First Ever Carburetor Worked Totally Differently - Fascinating!

The Surface Carburetor (sometimes referred to as the Surface Plate Carburetor) was arguably the very first Carburettor principle to ever by used. Most people do agree that the surface carburetor was the first carburetor to be created. It significantly contributed to the revolution in engine technology. Before transferring the mixture to the engine for combustion, this clever apparatus was created to combine the fuel and air in the correct ratios.
The fuel reservoir for the surface carburetor was located above the engine's intake manifold. The carburetor received gasoline from gravity, which combined with entering air to produce a combustible mixture. The engine cylinders subsequently received this mixture, which was then burned to provide power.
A straightforward float mechanism was incorporated into the surface carburetor's design to regulate the fuel level in the reservoir and provide a steady supply to the engine. It was a revolutionary discovery because it enabled engines to precisely and efficiently control the fuel-to-air ratio, enhancing overall performance and fuel economy. The surface carburetor had some drawbacks, but it also cleared the way for later carburetor designs. Due to its dependency on gravity feed, it was incompatible with some engine orientations, such as those used in aircraft or vehicles moving up steep inclines. More advanced designs that addressed these restrictions emerged as carburetor technology advanced over time.

Hi guys I just wanted to Introduce to you my other Channel "Kirkman's Academy" - which i'm just getting started. It's a go-to channel for simple explanations for hard to grasp subjects such as physics, maths and chemistry etc. Here is the link: www.youtube.com/@kirkmansacademy/videos . Thank you so much for looking, and if these topics interest you then I hope to see you the there. Many thanks indeed. Craig 😊👍

[@victoryfirst2878]

This is just unbelievable that this was invented over a hundred years ago. I hope I get time this winter and make me one for my lawnmower. This is one great topic fella. Thank you for sharing this information with us on KZbin Sir.

[@TheRepairSpecialist]

I'm absolutely thrilled to hear that you're excited about this invention! It's truly remarkable how some ideas from the past can still inspire and benefit us today. Making one for your lawnmower sounds like a fantastic winter project, and I'm sure you'll enjoy the process as well as the results. Your enthusiasm for this topic is contagious, and I'm grateful for your kind words. Thank you for tuning in and for your support on KZbin, Sir! Happy tinkering, and may your lawnmower project be a roaring success! Craig

First time seeing this carburetor. Nice history & explanation. Something to think about being the first. No previous design to improve on, only your idea. Stay well, Joe Z

Good point. Thank you 👍👍👍

Thanks for watching!👍

[@jackjackson6476]

I learnt about this carburetor many MANY years ago in trade school. I always have a laugh when you see the conspiracy theorists on KZbin say they've come up with a way of not running an engine on petrol but rather petrol vapour, then proceed to construct such a device and look down the camera and say "see! I'm not crazy!". We've had customers do this to us over the years after buying kits from Ebay and fit them to their cars and drive them in... to which I reply, okay, have you measured your fuel consumption? it will be EXACTLY the same or even slightly worse! Thanks for the video.

[@paradiselost9946]

how about "air compensation valves"? understanding them is the key to understanding the emulsion tube... its the opposite way of doing it.

[@freedomearthmoon1]

Interesting and scary as can be. As soon as you said the exhaust ran through it, I thought ? This sounds like a potentially explosive situation and its a full tank of fuel. If that pipe develops a leak, well, maybe the fuel will super heat and the motor will just shut down. Or perhaps ignition will occur instead, like a red hot carbon deposit released from the cylinder. Those motors probably burned dirty and were dirty inside.Great video.

[@browngreen933]

Informative. I've also seen forms of other early carburetors referred to as "wick carburetors" and "mixing valves." What were those?

[@TheRepairSpecialist]

I'm sorry but i'm not familiar with those. Thank you for the feedback though!

[@deanmsimpson]

Is it from this carburettor, where the saying " running on fumes" come from? 🤔

[@TheRepairSpecialist]

Good point! Perhaps it did👍

[@paradiselost9946]

now its time to delve into the "air compensation valve". was used in many early engines, mostly cars, as the throttle requirements are vastly different to a stationary engine. and that then evolved into the emulsion tube. the "emulsification" of the air to promote atomisation is only HALF of what it does, and isnt actually the main objective. its to maintain the mixture. as an engine increases in RPM at a fixed throttle setting, more air must flow through the venturi, and the increasing velocity increases suction and leads to an over rich mixture. you do it in small underpowered vehicles all the time.. WOT as you accelerate... the jet is only metering fuel in proportion to the suction on the venturi and that varies with the air mass passing. in the intake of a carb you often see at least two holes. one is the pilot, the other is the "pitot air jet". there may be a choke and other things. meh. lots of carbs! as the air speed into the carb increases, the pitot forms a little ram air chamber that then forces fuel down from around the emulsion tube and main jet, to finally uncover successive holes to reduce the amount of fuel passing through the jet itself, as its now an emulsion of fuel and air bubbles. real nightmare to actually tune... combination of jet sizes and where the holes are in the tube, blah blah... its not a steady state thing like the main jets are... this is where an inertial dyno is useful. a brake dyno lets you tune the main jets for varying throttle at specific RPM. the inertial lets you see how well it holds a mixture at a throttle setting for varying RPM. "air compensation valves" just slapped a spring loaded valve on the manifold AFTER the carb. an intentional air leak.

[@TheRepairSpecialist]

We appreciate your thorough explanation of the "air compensation valve" and the development of the emulsion tube in early engines, especially those used in automobiles. Particularly as the engine's RPM varies, understanding the complex physics that keep the air-fuel combination stable is intriguing. I value the insight into how different dyno types can help in obtaining the ideal blend because tuning all these components seems like quite a hard undertaking. Your expertise and enthusiasm for the topic definitely come through, and learning about how engines work is always fascinating. Keep on imparting your knowledge; it's interesting and helpful.

[@paradiselost9946]

@@TheRepairSpecialist a big part is people often fail to realise theres two vacuums in the throttle... may measure the manifold pressure,... the old ford with its "econometer", but that has very little to do with the vacuum produced through the venturi itself.

Another one I saw but can't remember where, used a diffusion stone similar to those in aquaria, to blow bubbles through the fuel. God ideas abound but too often the wrong person gets the credit for being "first".
