+ BSPC x LHV
MDO
BSFC data are quoted for fuel of lower calorific value 42.7 MJ/kg
All other reference conditions refer to ISO standard (ISO 3046-1)
For BSFC and BSEC the following tolerances are to be taken into account:
+5 % for 100-85 % engine power
+6 % for < 85-65% engine power
+7 % for < 65-50% engine power
