The article discusses the possibility of using glycerol as an additive to engine fuel in order reduce tendency combustion knock, and thus increase octane number a given fuel. Experimental tests were carried out on UIT-85 research with variable compression ratio from eight eleven test intensity knock. completely renewable fuel—the blend butanol 25 75%, respectively—was tested. A comparative anal...

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 ...

Abstract A series of sulfated aluminum oxides (S-Al 2 O 3 ), investigated as an electrolyte additive in Nafion membranes, was synthesized via three different methods: (i) sol–gel sulfation starting from alkoxide precursor, (ii) room temperature fumed oxide, and (iii) hydrothermal oxide. Through the characterization S-Al by means X-ray diffraction (XRD), thermogravimetric analysis (TGA), infrare...

Bioadditives are elements derived from plants that used as additives to improve fuel quality. Citronella oil is one type of essential has been studied for its potential a bio additive because volatility and ability dissolve into fuel. The purpose using this bioadditive increase engine performance. This research was conducted an experimental method, some the samples tested consisted pertalite fu...

Currently, the global issue for countries is search raw materials and production of bioenergy within their country; also includes biodiesel fuels. One most promising fuels green diesel fuel produced by hydrogenation vegetable oils. Three methods have been proposed to obtain high-quality environmentally friendly fuel: compounding with hydro-treated fuel, compositions improved «green diesel» bio-...
