Abstract

Exemplary embodiments include a method for analysis of fuel supplied to a combustion engine during operation of the engine. The method can include obtaining respective indications of a temperature of the fuel supplied to the engine and a density of the fuel supplied to the engine; deriving a temperature-adjusted fuel density based on the indicated density of fuel in dependence of relationship between the indicated temperature of the fuel and a predefined reference temperature; and deriving, based at least on the temperature-adjusted fuel density, a heating value that is descriptive of the amount of heat released during combustion of a predefined amount of the fuel.
