Title: Fuel composition recognition and adaptation system

Abstract

A method of operating an internal combustion engine. The method including monitoring a pressure in a combustion chamber of the engine during a compression stroke, determining whether a fuel composition has changed from a first composition to a second composition based at least in part on the monitored pressure, and triggering a fuel composition adaptation in response to a determination that the fuel composition has changed.
