I wanted to know so badly: I’m learning about fuel injection now. I guess I know more about my weed-wacker now, too (We only use carburetors for small engines, now).
It’s kind of fun that the first automotive fuel injectors were just an electronic version of a carburetor: it would just squirt some fuel in by the throttle body instead of the more modern multiport injection further up the manifold or high-pressure piezo injectors directly into the cylinder.

They’re super neat! They shoot compressed air into little drops of gas to make the perfect fuel/air mixture to make a tiny explosion!
Here’s a video describing the whole process and with lots of slow motion shots of the event happening! https://m.youtube.com/watch?v=toVfvRhWbj8

I feel like the air is kinda the opposite of compressed, but I like your comment anyway!
Came here to pont the SmarterEveryDay video; you beat me to it :-)
If it’s making explosions your engine has too much compression.
