Abstract:
A method for operating an internal combustion engine having a combustion chamber including an engine of a motor vehicle wherein fuel is supplied to the engine and a combustion chamber pressure (pBr) develops in the combustion chamber of the engine during operation thereof, the method comprising the steps of:measuring a mean fuel pressure (pm) acting on said fuel supplied to said engine utilizing a sensor assigned to a fuel store; controlling the fuel pressure acting on said fuel to said mean fuel pressure (pm); injecting fuel into said combustion chamber in a stratified mode of operation during a compression phase; and, determining an injection duration (ti) in said stratified mode of operation in dependence upon a pressure difference (deltap) between said mean fuel pressure (pm) and said combustion chamber pressure (pBr).
