Abstract
In a method for avoiding a runaway condition of an internal combustion engine that includes a cylinder, an operational characteristic of the engine, presumed to be caused by an unrequested introduction of hydrocarbon into the cylinder, is detected and the engine is derated in dependence of the detection, and, while the engine is derated, a test procedure is performed to detect an unrequested introduction of hydrocarbon into the cylinder.
