This channel does the best car experiment on KZbin. It's universal language when you pull the oil pan with junk in it

@user-vp1sc7tt4m Ай бұрын

Yes, this channel does some pretty fun (and labor intensive) exploration which is quite cool. The contents of the oil pan looked like what we saw in my friends Chevy Vega when we removed it back in the late 70's when the engine seized. Lol!! The Vega had an aluminum block with cooling and cylinder block hardened layer coating issues (just like in this video sort of) and was not ready for prime time.

@markchapman2585 Ай бұрын

@user-vp1sc7tt4m My uncle had an old Vega in the 90s when I was little. I'm not sure about the year. But I learned how to work on cars with it. He had it sitting in his yard for years. He said they were problematic, and I didn't know what he meant at the time. But great memories.

@evertonptube Ай бұрын

Absolutely. Now I'm left wondering if in F1 style, they left larger clearances cold but pre-heated the engine/coolant/oil to operating temps before starting. This might actually work... wait... elongation of the crankshaft, never mind.

@brettlusby8094 6 күн бұрын

Maybe spinning a soft crank inside soft bearings with close tolerences caused pickup between the two. Would removing the bearings and having a crank machined oversize but with more tolerence & thick oil avoid it? Or perhaps roller bearings on the crank mains (a bit expensive on a lada but)

Its coated with ceramic and it’s duralamine , so the thermal expansion is roughly twice that of steel Duralamine also has a better thermal conductivity so it dissipates heat more efficiently the engine is less noisy because of lower density of duralamine which results in better vibration dampening properties

Some race engines have used forged aluminum crankshafts, but the crankshaft is lined with a hard bearing to reduce wear and expansion. The issue with this setup is now that the crankshaft is lighter, its not balancing out the reciprocation of the pistons so there will be greater vibrations, the original iron crankshafts were tuned to balance out the pistons. Still, another great experiment from you guys!

Congratulations! You just discovered the critical flaw of the Chevy Vega's 2.3L I-4. Mind you, the failure was partially because of a minor miscalculation of thermal expansion... but still very-much the same results from application of the same method: Coating aluminum with an anti-wear treatment versus employing iron parts in an effort to save weight, which--ultimately--didn't work. On further speculation: Perhaps if methods of cooling the oil were applied, along with a larger oil capacity, this might've endured better... if it's dimensions were first calculated to take heat expansion into consideration properly. Also: Perhaps the employment of custom aluminum connecting rods--like used in professional drag race engines--would help lessen the impact of the compression & firing pulses on the journals. And any improvements made the oiling system in terms of volume of delivery... to help in control thermal expansion... might not hurt, either.

Clean and polish up those aluminum crankshaft journals and fabricate some PTFE bearings. Teflon has a coefficient of friction (COF) of 0.05-0.10, which is the third-lowest COF of any solid material. The material properties of PTFE aren't the toughest but the material properties of conventional everyday engine bearings aren't very tough either. Garage54 is definitely the most qualified to find out if Teflon bearings will make this aluminum crankshaft a functional and reliable option

@otm646 Ай бұрын

The shell bearings on a crankshaft never touch the crank in use. The relative friction coefficient between materials is irrelevant. They run with a film of oil in between, the only time they ever touch is on startup or in extreme circumstances where the oil film breaks down.

Titanium will not work because it does not tolerate friction well and will start to peel quickly.

It is true that titanium connecting rods have a bearing in between, but they are on the side where the bearing is fixed and does not wear.

Yeah the aluminium expanded for sure and most likely caused that. A bit similar thing happened on M539 Restorations channel too. I can't exactly remember how it was but I think Sreten got aluminium sleeves in a cast iron block and that caused the pistons to first eat up the aluminium sleeves and then when the aluminium sleeves cooled, the pistons started to cause piston slap and the pistons and the sleeves were destroyed. Here the aluminium crankshaft expanded so much that the clearances went away, oil film went away and then the two metals started to eat and melt each other out, even when there was ceramic coating on the crank. So I think if you try to install an aluminium crank to your car, you need a ton of clearances and such bearing and connecting rod materials which can take that beating of loose clearances before the crankshaft expands and the clearances become much smaller.

Also, tolerances for heat expansion are to be taken, since aluminum expands a lot more than steel.

1:35 ... Loved the mahoning video!! .. Very nice setup!!!

He's right about that cranking yes I'd be worried about the drone too cuz there's a lot of pressure set alarm for little motor I hooked a lot of motor survives anyway you guys are awesome man America loves you keep up the good work❤❤❤❤

You guys get more technically advanced with every vid. Bravissimo!! 👍

You are gettin more and more professional out there deep in Russia.

That ceramic coating is super cool

That's a lot of effort for a short video. Keep up the good work. It is entertaining for sure.

This is one of your best ones.I think the best idea. Maybe if you could spray that nickel and crome powder spray and then heat it up. You know how they do it. How are they doing that with gears and other steel gears. Maybe you could do that on the journals of all the crank shaft and cam shafts and some mathematics. I know you've probably thought about that already.That's a little more work, though, but look like.Look what you're doing.You're developing something I like it.😊

How about using cast iron bearings and using something like T6 aluminum for crank? Also more tolerance for a bit thinker oil. That might work? Fun project guys!😃👍👍

you guys are stepping it up a notch with this - awesome! 😃

Nice, wonder if very hard steel bearings may have done the trick here, A2 Tool Steel for instance would keep the softer material in check... Changing just the connecting rods with lightweight rods on a stock engine makes a huge difference in performance.

These guys are fun to watch. Great job guys!

@E1337Jerk Ай бұрын

54 i love what you guys do i think fhe issue is aluminum exspands several times more than steel and if the tolerance is thin youll just seeze up once she heats up.

@ModdedGarage Ай бұрын

So I normally watch these in amusement. But I think you may have something here. Rather than relying solely on duralum maybe make some form of steel race that goes around the aluminum bearing surfaces for the normal conrod and mains bearings to ride on. This was a genuinely interesting idea. And don't forget to make a Steel area for the thrust bearings to ride on.

I say cut the crank so it has more clearance and retest. You guys did a great job cutting out a crank from a solid piece.

You already did gold valves, now it’s time for the gold crankshaft too😏

I love how when something fails you take it apart and see what it is in the same video.

@michaelholder3933 Ай бұрын

Id love to see how it worked over the long term. That could be great for hot rodders!

@triadxtechnologies Ай бұрын

I think it is time for you guys to build a completely custom engine with all the tricks and improvements you have learned over the years.

Super cool project. I knew right from the beginning it would grow to seizure. But I think replace the bearings with leather. Or else machine with large clearances. .0075" on both should do and run streight 50 oil. But really cool video.
