CPC F02D 41/3005 (2013.01) [F02M 53/04 (2013.01); F02D 2200/0606 (2013.01)] | 5 Claims |
1. A method of control of fuel temperature injected in a combustion engine having a fuel, the combustion engine comprising:
an engine control unit (9) in the combustion engine,
at least one fuel-heating device (3) positioned in contact with the fuel in a fuel rail (1);
at least one fuel-heating control unit (6) connected by means of at least one data connection to the engine control unit (9), the at least one fuel-heating control unit (6) electrically connected to the at least one fuel-heating device (3), where the at least one fuel-heating control unit (6) controls the operation of the at least one fuel-heating device (3);
the method comprising the successive steps of:
measuring the temperature of the fuel (Tc) downstream of the at least one fuel-heating device (3);
reading a target temperature of the fuel (Ta) downstream of the at least one fuel-heating device (3);
comparing the temperature of the fuel (Tc) downstream of the at least one fuel-healing device (3) with the target temperature of the fuel (Ta) downstream of the at least one fuel-heating device (3);
detecting an input from an acceleration pedal;
calculating a power (Paq) necessary to be used in the at least one fuel-heating device (3) so that the temperature of the fuel (Tc) downstream of the at least one fuel-heating device (3) is maintained during an anticipated variation in a flow rate of the fuel injected in the combustion engine, the anticipated variation in the flow rate being determined based on the input from the acceleration pedal and corresponding to a variation in a speed of the combustion engine;
applying the calculated power (Paq) to the at least one fuel-heating device (3), the application of the calculated power (Paq) controlled by the at least one fuel-heating control unit (6);
comparing the temperature of the fuel (Tc) downstream of the at least one fuel-healing device (3) with the target temperature of the fuel (Ta).
