Someone please correct me if I'm wrong but I think I've heard the term "suck squeeze bang blow" way before Feb 23, 2021 and also before 2015 (creation of that Youtube channel) so I find that claim hard to believe.
Weird. I've been talking to people about cars for decades and I'd never heard it before them. Is it just something that people don't say anymore?

I guess for whatever reason it's just not used as much, or at least not enough that I've heard it before.
edit: and googling some more, there are instances of in being used it 1950s. And the likely first author of the saying might well be the inventor of the 4 stroke engine himself, Nicolaus Otto, who used a similar saying to describe it: Saugen, Drücken, Knall, Schlag.
> Actually, I wouldn't be surprised if the great Nikolaus August Otto, inventor of the four-cycle engine had a similar saying to explain his engine: Saugen, Drücken, Knall, Schlag...
So I think this is apocryphal.
I do see though that the breakdown of the Otto cycle on most sites including German ones (https://de.wikipedia.org/wiki/Ottomotor) is usually made in a way that just sorts of lends itself to being transformed that way.
Well, thanks for making me go through his writings, this was fun!
