The idle images of the engine running with a transparent cylinder are fascinating
You don’t have to be an engineer to appreciate the inner workings of an internal combustion engine. Thanks to this video, you don’t even have to like cars, or anything with a gasoline engine to be absolutely mesmerized by what you see here. In fact, we would go so far as to say that this is legitimate cinematic art, and it comes to you thanks to a single cylinder engine from an old Honda ZR75. Of course, there is a little more than that.
In fact, there is a parcel more, starting with a custom acrylic cylindrical wall. TROdesigns on YouTube walks us through the process of building this very unique engine and that transparent cylinder is obviously the key. As you might expect, it’s not as sturdy as a standard Honda single-beam, so to take the strain off the cylinder, the cylinder is slightly higher to lower the compression ratio. The piston is also polished and the custom piston rings are made from the ground up to help this engine run longer.
And run it. The high speed camera images that spin this mechanism make it a mesmerizingly beautiful visual work of art. This is a four-stroke engine, and with the action slowed down, you can clearly see aspects of each step. The air-fuel mixture from the intake stroke fills the cylinder with a mist that includes visible fuel droplets. The compression stroke causes the piston to rise, the flow of oil around the rings changing orientation under pressure. The power stroke is most spectacular when the mixture ignites, but the exhaust stroke sees the gases sucked out with surprising force.
We’re treated to several different views of this crazy engine running, both in real time and at idle, and we could watch it for hours on end. It’s one thing to know how an engine works, but seeing such components in action gives a whole new appreciation for something most people take for granted.
Don’t be surprised if you find yourself watching this clip a few times, and you’ll definitely want to stick around until the end. With reduced lighting, power and exhaust strokes take on a whole new level of brilliance.
