a chap I know in the agricultural contracting line of work has just bought an old american built machine powered by a v6 detroit diesel.
Had a look at it the other day and was amazed to discover the blindingly obvious to anyone familiar with them, they are two stroke, and rev like you
wouldn't believe!!
Why are two stroke diesels out of fashion in mobile stuff???
Call me daft but for me its worth it just for the noise, it sounded AWESOME!!!
here's a clip I found on youtube of a wagon with the same engine.
detroit diesel noise!
bet it doesnt do many mpg
but does sound awsome
sounds mint but all that black smokes proberbly the reason they dont make em now
The old Commer TS3 ? used a two stroke diesel IIRC it had two pistons in the same bore?
The Commer TS3 two stroke diesel of 60/70's vintage was recently tested along with current trucks and was found to meet many of the current
emissions standards and was very nearly as economic! Not bad for a 1950's design.
In case you are wondering it has 3 cylinders and six pistons (2 in each cylinder), it is piston ported (no valves) and is supercharged!
A similar engine was used in some German Junkers bombers during WW2.
My favourite engine of all time is a 2-stroke diesel, the Napier Deltic , its a bit heavy and
complex for a seven though....

We had a pair of them in HMS Bickington, exhausts used to catch fire every morning due to piston slap
^^^^
Thats what they are
there was a pair in a scrap yard I was at a few weeks back. They are huge
They looked turbocharged ?
I was going to look them up but forgot all about them.

ps the smoke is tweaked pump, not std!!!!
Wonder how long the 0.5 capacity rule for diesels would last if people started using them for hillclimbing
Worked a Terex TS24 motorscraper when I was younger, which ran two detroit V8 motors front and rear, mental noise and power
Can't remember them being overly smokey either, even under load

Two Stroke Diesel
more than 50% efficiency, so almost theoretically perfect and 100,000 BHP at 102 RPM.
no the Napier Deltic
Found this on you tube, check it out

Sounds like my old aircooled 350 Yamaha. Smokes about the same too.
Old Foden lorries used a two stroke diesel and the one that used to pick up from the steel firm I worked for was really loud, you could hear it coming down the bypass 5 minutes before it pulled into the yard.
Small compact 200hp all alloy V6 two stroke.
Suzuki DT200 are 2.7l
Sound of a Yam V6 outboard.
