| 1. A control system for an internal combustion engine, comprising:
fuel property estimating means for injecting fuel into a combustion chamber of said engine and estimating a property of the
injected fuel based on a combustion state of the injected fuel; and

which are both driven by said engine, when said fuel property estimating means performs the estimation of the fuel property
in a predetermined low-load operating state of said engine.
