In the land of the dinosaurs, the behemoth two-stroke Detroit Diesel is king

How about a Napier Deltic diesel engine. Three crankshafts, three roots blowers, three sets of opposed pistons set in a triangle. Saw them on US Navy Swift Boats during the Vietnam conflict. There is a nice animated video of that arrangement on YouTube.

The Detroit’s used individual push rod operated injectors for each cylinder. A fuel gallery ran through the head to supply the injectors.

Fun article and the comments are even better!
Something akin to Sheldon discussing with his train buddy if the dinner train their on an original link-and-pin coupler or the Miller Hook and Platform…

I worked at an airport as a Firefighter on the crash rigs (sorry that’s what they were called) had Detroit Diesels in them. Those engines were so loud and put out so much smoke I can’t smell or hardly hear today! Mike

Not a diesel guy that said a fella in the town i lived back in the early years had a tandem dump with a Detroit in it that truck even at idle sounded menacing to this day i remember that sound and he was quite the master at shifting that rig and would roll out and punch it early every morning wide open thru the gears it was my alarm clock. LOL.R

Amazing bunch of engines, these early Detroits. And the sound, especially with only small amounts of exhaust muffling. There are a few things out there that will make me cut the radio and roll down the window, regardless of the outside temperature. They include an old Ford Louisville with a Detroit Diesel, anything with a big Caterpillar, and anything Maserati. Add to that any of the manual transmission G35/G37 from Infiniti. Wonderful music.
