Method and arrangement for operating an internal combustion engine

A method for operating an internal combustion engine including an engine having direct injection or intake manifold injection, the engine having a control apparatus, the control apparatus having software providing a plurality of functions, the method comprising the steps of:

• setting said functions to be executable in dependence upon operating conditions of said engine;
• operating said engine in at least two operating modes thereof;
• setting said functions to be executable in dependence upon operating-mode dependent and operating-mode independent conditions of said engine;
• and,
• wherein executable functions, which are enabled for activation, are only then activated when their operating-mode dependent conditions are satisfied and that the executability of these functions is withdrawn when the operating-mode dependent conditions are not satisfied.

A control apparatus for operating an internal combustion engine having direct injection or intake manifold injection and the control apparatus having a memory including a read-only-memory (ROM) and a computer apparatus including a microprocessor, the control apparatus comprising a program stored on the memory which is suitable for execution on said computing apparatus and for carrying out a method for operating an internal combustion engine having direct injection or intake manifold injection, the control apparatus having software providing a plurality of functions and the method including the steps of:

• setting said functions to executable in dependence upon operating conditions of said engine;
• operating said engine in at least two operating modes thereof;
• setting said functions to be executable in dependence upon operating-mode dependent and operating-mode independent conditions of said engine;
• and,
• setting said functions to be executable in dependence upon the operating-mode independent conditions of said engine when predetermined operating conditions of said engine occur.
