Claims5
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 steps of:
- (a) measuring a coolant temperature or an ambient temperature of the vehicle;
- (b) driving the fuel pump for a first predetermined operation time;
- (c) activating a heater in the injector to preheat the injector for a second predetermined operation time that is determined depending on the coolant temperature or the ambient temperature;
- (d) stopping fuel supply by stopping driving of the fuel pump when the first predetermined operation time elapses;
- (e) stopping the heater when the second predetermined operation time elapses;
- (f) after the step (e), predicting an intention of a driver to start-up the engine of the vehicle based on a predetermined start-up precondition;
- and
