Internal combustion engines can operate within a broad range of RPM, from as low as 300RPM in locomotives, 7000RPM in pushrod V8’s like the LS7, 9000RPM in the F20C found in the S2000, or as high as 20000RPM in the Kawasaki Ninja ZX2R and everywhere in between.

A quick addition to your point at 6:30 - the cycle limits are exponential - meaning that if you pick a force or a lifetime/ cycle limit, you can optimize and decide if steel or aluminum is a better choice. This is why drag cars use aluminum conrods. They're treated as consumable, and don't have to survive for long races.
@2bfrank657
@2bfrank657 10 ай бұрын
Perhaps that is true for aluminium, but steel has a sharp corner in the stress/cycle relationship as shown in the video. My understanding is that the fatigue limit is not actually perfectly flat as is typically claimed ("infinite cycles"), but that it simply has a very shallow gradient that is close enough to flat for most purposes.
@MrLuvtheUSA
@MrLuvtheUSA 10 ай бұрын
@@2bfrank657 I think maybe you are not understanding the graph correctly. The "sharp corner" for the steel rods is correct, as far as can be measured. Basically, if it stays below its fatigue point, it will last forever. As a diesel mechanic, I know that semi-truck engines are often rebuilt after a few hundred thousand miles, but that doesn't mean ALL of the pats are replaced. most of the time you would use new rod bearings and rod bolts, but the rods themselves would be reused. commercial diesel engines sometimes last over TWO MILLION miles with a few rebuilds.(that would have to be in the billions for cycles) Other parts(like the crank shaft) will also likely never be replaced

​@@2bfrank657 Unless my materials engineering professor and the books lied to me. Steel presents a stress threshold (for a given temperature) where, if not surpassed it won't suffer from fatigue related deformation. This is because the dislocations present in the crystalline structure are unable to be displaced around the matrix, resulting in no permanent deformation even at the microscopic level.

@@andresmartinezramos7513 Interesting. My understanding is based on what a tutor once told me, something related to "the German railways" and the very high number of stress cycles their axles underwent if I recall correctly. I've not seen this low-rate fatigue theory mentioned elsewhere though, and I expect your understanding of steel microstructures exceeds mine, so I think I'll research this a bit more before pushing this claim any further.

@@2bfrank657 Right now I'm travelling, so I can't give you the exact quotes (I'll try to remember when I get back). Any mistake is my own. But the idea was: In a number of steels the process of nucleation of the crack does not happen beneath the fatigue limit of the material. They insisted on us remembering that aluminum and composite materials do not present a fatigue limit and will always fail given enough cycles (which may be many). The reason for no nucleation was (If I recall correctly) that the dislocations got stuck by the interstitials and the grain borders. The energy to overcome this obstacles being too great for the amount of stress applied. This leads to the dislocations not combining and thus not growing. Sources online are just saying it happens, not why. The only explanation seems to be an answer in a forum by Jesper V. Carstensen in "ResearchGate net Why fatigue limit only exist in some materials?" So not the most reliable of sources. Again, I'll try to return to the topic in a few days.

One of the coolest way I’ve seen valve float be removed is how Ducati did it with their desmodromic valve where the cam opens and closes it. That’s how they can get such high revs. They also don’t use timing belts or chains it’s all done using gears, it’s a nightmare to work on but it’s amazing when it works.

You must be referring to the engine in current Ducati MotoGP bikes? The desmodue in my 2005 Monster S2R has timing belts and desmodromic valve actuation as do the desmoquattro and testastreta engines in their super bikes of that vintage. I’m not sure about their current V4 engines however.

Honda's 125cc, Five cylinder RC149, revved to 18,000 RPM with valve springs, made 30 hp and topped out at over 135 mph, in 1965.....it had 33mm bore and a 29.2 mm stroke, and four tiny valves per cylinder. Soichiro Honda hated 2 strokes, so in the 70s, when all the other manufacturers settled on 500cc four cylinder 2 strokes for their GPP bikes, Honda tried to beat them using a 4 stroke. The rules stated no more that 4 cylinders, so a 4 stroke would need revs, lots of revs to get the power needed to beat the 2 strokes. They built the NR500, it had oval bores, (like a spam tin) 8 valves and 2 conrods per cylinder, it was basically a V8 with siamesed bores (but still technically a four cylinder to stay in the rules) it would rev to 21,000rpm, and idled at 7000rpm!! It was a bit of a failure as a race bike, but the oval piston engine did get developed further into a 750 road bike, the NR750, (many styling cues off this bike were used on the Ducati 916) and the NR750 TTF1 race bike that look similar to the RC30.

It was used because valve spring material wasn’t very good. Ducati was already using that system in the 70’s, using bevel gear drive. 750ss Mercedes Benz used it in their race car engines in the 50’s. SLR It was developed for German fighter planes in WW2, but the design goes way back before valve spring material could cope.

Thank you for the video and the effort. Very interesting. If you really want to reach extremely high engine speeds, you have to use electric motors (100k-rpm possible). And people who miss the deafening noise of combustion engines can certainly add a sound generator.

Although the rotating mass is very important the friction is a huge challenge. My friend worked on these engines and no shell bearings were used in the rods, just coated surfaces.

This was a really cool video, I’ve been curious about the f1 and motogp drivetrains for a little bit and this was a wonderful introduction to the base differences of what sets them apart. One thing I noticed that I don’t believe was mentioned that I learned in a Rob Dham vid, from what I understand, the drivetrain tolerances are so tight that you need to preheat the motor prior to firing it up, and if it sits for more than 6 months(?) it will need to be disassembled and gone through. The throttlebody/inlet is fascinating as it is brilliant, on his cosworth (bought them for around 16k$ used) essentially there are 2 banks where a channel is made prior to the intake side on the cylinderhead that’s essentially a tube cutting across before the injectors/valves, in it a machined cylinder with 4 channels running into the head for the bank ported to allow air through, as the whole cylinder rotates to either cut off or flow or WOT. Genious for the simplicity and reliability.

Very nicely put I appreciate your videos , the exhaust one was very informative as well. To me it was more informative I never pictured the pulse waves the way you illustrated them. It answered a long partly unknown answer of why you exhaust is so important other then simply vapor removal!
