Mmmmm Gotta engine porn
I like em big
One 4 stroke piston and connecting rod
What is it?
The picture of the bare cast block are wartsila 12V W46's the piston and con rod are for a wartsila 64 (most powerful 4 stroke engine ever made) the last picture is a crank shaft with big ends installed for a 18V w46
Incase you wondered I work for wartsila this is one of our factories in Italy
We make the most powerful engines on the planet (14 cyl Sulzer flex 96)
How do you balance a crankshaft that size?
By application of engine balancing theory, rather than by putting it in a giant spin balancer, I would imagine. Besides, an engine that size is a slow turner, so being a little off shouldn't be a huge deal.
On the contrary. These crank shafts are static balanced. A lot of the calculation is done before but when a new design is made there are a lot of balancing corrections.
The W46 spins @ 514 or 520 RPM depending on the application and these engine produce 1.25 Mega watt per cylinder and this is for a 18V so 22.5 Megawatts of output or 31,500 HP @ 514 RPM May not seam like much but in terms af relativity the piston speed is the same as most engines. 13,000 RPM seams like alot on a bike but when the piston only moves 50mm it really ist traveling that far Vs a large engine like this where the piston is traveling 600MM or like on a slow speed 2 stroke 2.5m
This actually a competitors engine a bit smaller then ours but you get the idea
Someone is already thinking about how to build a motorcycle around that.
Why? I am trying to figure out how to build that into a garage or a house!
Is it really nessecary to chain it to the trailer its on? that thing is so big that if it moves, its gonna take the trailer with it!
Usually if the load starts to move it will take everything with it there have been issues with the road falling apart under the truck due to the massive weight
And heres a quick history lesson if you enjoy that kind of thing
