| description | A method for knock control during KC emergency operation with which, given low application expenditure, a torque gain can be attained, while the application reliability increases. The method for knock control of multi-cylinder internal combustion engines having 2n cylinders, a cylinder counter, at least one knock sensor and an evaluation unit for evaluating the knock-sensor signal with the aid of an individual knock-recognition characteristic for each cylinder, is characterized in that during KC emergency operation, cylinder pairs are formed from the cylinders operating offset in each case by 360°, and the minimal value of the two knock-recognition characteristics of the cylinder pair is assumed in each case as the knock-recognition threshold for the cylinders of the cylinder pair affected by the malfunction of the phase recognition. |
