Abstract
A control device compression-ignition type engine that compression-ignites an air-fuel mixture in cylinders by introducing ozone into the cylinders at a predetermined operating range is provided. The control device detects a first ignition timing of an air-fuel mixture when introducing an intake of a first ozone concentration into the cylinders, detects a second ignition timing of the air-fuel mixture when introducing an intake of a second ozone concentration that differs from the first ozone concentration, and determines the fuel ignition ability based on a difference between the detected first ignition timing and the detected second ignition timing.
