How the internal combustion engine works from the inside (video)


On the YouTube channel TROdesigns published an unusual video, the author of which demonstrated how an internal combustion engine works from the inside. Especially for the demonstration, the blogger independently made a transparent cylinder, and also modernized other elements of the unit. Thanks to its high resolution 4K and Super Slo-Mo (very slow motion), you can see the movement of the flame in the combustion chamber in the video.

An American blogger has found an answer to the question of how to film the operation of an internal combustion engine without damaging the video camera. He independently made a transparent cylinder out of acrylic, which he installed instead of the standard element of a motorcycle four-stroke engine from a 1977 Honda XR75. In order not to scratch the cylinder walls, the enthusiast replaced the metal rings with polytetrafluoroethylene (Teflon) ones, and also modernized the original piston. In addition, the engineer had to reduce the compression ratio by lengthening the cylinder itself.

Riding with such an internal combustion engine will probably not work. However, the redesigned engine was the perfect demonstrator to see how the system worked. With slow motion and 4K resolution, you can see the intake, compression, ignition and exhaust strokes in great detail. In addition, the video demonstrates the movement of the flame in the combustion chamber, the breakthrough of gases through the rings, as well as the interaction of oil in the contact patch of the piston rings with the cylinder wall.

A similar experiment was conducted by Novosibirsk bloggers in mid-February. Experts decided to see what a working internal combustion engine looks like from the inside. For the demonstration, engineers made a transparent plexiglass pan and valve cover, then poured oil into a container and started the engine.
