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.

11. A method for heating fuel upon start-up of a vehicle combustion engine, the method comprising:
-
comparing temperature of fuel and temperature outside the vehicle against a first threshold beneath which the vehicle is prevented from starting up, and against a second threshold higher than the first threshold and above which the engine is started without the fuel being heated; and heating the fuel by heat exchange with a cooling circuit of the battery of the vehicle when the outside temperature is between the two thresholds. - View Dependent Claims (12, 13, 14, 15)

16. A fuel heating device between a fuel tank and a combustion engine of a vehicle having a fuel temperature sensor and an outside temperature sensor,
wherein fuel is heated by passing through a heat exchanger traversed by a cooling water circuit of a battery of the vehicle.
