One of the absolute coolest things I've seen in my 54 years. Gives you an idea of why they talk so much about "flow". Notice the way the fuel/air enters the combustion chamber and also where the flame-front is. Very, very intresting. Big thanks to whoever made this video.
To me, an IC engine will always be an amazing feat of engineering. For the valves, cams, pistons, to all function smoothly at such a rapid rate of speed is amazing! My bike revs to 15,500rpm . The idea that an engine can operate at such high piston speeds is amazing to me!
This is so clear. The video nails the way the 4-cycle engine works. I could not think of a better way to learn how a engine works. This should be shown to all high school boys in auto mechanics class. What is the history of this video? Where did it come from and what was it made for??
what people dont realize is that this happens multiple times per second in each cylinder. incredible footage. kudos to whoever got this footage! XboXd83 _ I second that statement!
been building engines off and on for 15 years. Always tried to imagine, whats going on inside the cylinder of a running engine. It's absolutely amazing to be able to actually seeee it. Sometimes I just love technology.
This happens thousands of time a day, within an arms reach of all us, and this is the first time i have ever seen it. it brings a whole new meaning to "suck, squeeze, bang, blow". WOW! i want a cam in my engine now.
I have ALWAYS wanted to see that. I always thought that perhaps someone someday might invent a material that would allow an engine to be made of some type of transparent materials so one could see this.
Yes it is the shock to the piston that cause it to have catsrpic failure but also the extra heat from running in a lean condition can melt them or cause detonation or both. Like you said hitting the kid in the back with a slege will kill him slowly pushing him with it but not swing it full force will move him but not snap his back lol.
Also for a 4 stroke engine the piston makes 2 strokes per revolution of the crankshaft. If the engine was running at say 15,000rpm then the piston is moving 500 times per second, and it can do that for hours on end day in day out for years if its maintained. It's amazing how high revving performance engines don't just tear themselves apart
Its proly for educational purposes so I think they mounted the camera on the edge of the cylinder head at a far side for best angle. I just wish to see it go all the way. Check out valve float. Quite interesting to see why double valve springs may not be enough for 8k rpms.
They do show the exhaust valve opening, its the one on the left! Also interesting to note that the inlet valve on the right is actually rotating when it should be full seated. Even under combustion pressure the valve continues to rotate. This would indicate poor valve adjustment or the very beginings of valve float. I wonder what rpm its doing? Cheers great vid!
Its amazing that such a primitive and unsophisticated air pump, as far as air pumps go, powers and moves millions of people around the world, and so little conceptual improvement has actually been done to replace it with something... effectively better. I think jet engines and turbines move air through a lot more effectively but apparently they are not nearly as efficient to be usable in motor vehicles.
