Experimental Investigation of Performance and Exhaust Emissions of a Diesel Engine With Scrap Tires Rubber Oil Blended Diesel Fuel
AbstractUsing of scrap tires will result in recycle the waste of rubber products and solve the problem of increasing the prices of mineral fuel. Different blends of scrap tires rubber oil (STRO) and diesel fuel have been investigated experimentally using diesel engine for performance and emission products. A blend of 10, 20, 30, 40% and standard diesel fuel have been tested in the diesel engine and the results showed a good improvement in reducing the pollutants. One of the important problems facing the mixed with fuel oil is to increase the viscosity and decreasing volatility that lead to carbon deposition and ring sticking of these types of oils. When blended with diesel, (STRO) presented lower viscosity, improved volatility, better combustion and less carbon deposit. NOx emission for the blend of 20% scrap tires rubber oil (STRO 20) was reduced by 40%. An increase in emission of hydrocarbon by 20% was found at full load. The emissions of carbon monoxide (CO) from scrap tires rubber oil and its blends were higher except in (STRO 20) blend that reduced by 15%. The brake thermal efficiency was spotted higher with standard fuel than scrap tire rubber oil and its blends. The present work showed that the 20% blending ratio is the optimum blending ratio for scrap tires rubber oil depending on experimental test results. Also, the current study introduce the waste of rubber products as a good alternative fuel blended with diesel fuel verify economical and environmental benefits.
