## Buildings.Fluid.Data.Fuels

Package with properties of fuels

### Information

Package with records for fuel properties. Note that the heating value and the mass density can vary for individual fuels. The parameter `mCO2` are the CO2 emission in kilograms that are released per kilogram fuel that is burnt.

Extends from Modelica.Icons.MaterialPropertiesPackage (Icon for package containing property classes).
