Abstract
A method for correcting a deviation of static flow rates of GDI injectors is provided. The method includes calculating a target pressure drop amount for each cylinder and a relative pressure drop amount for each cylinder from a detected pressure drop amount. An injection correction factor for each cylinder is primarily adjusted by comparing the relative pressure drop amount for each cylinder, with an average of relative pressure drop amounts of all cylinders. The injection correction factor is then secondarily adjusted by comparing an average of injection correction factors of all cylinders with 1.
