Method of operating an internal combustion engine

摘要

In a method for operating an internal combustion engine including a control device and having a cylinder including a combustion chamber formed in the cylinder between a cylinder head and a piston and in which a first combustion chamber pressure (p₁) is measured before the start of the combustion, a second combustion chamber pressure (p₂) is measured after the end of the combustion and a third combustion chamber pressure (p₃) is measured during the combustion, and a combustion center position of the respective combustion process is determined therefrom by the control device and the engine operating conditions are adjusted so as to bring the combustion center position to an optimum position for minimizing fuel consumption and exhaust emission.
