metal surfaces for diesel compared to ecofuel. Adhesive wear was identified on the
sliding surfaces due to the greater wear debris particle size, as discussed above.
The surface damage was identified to be more than 20μm. The ecofuel blend exhibits
smaller worn surfaces compared to diesel. In addition, few fractures and cracks were
identified for ecofuel, but lubricating film protected the smooth surface, which was
