Correction to: Journal of Thermal Analysis and Calorimetry https://doi.org/10.1007/s10973-019-09055-1

In the original publication of the article, Figs. 6 and 7 were published incorrectly without test fuel D80/nb20+BG (0.5 kg h⁻¹). The corrected Figs. 6 and 7 along with corrected test values are given in this correction.

As shown in the Fig. 6, the peak cylinder gas pressure for conventional diesel was around 53 bar, and for dual fuel operational mode, it was 53.56, 54.05, 54.51, 54.74, 55.88 and 56.89 bar for D90/nb10 + BG 0.5 kg h⁻¹, D90/nb10 + BG 1.2 kg h⁻¹, D90/nb10 + BG 2 kg h⁻¹, D80/nb20 + BG 0.5 kg h⁻¹, D80/nb20 + BG 1.2 kg h⁻¹ and D80/nb20 +BG 2 kg h⁻¹, respectively.

As illustrated in Fig. 7, the maximum net heat release rate for conventional diesel was estimated to be 42.25 J/°CA when compared to 43.09, 44.16, 45.28, 45.67, 46.48 and 47.88 J °CA⁻¹ for D90nb10 + BG 0.5 kg h⁻¹, D90nb10 + BG 1.2 kg h⁻¹, D90nb10 + BG 2 kg h⁻¹, D80/nb20 + BG 0.5 kg h⁻¹, D80/nb20 + BG 1.2 kg h⁻¹ and D80/nb20 + BG 2 kg h⁻¹, respectively, at full engine operating load.
