Understanding how an internal combustion engine works is pretty straightforward, but there are tons of small details that are often overlooked. This video is here to show you all the details, functions, and features on an engine block that you might not know existed.
, the same YouTube channel responsible for that fantastic stop-motion Miata engine teardown clip we showed you a few months ago, is back with another great engine explainer. This time, it's focused on information rather than cinematic style, but trust us, this is still worth a watch.
The host, using a completely torn-down engine block from a 2001 Miata, talks you through 18 straight minutes of how the piece is formed, what materials are used, and all the intricate details that you might not know about. He explains things like oil channels, coolant paths, pressure sensors, and why the cylinder walls are cut with a cross-hash pattern (it's to keep the oil from sliding down away from the piston ring).
Those are just of the few of the things mentioned, though. Watch for yourself to hear about the rest.
