      @Dave Sims It continues because even the exhaust stroke sucks some air from the combustion chamber creating a suction - so the split second later on the intake stroke, it pulls the air fuel mixture in. This is even more evident on a 2 stroke engine - where a tuned exhaust hits it's "TUNE" point and gets even more power because it synchronizes pulling of the air fuel (oil) mixture through the engine - it's also why they are more powerful but more pollution is made from not having a complete burn. It's why 2 stroke engines smoke. That's what a tuned exhaust is all a bout :) It doesn't really work with a 4 stroke because the back compression is a lot different.

      Why does the jet continue when the intake valve is closed and the compression stroke is beginning? Is it momentum? The way you explained at the beginning of the video, that the venturi causes lower static pressure and vacuum, I assumed the jet would only exist while air was flowing through the venturi, but from the video it seems opposite...that the jet exists when air isn't flowing, and the jet didn't seem to exist when air was flowing (unless maybe it was being vaporized to fast to see it coming out of the pin hole at all?). Great video all around, thanks for sharing :)

    I might have to direct my students to this video when teaching aircraft carburetors, though there's no choke/the mixture control works quite differently. However, it's a fantastic visualization of how carburetor icing can form!

  • Joe Shmoe
    Joe Shmoe

    Of course you know, it is NOT sucking air/fuel mixture into the cylinder...right? The whole concept of a vacuum gets confused in this way. That is why some people think space can't be a vacuum or it would 'suck' our atmosphere away. The piston draw creates a lower pressure environment, and atmospheric pressure tries to balance that out and pushes the air/fuel mixture into the cylinder. I know that you know, and I also know must of us use the same phrasing talking about it, but in a teaching environment is is important to be correct. - Cheers

    Hey Destin, I'm an engineering student in the Netherlands and would recommend you to do a video on the (due to climate change more often) struggle against water.

    Doesn't it seem like our fathers' generation had so much more practical knowledge than us, and our fathers' fathers even more so. When my grandfather decided he wanted a new shed, he didn't need plans or kits. He just bought some lumber and built it, and it was absolutely beautiful! It had glass windows, dutch doors, and even a loft. He was an electrician, I have no idea why he just knew how to do that. It would take me weeks of study and I'd probably have to learn (and buy) new tools. I would love a channel that is nothing but your dad explaining things and you building models to demonstrate it. I feel like I could learn so much. I know how carburetors work now!

    I agree, no one explains things better than dad. My dad comes from the same generation as your dad. That was when life was more simple: there was Less money, fewer choices & distractions & being resourceful meant the difference between the haves and have nots. More available time for true understanding driven by the need of being self reliant. Thanx for letting us share in your joy of learning and your great relationship with dad

    Thanks for this guys, I've been playing with carbs for many many years, and im still learning something new. It looks like (on this carb anyway), that the fuel that comes up out of the jet looking like a solid liquid, could actually be from the inertia of the previous intake stroke.

  • Rob K

    Love this, absolutely astounding. The jet itself has a very important part to play which is not covered in this video, but would be nice in a follow up at some point maybe? (please please please) which has it's own very sharply defined venturi effect and forces the fuel to atomise (think of the friend who sprays their drink out when they see something funny mid sip) so on the intake, the fuel doesn't dribble into the venturi, it vaporizes the fuel like what was seen when the engine stopped and the mist was seen. A worn jet causes too much fuel to enter the venturi, and not atomise correctly, so that the flame in the combustion chamber has to hunt and seek instead of sweep smoothly through the power stroke.

These are two firm British favourite comics, with very different acts (you have been warned).

    The higher speed of the air in the venturi causes low pressure, therefore the higher pressure of in the fuel bowl pushes the gas out of the tube (jet). Common sense would show it does not work. Like an airplane wing, the high speed air lowers the pressure. I hate to be a Debbie downer but, with computers available there is no need to continue this crude way of polluting the air. Electronic Fuel Injection (EFI) makes this into cave man, super pollution, technology, I am interested in all out war on the carburetor, using Open Source EFI in order to decrease air pollution across the globe, especially in 3rd Word countries. What I think would be interesting as a follow up, would be to compare the stats of EFI vs. Carburetor.

    I think that dancing column of fuel is due tot he inertia of the fuel column. The suction event accelerated fuel up to the venturi, but when the suction event stops, the fuel still has its inertia so it continues up into the venturi and would drop back down if not for a suction even coming along before it can. Also, your Dad is exactly right about the surface area increase, which is directly related to droplet size. As a newtonian fluid with surface tension, gasoline wants to stay a liquid and resists being atomized. This is why a cold engine needs such a richer mixture-- heat is a major contributor to vaporization. This is why cars have so much gasoline vapor in the exhaust when the engines are cold. It's also why cold engines get such bad MPG. Also, throttle position matters a lot because an engine with lots of manifold vacuum has the vacuum to contribute to vaporization. At full throttle, it's nearly ambient pressure in the manifold (less restriction) so the means of droplet breakup are almost entirely mechanical vs assisted by higher heat or lower pressure.

    I love this channel. I have learned some pretty interesting stuff. But I enjoy that rare video where you're learning about something I know. Watching your learning process. I grew up with carbs. On mowers, mini bikes, and cars. My dad and I would tear down our family car's Rochester QuadraJet to every last piece, clean it and put it all back together. He was an aircraft mechanic in the air force then a backyard mechanic the rest of his life. This video reminded me of doing that stuff with him. He passed a few years ago. But everything I learned from him lives on.
