Opposed Piston Diesel Engines Are Crazy Efficient

I have read about post WW2 installations on locomotives…while this is very complex with a supercharger and turbo, there won’t be reliability issues in a valve train; with a wide & flat, I’m assuming powerband, it certainly could be efficient in trucks & vans; hot rodding probably is a not and that’s esoteric anyway…a shipbuilder in Mobile I think actually built the entire locomotive…only one completed for the GM&O…thanks

I’m mechanically inclined but even I can see the ability to easily control combustion is a plus; I also like the two stroke simplicity…good luck to the developers…

if that thing gets desyncronized for some reason it has to be a nightmare to fix!
But it looks like a very cool idea

Well, if the cams and crank gets desynchronized for some reason, it is a nightmare as well.

Not a new idea at all . The WW2 sub I served on had these. Makes for a lower engine.

It’s probably one of the simplest engines to work on since you only have the two crankshafts to sync in and that is done by gearing it together.

Fairbanks Morse 38f been around for a long time about 700 hp loud as …..

Isn’t (or wasn’t) there a version of opposed-piston engines with three cylinders (6 pistons) arranged in a triangle, with three crankshafts at the apexes (apices?) of the triangle? I think it was used aboard ships, or in one of the world’s navies.
Here it is… the “Napier Deltic” engine.

hahaha..compete defective…the cylinders never move with the same speed and powere in same direction…

How is the diesel fuel pressure created?
What is the emissions ?
Looks like a more efficient engine.
Imagine this engine attached to a generator,powering 4 wheel electric motors.
MPG would be incredible

Found out these existed in junkers jumo planes…never understood why since diesels have such low rpms…but the napier deltic sounds the coolest

I sent to them an idea for one kernak instead of the other and you did not accept the idea. And I still think it’s better than this and without gears

incorrect, to much moving parts meaning inefficient

yeah yeah we know…. electric engines are best right?
