Abstract:
1. A fuel heating device for improving cold start performance of a flex fuel vehicle (FFV), the fuel heating device comprising: a heater having an inlet and an outlet for allowing introduction, passage, and discharge of a fuel through the heater, the heater having embedded therein a heat emission object for heating the fuel; a solenoid valve having a first outlet which is connected to the inlet of the heater such that a flow path to the first outlet is opened or closed to selectively supply the fuel to the inlet; a temperature sensor installed in the heater to detect a temperature of the fuel within the heater; and a controller for turning on and off of the heater and opening and closing of the solenoid valve according to the temperature of the fuel detected by the temperature sensor; wherein the outlet of the heater is connected with a cold start injector through a cold start line and an inlet of the solenoid valve is connected with a fuel line connected from a fuel tank, and a second outlet of the solenoid value is connected to a main line connected to a main injector, and wherein ,through control of the solenoid valve, a first fuel path to the heater and the cold start line connected to the cold start injector or a second fuel path to the main line connected to the main injector is selectively formed.
