No........

I'm lost!

Tricky but obvious when you see it!

After testing every position of Lambda sensors I found the most consistant results are had placing it right at the start of the
perf in the muffler.
This seems to " average " the reading over several cycles.
At the mufflers other exit end the sensor is contaminated with fresh air , being pulsed back and forth by the wave action
reflecting off atmosphere.

I wonder if its a practical possibility .... interesting....

Interesting discussion paper on High Temp Gas sensing for Automotive use, including 2 Strokes:
https://www.researchgate.net/publica...ons_-_a_review

If anyone can possibly do it practically, I'm sure you can.

Wobbly, what sort of temperatures are present at the start of the muffler?
If under say 600C, current sensor technology is more than up to the task.

Lubrication and cooling bigend connectionrod.

As my bigend seized i´m about to rebuild it with a fresh rod, but i´m thinking maybe leave the axial plates/discs on the bigend and guide the rod in the piston instead.
I figure i might loose some friction also, and by this not build as much heat in the bigend.
And when having no axial plates/discs there are more space to cool it and lubricate it.

Is it a good idea?

Yes, a very good idea!

[Muhr]

why is not a MAF sensor a good option?

why is not a MAF sensor a good option?

Probably would be if it was at the entrance to a large well sealed air box.

It would probably work particularly well with a multi cylinder like the Suter MMX500 road racer.

Use the MAF as a 24/7 flap valve??

Used one of these:

In the stacks of wood stoves, far outside its rated operating temp, for 150 mins, with results not dissimilar to dedicated industrial units.

Cheers, Daryl.

Would like to see your evaluation on this, if you proceed.

RG500 has same arrangement. Be careful with washers material and arrangement as upper bearing is wider than rod.
Hi everybody, been occupied for time beeing with racing, broken arm, racing WITH broken arm, and v16 diesel burned crankshaft

Might be Rocket Science:

NASA is looking for partners to develop & use these in new applications.

Bleeding Edge 2 Stroke technology might be appropriate, after all there is a technical bonding link, way back to Walter Kaaden, V-1 & 2's & WW2

cheers, Daryl.

PS. Don't mention the War! I did once... but I think I got away with it!

Hydrocarbon sensors available in NZ for less than 20 Kiwi Dollars.

http://www.etech.kiwi/4310-gas-sensor-hydrocarbon/

At that price you could replace them after each Heat (pun intended).

Cheers, Daryl.

most conventional engines has the guiding discs on the big end but suzuki had several engines with guiding discs on the small end as well. if you remember the lt250 and lt500 qaudzilla

As was the RGV250

I´ll modify the piston to accept the rod with correct clearance, as is now, the rod is wider then inside of piston
