This is the OT. Mine has 25 cylinders, 13 superchargers, and 3,200 HP

only 3000HP? You would think it would turn out at least 5000HP

re: Check out this giant Truck Engine. 24cyl, 12 Superchargers 3,000hp
yeah, but it's probably putting out 6,000 #ft of torque

holy shit,did you see how under driven those 8-71's were?
You could turn em by hand that fast almost.

re: Check out this giant Truck Engine. 24cyl, 12 Superchargers 3,000hp
sorta common in shipping and generators.

quote:

Two-stroke internal combustion engines are more simple mechanically than four-stroke engines, but more complex in thermodynamic and aerodynamic processes. In a two-stroke engine, the four "cycles" of internal combustion engine theory (intake, compression, ignition, exhaust) occur in one revolution, while in a four-stroke engine it occurs in two complete revolutions. In a two-stroke engine, more than one function occurs at any given time during the engine's operation.
Intake begins when the piston is near the bottom dead center. Air is admitted to the cylinder through ports in the cylinder wall (there are no intake valves). All two-stroke Diesel engines require artificial aspiration to operate, and will either use a mechanically-driven blower or a hybrid turbo-supercharger to charge the cylinder with air. In the early phase of intake, the air charge is also used to force out any remaining combustion gases from the preceding power stroke, a process referred to as scavenging.
As the piston rises, the intake charge of air is compressed. Near top dead center, fuel is injected, resulting in combustion due to the extremely high pressure and heat created by compression, which drives the piston downward. As the piston moves downward in the cylinder it will reach a point where the exhaust port is opened to expel the high-pressure combustion gasses. However, most current two-stroke diesel engines use top-mounted poppet valves and uniflow scavenging. Continued downward movement of the piston will expose the air intake ports in the cylinder wall, and the cycle will start again.
In most GM and EMD engines, very few parameters are variable and all the remaining ones are fixed. The scavenging ports are open from about 45 degrees before bottom dead center to about 45 degrees after bottom dead center (this parameter is necessarily symmetrical about bottom dead center) and the fuel is injected at 4 degrees before top dead center. The remaining parameters have to do with exhaust valve timing, and these are set to effect maximum exhaust scavenging and maximum intake charge air, and these two parameters are not necessarily symmetrical about top dead center. A single camshaft operates the valves and the Unit injector, using three lobes: two for exhaust valves (ether two valves on the smallest engines or four valves on the largest; and the third for the Unit injector.

They measured at the wheels. Transmission loss.

Does that engine even lift?

What do you mean by lift? Like lift up in a wheelie? I doubt it, looks like they have to add 8' to the front of the truck just to install it.
The video is from 2010, and I haven't been able to find the final product.

found this pick from 2011

Looks like the engine in my Honda Civic hybrid.

A V-12 71 NA is like 450 HP on a good day. You couldn't push much of a crew boat with that.

Because running them at any speed would blow them up. It only "needs" 3.

Do you have to drive with your head out of the window or does it have something like a front camera or periscope?
