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.
Highlights
Owing to glut utilization of petroleum-based fuels for automobile and manufacturing relevance in contemporary time, the world is incrusting severe complications like environmental contamination, global energy crisis and global warming
Based on analysis on performance and emission variables of single cylinder CI engine using WCO blended with conventional diesel, the following Judgments are furnished
Brake Thermal Efficiency (BTE) raised by 7.61% when Injection Operating Pressure (IOP) increased from 200 to 225bar and decreased by 4.86% when IOP increased from 225 to 250 bar
Summary
Owing to glut utilization of petroleum-based fuels for automobile and manufacturing relevance in contemporary time, the world is incrusting severe complications like environmental contamination, global energy crisis and global warming. WCO finds similar as diesel engine fuel because of its ease of use and have striking features equivalent to diesel (Lin et al, 2011). The use of less-cost WCO biodiesel over in cost with petroleum products (Chhetri et al, 2008). This leads to chance for WCO to manufacture raw materials (Meng et al, 2008). Number of scientists were illustrated that WCO blend as a substitute to diesel and decreased dangerous exhaust pollutions along with comparable increase in presentation (Valente et al, 2012). Lapuerta et al (2008) considered dual dissimilar WCO blends and compared diesel in DICI engine.
