These One-Cylinder Diesel Engines Run at Amazingly Low RPM and Look Awesome

I love a big diesel engine as much as anybody, but they aren’t always practical. While I’d love to own a V16 two-stroke Detroit or whatever else, there’s no way I could actually use one—I just don’t have the need. Surely, though, I could find a use for these Yanmar single-cylinder diesels that are water-cooled, hand-cranked, and happy to run at virtually zero rpm.

It helps that you don’t need a full garage to store one, as these can live on a tabletop or a pushcart if needed. And they’re nothing new, either, which is part of what blows me away. They’re still being made, albeit for other markets as the United States (and specifically California) are phasing out small engines due to emissions.

Still, I think these are worth talking about, and this recent clip of one that went viral on Instagram and TikTok proves plenty of folks are interested in them:
