Abstract

A method of estimating antiknock properties of a multi-fuel injection internal combustion engine includes: acquiring a first antiknock property-correlated parameter value while only a first fuel having a low octane rating is injected in a first load range; estimating a first antiknock property of the first fuel based on the first antiknock property-correlated parameter value; acquiring a second antiknock property-correlated parameter value while the first fuel and a second fuel which has a high octane rating higher than the low octane rating are injected in a second load range higher than the first load range; and estimating a second antiknock property of the second fuel based on the second antiknock property-correlated parameter value and the first antiknock property of the first fuel.
