Effect of Exhaust Gas Recirculation on Performance and Emissions of a Modern Small Diesel Engine Fueled with Biodiesel-Kerosene Blends
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 3
Abstract
The objective of this paper is to evaluate the effects of biodiesel blends with kerosene, with exhaust gas recirculation (EGR) on a diesel engine, and to compare performance and emission results with that of conventional diesel fuel. In this experimental work, six fuels: biodiesel (B100); diesel (D100); kerosene (K100); biodiesel 20% and kerosene 80% by vol. (B20 K80); biodiesel 50% and kerosene 50% (B50 K50); and biodiesel 80% and kerosene 20% (B80 K20) were investigated with and without EGR system. Biodiesel, produced from canola oil through a transesterification process, was used to examine the performance and emissions of a HATZ 2G40 2-cylinder, air-cooled, direct-injection (DI) diesel engine. All blends were tested at three different engine speeds (1000 rpm, 2100 rpm and 3000 rpm) and at each speed three loads, such as low load (≈20%), medium load (≈50%) and high load (≈80%) were applied. The effects of the blends on carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbon (HC), and smoke emissions, as well as on the performance parameter of the engine, such as brake thermal efficiency (BTE), and brake-specific energy consumption (BSEC) were examined. It was observed that the EGR technique is very effective to reduce exhaust gas temperature; hence it’s potential to decrease NOx formation without affecting engine performance.
