commer diesel ts3

[R.O.R-2.0]

The rings pull oil right out the exhaust port.

with an engine like a jimmy, with exhaust valves, how does that happen?

Couple of vids I found.
Another one running.

And a good one showing the weird internals they use, and supercharger. Note the engine is a display model and the noise is another old engine driving it.

I missed out on getting one of these out of a mates shed during a clearout a while back. I just had no room at the time to store it. :-(

how come you can only buy exhaust valves online for a jimmy?

first part of the article clearly states that they have exhaust valves..

Yes, air comes in ports at bottom of cyl. Exhaust is pushed out valves in head. IIRC, there was a Jimmy made with no valves, sort of like a 2 stroke gasser, but apparently it wasn't that efficient due to poor scavenging.

air comes in the middle of the cyl , i usto take of the air box plates and get a screw driver to check the rings, give them a we push in and see them spring back , and with the piston at BDC you could look up and inspect the bore , the only time i would see blue smoke coming from the exhaust was when the bores were glased and the oil control was gumed , eather from that i think thay are good engines 4 71 ,6 71  v8s and the v8 92s  ,worked on some v12s  and a few v16 with twin turbo , bolted to a HT 400 halliburton pump

So I had a little new year party and I showed this thread to a friend of mine that is a medium/heavy duty truck mechanic and he said he's never seen anything like this engine here in the states, so I'm thinking this kind of technology never made it over here, which is a damn shame.

Totally bonkers, saw one at an autojumble last year, but it was about 3' square, and about 2' high, unlikely to fit many engine bays. They worked well, allegedly.

Google "napier deltic"  if you really want diesel madness.

Ah, the Napier & Sons Deltic engine; triangular triple 2-stroke valveless opposed-piston diesel engine.  3 crankshafts.  3 cylinders, 6 pistons, and that is just one bank.


Now imagine that with 3 to 6 banks.  That's 18-36 pistons!  Couple all that with a biiiiig nose mounted supercharger, and you get an engine that can power anything from locomotives to navy fast attack vessels.  I actually used to be big into train stuff when I was little, so I actually knew about this engine before I was a diesel geek.  THEY SOUND SOOO COOL!!  I just love any really wacky engine that exists, from hit-and-miss, to opposed-piston plants like that commer, to . . . well this
