Abstract

A control system for an internal combustion engine wherein a load applied to the engine from at least one auxiliary component and/or an air conditioner, which are both driven by the engine, is reduced when the engine is operating in a predetermined low-load operating state. A property of the fuel in use is estimated based on a combustion state of the injected fuel after the reduction of the load applied to the engine.
