Audi 13 year 2.0 t CND engine cylinder intake and exhaust pressure pulsation crankshaft camshaft crankcase

This is a normal car, but the crankshaft waveform is not white


Thank you very much the administrator for converting the waveform format. Thank you

Hi,
Have you seen the video how to properly record the signals?

I recommend you to download Pico settings needed to record properly the cylinder pressure waveform: Please record your in-cylinder pressure waveform again according this test procedure:

Sorry Administrator Maybe I didn't understand how to test the correct cylinder pressure waveform

Hello administrator, how long can you switch? Is it a jet lag?


能麻烦您转换这个波形吗 只要能打开气门正时动画就行 非常感谢

Can you trouble converting this waveform as long as you can open the valve timing animation Thank you very much

Hello,
You did not use the Pico settings file I sent you.

Please download Pico settings needed to record properly the cylinder pressure waveform: Use file Px.pssettings for the measurements.

Test procedure:
Start the engine and allow it to idle.
After 3…5 seconds slowly raise the engine speed to 3000…5000 RPM with minimum opening of the throttle and then close the throttle.
After the idle speed has stabilized, quickly snap the throttle wide open.
Then immediately close the throttle.
Alternatively, instead of closing the throttle, you can turn off the ignition while keeping the throttle open until the engine comes to a complete stop.
If keeping the throttle open while shutting off the ignition, additional information will be recorded for the script tabs "Inlet" and "Exhaust".
Turn off the waveform recording

The waveform should not exceed 50 seconds.
