А разве , кто то может , это Невидеть ?? Надо разгонять дальше .И вообще поставить магниты или катушки , пусть эл.Ток вырабатывает , нефиг даром туда - сюда . Учённые уже создали ,давно всяко программу - зависимости диаметра , длинну хода и прочих размеров ?? Секретна , поди . Думаем , этот тип уже изжил себя , пора бы и новое что нибудь .@.
The fact that humans managed to make metal move this fast consistently for hundreds of thousands of miles and not have it break even slightly is incredible level of genius design.
Нас занимал , другой момент , ЧТО может нарушить этот процесс ?? Ему без раздницы , эта скорость , просто через трубу не может бежать больше газов и горючего , чем сечение трубы , настанет предел .
@@Steve1766in a 4 stroke engine the piston goes up and down 2 times for every revolution of the crank, so whatever your crank rpm is dowluble it to get the piston rpm
Understanding the thermodynamic cycle in each stroke and realizing that cycle happens hundreds or thousands of times per second is truly mind-blowing. A true engineering marvel.
@@notnem3883that is still hella fast for chunks of metal. By the way rpm is measured by the crankshaft, not the pistons. At 7k rpm the crank shaft spins at 7krpm. Pistons don’t move nearly as fast
There is extra weight on the crankshaft to balance the weight of the pistons. If the rpm gets too high it's possible to " float" a valve. The dohc is an effort to reduce the weight of components in the valve train, to allow higher rpm and increase h.p..
Some people asked how fast real engines run. Most gasoline car engines run about 2500 RPM to 3000 RPM at highway speeds... so that would be about 50 turns per second. (ie 25 power strokes on each piston per second) If you have a 6cyl engine, that would be 150 power strokes+sparks for whole engine per second. Another way to look at it: if caris driving 60 mph (88 feet per second) at 2500 RPM in a car with 4cyl engine, then the gas used for each piston's power stroke is moving car fwd about one foot. (or 1/3 meter) For metric perspective: if 3000RPM gets a car with 6cyl engine to 120 kph (33.3 mps) then each piston power stroke (150/sec) moves car 0.22 meters. (22.2cm or 8.75 inches) Most 4-stroke diesel engines in pickup or truck will turn about 2100 RPM at road speed... so that is 35 turns per second. If that is a V8 truck engine, you have 140 power strokes per second, and could be driving 60mph, then each cyl power stroke moves truck about 7.54 inches or 19.16 cm. Small gas engines like motorcycles tend to turn higher speeds, and may run 6000 RPM (twice as fast as car) near 120 kph... but could only have two pistons, which would be 100 power strokes per second, so a 4stroke 2cyl engine would move cycle about 33cm per power stroke. (aprox 1ft. which is similar ratio seen with car I listed first)
Impressive! So can you school us on how a locomotive diesel engines (both EMD two stroke 567/645/710 and GE four stroke 7FDL etc.) performance please?!👍🏿
Engines spin so amazingly fast. I like how the frame rate of the camera relative to the timing and speed of the two pistons creates a visible interference pattern.
Y eso q lo giran con motor eléctrico, imaginen con la explosión de la mezcla, verlo en tiempo real (claro q es imposible) solo imaginarlo me sorprende y hasta donde la mente humana ha logrado con tantos conocimientos de años lograr q exista esta maravilla del motor a combustión.
I’ve been wanting to see the pistons go at real time speed for YEARS. THANK YOU for doing this video. I now know how fast my Beetle’s pistons go. It’s amazing
In genere ci stupiamo delle performances dei piloti che si esibiscono su mezzi mossi da questi miracoli di meccanica,mentre ci dovremmo stupire dei miracoli degli ingegneri che progettano tali "opere d'arte"!!
Not exactly, the sound that you were hearing was from the probably eletric motor that was simulating how it all happens, a real car engine sound comes from the combustion on top of the piston, where an air and fuel mixture is injected, then the piston goes up, compressing this mixture, and then a spark plug emits a spark, combusting the mixture and creating a force which pushes the piston back down, and then the combusted mixture, now in form of gas, goes out of the combustion chamber (the place where all of this happens, on top of the piston) and into the exhaust system, and then the pistons repeat this cycle over and over again in a very, very fast way, and remember that this cycle is for a standard gasoline engine, diesel engines work in a different way
Brilliant animation! Now consider that a 6,000 RPM crankshaft speed is completely normal. Just imagine the speed at which those pistons are firing up and down with the crank spinning round 100 times per second 😳
