“…Comparing the ternary fuel samples with the binary and DF samples, it was noted that significantly lower THC concentrations were generated for the mineral fuel under the tested loads at both engine speeds. Furthermore, it was found that the significantly higher THC emissions were generated at low-load regime for all tested samples, at both engine speeds, which is consistent with the results obtained by Murugan et al [21] and Bhaskar et al [47]. The above authors explained that the higher THC emissions observed at low loads resulted from incomplete combustion, caused by the production of locally over-lean mixtures during the longer ignition delay period.…”

Biofuels are one of the short-term alternatives for reducing the well-to-wheel greenhouse gas footprint of transport. In the framework of compression-ignition engine fuels. This study investigates the feasibility of using cold-pressed rapeseed oil as a biocomponent, admixed with distilled tyre pyrolytic oil, as an energy-efficient alternative to commonly considered methyl ester-based mixtures in diesel fuel. Selected ternary and binary fuel blends are subjected to engine tests. Their scope covers 80% of the engine map and aims at identifying tradeoffs between fuel composition, engine performance and emissions. The results show that fuel mixtures containing a large fraction of rapeseed oil (up to 55% by volume) can be effectively combusted when pyrolytic oil distillate is introduced as the additive. The deterioration in brake efficiency for such fuel does not exceed 1.2% with respect to diesel baseline. At the same time, the results are superior in terms of both efficiency and emissions when compared to FAME-based biodiesel. Finally, with indicated efficiencies on a similar level as the diesel baseline, suggesting improved burning rate with pyrolytic oil addition, the study identifies parasitic losses in fuel injection equipment as a significant contributor to the overall efficiency penalty for the examined ternary mixtures.
