Dandy Dave Posted July 24, 2023 Author Share Posted July 24, 2023 (edited) Here's another Video I filmed. The engine ran flawlessly for about 5 Hours which is a full tank of gas. It only quit when it ran out. Edited July 24, 2023 by Dandy Dave (see edit history) 8 Link to comment Share on other sites More sharing options...

Restorer32 Posted July 26, 2023 Share Posted July 26, 2023 I believe there is at Otto engine in the Rough And Tumble museum collection in Kinzers, PA. 1 Link to comment Share on other sites More sharing options...
drhach Posted July 26, 2023 Share Posted July 26, 2023 In what application were these typically used? It doesn't look like the typical "hit and miss" engine that you'd see out in hay field. DId these power belt systems in shops? Link to comment Share on other sites More sharing options...

Guest Posted July 27, 2023 Share Posted July 27, 2023 (edited) Nice videos. Fred Starr in the UK has written some interesting papers on valve design. There is a free to access article here: https://fredstarr.com/wp-content/uploads/Chapter-22-Starr-Valve-Cooling.pdf There is a more detailed article here (paywall): https://www.tandfonline.com/doi/epdf/10.1179/1758120612Z.00000000013?needAccess=true&role=button Edited July 27, 2023 by John E.

This particular engine was thought to originally power a generator as the size of the flywheel and pulley are key to powering that type of unit. Many did power over head jack shafts in shops to run machinery or pump water. Link to comment Share on other sites More sharing options...

Valve development has come a long way. A lot was done in WWII on aircraft as the exhaust valves were the weakest link and lead to engine failure. Sodium filled valves were found to help.

wayne sheldon Posted July 27, 2023 Share Posted July 27, 2023 A lot of early Otto engines were used to power mechanical looms used in the textile industry. They made it possible to build factories that previously needed the "perfect" river to be run by water wheel. The Otto engine also had an advantage in that it was easier to regulate the speed than was a water wheel. D Dave, Interesting aside about the evolution of valves! 1 Link to comment Share on other sites More sharing options...

Yes, and it wasn’t until the development of the first fast acting and effective waterwheel governor by Alvin and Nathanial Lombard in 1897 that the Development of hydro power to generate electricity became wide spread and practical. 1 Link to comment Share on other sites More sharing options...
