Abstract
Diesel fuel exhaust, produced in an internal combustion engine, also contains particulate matter. Its composition differs based on the type of fuel, its consumption rate, and the mode of engine operation. International Agency for Research on Cancer (IARC) has classified diesel exhaust as a carcinogenic, inhaling which can cause lung cancer. A standard wall-flow filtration device like diesel particulate filter (DPF) is used to remove particulate matter or soot from diesel exhaust. With BS-VI emission norms, the emission standards have become stricter and thus an attempt is made to compare the microstructure and amount of soot produced by diesel and a biodiesel blend. The use of biodiesel is increasing continuously since it has lower net CO2 emission, and the EU demands the use of renewable sources in the transport sector. It has been found, by weighing the respective DPFs, that engine running with biodiesel blends is producing less soot. Size of soot particles affects its reactivity during filter regeneration. Soot trapped is analyzed under a scanning electron microscope (SEM) to observe its structure and density. EDX analysis revealed the presence of zinc in low concentration in biodiesel soot. This also indicates uniform blending of biodiesel.
