Пластиковый поршень в двигателе

What this video is about

This video documents an experiment testing whether a 3D-printed plastic piston can function inside a combustion engine. After initial failures with standard polycarbonate, the creators successfully ran the engine using a carbon-fiber reinforced plastic piston with modified ring gaps. However, the engine lost power and stalled after only a few minutes of operation. An inspection revealed that while the material could handle the pressure, it ultimately melted due to the high temperatures of fuel combustion.
