What a hypnotic sound! One of the few engines that is genuinely relaxing to listen to. It does indeed speak, but perhaps Put-you-to-sleep, put-you-to-sleep!
And it's the combustion chamber itself that is heated. Also, the oily fuel ignites by the heat of the combustion chamber walls, and not by compression. Diesel had quite a bit of trouble to manufacture a compression chamber that had such a high pressure so it would ignite the fuel. In a way, these semi-diesels are the more crude version of a diesel, since they didn't need such a high compression. The hot bulb was glowing red.
This is a cold start, solid injection full diesel engine. It uses volume governing of the fuel. It is not a hit or miss gas engine and it is not a hot bulb engine. Hot bulb engines are low compression engines which require heating prior to starting, this is a high compression engine which requires no preheating. I have personaly run an identical engine to this one. Hot bulb engines could be four cycle or two cycle. This engine was more likely made around 1920.
The : hot bulb: is the same thing thats in VW golf or rabbit engine but now it's called a glow plug. A glow plug is only used for starting, back then it was on constantly and heated by a flame.
This is not a hit and miss guys. This is a hot bulb or semi diesel. It inject oil into a large precup chamber where it is vapourized but noes not ignite untill air is forced into the chamber. These engines are not cold starting like modern diesels since the fuel is injected as a liquid not mist and the compression ratio is low for true compression ignition. But they were very cheap to run ( would burn any fuel from gas to waste oil ). They could not rev much above 400 rpm.
A neighbor had one of those! If I recall correctly, it had no reverse. If you wanted to "put it in reverse" you had to change the rotation of the engine instead. And I'm not saying that all hot bulb engines need continuous heating during low load... just that it can happen (depending on the individual engine). I've seen it happen with my own eyes... But if it was due to a worn engine, too rich fuel mixture or something else, I don't know. I just noticed they had to keep the burner on.
there were diesel engines in 1910 but as far as I know all of them had a blast injection. This one is solid injection. So I agree it must be late 20's or early 30's as written in my old comment.
Actually, when they're running without load, for show, like this one, you sometimes need to heat the bulb more or less constantly because the low load doesn't keep the combustion chamber hot enough. But I'm sure you already knew this... :)
The bulb is the combustion chamber on top of the cylinder, where the fuel gets injected and then ignites not like in a diesel engine from compression, but from the heat of the bulb walls. In order to start such an engine, you first had to heat the bulb red glowing so it would ignite its fuel when injected. They are also called semi-diesels, since they burn similar fuels (but with more variety).
These old engines can be rhythmic and musical in their own way. This one is waltzing along in 6/8 time... I love the simplicity and raw power of these old power plants! Keep them alive for as long as we can!
Hot Bulbs had a chamber that oil or fuel went into and was heated before the engine could be started. Once started the heat was removed and combustion came from the heat inside the cylinder. Much like modern day Diesel Engines do but the compression is much lower on the hot bulb and I believe efficiency was lower because of that. I believe hot bulbs were the first engines to run on oil which later lead to Rudolf Diesel's engine that ran on oil as well but was much more efficient. =]
I don't think this engine was use to generate electricity, but to power a Threshing machine. So the famous Deutz trademark builded a lot of farming machine like this one. It was used before the Combine harvester came into use. There had exactly the same machine in my home town during the 60s, but only used for the Saint Jean festivities, in an act of remembrance of the old time. If you observe the background, in the video you'll see a lot of others farming machines.
It does not look like a hot bulb engine to me. I think this is a solid direct injection diesel engine. The injector can be seen at the top of the cylinder. The manufacturer is Deutz as you can see on the side of the engine frame. I don't think this engine is from 1910. It's more likely built late 20's or early 30's.
I wonder how the thermal efficiency of an engine like this, with a large cylinder turning slowly, compares to a modern, smaller, higher speed engine with the same horsepower rating. Which one will do more work on a given quantity of fuel? For stationary use, where the weight doesn't matter, it might turn out that the old, heavy engine is ultimately more economical!
I'm no expert but I'm sure this is a diesel engine. Deutz introduced their first non-compressed air assisted injection diesel in 1911, and had significant improvements in the area of direct injection in 1921. I can see an injector on the front of the engine, but there's no bulb for hot bulb heating that I can see. Also, generating engines nearly always have twin fly-wheels. I doubt this engine is 1910 but feel free to prove me wrong.
I know from "Lanz Bulldog" tractors, which are also based on a hot bulb engine, that they run on idle without needing to heat the bulb, until it's really cold outside.These machines are pretty neat...tok-tok-tok-tok-tok-tok-tok.... ;)
-ha a gépezet alapjárati hangját hasonlítod a zenéhez jól képzeled .A gépek is kissé túlozva de a tulajdonságukkal panaszkodnak-örülnek-dacosak stb. és nekünk kell rá jönni a turpiszságukra.
Wrong twice. First: It didn't need to be constantly heated by a flame, only when starting the engine. Second: In this so-called semi-diesel engine, the heat from the bulb ignites the fuels, while in a diesel engine the ignition is achieved through pure compression, so this engine runs on much lower compression (it was a huge task for ol'Rudolf to fabricate his high compression engine), while in a diesel the compression chamber stays much cooler (the heat isn't needed for ignition).
If you were near this engine while it it windy. Not only would you suffer 3degree burns(from the radiator)but no one would be able to shut it off the engine of death
@bluefire87HN Il posto è la fiera di Arsego nel padovano che si tiene ogni anno a fine ottobre (è stata fatta proprio domenica scorsa) Purtroppo l'ultima volta che è comparsa questa macchina è stato proprio l'anno in cui l'ho filmata (2 anni fa) e poi non ne ho più saputo nulla. L'anno scorso c'era ancora qualche trattore d'epoca a testa calda, alcuno anche in vendita. Quest'anno purtroppo nulla di nulla :(
the reson they are called hot bulb is because there is a bulb like metal thing o them that vaporises fuel this must be heated red hot before staring and is red hot whilst running
Yeah how nice to have a bedroom right next to its shed and have to constantly listen to that after a hard day's work. Give you 30 minutes til you'd be headed out there with a sledge hammer.
I think you got it man!! I believe they were oil engines like the first diesel engines were! Diesel Engines are the BOMB!! I run WVO in mine and save tons on fuel!! =]
youre joking right? i hope you are! the generator (not present) was linked up with the massive pully mounted on the flywheel. if the engines were that low output like you state we would have thrown it away and used horses still instead.
