FUEL INJECTION METHOD OF FLEXIBLE FEUL VEHICLE AND APPARATUS PERFORMING THE SAME

摘要

According to an embodiment of the present invention, a method to detect different types of fuels executed in an apparatus to detect the different types of fuel positioned in a vehicle. The method comprises the steps of: attempting an ignition state of the vehicle from a turned off state to a turned on state; determining whether concentration of a specific fuel escapes from a preset critical concentration range based on a premeasured component ratio of the different types of fuels when the ignition state of the vehicle is failed to be switched; and controlling the component ratio of the different types of fuels to be changed to one component ratio of the different types of fuels among a plurality of component ratio of the different types of fuels in accordance with a determination result. Therefore, the present invention changes each concentration of fuel to be in correspondence to the component ratio of the different types of fuels although different types of fuels are injected into the vehicle in order to improve an ability to start the vehicle, and prevent a no start-up situation.
