FUEL HEATING DEVICE FOR IMPROVING COLD START PERFORMANCE OF FLEX FUEL VEHICLE

摘要

A fuel heating device may improve cold start performance and solve a number of problems of conventional auxiliary tank and heating systems of a flex fuel vehicle (FFV). The fuel heating device may include a heater having embedded therein a heat emission object for heating fuel, a solenoid valve connected the heater such that a flow path to a first outlet is opened or closed to selectively supply fuel, a temperature sensor installed in the heater, and a controller for turning on and off the heater and opening and closing the solenoid valve according to a temperature of the fuel, in which 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 the fuel tank.
