Tegheim - Home made 4 rotor Wolvo 142

Tegheim · 05-11-2013, 01:31 PM

Have worked alot on these rotors this week. Totally 32 times on 4 rotors in the machine.

Tegheim · 05-30-2013, 09:36 AM

I bought a bunch of new rotors. How do I comfirm that they are 9.7:1-compression?
I have weight them, but all the newer rotors have the same weight. The 28cc in the comb-chamber are kind of tricky to check, or?

Your build up is awe-inspiring!

Today I get to play with the big boys :-)

This is one of the best build threads ever. Thank you for sharing this.

Havn't done much lately, but have done some with the steering, the wattlink and finally some on the intermediate-plates.

This was a LEGO i designed

And this is how that goes in the car.

Here the intermediate-plate is prepared for the bearing

Just staring at that front end.
Nice work.

Amazing build. I need access to some of those tools! Just the raw material for the engine would break my budget, haha. Can't wait to hear the startup video.

take a caliper and a flat piece of metal, mic the metal and zero out the gauge. lay the strip over the pocket and measure the depth of just the pocket and it should be very close to 10.85mm in depth and have a machined relief(the deeper the pocket is, obviously the lower the compression is). this is the measured depth for the 9.7:1 rotors.

turbo rotors also have a T stamp embossed into the oil relief vein area facing the center iron, n/a rotors have no T stamp, just a I and II for front and rear(which accompany the T on turbo rotors).

that said, the quickest and easiest method is just check the oil galley in the rotor for the T stamp(or lack thereof in this case) and make sure the rotor has a machined pocket for the series 5.

if you somehow managed to get renesis rotors they're a little less conspicuous with their scallops and thick side seal lands.

Neat!

Have lately spent some time with the porting of the engine. Most in SolidWorks, but also in reality.

Thought I run with V-band instead of what is in the renderings. However, I must turning one half of the V-band myself, and it seems difficult to find the measure of it.
If anyone has seen it, or know how they should look like, I am receptive :-) Happy to metric! The tubes I intend to use is 50x2, ie 46mm internally.

An engineering marvel! very impressive!

Tegheim · 11-09-2013, 12:59 PM

Continued today with the trash-housing.
Did a test sleeve in the cnc-lathe. I am very satisfied with this. Have minor improvements to do with the real ones later.

agreed ... and yet still i still find the words so bloody inadequate.

I have been thinking about the intake. I would want to have tapered runners, but because "someone" decided to lower the entire body over the frame, there isn't much space above the engine.
This means that I have to make a turn on 156.5grd pretty tight around the engine and land on the block. The options are to cast runners in plastic, carbon fiber or aluminum perhaps?

Today I continued to mod my intermediate irons for more bearings.
First I layed a the intermediate and clamped it. Then either front or rear iron onto to indicate the centrum.

Machined two new very tight dowels. As tight as possible.
Even then you can move the plate 0.015mm in both directions. I alinged in the middle of the play.
