Abstract

This paper evaluates and quantifies the environmental impact from the use of some renewable fuels and Fossils fuels in internal combustion engines. The following fuels are evaluated: gasoline blended with anhydrous ethyl alcohol (anhydrous ethanol), conventional diesel fuel, biodiesel in pure form and Blended with diesel fuel, and natural gas. For the case of biodiesel, its complete life cycle and the closed Carbon cycle (photosynthesis) were considered. This study reports the effects of engine load and biodiesel percentage on the performance of a diesel engine fuelled with diesel-biodiesel blends by experiments and a new theoretical model based on the finite-time thermodynamics (FTT). In recent years, biodiesel utilization in diesel engines has been popular due to depletion of petroleum-based diesel fuel. In this study, performance of a single cylinder, four-stroke, direct injection (DI) diesel engine fuelled with diesel-biodiesel mixtures has been experimentally and theoretically investigated. The ecological efficiency concept depends on the environmental impact caused by CO2, SO2, NOx and particulate material (PM) emissions. The resultant pollution of each one of the mentioned fuels are analysed, considering separately CO2, SO2, NOx and particulate material(PM) emissions. The ecological efficiency for pure biodiesel (B100) is 86.75%; for biodiesel blended with conventional diesel fuel (B20, 20% biodiesel and 80% diesel), it is 78.79%. Finally, the ecological efficiency for conventional diesel, when used in engines, is 77.34%; for gasoline, it is 82.52%, and for natural gas, it is 91.95%. All these figures considered a thermal efficiency of 30% for the internal combustion engine.
