Abstract
A system and a method of controlling the temperature of fuel injected into combustion engines, which provides a reduced amount of fuel injected into engines propelled with either pure gasoline or ethanol or any bi-fuel mixture by precisely controlling the amount of heat supplied to the fuel.
Claims8
A system for managing the temperature of fuel injected into internal combustion engines, the system including:
- at least one fuel transporting line (11);
- at least one fuel distribution system (12) associated with the at least one fuel transporting line (11) having at least one main duct (121) and at least one branch (122);
- a fuel injecting device (14) associated with the at least one branch (122) and at least one fuel heating device (13) provided within a heating chamber (131), said at least one fuel heating device (13) being placed adjacent to and upstream of an inlet end of the fuel injecting device, the heating chamber (131) configured to receive the fuel therein;
- at least one electronic control device (2) associated with the fuel injecting device (14);
- and at least one fuel heating control device (3) associated with the at least one electronic control device (2) and associated with the at least one fuel heating device (13);
- said system being characterized in that it comprises at least one temperature sensor (4) positioned within the heating chamber (131) and electrically associated with the at least one electronic control device (2);
- wherein the heating chamber (131) is provided with a fuel inlet portion (132) and a fuel outlet portion (133) distal from the fuel inlet portion (132);
- and,
- wherein the fuel inlet portion (132) is placed at a lower region of said heating chamber (131) and the fuel outlet portion (133) is placed at an upper region of said heating chamber (131).

- at least one electronic control device (2) associated with the fuel injecting device (14);
- and at least one fuel heating control device (3) associated with the at least one electronic control device (2) and associated with the at least one fuel heating device (13);
- characterized in that the method comprises the steps of:
- measuring the fuel temperature downstream of the at least one fuel heating device (13) by means of a temperature sensor (4) positioned within the heating chamber (131) and being associated with the at least one fuel heating device (13);
- reading a previously stored target fuel temperature for fuel downstream of the at least one fuel heating device (13);
- processing a signal referring to the measured fuel temperature;
- and
- performing an action.
