Knock control system, combustion engine and method of operating the same
A knock control system (100) for a combustion engine (10) is disclosed. The knock control system (100) may allow the combustion engine (10) to operate closer to an actual knock limit by providing two knock thresholds (Th1, Th2). The first knock threshold (Th1) separates a safe operating region from...

| description | A knock control system (100) for a combustion engine (10) is disclosed. The knock control system (100) may allow the combustion engine (10) to operate closer to an actual knock limit by providing two knock thresholds (Th1, Th2). The first knock threshold (Th1) separates a safe operating region from a region in which some knocking may occur. The second threshold (Th2) is closer to the actual knock limit of the combustion engine (10). The combustion engine (10) is allowed to operate in the region between the first knock threshold (Th1) and the second knock threshold (Th2) as long as knocking above the first knock threshold Th1 only occurs for a certain number of times. When a predetermined maximum allowable number of times are exceeded or knocking above the second knock threshold (Th2) occurs, the combustion engine (10) is caused to operate in an alternative operating mode with a reduced amount of knocking. |
