Abstract
There is disclosed a fuel property detector for detecting a property of fuel injected by a fuel injector into a cylinder of an internal combustion engine. The fuel property detector includes an injection commander, a change detector, and a fuel property determiner. The injection commander commands the fuel injector to perform a fuel injection for fuel property detection into the cylinder of the engine. The change detector detects a change in the rotational speed of the engine which is caused by the fuel injection for fuel property detection. The fuel property determiner determines the property of the fuel based on the change in the rotational speed of the engine detected by the change detector.
