METHOD TO OPERATE AN INTERNAL COMBUSTION ENGINE - ENGINE MANAGEMENT SYSTEM USING ADAPTIVE IGNITION AND FUEL QUANTITY OPTIMIZATION WITH MINIMAL SENSOR REQUIREMENTS FOR STANDARD AND BIO-FUELS

摘要

The present invention relates to a method to operate an internal combustion engine, characterised in 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.
