Abstract

Official abstract text for this publication.

A control method of the heated injector system for a vehicle including an injector, injecting fuel into an engine of the vehicle, and a fuel pump supplying the fuel to the injector, includes activating a heater to preheat the injector, stopping fuel supply by stopping driving of the fuel pump, and upon stopping the fuel supply, re-activating the heater to heat the injector.

First claim

Opening claim text (preview).

What is claimed is: 1 . A control method for a heated injector system for a vehicle having an injector, injecting fuel into an engine of the vehicle, and a fuel pump supplying the fuel to the injector, the method comprising: activating a heater to preheat the injector; stopping fuel supply by stopping driving of the fuel pump; and upon stopping the fuel supply, re-activating the heater to heat the injector. 2 . The control method according to claim 1 , further comprising: driving the fuel pump simultaneously with or after the preheating. 3 . The control method according to claim 2 , wherein the preheating and driving the fuel pump are terminated when a predetermined operation time elapses. 4 . The control method according to claim 2 , wherein the preheating and driving the fuel pump are terminated when a pressure of the fuel satisfies a predetermined pressure. 5 . The control method according to claim 2 , wherein a duration time of the preheating is determined so as to be longer than that of the fuel pump driving. 6 . The control method according to claim 1 , further comprising: prior to the preheating, measuring a coolant temperature or ambient temperature. 7 . The control method according to claim 6 , wherein the preheating of the injector and the heating of the injector are performed when the measured temperature is equal to or less than a predetermined temperature. 8 . The control method according to claim 1 , further comprising: upon stopping the fuel supply and prior to heating the injector, predicting a cranking of the vehicle. 9 . The control method according to claim 8 , wherein the predicting comprises predicting an intention of a driver to start-up the engine of the vehicle based on a predetermined start-up precondition, and wherein the heating of the injector is performed when the predetermined start-up precondition is satisfied. 10 . The control method according to claim 9 , wherein the start-up precondition includes turning of a key after fastening a safety belt. 11 . The control method according to claim 9 , wherein the start-up precondition includes turning of a key in a state in which a brake is being presses.
