100 H.P. Fairbanks Diesel at Oblong

[MultiSuperSonic1000]

whats that other engine at 0:13?

[pileofiron]

@MultiSuperSonic1000 That is another Fairbanks Z. I don't know the exact model?? It is running a big pump to circulate water to cool the big engine.

[JaxxBat]

Nuttin like big ole American iron..

[bigmekanik]

horsepower is a derived calculation.... U take a measurement of torque, and feed it into a formula with the RPM at which it was measured and that is your horsepower rating... 550 lb-ft/sec = 1hp..... so if u got something that makes 55000 ft-lbs/sec @ 100 rpm, thats 100 horsepower.... if u got something that makes 55000 ft-lb/sec @ 10000 rpm thats still 100 horsepower. But which one do you think would make more b-hp? 100rpm, let it twist all day, run for decades... ^_-

[bassaddict1231]

i could listen to that sound all day

[djdzaster]

its a real ferarri XD

[GermanCarTestsFL]

what is these FLOP FLOP FLOP FLOP FLOP FLOP every second ?

[pileofiron]

@GermanCarTestsFL I think you are actually hearing the exhaust..

[gus23a]

@GermanCarTestsFL

just watch this vid: 4000 cu. inch 1 cyl. 4 cycle engine Superior

[X4nd3Rde]

@GermanCarTestsFL das ist wenn die flamme leicht im auspuff zündet... einfaches expiriment: küchenrollenrohr mit einem feuerzeug mit gas befüllen und dann anzünden... *floop*

[GermanCarTestsFL]

what is a SEMI diesel ?

what is the diference between a fairbanks an a otto engine?

[pileofiron]

@GermanCarTestsFL Manufacture

[BronzeGiant]

Elnora, IN has a 3 cyl Page Dragline engine that I wish someone would post a video of.

[spark23ca]

i wonder how much fuel that would use to run a 80 or so kw generator by the hour or day

[fixitdude74]

Aren't "semi-diesels" two-stroke??

[pileofiron]

@fixitdude74 Yes, this engine ports the exhaust at the bottom of the stroke. Uses a burner to heat the pot on top to help combustion on start up and then they is turned off.

great thanks for sharing

[Bidone1967]

Nice engine - sounds good!

[Flyboy207]

OK, this is going to sound really stupid because I work with older engines but, ist it really neccesary to have a HUGE flywheel? I know that you start aircraft engines with props on them, but is it a momentum thing or what? Because I saw what looked to be a belt pulley on the other side.

[pileofiron]

I don't know all the answer but because these are slow speed engines they use the weight of the flywheels to store energy. Even though they are slow speed they have alot of torque...

[howtowakeakar]

My guess is that the flywheel helps smooth out the interaction between the motor and whatever it is connected to.

[hiyadroogs]

Flyboy, on these older engines, power was developed at very low rpm compared to modern engines. Bhp is the product of torque & revs, so the only way to obtain the power required was to have a large capacity engine that would develop enough torque at those low revs to give the hp. To carry such a large capacity engine over the compression stroke, required an enormous rotating mass. Without such a large flywheel, the engine would kick back & stop before top dead centre.

[Flyboy207]

AH! I get it now. I guess without that flywheel it would be hell to crank. Broken thumbs for everyone!

[Polybun]

@Flyboy207 It is needed to dampen the harmonics generated by the large displacement of the engine. Without that large fly wheel the engine would run very rough and damage itself and anything you tried to power with it.

[Flyboy207]

@Polybun Ok. that makes sense.

[pumpkinheadedsob]

@Flyboy207 The large flywheel is to keep momentum when loads are applied to prevent stalling. in a low rpm engine with a long stroke you need to keep momentum to allow the govener to react before the engine stalls, higher rpm motors can loose more rpm without danger of stall, but most of these engines run at speeds of less than 1000 rpm hence the need for a heavy flywheel.

[demonxanthwataru]

@Flyboy207

A large part of the reason older engines have large flywheels is because the larger wheel smoothed it out. They didn't have balancing down nor have nearly as much information as far as what goes on in the combustion chamber as they do now. So they put a large flywheel on to cancel out a bunch of the nuances, a side effect is that it made the engine harder to kill, and many used the wheel to attach drive belts for machinery to.

[zozey1231]

What do they mean by "semi-diesel"?

