The aim of this work was to study the combustion, performance, and emission characteristics of a 5.5 kW four-stroke single-cylinder water-cooled direct-injection diesel engine operated with blends of biodiesel-like fuel (BLF15, BLF20 & BLF25) obtained from a 50:50 mixture of transesterified waste transformer oil (TWTO) and waste canola oil methyl esters (WCOME) with petroleum diesel. The mixtur...

As the production process continues to be refined, biomass pyrolysis oils are increasingly being considered as potentially feasible renewable fuels. Combustion of pyrolysis oils in diesel engines has been scarcely studied, and the few studies which have been performed indicate that these fuels exhibit excessively long ignition delay, rendering them dependant on auxiliary ignition sources for di...

Biodiesel as a clean energy source could reduce environmental pollution compared to fossil fuel, so it is becoming increasingly important. In this study, we investigated the effects of different pilot injection timings from before top dead center (BTDC) and exhaust gas recirculation (EGR) on combustion, engine performance, and exhaust emission characteristics in a common rail diesel engine fuel...

At the previous conference KONES’2004 emission characteristics of C.I. engine fuelled with either rape oil methyl ester (RME) or diesel fuel (DF) as a main fuel and ethanol as additional fuel were presented. Comparison of emission and brake fuel conversion efficiency (BFCF) of the engine fuelled with both main fuels showed that fuelling with RME and ethanol is more advantageous on account of bo...

In this study, the biodiesel produced from cottonseed oil was prepared by a method of Transesterification and its blends of 25%, 50%, 75% and 100% in volume, and standard diesel fuel separately. The effects of biodiesel addition to diesel fuel on the performance, emissions and combustion characteristics of a naturally aspirated DI compression ignition engine were examined. Biodiesel has differe...

Tests have been carried out to evaluate the performance, emission, and combustion characteristics of a single cylinder direct injection diesel engine fueled with 10%, 30%, and 50% of tyre pyrolysis oil (TPO) blended with diesel fuel (DF). The TPO was derived from waste automobile tyres through vacuum pyrolysis. The combustion parameters such as heat release rate, cylinder peak pressure, and max...

Introduction The present day oil crisis and need for more fuel economy has driven the demand for diesel powered automobiles. Diesel soot is one of the primary emissions of diesel combustion and accurate modeling of soot formation is a challenging area for combustion researchers. The soot formation in diesel engine combustion has been previously modeled using a twostep phenomenological model whi...

solidified samples of fuel oil combustion bottom ash with two sets of ordinary portland cement (opc) and pozzolan added opc were investigated with three sets of chemical leaching tests. toxicity characteristic leaching test (tclp) results classified waste material and its solidification products as hazardous. although ni and cr have over-leached, but their close examination with sequential chem...
