It's a simple engine diagnostic system based on crankshaft acceleration......

The author just types with a repetitive stutter

[Holden202T]

I think the technical term for that is a head fuck

fffffffffuuuu!!! WALL OF TEXT!

Good luck finding any rhyme or reason in a US patent application, they approve almost any gibberish

It's all relative, the camshaft acceleration would be 1/2 that !
