Cause ME's are Cool!

[KingWalrus]

Hey, I'm sure more of you guys deal with CAD on a regular basis. Got any drawings/models that you think look cool? I thought this was pretty slick. This is a model of the DOHC 14.9L diesel head that I am working on right now. I made several of the surfaces/components semi transparent so you could see a little of the inside of the casting.

:yeah:

A short explanitory:

The kinda salmon colored shape on the left is an exhaust port. The blue shape right next to it is part of a secondary water jacket system that cools the exhaust side of the head. The big three white holes facing you are fuel passages. The giant holes at the top side of the head are, you guessed it, for the camshafts. The circular arcs at the very top are for the rockers.

i have never heard of this CAD you speak of ;). awesome model, ME's are the coolest :yeah:.

Dude that is really cool!!

[KingWalrus]

I'm a retard. That port that I pointed out was the intake port, not the exhaust. Doh!

Also, notice that you can see the oil passages that supply the cam bearings and rocker bearings. Pretty damn cool, imho.

thats awesome dude!

Is that for a Semi? 14.9 liters is huge! What type of power does something of that size produce?

I swapped a 14.9 liter in my go cart.....:yeah:

Lol, no idea how that would work!

Wow.. pretty pastel colors ;)

Pretty sweet... I have absolutely no idea what program that is but sweet nonetheless... what are you going to do with said engine???

[KingWalrus]

We are starting a new reman line on those heads at the plant where I work. Phase I is done, salvage and disassembly. At the end of stage I, the heads are basically clean bare castings with the injector sleeves and valve seats still intact and the combustion face milled. I'm working on stage II. This is where the old injector sleeves are cut out, new ones installed and cut, valve seats are ground, all other parts are machined and installed, and head is prepped for installation on the engine. At the immediate moment, I am finishing up the design and construction (off site) of a leak test machine that:

Picks up the head
Clamps to a plate with seals to block off coolant and fuel passages
Pressurizes said passages
Performs leak down testing as well as gives visual feedback on where the leak may be

Sounds easy enough, but when the head weighs 450 lbs, lifting and reorienting it is challenging. The operator safety aspect of the design is rediculous.

Sorry for the novel. That's what I'm doing with the heads right now.

Oh, and the program is ProEngineer Wildfire 3.

Is that for a Semi? 14.9 liters is huge! What type of power does something of that size produce?

Yes, semi trucks and other industrial applications.

The engine is offered in several different power levels. As far as I know, the only difference is in the PCM programming and boost levels. The highest output version is rated at 575 bhp and about 1900 lb-ft of torque.
:cool:

The largest cylinder head I've worked with was one that goes on a 45L V12. Each cylinder has its own head, and each of them weigh about 180 lbs. :eek:

Lucky me, I got to design lifting fixtures to pick up the heads. Whoever had previously made them didn't keep any drawings or backups. Well, it was only a matter of time before the existing fixtures were somehow lost or scrapped.
