brake power. All types of measurements of procedure parameters such as pressure,
temperature, water flow and fuel-used were measured with well calibrated instruments and sensors and then performance results were generated for all blends. The
exhaust gas quality was measured with AVL gas analyzer. At the end, the performance and exhaust gas quality of biodiesel and its blends including plastic pyrolysis
oil blends were studied in comparison with pure diesel fuel. Lastly, the exhaust gas
recirculation (EGR) was performed for B10 (Plastic) as higher amount of NO x in the
exhaust was observed.
3 Results and Discussion
3.1 Brake Thermal Efficiency
For all the blends, brake thermal efficiency increases with increase in brake power.
For a particular brake power, higher the efficiency, lower fuel will be used to generate
the same power. Here B0 outstands all the blends in terms of brake thermal efficiency.
