摘要： A method for controlling fuel switching of a fuel switching system in a vehicle via a controller configured to receive one or more measured signals in order to issue a fuel shortage warning or in order to control fuel switching is disclosed. The system includes an LPG rail pressure sensor for measuring a pressure in an LPG rail, and a bombe pressure sensor for measuring a pressure in the bombe. The method includes a first LPG rail pressure determining step of determining whether the pressure in the LPG rail is lower than a second reference value or not and a first bombe pressure determining step of determining whether the pressure in the bombe is lower than a third reference value or not. If at least one of the first pressure determining steps is positive, the method further includes switching the fuel to gasoline.

摘要： A method for improving a change of fuel in a bi-fuel vehicle includes: a step of measuring an LPG level in an LPG fuel tank; a pressure reference driving step of continuing the driving of the vehicle using the LPG fuel; a pressure change rate reference driving step of continuing the driving of the vehicle using the LPG fuel when it is determined that the vehicle may be driven by the LPG fuel by comparing an LPG rail pressure change quantity and a pressure change quantity in the LPG fuel tank with a set reference value; and a fuel expanding step of continuing the driving of the vehicle using the LPG fuel when it is determined that the vehicle may be driven by the LPG fuel by comparing an injection quantity of LPG fuel and an accumulated value of mileage with a set reference value.

摘要： 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.
