@Windhelm Guard You seem to be confused about how this works and are attached to one part that you know. The flat vs crossplane dosen't really affect the sound profile on this because there is still a piston discharging pressure at the same point in time that it would have previously. Honestly you should have taken more issue with the fact that it's a 2 stroke instead of a 4 stroke. Or the fact that just listening to the audio does, in-fact, sound pretty similar to an I-4 diesel....
Windhelm Guard

@Brundin Grabe it still wouldn't sound like any four cylinder diesel engine, because they're pretty much all flat plane.
Brundin Grabe
Brundin Grabe День тому
@Windhelm Guard That's advantageous when you have a counterweight, and are talking about a lot of mass over a distance. The mass is negligable to the power here, so it's more advantageous to go with 90 degree timing.
Windhelm Guard

@Tony which is weird because the 4 in the video is in a cross plane configuration, whereas modern diesel engines are almost universally flat plane. what this means is that the cylinders in the video are 90° out of phase, which is a terrible configuration because it generates a lot of imbalance. in a flat plane configuration they're 180° out of phase, which makes it so that the two middle cylinders and the two outer ones are always moving in opposite direction, thus cancelling each other out.

@GreatCentralGlory Some are, but everything that actually tries to produce high efficiency will inject steam on both sides of the cylinder, to avoid loosing energy from the cylinder cooling down.

This is something that should be implemented in ALL public grade schools. The way this could be taught to kids is nuts. I grew up on k'nex which I contribute my thought process and how I figure out things purely thanks to the things I learned working with k'nex. If more kids could learn through this would be huge. Teaches just how mechanically things work, which can be used towards sooooo many things in life.

@pyropulse well you have a good point but as you said yourself, as soon as the lengths or even the shape of individual exhaust manifolds differ you can hear a faint but noticeabal difference. this is the case for a lot of engines, different shape with transverse engines, different length for longitutanal ones. it's a huge difference furthermore if we have two cylinder banks (mainly observable with V8s) and two exhaust lines. when you equally fire left-right-left-right (1-5-2-6-3-7-4-8 or 1-6-3-5-4-7-2-8) it's quite harmonic but for most american models you go left-right-right-left-right so you have two cylinders firing right after another in one bank and in one exhaust-manifold and -pipe (e.g. 1-5-2-6-7-3-8-4). that's a big part of the gurgeling "american muscle burble" sound. also as pointed out before your firing order in essence comes down to the structure of the crankshaft which in turn brings different secondary imbalances which requires more or different additional "counter-shafts" and while the difference is slight and nothing you can put your finger (or ear) on it is noticeable.

​@JNaWK what? xD where the hell did you get that from? sorry, but that's the most ridiculous thing I've read this week. what happens in an internal combustion engine is an explosion very much so. the kicker is how fast your "plain old fire" happens (up to 4000 times a minute or 67 times PER SECOND) and more importantly that it happens with a huge increase in volume and/or pressure. if that doesn't satisfy the definition of an explosion than god knows what will. there are even see-through builds which pretty much makes the argument redundant.

if you are having literal explosions in your cylinders, you are having a bad day. in regular operation, its just plain old fires, many times over and over.

@Ty There's a good answer to that... You can have a radial engine air cooled, You can't air cool a V-12. Without the added extra complexity of coolant and radiators an air cooled engine tends to be more reliable in aviation applications.

Radial engines were used on airplanes for decades. Only got competed out on the high end by turbo props and on the low end by cheap mass produced car engines. So they can't be heavy for the power they give or planes would quickly change to better designs. Number of pistons space and center of gravity could be factors for why they were not populair in cars.

@Ty If you build in real life Round engine would use too much space and weight and eat up too much fuel while those supercar always try to reduce weight and can't use too much space for engine. and as far as I concern for now V and W engines are enough for those sport car on a normal traffic or even on race track. so other types of engine such as round engine would just hardly appear on some heavier duty vehicle such as Tank which need more power and don't care much about space,sound.

Remember that the Lord Jesus Christ died on a cross for you because He loves you so much. He then rose up from the dead three days later The Ten Commandments are called the moral law, (most of us are lying thieving blasphemous adulterer at heart and deserve hell) you and I broke the law, Jesus paid the fine. That’s what happened on that cross. By believing that Jesus died on the cross and rose up from the dead 3 days later and not just confessing your sin, but also repenting of all sin you have done and putting all your trust in Him in prayer, He will grant you everlasting life as a free Gift.

John Freeman

I'm sorry, I'm gonna have to argue with you on that one... STEAM power makes almost no sound when it's brought to just about the pinnacle of generation/application of power/recovery. If you look up Jay Leno's video on his Doble Model E steam car, you'll find that even HE refers to the power of the Model E as 'the Hand of God', because there is NO indication of where the power is coming from. The engine is almost completely silent, and when the inner wheel of the driver's wheel is turned (to allow greater steam power to be sent to the cylinders), the force of the acceleration is like the hand of god is pushing you back into your seat, because the engine makes NO additional sound to indicate it's pushing harder. This from a car that's running superheated steam in a recycling system, so there's no 'hiss' of released steam (since it's being run out through the condenser in the front - that looks like a radiator, but acts to cool the STEAM, not the engine, then returns the 'cooled' water to the boiler system) as the car runs. Truly an amazing vehicle, and the last of the great steam engines.

