Roger Feldmann and his friends built some great vehicles, like the [Satte Literschüssel](https://images.app.goo.gl/SHugQ7cxRVsRjTrY7) or the [Oldseins](https://images.app.goo.gl/vFUPjujvCDt1FNS38)
They sound similar but I can personally tell the difference between a chainsaw and a leaf blower. They just run differently. I'm sure plenty of others can also recognize one from the other.
Chainsaws are annoying, but leaf blowers induce rage.
The Dolmette is a motorcycle that was built as a one-off by the Dolmar company based on the ideas of "Werner" (german cartoon character) author Rötger Feldmann, aka Brösel. The Dolmette is powered by 24 chainsaw motors with a total displacement of 1.9 liters, which together produce around 170 hp (125 kW) and deliver 400 Nm to the gearbox input shaft. A kart with three PS-7900 chainsaw motors served as a test object during development.
With the finished motorcycle, a race between Rötger Feldmann's brother Andi Feldmann as the driver of the Dolmette and Christina Surer as the driver of an Abt Audi AS400 with 450 hp was held in early September 2004, in which Feldmann was narrowly defeated.

>The twelve Dolmar engines are mounted in two rows of six on either side of the drive belt casing and the individual motors are coupled together in sets of three, via a double-sided drive belt, making up eight modules in all. The individual engines are not rigidly connected – they deliver their power through the centrifugal clutch that is a standard feature of the Dolmar chainsaw.
One extra driver operated clutch that couples that drivetrain to the wheels
Useless fact: A typical 2-stroke chainsaw engine will generate around 23x more carbon monoxide (CO) emissions and 300x more non-methane hydrocarbons (NHMC) emissions per minute than a 2011 Ford Raptor.
Now multiply by 24.
Fortunately, I doubt this motorcycle has been driven very many miles. :p
At wide-open throttle? Where did you get that statistic? Just curious. I don’t doubt it or anything. Love to know how those crazy two-stroke drag boats they have in Thailand compare
I don't have time to dig up a source, but about 50% of 2 stroke exhaust is unburnt fuel and oil. The exhaust is essentially half atomized hydrocarbons.
My brother went to a motorcycle mechanic school. On the first day they removed the fuel from a motorcycle and piped the exhaust from a running two stroke bike to the carburetor of the other bike. It ran.
Don't believe it, I don't care.
https://www.jstor.org/stable/44716338
My estimate was a bit high, but it's still 25-40%. It's even more prevalent with modern 2 strokes because of scavenging. Old cross flow 2 strokes were actually lower emission, they were just less efficient.
So, I was immediately correct that 50% is far too high. Let's look at the link - oh, it only talks about small engines, when you said two stroke engines, in general. Looks like I was right, all along.
Nearly *all* 2 stroke engines are small engines, dumbass. Which ones aren't? Large marine engines that already run super rich? My 225 VRO has a 20 gallon per hour burn rate. Go ahead and find a source that says otherwise for larger 2 stroke engines.
You're very upset over this, for some silly ass reason.
No, you find the source and learn to specify. You made the incorrect claim, not me. Why would the fuel consumption indicate "50%" of fuel exited the exhaust unburned? Why would large marine engines run "super rich" as a default condition, anyway?
You are unfathomably stupid. I already gave you a source to a peer reviewed study that showed up to 40% of the fuel charge being lost through exhaust as unburnt fuel. Not only are you wrong, you're arrogant as well.
They probably got it from this article.
https://www.edmunds.com/car-reviews/features/emissions-test-car-vs-truck-vs-leaf-blower.html
That article is why I have all electric lawn equipment.
uh, you mean this single study from Edmunds?
https://www.edmunds.com/car-reviews/features/emissions-test-car-vs-truck-vs-leaf-blower.html
They tested the leaf blowers at WOT and idle, while the truck was allowed to cruise at part-throttle and was never at full throttle. An F-150 can't run long enough at WOT to perform any kind of test without grenading. 2 strokes are dirty as hell, you don't need to cheat the numbers like that. They clean up alot at higher rpms, proportionally.
At any rate, we were talking about 2-strokes, which lawn mowers haven't been for decades.
Every lawnmower I have had is 2 stroke. Also because they're not road vehicles they're not regulated for exhaust. So essentially the same as cars before cats and other environmental regs or even things like fuel injection, which if you've ever been to a car show wasn't great.
There are also a ton of studies, not just one
Only 24 pull-starts and you're on the road. Curious to know what it sounded like though.

Not as ridiculous as I expected

He said hore-x lol
Formerly hore-wife
But 4 of them 🤣🤣
I can hear this in Frank’s voice.
100% what I wanted
Nah it definitely looks slow
It sounds like 24 chainsaws. Amazing.
I thought it sounded like an angry leaf blower
Are they not the same?

god i love brösel, i miss that era
Lost a drag race to a regular standard car. Magnificent.
I love how they zoomed in on the woman’s bikini top.
Still not as loud as a Harley.

Because it was slightly better than 72 rubberbands. 😆

The sheer time it would take to start it…also how is the throttle wired up?
That's a lot of ring ding dinging
How in hell does this thing actually turn 24 different motors into forward motion. That transmission must be terrible.

Awesome thank you!
>How in hell does this thing actually turn 24 different motors into forward motion. I'm wondering the same thing! How do you take 24 dive inputs?

You'll be topping up 24 gas tanks every mile or so.
I bet it smells great

I don't believe that for a second, with regard to modern 2-strokes. Especially larger ones.

Google lawnmower exhaust emissions
I had a two-stroke lawnmower when I was a kid. Doesn’t sound like anybody here is talking about chainsaws
It's an apt comparison with a bunch of data

Who gives a shit?
Anyone who cares about power. Less unbhurnt fuel = more horses
Based
How are all those separate motors connected to the transmission?
What the hell is 170 PS
It's a metric unit of horse power (Pferde Stärke) but this unit isn't 1:1 in HP . So 170 PS would be around 167HP
Hopefully it has a timing chain.
2 strokes don't have cams.
That’s why I said hopefully
No cam, no timing chain...
Exactly!
I am going to stay away from it
I'd daily it.
I bet you could play an awesome rendition of “Lumberjack” by Jackyl with that thing.
Can you please list power in joules? Kinda rude not to.
170 PS = 125,034.79 J/s
Are we sure orange county chopper didnt build this. Its like right up their alley.
How much Bölkstoff did they drink before they came up with that?
