Abstract
Official abstract text for this publication.
A fuel heating device for a vehicle may include a start sensor detecting a starting of a vehicle; a controller area network (CAN) communication device transmitting and receiving various signals to and from an engine control device; a resistance sensor measuring a resistance of a heater provided inside an injector; and a controller controlling the resistance sensor to measure the resistance of the heater when the starting of the vehicle is detected in a state in which a failure occurs in the CAN communication device, converting the measured resistance of the heater into a temperature of a fuel, and operating the heater to heat the fuel to a reference temperature when the converted temperature is lower than or equal to a threshold.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel heating device for a vehicle, comprising: a start sensor detecting a starting of the vehicle; a controller area network (CAN) communication device performing communication of various signals with an engine control device; a resistance sensor measuring a resistance of a heater provided inside an injector; and a controller controlling the resistance sensor to measure the resistance of the heater when the starting of the vehicle is detected when a failure of the communication occurs in the CAN communication device, converting the measured resistance of the heater into a temperature of a fuel, and operating the heater to heat the fuel to a reference temperature when the converted temperature is lower than or equal to a threshold. 2. The fuel heating device according to claim 1 , wherein the controller operates the heater unless a number of operating the heater when the failure occurs in the CAN communication device exceeds a predetermined value. 3. The fuel heating device according to claim 1 , wherein the fuel heated by the heater is one of ethanol, a fuel mixture of ethanol and gasoline, and gasoline. 4. The fuel heating device according to claim 3 , wherein when the fuel heated by the heater is ethanol, the reference temperature is 80-90° C. 5. A fuel heating method in a vehicle, comprising: sensing, by a start sensor, a starting of the vehicle; measuring, by a resistance sensor, a resistance of a heater provided inside an injector; and converting, by a controller, the resistance of the heater, which is measured when the starting of the vehicle is detected when a failure of communication occurs in a controller area network (CAN) communication device performing the communication with an engine control device, into a temperature of a fuel, and operating the heater to heat the fuel to a reference temperature when the converted temperature is lower than or equal to a threshold. 6. The fuel heating method according to claim 5 , wherein the heater is configured to be operated unless a number of operating the heater when the failure occurs in the CAN communication device exceeds a predetermined value. 7. The fuel heating method according to claim 5 , wherein the fuel heated by the heater is one of ethanol, a fuel mixture of ethanol and gasoline, and gasoline. 8. The fuel heating method according to claim 7 , wherein when the fuel heated by the heater is ethanol, the reference temperature is 80-90° C.
