Hi colleagues!
There is the second run of my new engine.
I beg your pardon there is still no accurate measuring.
And the quality of video is poor because the engine is still far from completion.
Engine bore is 83 mm, stroke is 64 mm as cold as hot piston.
Free run is at about 1000-1200 rpm
At the mid of the video the engine powers two car lamps each
5 Amp 14 volt. Total is 140 watt of electrical power. Tacking into account an efficiency of the old alternator is 40% (was measured earlier) the engine produce about 300 watt of mechanical power.
The whole second try was conducted at 2 bar of additional pressure (mean pressure in crankcase). Pressure in working space is higher because of sealing lips. I estimate mean pressure as 4.5 bar absolute. When I assembly good loading equipment I will increase the pressure.
The current result falls near points that was calculated by
the SNAP calculation soft at https://sites.google.com/site/snapbur...
I will post next videos when there will be something interesting.
Thanks for watching!
Повторяем попытку...
