Re: In cylinder pressure waveform "blip"

Hi Steve I noticed that the psdata file that you shared in your second post, does not look like the same capture as the one in your first post. The injector current events are different. Or have I mistook something? (quite likely) Nope, you are quite right Dave. The first one was a mistake on my pa...

Re: In cylinder pressure waveform "blip"

Hello, You can record in the intake/crankcase/exhaust pressure waveform at the same time with cylinder pressure? Maybe there is the answer for your question. :roll: Your engine have oil consumption(you can see this using an endoscope)?Only a liquid(oil in this case) pumpimg in cylinder will give to...

Re: In cylinder pressure waveform "blip"

Hello and thank you for the posts, images and waveform as I know they take valuable time to complete. No problem. I am intrigued by the event taking place in the cylinder and have some questions (sorry) if you have time to respond? I'm intrigued also, I will make time as developing skills and knowl...

Re: In cylinder pressure waveform "blip"

Hi Again Steve, Would it be a big deal to put it all back together, exhaust every Non Intrusive testing opportunity available to you. then, hopefully, when you do need to remove a component it will be with good reason Wouldn't be a big deal as injectors back in already. I was happy I'd done all the...

Re: In cylinder pressure waveform "blip"

Hi Steve I've been a member for many years but had completely forgotten about the Pico forum, In that case are you aware of the online waveform library ? (Not the one within the software) The Online version that can only be accessed with the Pico Scope connected to your Laptop / PC. Here is a link:...

Re: In cylinder pressure waveform "blip"

The injector is not in the cylinder. The only way I could check this was using a dummy injector, the injector is lay across the cylinder head with a current clamp connected. All fuel pipes are blanked at the rail to maintain a fuel pressure signal. That will isolate the injection event variable. :w...

In cylinder pressure waveform "blip"

Morning guys. Ive been a member for many years but had completely forgotten about the Pico forum, I just stumbled across it while looking at their website. So, I thought I'd have a look. Would any of you guys who are experienced with in cylinder pressure analysis have any ideas ref the odd dip and b...
