Method and device for internal combustion engine running

The invention relates to a method and a device for internal combustion engine running. An internal combustion engine is provided with a spraying device for spraying cooling fluid into a combustion chamber (101) of the internal combustion engine. According to the method and the device for internal combustion engine running, the detonation danger is determined under the current combustion situationin the combustion chamber (101), and when the detonation danger is higher than the threshold value, spraying of cooling fluid is conducted for current combustion in the combustion chamber (101). 本发明涉及用于运行内燃机的方法和装置，该内燃机具有向内燃机的燃烧室(101)中喷射冷却流体的喷射装置，本发明提出，在燃烧室(101)中的当前燃烧情况下确定爆震危险，并且，当爆震危险高于阈值时向燃烧室(101)中向当前燃烧中进行冷却流体喷射。
