its crazy to see how far the diesel engine advanced the first 60 years of development, but it is even crazier how much it has advanced just in the last 15 years.
Advanced in terms of fuel efficiency, bu not in terms of ruggedness. Some of these engines still run today. And you can run almost any fuel/oil in them.
Yep. Fucking brodozers (toeing trailers and going off-road never) doing 4WD launches eating up their soft rubber mud tires, overstressing their transfer cases and half shafts, cooking their piston rings so it’ll be burning oil and coking up the turbo so it will seize... all so they can say they won against a stock four door family sedan.
Very true dat! In fact, you can say that pretty much about any technology in the past 200 years.... Electricity, Computers, Solid State devices, Music/TV/Movie equipment, Planes, Rockets, and so on....
Add a turbo and the efficiency goes up even more. I wonder when they were doing the arctic tests if they noted the engine had more power with the colder more dense air.
You really got to take a moment and appreciate how so many people back in the day were so freaking smart to figure this stuff out. It always amazes me.
16:58 Is showing the DM884WS-150 - the largest Diesel in the World up until the mid 70's - It was commisioned in 1934 as a stationary auxiliary power plant - at the famous HC Orsteds Works in Copenhagen.
Even though the world is transitioning to electric, I still think diesel is the best way to compress energy for use in work machines because for one, the most efficient batteries we have contain less electric potential and are flammable too. Fat-rich plants can be converted into oil, then biodiesel. The purpose of fuel is not to obtain energy, but to contain it. Doing so in a carbon negative or neutral way is a good bonus too.
I drive a diesel with 165bhp and 350nm of The chatty stuff. 0-60 in 7.9 and fantastic mid range pull. Great great engine. Great video, bad sound compress though.
Not sound compression. It is the quality of vids back then. When I was in elementary school, nearly everything had that hiss and pop in the background.
I had a diesel engine in 1947 bought it when i was 68years old..this year 2023 ive bought EURO6 truck diesel engine and works perfectly..cant imagine how diesel has evolved..want to get another one in 2075
As a diesel mechanic I have to say rudolph diesel is rolling in his grave seeing how the world has taken his creation of a great engine that needed no electricity to run to what it is now.......mechanical for me, thanks
I think he would be proud of the large ship engines. especially that one that creates 100,000 horsepower. However the ones in range rover and Mercedes are needlessly complicated.
First the sound track is a monophonic recording and it should have been on both tracks. Second, many of the prints had variable density soundtracks. If the track was printed too light it would create a lot of background noise. I have several prints and there is only one good one, done right.
diesel's original design was to run coal dust for fuel, but metering it properly was impossible at that time, so he switched to a liquid and that was originally peanut oil, but ended up being petroleum based instead. much the same way Henry Ford intended for his cars to run on ethanol because of availability and what was popular at the time.
@wi11y1960 re: " Gasoline was sold in hardware stores as laundry detergent." AND - it didn't contain lead or other additives as gasoline has since WW2 ...
FYI: Nicolaus Otto of Eugen Langen's Deutz AG was not the first to build the 4 Stroke engine. Christain Reithman of Austria obtained patents for his 4 Clock Cycle engines in 1873; 3 years before Otto and Langen. Reithman sued Deutz AG for patent infringment. Otto negotiated a settlement plus a pension for life for Christian Reithman and for the right to be called the first to have invented the 4 Stroke Engine; Reithman agreed. None of us in the later years would have known of this accept Eugen Langen's son, Arnold Langen, wrote a book about Nicolaus Otto and his 4 Stroke Engine with one of the chapters documenting the law suit. Arnold Langen made arrangements for his book to be published after his death. Arnold passed away in 1949. The book was titled, "Nicolaus August Otto - creator of the internal combustion engine".
Man, oh, man! Whadda delicious way this here to acquire culture... Not the average corrosive "kulture" but the real thing. Hats off to you, Whoever you are, USAI...
ManInTheBigHat Did you know, that Detroit Diesel and their likes poisend american school kids for decades with way dirtier exhaust gases? www.ucsusa.org/resources/clean-school-bus-pollution-report-card
It's comforting to watch this without the annoying "timer" and channel branding from other channels. Thank you. (BTW.. They originally downloaded the videos they show from you in the first place!)
I'd say because of its age not despite. These days it'd be so dumbed down that you wouldn't learn anything - and the first 10 minutes would be all about safety!
I really enjoy historic things like this ,especially on machines like engines. I can see the Diesel is good. A freind had a VW rabbit Diesel and it got up to 60 mpg wich a gasoline car of same sice got about 40 mpg
My comment here is only based on historical and factual truth,, and has no intention to be an entertainment ,, but if you see it as such is because you don't comprehend its real meaning, thank you.
@280aden The British Film Institute in London (situated on the South Bank) They look after a wide variety of films, some very rare social history ones, including material going back to the early days of film.
actually no. The air is delivered seperately from the fuel. The fuel is delivered at a later time because if they both were delivered at the same time the compression ratio of the engine would not be able to exceed the level of compression where the air is heated to the optimal flash point, when the fuel would ignite. by seperately injecting fuel, the compression ratio can exceed the ratio where the air reaches ignition temperatures, therefore making diesels more efficient and more powerful.
icantellfakefromreal No. It is just air. He wasn't talking about the diesel engine, he was referring to the fire piston which gave Rudolph the idea. The fire piston uses only air and it ignites by compression only.
Air itself will ignite a substance. I purchased a fire piston because I thought the concept so interesting. Fuel like diesel or gas is not necessary to make combustion - only air and pressure.
@@tjlovesrachel judging by the image quality, probably from early 40s. Or perhaps it was filmed at that time and released in MCMLII. I am just guessing, am not familiar with machines and their history.
They never mentioned that Rudolph Diesel was almost killed by one of his early research engines which exploded. What else was left out of this “history” lesson?
Ok, one stupid question. When we go to the example of a single gear rotating in two directions; how can a single or couple of gears love faster than the other. I can't see that part in my head. Please help!
A smaller gear rotating fast turning a larger gear will get a slow turning large gear with higher torque... A fast moving large gear driving a smaller gear will get you multiplied rpm's, but a great loss of torque... In a transmission you can see the different gear ratios... Low gear is slow speed but high torque... High gear is high speed but low torque... That's why you have to shift to get to speed... if you start in 5th gear, your engine will most likely stall...
Very cool vid and very informative, but we now know the internal combustion engine at its best today at perhaps 30% is still very inefficient and can't compete with electric motors at 95% or more.
