Abstract

In a method of operating an internal combustion engine with direct injection of fuel into an engine combustion chamber during a compression stroke of a respective piston wherein first a main fuel volume is injected and subsequently an ignition fuel volume is injected into the combustion chamber, the injection of the main fuel volume is initiated only after about 3/10 of the compression stroke of the piston has been completed.
