Very easy. DCR is a comparison of volumes. It does not matter whether the engine is motored, firing,CamKing wrote: ↑Sat Sep 11, 2021 12:10 pmExactly.hoffman900 wrote: ↑Sat Sep 11, 2021 11:58 am Did you ever ask him how he defined DCR? It's probably not what most think.
There's a lot of good information you can compile, looking at pressure waves in a running engine.
None of it has any relation to the output you receive from a "DCR" calculator.
How can you input static parameters, and get a Dynamic result ?
or simply measured. Volumes are volumes, period. The volume ratios do not change.
If you believe DCR has limited value, then you must agree that SCR has negative value.
Which DCR calculator do you use? Why?
