Method and device for the transient operation of an internal combustion engine, in particular for a motor vehicle

A control element for a control unit of an internal combustion engine, the control element storing a program that can run on a computing unit, the program being suitable for carrying out the steps of:

• using a delivery pump, delivering a fuel to a pressure chamber to build up a pressure acting upon the fuel;
• determining the pressure acting upon the fuel in the pressure chamber within a transient range, the transient range being between a first pressure acting upon the fuel in the pressure chamber and a second pressure acting upon the fuel in the pressure chamber;
• injecting the fuel by at least one injection valve from the pressure chamber directly into a combustion chamber of the internal combustion engine as a function of the determined pressure;
• and
• adjusting a working point of the internal combustion engine upon a transition from the first pressure to the second pressure as a function of the determined pressure.

An internal combustion engine, comprising:

• a delivery pump;
• a pressure chamber receiving a fuel which is placed under a pressure by the delivery pump, the pressure chamber including a pressure sensor measuring an actual pressure acting upon the fuel in the pressure chamber, the internal combustion engine operating within a transient range between at least two working points that switch from a first pressure acting upon the fuel to a second pressure acting, upon the fuel;
• an injection valve;
• a combustion chamber, the fuel being injected directly into the combustion chamber by the injection valve from the pressure chamber;
• a processor arrangement calculating the actual pressure acting upon the fuel within the transient range between a first working point of the at least two working points and a second working point of the at least two working points;
• and
• a control arrangement adjusting a working point of the internal combustion engine as a function of the actual pressure acting upon the fuel.
