For anyone curious, the Detroit Diesel, aka the Screamin’ Jimmy, is the canonical example of a 2-stroke diesel.
Fun fact: these engines all have a supercharger — which is required to start the engines - but are considered naturally aspirated. GM also made turbo-charged variants (which still had the roots blower for starting) that are properly forced-induction.
A few videos:

These things were kind of prone to running away, with a lots of myth and folklore about catastrophic explosions and death and destruction, so there are a fair number of Youtube videos where people rig these things to run away. This is, without a doubt, on many levels, the best example of the genre: https://youtu.be/bLRF-LRgvJk https://youtu.be/bLRF-LRgvJk
- userbinator 3y agoIn the UK, Foden also made 2-stroke diesels, but they were nowhere near as popular or long-lived as in the US: https://www.youtube.com/watch?v=5pwhm_xoDiY https://www.youtube.com/watch?v=5pwhm_xoDiY What they all have in common is the sound that makes people think it's not a diesel, because the 2-stroke cycle causes them to sound like they're turning twice as fast as a 4-stroke. A 2-stroke at 2000RPM sounds like a 4-stroke at 4000RPM.
