The paper mainly aims at improving the performance and reduction in exhaust emissions of an indirect injection diesel engine fuelled with alternative modern biofuel Pinus Sylvestris oil, which is traditionally oxygenated obtained from resins tree. Its physical chemical properties are similar to regular petro-diesel fuel can be used without transesterification directly engines. On other hand, a ...

The production of the fire suppressant CF3Br has been banned, and finding a replacement with all of its desirable properties is proving difficult. Iron pentacarbonyl has been found to be up to several orders of magnitude more effective than CF3Br, but it is flammable and highly toxic. Ferrocene [Fe(C5H5)2], which is much less toxic and flammable than Fe(CO)5, can also be used to introduce iron ...

Broth (Albimi) containing 2 per cent "M" peptone, 0.1 per cent glucose, 0.2 per cent yeast autolysate, 0.5 per cent NaCl, and 0.01 per cent sodium bisulfite was the medium used. Four and one-half ml of medium were added to each tube, sterilized for 15 min at 15 lb pressure, and the tubes of media, after inoculation, were incubated at 37 C in air or under varying amounts of carbon dioxide. Three...

An imploding annular shock wave driven by a jet of air was used to initiate detonations inside a 76 mm diameter tube. The tube was filled with a test gas composed of either stoichiometric ethylene-oxygen or propane-oxygen diluted with nitrogen. The strength of the imploding shock wave and the sensitivity of the test gas were varied in an effort to find the minimum shock strength required for de...

The potential of Palm Methyl Esters (PME) as an alternative fuel for gas turbines is investigated using a swirl burner. The main air flow is preheated to 623 K and a swirling spray flame is established at atmospheric pressure. The spray combustion characteristics of PME are compared to diesel and Jet-A1 fuel under the same burner power output of 6 kW. Investigation of the fuel atomizing charact...
