So INNengine, is a pioneering company in engine technology, and they have developed two groundbreaking concepts: the e-REX and the REX-B. These engines feature the INNengine patented 1Stroke technology, offering significant advantages over traditional 2-stroke and 4-stroke engines. With improved power, efficiency, compactness, and reduced emissions, the INNengine 1Stroke engines are poised to revolutionize engines in various applications, including range extender systems, aviation, power generators, maritime propulsion, and hydrogen applications.
So how does it work? Well The INNengine’s 1Stroke Technology is based on a unique design that enables four times more power events per revolution compared to a conventional 4-stroke engine and twice more than a 2-stroke engine. By eliminating the crankshaft, valves, camshaft, and cylinder head, the 1Stroke engine achieves remarkable reductions in size and weight, making it highly compact and lightweight. According to them one of their units will be twice as powerful as a traditional 4 stroke engine whilst being 70% lighter and 55% smaller.
The INNengine’s unique 1Stroke engine design combines the efficiency of a 4-stroke engine with the simplicity, compactness, and power of a 2-stroke engine. This innovative engine operates on a system of two identical/reciprocal cam-tracks, which define the engine’s cinematic properties. These cam-tracks project onto a hollow and split main shaft.
The engine utilizes an opposed-piston configuration, where two piston groups work in tandem. The linear stroke of the pistons is transformed into rotational movement by interacting with the cam-tracks. This interaction also controls the opening and closing of exhaust ports before intake ports, enabling efficient uniflow scavenging.
The INNengine’s design allows for a variable compression ratio without requiring complex double crankshaft solutions. Instead, the shifting device, controlled by the engine control unit (ECU), adjusts the axial position of the inner shaft. This offset angularly modifies the cam-track profile, dictating both the distribution and compression ratio as per demand.
Despite having cylinder ports like a 2-stroke engine, the INNengine’s operation is fundamentally different. The combustion chamber of the 1Stroke engine has two combustion events per revolution, which is four times more than a 4-stroke engine and provides double the power of a traditional 2-stroke engine.

Hydrogen is the future, not environmentally toxic lithium batterys.
Dankie! Waardeer jou werk.
Hi Chris, didn't make the live… will try harder next time 😉.
This could be an interesting engine, even though it's a two stroke tbh, but hey, marketing bs…
I do like it, less moving parts and probably can use a range of fuels.
a 1000 cc and 250 HP version of this engine should be enough for any kind of car suv van and transporter.
Very interesting video, good pacing to 🙂
Awe
I still see two strokes…. The pistons move one way, then another. There's a compression and power stroke. That's two strokes. It will need supercharging to get combustion air into the cylinders. VW has settled on 500cc per cylinder engines, which with tuning, can make 100hp per cylinder, using 4 strokes. If converted into 2 stroke, it would be closer to double. But, once you adjust for the energy density difference between hydrogen and gasoline, you'll see why the hydrogen 2 stroke gets 120hp.
Excellent report………as usual.
All I see are CGI and plastic models.
All I hear are buzzwords with no substance.
I call bullshit.
Pity these type of engines have litte to no tourqe at low rpms. The orbital engine they tried 20 years ago with the same basic concept failed
you are good at finding interesting videos
I'll stick with electric, thanks
8 cylinder are back babyyyy🎉🎉🎉
You're spreading misinformation. Know the simple basics between 2 stroke and 4 stroke first. This is not a 1 stroke engine. Their website says 1 stroke is a marketing gimmick
Its not one stroke, it's 2 stroke
It's still a 2stroke engine😂
Analytically it's an alternate firing 2stroke, 2cylender engine with emission problem.
sadly initially only as range extender. this is that actually F1 that really intends to "opposed piston" engine but with 2 stroke instead of 1 stroke. great reports
This engine has all kinds of problems.
That 1 stroke is absolute BS! That is a 2 stroke with some updates from the original like not burning the lubricants. But it does exactly what a Trabant engine does when you look at the combination circle, that is what makes the difference between 2 and 4 strokes! Also this 2 power strokes per circle is just not true except for the 2 cilinders that fire at the same time but that is like just putting 2 normal 2 stroke engines together it's not really a new thing just twice the old. There are real great things about this engine like power from the size and weight. That is what they should be marked not that 1 stroke BS😂
Why would you combust hydrogen when you could use fuel cells to generate energy with it?
Is the chain efficency higher this way?
Or does the fact that you don't need a platinum catalyst, offset the price so much that it outweighs the expected lack of efficency in that way?
really a 2 stroke
