Diesel chainsaw.?

[Huskybill]

Does anyone make a diesel chainsaw yet?

I’m thinking a 10,000 watt generator / welder combo, diesel tractor, two 275 gallon oil tanks. Part of my survival plan?

Ive seen diesel dirt bikes from the army, I would not be surprised in the least an army issued diesel chainsaw. However I highly doubt there is anything that we could purchase unless it’s milsurp if that were the case.

Only the older ones, that seem rare to find, would be neat, along with the diesel motorbike too.

oh, you could take away all your cares and woes with the "Zomax diesel saw - 2hp-2 stroke best workmate generator starter switch japan"

Accurately built by "Happy" workers... virus optional.

Diesel tractor, PTO generator, battery tools, hydraulic chainsaw (tractor hydraulics) Already have a welder?

It has a carburetor and cdi.

1950-53 Comet B, 49 CC, diesel.

RC cars use a type of diesel, I don’t see why It couldn’t be applied to chainsaws...
There is slightly less potential energy in diesel but it is denser which I think makes it slightly more powerful as fuel source

 

[rarefish383]

Comet made 2 models, the B and S. Might be others.

1950-54 Johnsered, 50CC, diesel. Johnsered P Diesel.

Bamse was another. Acres site has an article on them, I just skimmed it. The Bamse was not a diesel, just an interesting saw that was added to the article. The first diesel saws had sealed handle bars that were used to store propane. There was a small propane torch that heated a glow plug to get the saw started. Later saws had a box with 2 "D" cell batteries to heat the glow plug.

That looks like it would be a pleasure to use! Wonder why it never caught on??

Diesel has more potential energy than gas. But it's not really suitable for two stroke (burns to slow) and 4 stroke is to heavy a design.
I hydrolic chainsaw, powered by a diesel tractor on the other hand, works great.

... requires a gas mask for the smoke and radar for lack of visibility

 

[anlrolfe]

Wonder which would be more punishing; a cold start or hot start.
I noticed the can of ether... cold start.
Would a hot start yank your arm out of socket? Happy happy joy joy...

Diesel generator-set and electric saw = diesel saw

I love the smell of diesel in the morning!

Good point, probably why diesel is always turbocharged on the older 2 stroke trucks, such as the screaming jimmy

2 stroke diesels have to either have a blower (supercharger) or turbo. They need the added pressure to push exhaust gases out on the bottom of the down stroke while forcing new clean air in before the intake valves are covered by the piston to start the compression stroke. 2 stroke diesels are really interesting (Detroits). They are probably the most effective means to turn fuel into noise and smoke.

just running some numbers. 14:1 compression ratio (low end for a diesel) would be about 190 psi on the gauge. 18:1 would be closer to 250 psi.