@RCP-1136 Most inefficiency lost in internal combustion engines is due to the friction generated by its own parts, not noise. Noise is the by product of friction being over come and fuel being detonated. If you put an engine in a vacuum(with oxygenated fuel) you won't hear any sound at all but friction will still have to overcome. And who told you electric motors were silent? I've worked on a LOT of electric motors and they are incredibly noisy things. Now compared to internal combustion engines yes, they are a lot quieter but they make a lot of noise because friction is and always will be a thing, and don't try to at me with, "It's the bearing and the drive shaft making the noise" argument, because that is still part of the motor. All moving objects have their efficiency reduced most by overcoming their own friction, which is why turbine engines are way more efficient than reciprocating engines, especially at higher altitudes where the air is thinner and the engine doesn't have to over come the friction of moving thicker higher pressure air and get even more efficient at higher altitudes.

Have you thought of a lubrication system so the compressed air carries a tiny amount of lubricant through the hoses to the cylinders ? That way you'd never have to worry about the wear. Look at systems for air tools like used in workshops, they'd probably work great.

An engine is just a fancy air pump. So recreating it with air pressure will make similar noises at similar times to the real thing. The tempo of sounds of these models are spot on to the real thing, especially the radial. Sounds exactly like one minus the roar.

Have you ever tried using multiple lines for the input air along with multiple “throttle switches” in sync? The line probably can’t supply the volume of air needed for the bigger engines to operate at peak torque. You can also see the psi gauge needle bouncing which indicates a drop in line pressure. Kind of like in pneumatic shop tools where you can see a difference in performance with different size air lines.

@Tiltorn What you're hearing (and the reason it's so similar to how the irl counterparts sound) is due to certain frequencies matching together. The actual constituent rattles of the lego doesn't have such a low pitch of course, but if you repeat that sound at the same frequency as a low pitch noise, it's gonna create that low pitch sound. This video shows something like that happening.

I read an article about a visit to an engine building shop that, in addition to a dyno, has an engine test stand that can just forcefully spin the engine without it actually running (using compression, just no fuel or spark). They also tested just valve trains this way (spinning, no compression). The author was struck by how much of the characteristic running sounds of each engine were still recognizable.

I think the engines might run more smoothly if you altered the air delivery; instead of having a single air line with a junction branching off for each cylinder, splitting the air evenly (one air tube leading to a t-junction that splits the airflow into 2, then each of those lines splitting into 2 lines, before feeding into each cylinder of the 4-cylinder engine, for example). Though of course that would involve more pipes.

@Lumen3 definitely. In the end this is what flywheels are made for. Would probably also help for the 12 cylinder radial to put another one behind it with half a rotation offset to minimize vibrations. And it would be super cool if you could pull the cylinders further apart and create a hollow axle in the middle kind of like on those fighter planes where they then put an autocannon in the middle. But those are probably just dreams in terms of Lego feasibility...

I like to think that Lego designers are watching your videos and using your ideas into their projects.

A little graphite would be a mess but would probably improve efficiency. These are very impressive

I love the 3 cylinder. Sounds exactly like a inline 6 idling, which sort of makes sense even though it has twice the impulses.

3:10 is this not speed up at all? If not, this speed is insane! Didn't expect that Air flow could be so good

Very impressive. My favourite was the 135deg V8, so smooth .

3:35 I love how it went from 'sad and struggling piston' to 'mid 20th century German belt-fed machinegun'. It really sounds terrifyingly like one, and i love every second of it. The engine is cool too i guess. ;)

would like to see how efficient the engines are, like how much air can it recompress, if it's even able to do so, or if there's a generator, can it produce enough power to pump some air back? would be interesting because of how the engine industry is atm

Now I'm wondering if it would be possible to build Theo Jansen's wind-powered Strandbeests out of LEGO elements.

Had a great idea the drive shaft add a gear that turn a pump that adds psi back to a secondary air source, making the car version more viable also having two or more psi tanks to use and fill the switch when one is empty might not make it a forever machine but pretty close

@Game Seeker This series of development started off in the stage developed by James Watt. What followed were quite similar engineering mistakes, plus their respective solutions (and failures). Each 'stroke' is a sinusoidal movement. Depending on the properties of the mounting frames, these movements translate into vibrations of which many transform into sounds.

Is this because piston strokes don't have a perfect circular motion? Or rather, perfectly constant movement during the stroke?

I like how so many of these engines sound like old Diesel truck engines which I love.

Amazing. I guess the only problem is that the compressed air still has to come from somewhere.
