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.
Claims10
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 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 branch (122) and at least one fuel heating device (13) provided with a heating chamber (131), said heating device (13) being placed adjacent to the fuel injecting device;
- 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 electronic control device (2) and associated with at least one fuel heater (13);
- said system being characterized in that it comprises at least one temperature sensor (4) subsequently mechanically associated with the fuel heating device (13) relative to the fuel flow and electrically associated with the electronic control device (2).

A method for managing the temperature of fuel injected into internal combustion engines, being provided with:
- at least one fuel transporting line (11);
- at least one fuel distribution system (12) associated with the 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 branch (122) and at least one fuel heating device (13) provided with a heating chamber (131), said heating device (13) being placed adjacent to the fuel injecting device;
- 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 electronic control device (2) and associated with at least one fuel heater (13);
- characterized in that the method comprises the steps of:
- measuring the fuel temperature downstream of the heating device (13) by means of a temperature sensor (4) associated with the fuel heating device (13);
- reading a target fuel temperature downstream of the heating device (13) previously inserted and stored;
- processing the signal referring to the fuel temperature;
- and
- performing an action.
