METHOD FOR DIAGNOSING GAS INJECTOR AT BI-FUEL VEHICLE

摘要

The present invention relates to a method for diagnosing a gas injector in a bi-fuel vehicle. The method for diagnosing a gas injector in a bi-fuel vehicle comprises a sensing step for sensing a current flowing to a gas injector by applying a test voltage to an operation circuit of the gas injector at regular time intervals when using gasoline as a fuel; and a determining step for determining an error of the operation circuit of the gas injector if the size of the current sensed through the sensing step is smaller than the predetermined size. According to the present invention, the method for diagnosing a gas injector in a bi-fuel vehicle can make a user of the bi-fuel vehicle relieve anxiety by diagnosing the gas injector when using gasoline as a fuel rather than at a point of time of converting a fuel to use gas as a fuel.
