Abstract
A controller for injectors is provided. A torque difference is a difference between an individual cylinder torque and an all-cylinder mean torque. Correction information indicates a correspondence relationship between the torque difference and an injection correction value. In the correction information, the injection correction value for a case in which the individual cylinder torque is greater than the all-cylinder mean torque indicates a decrease correction. The injection correction value for a case in which the individual cylinder torque is less than the all-cylinder mean torque indicates an increase correction. When the absolute value of the torque difference during the increase correction is equal to the absolute value of the torque difference during the decrease correction, a correction amount of the increase correction is greater than a correction amount of the decrease correction.
