We make steam every morning while preparing our morning coffee. But how can it be used to move this massive machine? In this episode, we explore how engineers designed steam engines to turn fire, water, and steam into tremendous amounts of force.
This video series is the winning project of the Europeana STEM challenge 2019 and was awarded funding for its production. I’m grateful to the Europeana team for support in creating this series and providing invaluable educational resources.

There isnt much else to say. Except for the valve gear. On earlier engine, there are two sets of essentrics, 175-180 degrees apart. One is for forward and the other is for reverse. Later link motion valve gears allowed steam tk be cut off at higher speeds, which allowed smaller amounts of steam to use much more energy and saves more steam from being spent.

Same, there are some interestring details, like latest Czech locomotives have three pistons (ukposts.info/have/v-deo/n6pjrIGJgJuZpZc.html), two chimneys, Trofimov valves that are freely moving on the rod when steam pressure is not applied (idle) reducing moving mass, there some interesting details like superheating steam, water pockets in boiler and last part which i do not understand is kinematics of linkage system (to make it worse, it has to work with dumping and train must be able to turn ... and someone had to design it without computers more than 100 years ago. It surprises me that people were able to design very complicated mechanic machines whereas today we are trying to replace everything by electronics with no moving parts (take drone with complicated and rapidly reacting regulation and simple brushless motors vs helicopter with tilting rotor blades)

What you have shown is a *Portable Engine* , not a traction engine. The main difference is that a portable engine lacks a drivetrain, so it is not self propelled. They were moved by horses to wherever they where needed. Traction engines came later when portable engines were modified or redesigned with steering systems, fuel and water storage, operator's platforms, and most importantly, a drivetrain to the rear wheels.

2:16 This is not a traction engine. it is a portable engine used for powering machinery using a belt off of the flywheel. it does not have the driving gear to move itself. they have a drawbar hitch on the front that is hitched to a traction engine to move it. And as for the steam being trapped inside the boiler, every steam powered machine has to have a safety mechanism on it. on a boiler is a safety valve witch will open at the maximum safe working pressure releasing excess steam so it does not put the boiler under strain and risk it having an explosion.

The principle on which the steam engine operates is so simple a child of seven or eight years can grasp it readily. The details of making it work reliably, with a tolerable maintenance burden and with slightly better than dismal efficiency filled the careers of mechanical engineers for a century.

Well explained. Without wanting to sound negative these types of engines were only a few percent efficient. Most of the energy was lost as heat and only a part of the potential energy in the steam was converted into work. Having said that-- These must be the most exciting and inspiring engines ever devised.

@@jonka1 even centuries later steam engines r still our most powerful source of power we have for mechanical energy purposes. Steam locomotives r around 6 times the power of any of its strongest competitors. And a steam traction engine of over 100yo is as or more powerful than our current best 4 wheel drive diesel tractors of the same size. Using the technology we’ve discovered and invented in the past century we cud modernize the steam engine to a point where we wud be using hardwood chip fuelled steam engines instead of gas, diesel, oil, propane or anything else fuelled engines. It wud simply be able to easily outperform everything else we got even more than it already does.

This is fascinating. The principles are probably somewhat similar to how our cars operate today, only using combustion instead of steam. Its all very interesting.
@8MADJACK
@8MADJACK 3 місяці тому
Steam is external combustion, the steam is continuous and shuttled through valves to push on either side of the piston. A gas or diesel engine is INTERNAL combustion, the fuel ignites and pushes on only the one side of the piston. The valves are timed to let fuel/air mixture in and exhaust out, so different ways to accomplish the motion of the flywheel
@hedgehog3180
@hedgehog3180 Місяць тому
Both steam engines and modern internal combustion engines are heat engines so they are fundamentally similar. The only engines we regularly use that aren't heat engines are electric engines, and that's why they're so dramatically more efficient than all forms of heat engines. This is also why sustainable power sources like wind, solar and hydro are so efficient, they are not heat engines so have an intrinsic advantage when compared to fossil fuels and nuclear power.

The superheater is a pretty neat invention for locomotives(steam locomotives to me are just one great compilation of inventions really, engineered w/ 0 computers, nothing else quite compares), creates even higher pressure steam then what would be used coming straight out of the boiler. And something thats also pretty neat is, trying to picture the steam inside a locomotive being so hot, its entirely invisible until it hits atmosphere. Which is something interesting to compare to the normal "steam" you would think coming from tea pots etc..

A lot of the inventions of the steam engine start to seem a lot less complex when you learn about thermodynamics. Like they're definitely impressive but thermodynamics is just such a powerful tool for examining machines of all kinds that it quickly guides you in the direction of the best designs. Like ideas like the steam turbine follow quite naturally from a thermodynamic examination of the steam piston.

