what is "variable geometry turbocharger"?

I'll see your Big Mofos and raise you a reel of CRAZY MOFOS.

Off the top of my head, I would say that the vanes inside the turbo, that catch the exhaust that drives the turbo are adjustable for pitch. To catch more, or less, exhaust, to spin the turbo faster, or slower.

Like a variable pitch propeller on a plane.

Or maybe the driven blades that move the intake air are variable.

Gravdigr 06-08-2017 04:44 PM

Oh, yeah...That other set of vanes.

maybe i don't know. but that fucker is spinning at 100,000 rpm, it seems like you could find another place to fiddle faddle the amount of boost that wouldn't involve such an insane amount of reciprocating, no, washplating machinery.

I'm gonna look it up.

Ok, looks like they're changing the geometry of the inlet air, either with a sliding wall which reminds me of a choke plate, or by using vanes on the inlet (turbine side, exhaust stream) that can change their angle and direct the flow toward different places on the turbine blades (not the compressor blades on the "inlet" for the intake to the engine.

The one at the link has a bigger bucket.:3_eyes:

The 240 ton Caterpillar 994K has 12 foot tires. The top of the cab is 23 feet off the ground. The bucket can scoop 45 tons at a time. The bucket is 41 feet high when raised. It has a 72 liter engine that makes 1850 hp. The 994K has a 5,678 (5,6,7,8 :eyebrow:) liter fuel tank.

Just because you're going camping like some middle class worker bee doesn't mean you can't be cool. ;)
