Digital file - 6 cylinder engine geometry

wevoid · wevoid's Garage

For those in the CAD world, does anyone have a basic block architecture file for Porsche 6 cylinder engine - reasonably complete? (inc. cooling, intakes)
I am not looking for a full working assembly model of cranks cranking, pistons pumping etc.
We are laying out a porsche 6 cylinder powered vehicle and locating an appropriate digital engine model would save us a bunch of modeling time and agro.
I am willing to negotiate in respect of the value of the right type of file - if you are the author.
*.iges, *.par, *.prt, Parasolid, others, what have you got?
This is shaping up as a fun project and I would be willing to involve other designers, pro or amateur if any correctly experienced PPBB's heads are looking for project vehicle design work.

Regards

Interesting.

I don't have any 911 models for you, but if you can't find any, email me. . .. I happen to have a micro-scribe for digitizing this kind of stuff. Also have a license of Solidworks and access to various 911 motors.

BTW, How much detail are you looking for, in the external. . and of what type of 911 motor & intake?

island911,

We need an accurate "envelope" model.
Model could be a generic air cooled 6, 1965 to 1989. Intakes are most likely to be individual stacks, so MFI, Carbs or non OE throttle bodies would all work.
Bellhousing area needs reasonable accuracy, although mostly as a reference plane. Cylinder heads, rocker covers accurately located and proportioned, same for chain housings. Fan housing would need accuracy, but fan and alternator not really.
Does not need plug wires or other electrical systems.
Oil inlet and outlet need accuracy.
Exhaust ports need accurate location and planar location ref crankshaft.
The underside of the crankcase needs to be accurate.
Would like to work +/- 1mm - we will manually correct the exacting details. Is this practical with your digitizing equipment?
Solidworks files are OK, We run Solid Edge.

Regards

Hayden

If you find one I'd be interested ad well. Maybe Souk knows someone.

I'd like this for a tattoo!

yeah me too!

I haven't come across any 911 engine models, but have come across a very cool 917 engine model.

If you can speak Japanese, you may find someone who has modeled a 911 motor. (they seem to be big into this type of thing.)

The manufacture of the digitizer claims ±.23mm; I find ±1/2mm is usually closer to what you get. .. . but then, I'm usually digitizing plastic items which tend to be a bit softer.

Hayden,

Pete Weiss, an employee of Sherline Inc. is/was making a 1/6 scale running model of a 6 cylinder Porsche engine.

You might be able to contact him. I do not know him, I just read about him in one of my Machining/Engineering books

If you can get a hold of one of these Marushin 1:8 scale Porsche 911 Carrera RS 2.7 engine it might make digitizing a little easier

Mike *that* is cool!

Though I've got to say, it would be at least 8x more accurate to get the dimensions off the real thing.

Nope, don't know anyone with a CAD file of a flat six, Terry. Wish I did....and our CAD guys would take years to do that

Mike,

Thanks for the link.

island911,

I agree it would be better on a full size unit - especially as a point cloud exercise.
Do you want to email me and we can discuss privately the feasibility of doing reasonable envelope model from an appropriate motor?

Regards

Hayden

LOL at the tattoo! You guys are hardcore.

You could use the graphic from the 2.2 rear window decals. Rear engine - 1/2 on each butt cheek!

targa911S · 07-31-2003, 02:04 PM

on my skinny a$$ it would look like a Briggs and Stratton!

Hayden,

Can you let me know if you find these files? I'd be willing to help absorb some cost as well since I could use the same files to help me with a 1/4 scale 911 motor that I'd like to build one of these days.

Currently the only 911 engine part I have that I could model is an early 2.0 head (911 engine)

No Solid Edge experiance but I have played with SolidWorks (2001)
Daily used software is Pro/E Wildfire which should import/export files fine with SE.

I was just kidding about using the scale model for your application, who knows how correct it is and the resolution is too small to get an accurate rendering?

Mike,

No problem, I will keep you in the loop once we drop off the BB.
I expect the model will be created as a coarse envelope, not by assembly of individual components. That would be great but uneccessary for the basic packaging excercise and almost certainly impractical for both time and financial reasons........ The perfectionist in us all wants the most accurate model.

Regards

Hayden
