Measurement of ultra-fine particles in the exhaust gas of diesel engines fuelled with biodiesel
Measurements of exhaust gas were carried out for a heavy-duty engine using four different fuels: biodiesel (B100); fossil diesel fuel; Shell V-Power® diesel fuel; and a blend of Aral Ultimate® diesel fuel with 5% biodiesel. The aim of the underlying research project – entitled “Measurement of ultra-fine particles in the exhaust gas of diesel engines fuelled with biodiesel” – was to examine in detail the increase in ultra-fine particles that is observed when biodiesel is used instead of fossil diesel fuel. An assessment of the risks of exposure to ultrafine particles was expected as the outcome of the research.
As a result of the project one can draw the conclusion that biodiesel does not lead to an increased emission of ultra-fine particles.
