Abstract

Progressive rising of conventional fuel prices, as well as the high strengthened necessities of the environmental norms to reduce the atmospheric pollution levels, are flattering great challenges to scientists and researchers all over the world. In this regard, biofuels have become one of the best alternative fuels for conventional IC engine operation with reduced emissions and improved performance. Goal of paper is to study the influence on emissions and performance variables in one cylinder CI engine fueled accompanied by diesel-waste cooking oil mixtures. The test rig was operated at rated speed 1500 rpm, CR 17.5 and at variable injection operating pressure of 200, 225 and 250 bar correspondingly. Different fuel mixtures of diesel-waste cooking oil i.e., B10, B20 and B30 on mass basis were used for this study. As compared to neat diesel at standard Injection Operating Pressure (IOP) 200 bar, increased IOP 225 bar exhibits utmost BTE, nominal quantity BSFC, minimum CO and HC pollutions with the superior concentration of NOx emissions. In contrast, by using WCO blends, the performance of the engine reduced along with the emissions except HC.
