Abstract
A method for recognizing irregular combustion in an internal combustion engine includes supplying fuel directly to a combustion chamber of a cylinder of the internal combustion engine using an injector. The injector is connected to a fuel supply line that includes a pressure sensor configured to measure pressure in the fuel supply line. The pressure in the fuel supply line is measured during the supply of fuel into the combustion chamber. It is then ascertaining whether irregular combustion is occurring based on the measured pressure in the fuel supply line.
