Abstract

A control device for controlling an engine including an injector that supplies fuel into a cylinder and an in-cylinder pressure sensor that detects an in-cylinder pressure being a pressure inside the cylinder, is provided. The device includes a processor configured to execute an abnormal combustion determining module to determine whether combustion of a mixture gas inside the cylinder is abnormal based on a detection value of the in-cylinder pressure sensor. The abnormal combustion determining module determines that an abnormal combustion has occurred in which progress of the combustion of the mixture gas is excessively fast, when an in-cylinder pressure intensity that is a spectrum value of a frequency component of an in-cylinder pressure waveform less than a given reference frequency is greater than or equal to a given determination intensity, the in-cylinder pressure waveform being detected by the in-cylinder pressure sensor.
