Experimental evaluation of advanced combustion modes study on a crdi engine using pode wco diesel fuel blends

Abstract

Several countries across the world have done experiments on the use of biodiesel in common rail direct injection (CRDI) diesel engines. Of all the biodiesels tested so far, Waste Cooking Oil (WCO) biodiesel has been found to be most effective and most promising and preferable due to its lowcost and availability in plenty. Nevertheless, the use of raw WCO biodiesel is hampered by issues such as engine deposits and extremely high viscosity. As a result, it is mixed with diesel in smaller volumes. While WCO biodiesel low volume proportional blends reduce hydrocarbon (HC), Carbonmonooxide (CO), and soot emissions with outstanding combustion characteristics, theyappear to encourage the generation of NOx. The soot-NOx and HC-CO trade-off is now regarded to be a more essential aspect for study due to the strict Bharat Stage-VI requirements. Polyoxymethylene dimethyl ether (PODE), which has a higher cetane number, an increased oxygen content, a lower viscosity and improved combustion characteristics with a favorable soot-NOx and HC-CO trade-off, has been chosen for the current study as a means of resolving this issue. Diesel is mixed with transesterified WCO biodiesel in proportions of 10, 20, 30% and are designated as W10, W20, and W30.. Using ASTM standards, the chemical characteristics of the blended fuels havebeen ascertained. PODE is added to the optimized W20 mixture in variedamounts, such as 10, 20, and 30%, to achieve a good soot-NOx and HC-COtrade-off. The characteristics of the test fuels have been established and more research has been conducted. WCO, WCO biodiesel, and PODE have been analyzed using Gas-Chromatography Mass Spectroscopy, and fuels such as 30% PODE in W20 (W20P30), 20% PODE in W20 (W20P20), 10% PODE in W20 (W20P10), W30, W20, W10, and D100 have been analyzed using Fourier Transform Infrared Spectroscopy. Finally, W20P20 has been found to be optimum in the conventional diesel combustion mode in regard to combustion, emission, and performance characteristics. Still the optimization with respect to soot-NOx and HC-CO trade-off has been found as a major limitation newline
