WebThe formula for calculating the CCAI is where D is the density in kg/m 3 at 15°C, V the viscosity in cSt (mm 2 /s) at T°C; and t the temperature at which V is determined. The … Webfuel grades suitable for a given engine type and fuel treatment plant. This edition of Fuel Recommendations specifies four grades of distillate fuel, one of which is for diesel engines for emergency purposes. It also specifies ten grades of residual fuel. Requirements for gas turbine fuels used in marine applications are specified in ISO 4261.