I like this video ... for the most part. I particularly like the molecular level explanation of how steam exerts force. But it suffers from a common problem regarding what measuring system is being used. I'm assuming that when the narrator talks about force being in Kilograms he is not using a gravitational metric system - assuming that such a thing even exists. He likely meant to say Newtons of force. In what used to be the standard metric system - the Meter Kilogram Second system, a Kilogram is a unit of mass - not force. The unit of force in that system is the Newton. It is sorta the same as saying pound in the Foot Pound Seconds system where force is in Pounds and mass is in Poundals. Here endeth the lesson. Thanks for a very good video.
@alexanderSydneyOz
@alexanderSydneyOz 2 роки тому
Seriously, considering the level at which this is pitched, pointing out that kg is not - technically - a measure of force, is excessively pedantic. Yes, it may be that from the point of view of a physicist, 9.8 Newtons and 1kg are not the same, but for all practical purposes, including YT videos explaining how steam engines work, it is. Likewise when it is pressing on your foot, it is too. Do you, personally, go around telling people they don't actually 'weigh' 80kg, because, as you know, weight and mass aren't technically the same, and the scales measure force not mass??

Amazing video. to the point and informative. My only issue (not a big one, just pointing it out for future reference) the Hudson 4-6-4. On top of the boiler the steam dome, sand dome, exhaust stack, and headlamp don't seem prototypical for a Hudson. The setup looks like it came from a 4-4-0 american. Especially the exhaust stack. The stack is specifically a wood fired loco stack. And the headlamp reminds me of an old kerosene headlamp. To my knowledge most modern locos had a standard headlight. Like it does on the center of the faceplate. No dynamo. And the cowcatcher looks to again be from an old 19th century locomotive. Again. Love the video. If I didn't mention what i did, it would of drove me nuts. Please take this as constructive criticism and not deconstructive.

Great and very well explained two parter...I learned something today thanks!. Just wondering, could the double acting type be described as a 'One-Stroke' engine? like in the way you get two and four-stroke internal combustion engines.
@kylesteele9403
@kylesteele9403 2 роки тому
Intriguing to describe -- even at its minimum it's considered a two stroke engine, four stroke when steam is inputted during up and downstroke

Branch Education My favorite things about what I like about the steam locomotives are (1) Most of them just only have one tender behind the cab, (2) Most of them have leading wheels, driving wheels, and trailing wheels; (3) Most of them are fueled by coal and water, (4) I like to watch the engineer blowing a whistle to the let people know that they're coming, and (5) I like to watch the fireman shovel coal into the boiler with fire inside which makes a lot of steam coming out of the smoke stack straight out of the cylinders (with pistons on the inside) connecting to the rods.

This is a very nice, very well build, explained and visualised video. Great work! It is unfortunate, that it ends with claims without arguments. I highly encourage You to make a separate video on the present and future of ingeneering, instead of cramming it at the end of other videos. It is kind of an antiklimax to the very pleasant factographic tone of the rest of the video :)

Also steam engines are not tiyed to fossil fuels like internal combustion engines as just about anything that burns can be used to make steam. My 7.5 inch gauge locomotive "Axolotl" burns wood. Because of this most engines in the US burned wood until almost 1900.

@@johnkuzma7066 yes, and maybe more things. electrosmog is another one. Electromagnetic pollution is measured in µT, it is demonstrated that a machine should not emit more than 0.1 µTs to the passengers. Planes and actual trains are planed to be replaced by submarine trains that have the same motor than actual trains, then, they will emit 100 µTs or more. This means that passengers' ADN "may" be changed in a very bad way, developing symptoms and pathologies as: serious harms in the immune, neurological and neurovegetative systems (in the worst cases, people develop tumors or leukemia, the effects on the body are cumulative, and the risk may be worse in children, pregnant women, the elderly and the sick), electro-sensitivity, electromagnetic fields with frequencies between 100 kHz and 10 GHz can induce the absorption of radiated energy and cause an increase in body temperature (the lower their frequency, the deeper the penetration of these fields in the tissues), neurological disorders (nauseas, migraines, etc.), heart and lung disorders, reproductive problems (infertility, pregnancy problems, abortions, etc.), disorders due to impaired hormone production, skin disorders, among others. In the case of non-submarine energy trains, people living in the vicinity of railroad tracks may be exposed to magnetic fields generated by the electrical supply source located above the tracks that can be similar to the fields produced by, for example, high-voltage power lines.

Great video! One question was left unanswered, that is how the valves did the timing sync with the piston, without using any electronics unlike now-a-days? And how did the accelerator work in steam engines?
@oregonrailfan7046
@oregonrailfan7046 4 роки тому
The accelerator on a steam engine is called the throttle it's attached to the boiler backhead in the cab a rod is attached to the throttle and it runs along the boiler and connects to the steam dome or in some locomotive's it runs inside the engine when the engineer pulls the throttle it causes steam to be released from the steam dome the farther the throttle is pulled the more steam is released
@anthonylester1349
@anthonylester1349 3 роки тому
In a steam engine locomotive It's called the Regulator, and it's also a complicated mix of Regulator and Reverser positioning and turning various little valves and opening steam and water jets...apart from making sure you have the right amount of fuel, water, temperature, pressure etc.

@paranoidgenius9164
@paranoidgenius9164 3 місяці тому
The very first concept for locomotive technology was to couple the steam engine to a cart thus inventing the axel drive train, "training" the cart to move under it's own steam, the "steam training cart" which was found to work effectively on rails. But due to the hazards of high pressure explosions the entire thing had to be made from iron. The idea came when they had to transport the engines by horse & cart for testing at the cotton mills to drive their looms. It was definitely steam engine technology that drove the industrial era. A steam engine road cart wasn't effective on land, steam locomotion had to run on tracks to be most effective. Steam road carts would be slower than a horse so it was impracticable for any real use.
