We investigated the performance of a mix of two emerging biofuels, butanol and hydrotreated vegetable oil (HVO), in an Iveco Tector diesel engine. HVO, a possible drop-in fuel for diesel engines features excellent combustion and emissions characteristics. All biofuels exhibited, relative to diesel fuel, a decrease in the concentration of particulate PAHs and n-alkanes in emissions, while the concentrations of hopanes and steranes originated from lubricating oil were comparable across all fuels. Cold starts yielded about 15% higher concentrations of both particulate matter and particulate organic compounds in emissions than hot starts.
