I've looked but can't find the thread with the link that was on here a few months ago to an impressive video animation about how an engine is put together and then how it works, can anyone help?

Thanks very much

Deutz engine screensaver maybe? It gives general idea about how 4-stroke otto engine works.

That's the one! Brilliant, thanks very much

Explaining to my lovely GF about why she needed a TDC sensor replaced on her Clio and what TDC is, much easier in animation than words how an engine works

Link here for anyone interested:
