An introduction to in cylinder pressure analysis using the Ditex PDS500G pressure transducer. In cylinder pressure testing is a great way to 'see' exactly what is happening inside the engine. We can diagnose valve timing problems, exhaust blockages, compression loss and much more! Here we look at the basics of in cylinder waveform analysis using the PicoScope 2204A.
The Ditex PDS500X is the full kit available with various adapters, and includes the PDS500G pressure transducer. Kit is available from Elite Diagnostics: elite-diagnostic-solutions.co...
Ditex sent me the kit free of charge in return for a fair review of the product.

@@MechanicMindset I’m still learning this technique but the most common issues I see with the GM vehicles are valve or lack of valve opening due to DOD lifers unlatching . Tbh though ( IMO ) the most useful information i would use it for would be verifying valve timing events. Most of the modern vehicles have cam/crank correlation variance scan tool data and its pretty reliable but its always nice to back up that data. An in cylinder test is a great way to do that. I personally don’t use it very often ( don't get too many situations that require it on a daily ) but when i do its a great tool to have. Kinda long winded answer right LOL.

Pointing put that the PicOScope likely isn't causing the steps in response. The steps appear to be the update rate from the pressure senor itself. The little spikes on the plateaus are the at the scope sample rate, which is a bit low @ 8k/sec. Could raise that to 100k or even 1M and still have plenty of buffer.
@MechanicMindset 2 жыл бұрын
I’ll give it a go, but pretty sure this is a vertical resolution issue. The 2204a is 8bit so only has 256 vertical ‘steps’ to recreate the scope waveform image. Compare this to a 12bit scope which has 4096 vertical steps and it will create a much smoother line 👍
@paulmills7366 3 жыл бұрын
Does the waveform pattern change much when comparing to an Atkinson or Bodack cycle engine?
@MechanicMindset 3 жыл бұрын
Assuming we can get the engine to run in this mode with a misfire and injector fault at idle, I suppose we would see some difference in the valve activity. As I understand, this mode is created using VVT and such so not sure when it is activated (assuming it runs normal Otto at idle?). Great question! 👍
@rudimaier3679 3 жыл бұрын
Hi Darren! Just a question. Justin Miller have a lot of useful videos like you with the 2204a on his channel. He is recommending to always max out the sample rate to 2MS i think. What do you think?
@MechanicMindset 3 жыл бұрын
Hi, Justin has some great content! In my opinion it’s no necessary to max out the sample rate; you can end up picking up unwanted ‘noise’. If you use a higher time scale (I.e. 200ms +) and you want to see detail after, then yes. I don’t often increase the sample rate. In fact, I have reduced for some tests to get a cleaner line (4425 has low pass filter which has a similar effect)

Hey Daniel, I haven’t made one of these yet. I made a pulse sensor (for very low pressures). You can make these, but for a good waveform I believe you need a really good transducer. If your serious about using it for diag, I’d buy one. There are some videos about of people making these too though 👍. You can get this sensor without the kit and just use the adapters from a standard compression kit; it’s more affordable that way. But this kit is great for the price.
