Re: WPS500x

Thanks Victor, I think I could do with some research material for the WPS500x. Referring back to my example waveform above, which I produced myself using a 3 cylinder twin OHC engine, the exhaust stroke I am paying attention to. The pressure in the exhaust system is atmospheric (static) when the eng...

WPS500x

Hello, I have been collecting some waveforms using the WPS500x. I have limited information regarding the analysis of the waveform results, however having studied the waveforms a little, one thing seems to stand out at me at the moment that does not appear correct! Referring to the capture I have inc...

Re: Transporter 2.0TDI CR Outs Temp sensitive

My casus is about my VW Transporter (2010) 2.0 TDI CR with engine code CAAC. The car was bought 1,5 year ago with 56K and has now 95K km. The problem is that my car seems to be very outside temperature sensitive. The engine always starts very easy but with higher outside temperatures starts to run ...

Re: Using the rotational rulers

Would it be fair to say then that there would be no correlation between the scope linear crankshaft movement in degrees, and the manufacturers circular and spiral valve timing diagrams? No. There is certainly a correlation. It's really only a concern when you are picking the fly shit out of the pep...

Re: Using the rotational rulers

Here is a V8 Ford EDIS CKP. Phase rulers frame 360 degrees and the measurement ruler is at true TDC zero degrees. Look how far off the measurement data is. Hope this helps. Thanks Tom, I see with the rulers what you are pointing out, and what is also interesting on your trace is the peak to peak vo...

Re: Using the rotational rulers

This is a discussion about how to make 2D A3 map of the globe. It will never have the right dimensions. Technician, angular speed of the crankshaft is not constant. An real graph/math should take into account the crank sensor signal frequency. Then you get right the opening closing degrees of valve...

Re: Using the rotational rulers

Speck, I think you are missing the point. Maybe I was not clear enough. Imagine a crank sensor. Each rotation is 360 degrees. Graph the frequency of a high resolution CKP and see what you get. Frequency changes and you can see each individual cylinder firing acceleration in the frequency graph. As ...

Re: Using the rotational rulers

Thanks guys for your valuable feedback, which is very much appreciated. I have completed some engine testing using the WPS500x, and measured the crankshaft, camshaft and fuel injection event. As this is a brand new area of thinking to me I was wondering what the relationship between the WPS500x pres...

Using the rotational rulers

I would like to use the scope and let the scope calculate the number of degrees of crankshaft rotation mathematically without me manually counting the scope wave forms teeth. I have used the rotation rulers and can adjust them from one to four to measure up to 720 degrees, however if possible I'd li...
