Abstract

A method to operate an internal combustion engine, comprising the steps of direct or indirect measurement in a cylinder and/or in a working cycle of the time or point or area/band where the combustion process of an internal combustion engine completes the ignition phase or nears the end of the ignition phase and begins or transits into the combustion phase, or which marks the beginning of the combustion phase, or otherwise marks that the combustion process has commenced.
