纸做的世界最小发动机

    A software engine has constructed the smallest engine in the world and it’s made entirely out of paper.

    The tiny single-cylinder* engine, complete with a throttle*, runs on air from an attached balloon.

    This contraption* is about the size of a thumbnail and has a piston stroke of 3 millimeters.

    Aliaskei Zholner is the creator of this miniature piece of machinery and has a collection of paper engines that he’s built over the past six years.

    His latest creation is just 18mm long, 13mm wide and 22mm wide, with a shaft diameter of 0.5mm, making it the smallest contraption yet.

    Single-cylinder engines are often seen on motorcycles, motor scooters, mopeds, dirt bikes, go-karts and is used in many portable tools, they are also constructed with metals like steel, cast iron, and aluminum*.

    But Zholner’s design won’t be used for anything other than a showpiece.

    The software developer was able to capture the true essence of a single-cylinder engine and recreate all of a normal engine’s granular* mechanisms out of paper.

    The miniature engine is designed with a small crank on the side to power it manually, but Zholner hooks it up to a balloon and uses a throttle to control the air flow. And it even makes a slight revving* sound while operating.(SD-Agencies)
