative fuel. To cope up with present load-shedding situation and to reduce the dependency on imported fuel, Bangladesh government is encouraging the use of renewable energy sources. Since diesel engines have versatile uses including small irrigation pumping systems, and standby small electricity generators, use of diesel ...

Increased energy demand and the concern about environment friendly technology, renewable bio-fuels are better alternative to petroleum products. In the present study linseed oil was used as alternative source for diesel engine fuel and the results were compared with baseline data of neat diesel. Performance parameters such as brake thermal efficiency (BTE) and brake specific fuel consumption (B...
