Transparent engine v. 2 - will we be able to start it?

you know things are serious when Vlad FINALLY uses safety goggles.

All of this stuff really just makes you appreciate the amount of engineering needed to just create a working engine in the first place. It's just crazy to think the amount of things the engine needs to do at thousands of revolutions per minute for hours at a time and potentially for decades with severe temperature cycles and if anything goes even slightly wrong it's usually catastrophic. Like I can't even imagine how many times the camshaft needs to slap the valves open on like a 10 hour road trip

Holy crap! You got multiple runs out of it! The slow mo was A+! Glad this one held up with reinforcement.

The amount of work they put into this project just so we can watch how an engine runs on the inside for a couple of seconds before it cracks is amazing. Huge respect.

I love the fact that you guys actually used a slo-mo camera!

I would love to see the machinist's face the first time you brought him in the clear block and said "Yeah, could you deck this please?"

My suggestions will be: - retard the ignition a little bit - insert some kind of mesh or fibers in the resin, especialy in the most stressfull parts of the engine block Keep going, i am excited about this project ❤️

👏👏👏👏 that shot at 14:07 makes it all worth it. You guys should try a flat engine like a Subaru. So the stresses on the crankshaft don't push One direction. It pushes together rather than a p

Another option to avoid cracks/heat damage may be to use borosilicate glass as the cylinder liners - the rest of the block could literally just be a skeleton similar to your rebar frame you used this time. Use 2 stroke oil in the fuel.

It’s actually finally been done! This has been a YouTube saga years in the making. Seen many clear running single cylinder, clear carburettor, even clear jet engines but a running 4cyl is a first

I remember your beautiful transparent and illuminated valve cover. All the transparent parts of engines, transmissions, differentials, oil pans etc. make us understand the gas and liquid flow much better! Thank you very much! 😃👍👍

Week after week you guys produce amazing content, and the English narration is always brilliant too. The slow Mo footage from this is top notch.

I say dp it again, but mold in a crank girdle made of steel and a 5-10mm plate around the top to bolt the head to. If linked together vertically with rods, you could possibly have an engine that could run a little(very little) longer. Maybe even hold some boost! My backyard engineering brain was going nuts during the assembly portion thinking of all that could have been reinforced while maintaining the clear appearance. Great vid! Glad to have found you guys so long ago.

Instead of making the whole thing transparent with the crankshaft, Making only cylinders Transparent. add metal connection from the top deck (engine head) to bottom part (crankshaft ) making a tree piece part. That way the whole support will be on the metal connection between the head and crankshaft when combustion happens. This way only at TDC or combustion moment the glass will be loaded. Your current model is taking the whole load. from combustion to turning the crankshaft or rotating the crankshaft. It is the upward and downward pressure all together that's making the model cracking.

these guys crack me up, they find ways of entertaining us every single time. nice to see real people in a world gone to shit keeping smiles on faces

Unreal footage and the amount of work that went in to making just a few seconds of it happening. You guys rock!!!

Vlad, you might be the first ones to do this with success . Awesome, you could see the firing order and everything . This DEFINITELY was a 107% success . The block cracked right off, But I was sure that would happen . Good idea about using the tall deck to enlarge the combustion chambers . You guys are awesome . :)

This is actually an EXTREMELY good visualization of how much stress an engine goes under in just day-to-day operation. Never did I think THAT much force was being put into the crankshaft on a 4 cylinder engine. Sometimes doing the most out of the box things teaches us the most about the world.

You guys are awesome. Can't have everything go right all the time. Still a 107 % really good video

That slow motion footage is so good!
