A comparative study of almond biodiesel-diesel blends for diesel engine in terms of performance and emissions.

Abu-Hamdeh NH, Alnefaie KA - Biomed Res Int (2015)

Bottom Line: A blend of almond biodiesel with diesel fuel gradually reduced the engine CO and total particulate emissions compared to diesel fuel alone.This reduction increased with more almond biodiesel blended into the fuel.Finally, a slight increase in engine NO x using blends of almond biodiesel was measured.

ABSTRACT
This paper investigates the opportunity of using almond oil as a renewable and alternative fuel source. Different fuel blends containing 10, 30, and 50% almond biodiesel (B10, B30, and B50) with diesel fuel (B0) were prepared and the influence of these blends on emissions and some performance parameters under various load conditions were inspected using a diesel engine. Measured engine performance parameters have generally shown a slight increase in exhaust gas temperature and in brake specific fuel consumption and a slight decrease in brake thermal efficiency. Gases investigated were carbon monoxide (CO) and oxides of nitrogen (NOx). Furthermore, the concentration of the total particulate and the unburned fuel emissions in the exhaust gas were tested. A blend of almond biodiesel with diesel fuel gradually reduced the engine CO and total particulate emissions compared to diesel fuel alone. This reduction increased with more almond biodiesel blended into the fuel. Finally, a slight increase in engine NO x using blends of almond biodiesel was measured.

Mentions: Experimental investigations of almond biodiesel on single-cylinder diesel engine were done and several parameters, such as specific fuel consumption (bsfc), brake thermal efficiency (ηb), exhaust gas temperature (Tg), carbon monoxide (CO), nitrous oxide (NOx), particulate matter, and unburned fuel emissions, have been determined. The results obtained are shown in Figures 2through 8.
