Embodiment Construction
[0032] Such as figure 1 As shown, a super-knock abnormal combustion control method for a supercharged gasoline engine is to protect the engine after the super-knock abnormal combustion of the supercharged gasoline engine while ensuring the working stability of the engine, so as to avoid the whole vehicle Driving is not smooth, the specific steps include:
[0033] Step 1, first collect knock signals (vibration signals) through a knock sensor, and perform integral processing on the knock signals by a sensor signal processing module.
[0034] Step 2: The engine controller ECU detects the integrally processed knock signal online in real time, analyzes it and judges the number of consecutive occurrences of super knock abnormal combustion and the position of the cylinder.
[0035] Step 3. If no super knock abnormal combustion is detected, the engine controller ECU will operate according to the original working conditions and parameter settings. If a super knock abnormal combustion ...
