Method of operating an internal combustion engine

Abstract

Abstract The injection of the main fuel quantity is not started before the completion of at least three tenths of the total compression stroke. The commencement of injection of the main fuel quantity is dependent upon engine load and is retarded with reducing load so that a mixture forming zone is formed with a stoichiometric fuel/air ratio. The injection of the ignition fuel quantity is not started until at least seven ninths of the total compression stroke has been completed. The spacing between the end of the main fuel quantity injection (6) and the commencement of the ignition fuel quantity (7) injection is less than one tenth of the complete compression stroke. The ignition of the fuel/air mixture occurs during or shortly after the injection of the ignition fuel quantity.
