Hi Muhr

The software code for optimization of Autodesk and many others is made by Altair.

The other main player in optimization is Ansys.

Each known part can be made lighter using this approach

But i'm a coward, should be able to take 5-8g if you have some balls

If you try to get away without welding, then you seems lose a lot of weight gain.

Of course, what you wanted is the opportunity to simulate a whole rotation with all oblique loads. but we deadly may have to wait for that opportunity for a while.

I am interested in your EFI system.

If it can, how does the Aviamechanica deal with this changeable air flow situation below 25% TP in a two stroke engine?

We used before ecotrons, but had problems with system openess and sometimes it burn out. So we developed our own. We can develop electronics of any level of complexity, if it worth. Says in other my company sharing the same building we make avionics http://uav-siberia.com/en/catalog/avionika/

In our EMS project we decide save on software development. So everything what can be programmed in http://www.tunerstudio.com/index.php/tuner-studio is available. All algorithms and data tables.

The very specific questions should be adressed to our EFI engineer. I will pass your message to him

Ignition part of our system could give you much more tuning options than Ignitech. And using 158 grammes Nissan Denso spark coils give you possibility burn out

With Ansys it is already possible. You can give as piston pressure vs angle for each rpm and see stresses picture in each moment. You can google for transient crankshaft analysil in Ansys.

Awesome i want that.

I got a question concerning sparkplugs:

I wanted to draw a head for a 50cc engine but the 14mm Sparkplug is very design-restrictive. Has anyone ever tried a smaller thread diameter than 14mm?
With a smaller plug it would be possible to cool more area of the combustion chamber with water.

Emot uses 10 mm plugs on its 50 cc racing sets. KTM uses 10 mm on various MX-models. I intend to use 10 mm plugs wherever possible.

Rob asked me about the nozzle in the stinger of the GP-NSR 110 that is in the sim.
Here is the assembly that I use, makes it real easy to change the insert.
In this case I have drawn the stinger as 25.4 ID - 1.6mm wall tube, with a 23mm ID insert , that is 20 long with a 45*chamfer on the exit.
This I have tested on the KZ2 engines and seems to work the best.
You could go to 1.2mm wall stinger tube and test that with a bigger OD insert.
This would have more effect on the return wave coming back from the muffler,and may make better power.
A couple of spring hooks and a header spring make the joint flexible and helps prevent weld cracking in this area.

Great, thanks for that Wob.

Looking at the spec of that Denso Iridium plug - it does not appear to have a resistor element.
This will most probably cause issues with noise when using a digital ECU like an Ignitech.
I have used spiral wound core plug leads with just a resistor cap, and no plug resistance , and this worked with no crashing of the ECU.

The SmartEMS light in aluminum milled case start 205 usd
wire harness with all connectors 68 usd
5-axis milled throttle body starts 110 usd.
Remaining sensors possible get from us or from any local shop which sell automotive or ATV components.
We can prepare complete instalation kit by customer specs.

I would love to see more photos of all the bits and pieces available posted here.

Please have a look. At moment we have most of documentation in Russian, but going to translate on English, German and French soon.

40cc model engine

Some components looks rude, but they are more reliable than nice looking parts. We dont tested EFI at higher than 10000 rpm, but dont think it will a problem, espetialy using few nozzles.

Note: O2 sensor can be used in learning mode and disconnected afterwards. If correctly placed survive in 2-strokes for about 150 hours only.

Easiest way to get additional info is push me by e-mail
