INNengine – 1 stroke internal combustion engine
- gardenfelder 3y agoAppears that you can preorder a 125cc(??) engine for 100 Eurs. https://innengine.com/shop/ https://innengine.com/shop/
- ksaj 3y agoNot anymore. But the first 200 people that paid 100Euro got to reserve theirs first, even though final pricing has not yet been released. The REX-B is 8,250 Euro and sold out. They are both 23hp, but the Rex-B seems to be a much simpler model. It wouldn't surprise me if the price should be similar, or maybe a bit higher due to inflation, etc. The estimated delivery is December 2023, so I'd hazard to guess the price should be posted soon(ish). The more powerful 120hp version of this is 500cc, but I didn't see anything on the site about it specifically. Honestly, 8,250 Euro seems pretty steep for 23 hp. It's very cool though, and could make a big change in how engines get made in the future, so we'll see how it goes.
- zote 3y agoGreat video about the "one stroke" engine from driving4answers https://youtu.be/9I0_3qFmPUM https://youtu.be/9I0_3qFmPUM
- ksaj 3y agoInterestingly the site only shows 125cc 23hp versions. The video shows a 500cc version with a whole lot more power. I guess the 500cc version will be available to the public later.
- psd1 3y agoI do enjoy d4a. Here's another recent video that has me stoked: https://youtu.be/bwGQlf0y6zE https://youtu.be/bwGQlf0y6zE It's about a non-boxer opposed flat engine, which is an incredibly compact design. That makes it very flexible to package for range extension for hybrids. I'm interested because I want to one day build an electric rail (light sports car), and I want to minimise battery weight. 80 horse of generation could get you 400 peak at the wheels, which would be quite a ride if you can keep under 700Kg...
