From your first Post: - [ i]"a)The process of the combustion of the mixture begins before the piston arrives at the “top dead point” and it means that the movement of the piston to the ”top dead point” is counteracted by the total pressure: the sum of the degree of the compression, and the incr...

Serguie you are obviously a keen young Engineer who is looking for good ideas everywhere and trying to put them together, so I congratulate you on being interested in the subject and spending time researching it. Your English is much better than most English peoples foreign Languages and you are obv...

I read the original Post, but it appears to have been translated using Google Translate and the meaning is not clear to me at all. Your later Post is written much more clearly. I do not I see how it will be mechanically more efficient than a traditional engine. In a normal Reciprocating engine, alth...

That last 20 per cent, is Urea ammonium nitrate also known as Pig's Piss or Pig's Urine.

..and PV to the power 1.4 is also a constant where 1.4 is the adiabatic index for air / Nitrogen. (the ratio of the specific heat capacities at constant volume and constant pressure) Engines can easily be made with a higher thermal efficiency (Carnot efficiency) by increasing the peak pressure and t...

Do you know anyone who could make a better engine in Glass?
As for lube, maybe he sprayed Teflon on the bearing surfaces while they were red hot or maybe just a drop of silicon oil on the moving parts before starting.

I shared the link to the Glass Steam engine with a Member of the Institute of Stationary Steam Engines, who reciprocated with the links below: - 1) Not a glass engine, but an engine in a glass box (I've seen it back in 1992): https://en.wikipedia.org/wiki/Steam_clock https://www.atlasobscura.com/pla...

Scandinavia, there should be a diagonal line across the "O" but I can't find it on my keyboard. I believe they used to use it before they went Metric.
I only came across it once.

Merlyn,
You are heading in the right direction for the Rohr threads, keep going East.

BP

Ah Merlyn,
You are over thinking, I believe Rohr threads were available in all flavours, just like Whitworth, Metric or American Course.
BP

But where do they use Rohr threads?

"The hull of warships is typically cold because of the outside ocean temperature, he said." There is a substantial layer of insulation on the hull, at least there was when I did trials on them. The interior of the ships is climate controlled, temperature and humidity are closely monitored ...

This brings a whole new meaning to having an empty Gas tank and running on fumes!
