An Experimental Study on Performance and Emissions of a Single Cylinder Direct Injection Diesel Engine with crambe abyssinica and crambe orientalis biodiesels

Abstract

As an alternative fuel of diesel engines, the interest in biodiesel fuels is rising due to some useful features. This interest leads to an increase in the diversity of studies. In recent years, studies about the crops that can grow in non-arable lands and produce nonedible oils were increased. In this work, performance and emissions of biodiesel production from crambe abyssinica and crambe orientalis oils were studied. The purpose of this paper was to examine the performance and emissions of crambe biodiesels and diesel fuel in a single-cylinder, four-stroke, direct injected diesel engine with air cooling system at 2200 1/min fixed engine speed and with four different engine loads (BMEP, 0.12 MPa, 0.24 MPa, 0.36 MPa and 0.48 MPa). Crambe abyssinica biodiesel and crambe orientalis biodiesel were expressed as CAME B100 and COME B100 respectively. The brake specific fuel consumption (BSFC), carbon monoxide (CO), carbon dioxide (CO₂), total hydrocarbon (THC), nitrogen oxide (NOx) and smoke emissions results obtained from the experimental study were compared with No. 2 diesel fuel. Achieved results suggest us that crambe biodiesels can preferred for diesel engines. Since environmental effects and energy requirement become more important, the interest of the crops that can grow unsuitable lands has increased.
