Cooper-Bessemer GMV-10 Scavenging Air

A follow-up video to my Cooper GMV10 video, just to explain the basics of these engines.
The different Cooper GMV's I have operated are GMXD, GMXF, GMVA and GMVH.
All share the same V-10 design, but each has different scavenging air systems.

Excellent engines. I manage a GMVH and a GMVA. We also run some GMVGs I believe

The longevity is astounding, the compressors at our plant run 24-7-365, and they need regular ignition components replacement, but other than that it's crazy how long they run.
Cruise through the compressor building they are just whomp, whomp, whump pounding away.

Thanks for the explanation. This is the first time I've seen these particular engines, their construction makes sense. What percentage of the gas is used as fuel?

What percentage of the gas is used as fuel?
If you mean what is the air fuel ratio I'm not dead certain?
I can tell you that fuel is basically proportionate to the air that the engine is able to compress, and load on the engine dictates much of that.
If the load increases, the governor automatically compensates to increase fuel, in order to maintain engine speed. Air intake being driven by the engine output will then increase as well.
The significant factor in horsepower/fuel consumption in these units is ambient temperature.
Warmer air is less dense, so much harder to increase the air mass to the engine, and they will produce less horsepower. Unfortunately, this state can also lead to detonation, a serious problem in the 2-stroke scavaging air engine. Detonation is air fuel ratio that is too rich, which is usually due to high ambient temperatures.
Detonation means that instead of smooth combustion, the engine experiences explosive ignition of the air/fuel mixture. When the air/fuel mixture explodes, this can damage the engine, heads, head gaskets, supercharger etc...
The opposite happens during cold weather. Then because the air is denser, you can compress a far higher mass of air into the engine, fuel automatically ramps up, and then the horsepower output of these engines can increase significantly versus horsepower output in the heat of summer.
I hope some of that makes sense.

Jeepers I'm not certain?
We have 2 gas compressors running and 1 propane compressor, plus numerous heaters for process.
Combined we burn approx 41km3 fuel gas each day.
I believe the Coopers burn around 5km3 each pre day?
