[@jayemeljay2117]

Thank you Destin!! Venturi sounds a lot like Bernoulli... Was that the original name and it got lost in translation???

[@kingcosworth2643]

To help smash up the fuel carbies have air bleeds running to each circuit. This carb has a single main circuit but pretty well all carbs have at least 2, an idle circuit and a main circuit. Running to each of the 'tubes' of each circuit is another tube with a tiny hole mounted at the air horn (intake side). This starts to airate the fuel before it gets to the venturi where it is vaporised further. It stops that droplet effect seen in this video, which increases response, economy and lowers emissions.

"Can you run TWO cylinders off of one carburetor? .....SERIOUSLY??? Clearly, this guy IS NO MECHANICAL ENGINEER. Don't tell him it can run EIGHT cylinder and more.....oh he did tell him .....too late. This video is great for explaining to kids, how a carbureted engine works .....but leaving out all the nonesense from this clown. "I understand carburetors now. Yeah. I mean, I guess nobody actually a hundred percent understand it" ...... TOO INSULTING. DO NOT USE TERMS LIKE "STOICHIOMETRIC" WHEN YOU ARE SO VERY CLUELESS ABOUT EVERYTHING AS SIMPLY AND FUNDAMENTAL AS A CARBURETED SYSTEM.

I am a 63 year old third generation Electrician, second generation Refrigeration Engineer, first gen Controls Engineer. Midway through my refrigeration career I took an advanced OEM course which featured a see through refrigeration system made with glass tubing in place of all the coils and tubing, and the instructor showed normal operation and a multitude of faults which were now so easy to understand. My understanding of these systems sky rocketed after this class. Best money I ever spent, and it made me the go-to-guy for several Manufacturer Service centers in a large area. One picture is worth a thousand words worked miracles for me and I hope this is not a lost art. Kudos to you you guys for carrying on this type of learning, it is fantastic and can't be beat.

@@agerrgerra1361 It's a single cylinder, so it has a primary and secondary imbalance. The first order is mostly cancelled out by the crank counterweight but the second order happens at the top AND bottom of the stroke and it's from the piston changing linear velocity while the crank's rotational velocity doesn't.

[@zemari5180]

I love this video cause as an intern and a student studying computer engineering, you need to always remember that no matter how much you study the people who really know engineering are the guys who work on it. Whenever I can I love to talk to tecnichians, electricians, and mechanics because while we study design, their lives are working on it. Just cause you go to school and have a fancy degree doesn’t mean that you can’t be taught something by someone who doesn’t.

[@wrxpilot]

Well said. One of the most valuable parts of my mechanical engineering education was spending a couple of years learning how to fabricate parts in a machine shop. I did this through FSAE, and even got to learn some basic TIG welding. It absolutely changed my perspective on design and manufacturing. It’s painfully obvious when an engineer has never spent any time doing that kind of work!

[@bradgiles935]

Man I'm a gearhead and have beeb working on engines and carburetors for decades. I had the same working understanding of how they work just like your dad, but to actually see it all in slow motion is some of the coolest stuff I've ever seen. Kuddos to y'all for doing this!

I probably watch this video on a bimonthly basis. It came out when I first started really tearing my motorcycle apart, and it's such a tremendous example of how exactly carburetors work. Now I'm helping my dad out, taking apart his motorcycle with him and tuning it up. Thank you for a wonderful video!

[@dakotasims2688]

So, I just want to mention something that I think you may find interesting if you look into it, but you notice how as the intake stroke neared completion, there was a flow inversion that caused the fuel to push backwards out of the intake just slightly. That is caused by the intake valve closing, and sending a sonic pulse through the intake runner and back up into the carburetor. On four barrel carburetors, that pulse signal is actually used to time fuel delivery from one cylinder to the next, and good camshaft design takes advantage of that inversion to open the intake valve of a different cylinder at the exact moment that the inversion happens. This allows a faster and more efficient fuel air charge to be literally rammed into a different cylinder running purely off of physics, and not having to rely on the engine's vacuum to begin the flow of air into a cylinder. Food for thought.

[@LifeisGood762]

Incredible, thanks for this comment. That's really cool.

[@tarangill3125]

Woah, I did notice that and was wondering if that was the valve closing in late and some pressure coming back! really nice to know what that really was
