From time to time we bring you viral videos related to cars, but I can assure you that today is one of the most interesting we’ve seen and published in current engine. And is that, as you’ll see in des button play, this video will leave you hypnotized if you’re a lover of mechanics. Just look on YouTube “engine performance 4-stroke” to see how it works internally an engine, but they are unrealistic videos because they are made to computer.
In this case, the creators of the video made a methacrylate cylinder head can withstand for a limited time the performance of a small 4-stroke engine. If to this we add a camera capable of recording quality at super slow speed the result is, as you’ll see, shocking. Many know to fund the operation of a four-stroke combustion engine, but we have never seen it this way. It also has subtitles in Castilian.
In these minutes, the boys of Warped Perfection, are operated to this small engine with gasoline, alcohol and acetylene. The most interesting of these sequences is see how to develop this 4-stroke engine working cycles, with the respective movements of the valves, as well as the spark jump causing the flame in the cylinder. To appreciate it with clarity and enjoy of these fabulous images is playing the video 150 times more slowly that in time real.
This has allowed us to see how the intake valve opens, the piston moves toward its bottom dead center sucking (admission) fuel air mixture. The valve is closes, the piston rises until its point dead top (compression) and appears a spark that turns on the mix leaving us some images precious. Immediately the piston back down in his third time of work (expansion). The exhaust valve opens while the piston returns to raise from its bottom dead center to its top dead Centre (exhaust). Then returns to start this loop.
