I encountered such a problem when testing the engine on the bench during the test, the speed of more than 7000 RPM will appear fire phenomenon (before 7000 RPM can run normally). I tried to check the fuel injection, ignition and synchronization signals, and did not find errors, there is that expert can help answer?
Hi,
We need data to help you.
Please post the project file and a log with the misfire recorded.
Tell us the timestamp where the misfire occurred on the log.

I am really sorry, because I am a new user, and can not upload any attachments, the speed of the fire is roughly more than 7200 RPM, which shows that the air-fuel ratio will become very thin. This failure occurs when I increase the speed above 7200 RPM on the engine bench, and I reduce the speed to 7000 RPM and it can operate normally again.

I have just opened the permission to upload. The above are the project files and test data, which appear above 7200 rotations. Looking forward to your reply.
