| Popis: | Waste cooking oil biodiesel is considered a common way to generate clean energy in all countries. It can be used efficiently, like fossil fuel quality. To overcome the problem of poor combustion, an increase in the NOx and unburned hydrocarbon emissions, liquid, or solid additives were commonly used to improve combustion and emissions properties. In this study, the Cyclohexane (C6H12) as volatile organic and the flammable liquid compound has been applied as a micro additive for B60D40 fuel blends. Its effect on diesel engine combustion, performance, and emissions has been experimentally investigated. The C6H12 added into the diesel/biodiesel blends at different concentrations of 5, 10, and 15 % by volume basis. Two values of injection pressure have tested experimentally at different Cyclohexane concentrations. The experiment activity changed the fuel injection pressure of 150 and 250 bar, respectively, while the WCOB blends of B60D35c5, B60D30c10, and B60D25c15 have been used. The obtained results have been compared with the commercial diesel#1 and B60D40 fuel blends, respectively. The measured data show that the Cyclohexane additives dramatically improve engine emissions as well as engine performance. The CO, HC, and smoke density have decreased by increasing the Cyclohexane dose as a flammable additive. The NOx emission was reduced by increasing the C6H12 due to the fast combustion process and enhancing the premixed combustion period. Moreover, the increased injection pressure from 150 bars to 250 bars reduces the engine BSFC, HC, CO, NOx, smoke density, increasing engine BTE, CO2 emissions, and exhaust gas temperature. |
