Abstract
A method for heating fuel upon start-up of a hybrid vehicle combustion engine, in which method temperature of fuel and temperature outside the vehicle are compared against a first threshold below which starting of the vehicle is forbidden, and against a second threshold higher than the first threshold and above which the engine will start without the fuel being heated. The fuel is heated by exchange of heat with a cooling circuit for the vehicle battery when the external temperature is between the two thresholds.
