No, but I did see a Stihl saw on YouTube that was powered by a small jet engine. I enjoyed that and I would also enjoy a diesel saw!

Jonsereds made one.
Beat me to it...they did make diesel saws.
I have the Jonsreds one,it needs a recoil.

Maybe the should remake them seeing how California won’t sell any “gasoline” powered outdoor equipment.

I'm waiting for the wood-fired steam engine version.

One of the leading small trainer planes has one with a diesel engine. With airplanes you *really* care about weight, so the power/weight ratio is comparable to gasoline engines. And most aircraft gas engines are air cooled.
Mind you an aircraft is in a different services enviornment. Aircraft engines typically run at 70-85% of max power for hours at a time. Power demand tends to not fluctuate much. A Cessna's prop spins at 2000-2500 rpm. Plus I have no idea if the tech miniturizes well. A cessna 150 has a nominal 150 hp engine in it.
Could be interesting. Aluminum block with steel liner? Alloy crank?

Not really so heavy, but is does have a lot of compression. No recoil starter, just a starter pulley and a rope. The tubular handle is a propane tank to fire a burner to preheat the head.

i had a diesel aero engine like this, tapered bore, ringless piston, and sliding liner to increase the compression after starting it, loved the smell of the castor oil 
No they were not heavy.at all
I have one of the Jonsered diesel diesel saws. As Mark said they were designed.to hold propane in the handle to heat the cylinder. They also made a model that used a battery.to power a glow plug. That was much more rare.
Good idea!
I did get to hold that sachs dolmar wankel style chainsaw before from a guy who collects and sells vintage saws. Wow was it cool! Never seen the diesel saw but it looks light years ahead of its time. Crazy how technical/mechanical things were in the past. Things that were done then seem like it can no longer be done today.
It's not that it can't be done but weather the scale of production /sales wood be worth while after the RD.
Who wood have thought that in say 1960 or even 1980 that we wood be running 8 axis cnc machines, or cut parts out with lasers and waterjets that required no finish machining. or scan a part in 3d and reproduce it on a printer.

Bill would you have any parts for the Jred diesel? I have one that is missing the recoil.
Thanks
