that thing is a monster... its quite easily 1/3 the size of our whole injection pump itself... if you could do a side by side comparison that would make a great avatar lol

Instead, in this engine the top of the connecting rod attaches to a "crosshead" and a long piston rod then connects the crosshead to the piston. This lowers the sideways forces produced by the connecting rod and is absorbed by the crosshead and not by the piston. Sideways forces are what makes the cylinders in an auto engine become oval-shaped over time.
very interesting... i wouldn't want to do an oil change on that thing... :shock:
108,920 hp at 102 rpm ummm... that is many many horses!

I guess you just need to replace the guides when you rebuild the engine?

thats a really interesting setup...in reality the crosshead guide wear limit could be virtually unlimited, and still provide excellent wear reduction in the cylinder walls... i wonder which other companies are going to be streamlining this new technology...

New technology? I don't think so. The very earliest steam engines used crossheads so that they could seal the piston rod and make the engine double acting. 2 stroke marine diesels have always used a crosshead design since inception (early 1900's?) so that the under-piston scavenge space can be sealed from the crankcase. Nothing new there.
Crosshead designs would produce engines too tall for automotive use.

couldn't a design like the chrysler slant six be used? they had long strokes so they were tilted to fit the engine under the hood. ........just an idea
