Control device and method for internal combustion engine

Abstract

In a control device and method for an internal combustion engine that supplies to a combustion chamber a first fuel having certain ignitability and a second fuel having lower ignitability than the first fuel, an operating state detector detects an operating state of the internal combustion engine, and a controller controls supply amounts of the first fuel and the second fuel to be supplied to the combustion chamber based on an operating state of the internal combustion engine detected by the operating state detector. The controller decreases the supply amount of the second fuel to be supplied to the combustion chamber when the operating state detector detects a transient operating state of the internal combustion engine.
