ABSTRACT:
The invention relates to a method for determining the degree of cooling during non-operation of an internal combustion engine. Fuel temperature characteristics at and following an engine start are determined, and the degree of cooling during non-operation of the engine is determined based at least partly on the fuel temperature characteristics. Preferably, the determination of fuel temperature characteristics comprises determining the fuel temperature at the engine at a first point in time and determining the fuel temperature at the engine at a second point in time, the second point in time following the first point in time and following a start of the engine.
