6.5 meter tall 1 cyl 2 stroke diesel engine - 81 litre

[Busa_Rush]

In this brilliant little museum . . . http://www.motoren-museum.nl/

81 litre 2 sttroke diesel engine. Ticks over at 45 rpm, the exhaust pipe is as wide as a dustbin, needs to be started using compressed air. The owner starts it once a month . . . surprisingly smooth

Specification


Starting involves setting piston at just over tdc using a lever on the flywheel
The con rod can be seen through the perspex window on left


Cylinder Head


Exhaust

Epic! needs a brace of turbos though!

2 stroke seems to be the norm for these massive diesel engines etc.

Isnt this possible with smaller engines ?

Nitro RC engines work very much like small diesel 2 strokes. These are only up to a couple of cc though. I'm sure a reasonable 2 stroke diesel could be done, but why?

Bet that's a revver

There has to be performance advantages from spending more time making power, than sucking and exhausting like a 4 stroke.
If not, why does it work on massive engines and not small ones ?

Probably becuase there is much long time for the fuel air to burn before its all dumped out the exhasut. Aslo coss of the VERY slow RPM you need as many power strokes as you can!

In smaller 2 strokes everything happens soo fast that you cant get complete burn inside the cylinders.