[pileofiron]

Very good question. This engine does not have enough compression to fire the diesel fuel when cold. There are 2 open flame burners at the top of the engine to preheat the heads. When the engine warms up the burners can be turned off.

[1700iDiGuy]

this is called a 'hot bulb' engine the hot bulb is a small chamber that the fuel is sprayed into and when the piston rises it squashes the compressed air into this bulb and the heat of the bulb + compression ignites the fuel and power commences, just like a normal engine, it works just like a 'indirect injected' diesel with a prechamber, though you use a blow torch to preheat the bulb before starting, now we use glow plugs. :-)

[Polybun]

Well no, these aren't really hot bulb engines. Hot bulb engines need the bulbs at all times and all loads. These are true diesels, and only need the preheaters for starting. This is no different than the glow plugs fitted to 99% of all modern diesel engines.

These engines make more than enough heat during the compression stroke to diesel. For example, you can take one on a warm day, crank it with a tractor till it goes, it will eventually just go with no preheat. takes about 5 minutes.

[civilmaddog420]

that sounds amazing

[grangeroo]

Where is the ECM?

[pileofiron]

I don't know if there is a Electric control module. This is for display only so maybe they don't have it hookd up or maybe they didn't get it. Thanks for your question. Fred

[Renatodonadio]

I think that engine was from around 1920's so it's all mechanically governed, no ECM at all :-D

[stingraystud]

@grangeroo just under the flux capacitor

[Taterslawify]

2100.8 pound feet of torque at 250 rpms...

alot of torque.

[macfletcherhotmail]

how could you get the engine to work hard because i bet you will need about 5 big generators gust to get it down 1 rpm

[pileofiron]

100 H.P. at 250 RPM's is a little over 2100 foot lbs. torque.

[586guest2]

haha! put that in a honda civic! 100hp! so little but so revolutionary for its day!

[anthacdc]

This Has a Lot more torque then a 100hp today.

Plus will last forever not like all these new chinese engine.

[586guest2]

mabey its because they actualy whent by HORSE power back then. thing about todays 1hp weed eater moter. would a 1hp weed eater moter be the same as an actual horse? if it is than why dont we have weed eaters pulling our wagons around? it would be fuel efishiont! i think someone screwed a decimal point up somewhere. so that is actualy equivilent to 100 horses! sweet!

[anthacdc]

your right!

[rudolphna54]

No no, you got it wrong. A 1HP weed whacker could technically do the same amount of work as a horse could. But slightly different. (these numbers are not even close to the real ones, they are just an example to demonstrate the idea) A weed whacker could move 10lb 1000feet in one minute, say. A horse could move 500lb 100 feet in one minute, but both could be considered 1HP because they are expending (or burning) the same amount of energy to accomplish the task.

[amfan12]

A horse can peak at 15HP. Horse power is the same as it is now, as it was back then. Call it horsepower is not that acurate as you can see

[slurp812]

@anthacdc small 600cc motorcycle engine makes more power...

[anthacdc]

@slurp812 haha you dumb ass, obviously dont know these old engines, this thing would have so much more torque than a 600cc motorbike engine, and pluss 100hp in the old days, accually meant 100 "horse power" it was accually equvlant to 100 horses, now you get crappyy weed eater engines that are some how 2 horse power? were is the sense in that, a 30cc engine is alot less stronger than 2 horses. Mate do your research before commenting on things you dont know about.

[slurp812]

@anthacdc I know what HP means. Torque @ 150 rpm isn't very useful in 1/4 mile times. Torque is great for tractors. Not very useful in a modern car, or a motorcycle. Plus it weight as much as a house.

[anthacdc]

@slurp812 fair enough, but these engines were not made for cars, they were made to work hard on farms and factorys, were they were stationary and did not move much

[slurp812]

@anthacdc Its very cool to still be able to run this. Fun to listen to the lumpity lump...

[slurp812]

@anthacdc Yup, you could get a smaller engine to do the work, but it wouldn't last that long. That is all day long last for centuries 100 HP...

[9020powrmax]

One great engine in its day. By the way, Im impressed with the sound of the exhaust........

[TECHKLEC]

An OSHA inspector would have a field day of his own there!

[injunscout]

Those big diesels are incredible engines. Nobody buids anything that durable these days!

[1944johndeerel]

nice video
