CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE (AS AMENDED) |
| 摘要 |
A control apparatus for an internal combustion engine according to the present invention includes a spark plug (30) for igniting an air-fuel mixture in a cylinder, and is configured to be capable of measuring a discharge voltage of the spark plug (30). The control apparatus calculates a turbulence intensity index value that indicates the turbulence intensity of in-cylinder gas based on a predetermined frequency component extracted from a discharge voltage during at least a part of a discharge duration leading up to ignition and, in accordance with the turbulence intensity index value, adjusts the ignition energy that is supplied to the spark plug (30) during a combustion duration in a cycle in which the turbulence intensity index value is calculated. |
