So, what you are showing off here, is a 120 year old steam engine, using variable valve timing to throttle itself, all done mechanically..... And BMW thinks it is so awesome with its modern electronically controlled, problem plagued system in gasoline engines now? HA! This is so much more awesome! Thank you so much for posting this!!! Need to show this to a friend that has a BMW with one of those very gasoline engines.....

Since a While I work on the "Täggelibock" On the lake of brienz. Its switzerlands oldest Motorship. Its a ship from 1909 which is almost as old as this steam engine. It is still operational by the way I am an engineer there, and the Oiling caused some PTSD not gonna lie. I have to oil the motor every 30ish minutes, its crazy

Jim Sim...during the age of steel there were ..boiler makers ..engineers .. 100 s of other trades one trade is very overlooked and more important than the rest ..that was the oiler ..he had to know about all types of oil ..viscosity ..tolerance to heat ..correct use piston ..crank ..controll shaft ..this was an apprentice learned job with some education when employed by big companies eg shipping lines railways big factories usually weavers some steel industry .some American teams still use oilers in their names ...

Great to see the inlet valve gear and the regulator in action and have it explained so well! You really have a thing for breaking down the complex mechanism and present the interaction of the parts. Brilliant!

Fantastic video! I love learning the history of various steam engines - and I have to say the one in this museum is in STUNNING condition! I LOVE seeing the inner workings of machines and technology, so steam trains aside the steam engines and beam engines of yesteryear are RIGHT up my alley!

Your videos are somehow always immensely entertaining and informative; explaining the basics of the mechanisms while also showing the complexities therein. Great work!

17:08 "The valve open in short bursts" This is very important, by letting some steam in and then closing the valve, the steam, which is pressurized, expands, giving energy (work) to the piston. It is that expansion that does the work.

@MatthijsvanDuin 2 ай бұрын

Ehhh, no. Using short intake bursts actually reduces the amount of work it can do (because the pressure difference across the piston decreases during the expansion), but it greatly increases efficiency. You can also leave the intake valve open, putting full boiler pressure on the piston, for nearly the entire stroke and then let it all out in a short burst at the end of the stroke. This can nearly double the amount of work done per stroke compared to burst-intake mode, but it also dumps a cylinder full of high-pressure stream out the exhaust at the end of each stroke, which is a huge waste of energy and water. In this case all the steam expansion happens when the exhaust valve opens and does no work on the piston, the energy is instead converted into impressive chuu-chuu sounds from the exhaust stack. The Stephenson valve gear he explains at 13:45 allows an engine to operate in either of these modes or anything in between. This is used in stream locomotives for example, which use the inefficient max-power mode (power reverse bar "in the corner") to have max torque available to get the train started, and then as the train picks up speed the engineer will gradually move the bar towards the center to get short intake bursts for efficient operation (and reduced wear on the engine).

So steam technology had variable valve lift around 100 years before car engines ... impressive.

When we are doing Eng 101 and the Math-Physics accompaniment of the Calculus of rotation, it's a subtle exposure to Virtual Work as a wave-packaging pulse-evolution differentiates integration here-now-forever, ie we're learning by what is self-defining Actuality of QM-TIMESPACE In-form-ation. This set of historical developments in energy machines is the core of understanding reality. Thanks.

Wir scheinen ja doch recht ähnliche Videos zu machen. Was ich vorschlagen könnte wäre die Basler Papiermühle, da hatte ich selbst schon öfters drüber nachgedacht aber ich denke mal dass dein Stil von Videos dafür deutlich besser geeignet ist, um die einzelnen Arbeitsschritte zur historischen Papierherstellung zu erklären. An und für sich sitze ich seit knapp zwei Jahren auf unbearbeiteten Aufnahmen von der dortigen Linotype-Setzmaschine, für die ich Erklärungen einsprechen möchte weil das nur mit Untertiteln einfach nicht zu machen ist. Aber selbst dafür hab ich in zwei Jahren nicht gebacken bekommen, mit meinem Skript zufrieden genug zu sein um das aufzunehmen. Btw. hat Valters mich erwähnt als ich da war? Grüße könnte ich ihm ausrichten, ich bin auf WhatsApp in Kontakt mit ihm, mehr oder minder zumindest.

Freut mich sehr, dass du mein Video gefunden hast :-) habe dich sofort abonniert. Valters hat mir von dir erzählt und mir ein Video von dir gezeigt, super Kanal! Respekt, an eine Linotype-Maschine hätte ich mich glaubs nicht dran gewagt - das wären hunderte Stunden Arbeit in Vorbereitung, Verständnis, Scripting, Filmen, mehr Scripting, noch mehr Recherchen und dann Schnitt. Ich kann dein Problem also abslut nachvollziehen. Wenn du magst, können wir Valters bitten, uns gegenseitig die Nummern zu teilen. So müssen wir keine privaten Kontaktdaten im öffentlichen Raum posten, was meinst du? Liebe Grüsse!

@@sandro-here Kannst ihm gerne bescheid sagen, das mit den privaten Daten sollte ja eigentlich gesunder Menschenverstand sein. Privat darf er meine Nummer gerne an dich weitergeben. Kann sein dass ich nicht sofort antworte, ich bin beruflich grad etwas eingespannt drum hab ich Valters auch noch nicht selbst gefragt. Aber an und für sich kann ich mit Papiermühle und/oder Linotype gerne über WhatsApp weiterhelfen, ich bin halt nur etwas inkosistent darin wie schnell ich kommunizieren kann. Btw. falls mal Interesse am Hamburger Museumsschiff Cap San Diego mit dem großen Zweitaktdiesel besteht kann ich auch gerne helfen, ich bin da selbst aktiv zugange.

It doesn't look like you have large enough boilers to supply a 300 HP engine.

@WhyAyeMann 2 ай бұрын

The generator isn't really loaded up that much, so the engine never really gets any where close to developing 300 HP in preservation. The small boilers are able to effectively supply steam because the engine is through steam very slowly and efficiently.
