- How carburetor works ?
Carburetor is used to mix gasoline into the intake air flow with ideal volume, and proper timming.
But how does it work?
Carburetor works by utilizing pressure differences. When air flows, the air pressure is lower than the atmospheric pressure.
This is called the bernoulli principle.
This principle states that the faster the air flow, the lower the air pressure.
Due to this pressure drop, gasoline is able to be sucked into the air stream.
But to get faster air flow, we need to add venturi in the middle of the air hose.
Venturi is a section of air hose with a smaller diameter. Its function is to accelerate the air flow.
So according to Bernoulli's law, air pressure can be even smaller. It makes gasoline more easily sucked into the air stream.
So, the carburetor uses the Bernoulli principle to mix gasoline into the air stream towards the intake manifold.
But how does the carburetor control the engine rpm?
Please see the anatomy of this carburetor.
This is a variable venturi carburetor.
In this type, controlling rpm is done by adjusting the width of the venturi.
So before we go on, we should know some important parts of this carburetor.
First, the piston. It functions to regulate the width of the venturi.Main Jet. It is used to distribute fuel into the venturi.Idle air channel. It is an additional channel to flow the air at idle rpm.pilot jet. It functions to distribute fuel to the idle air channel.The last, there is a nedle jet. This is a pointed needle that adjusts the width of the main jet according to the piston position.
So when the engine is idle, the piston is in the lowest position. It makes the venturi very narrow. And the main jet is also covered by needle jet.
This condition forces air to flow through the idle air channel and fuel out through the pilot jet.
When we pull the rpm handle, the piston is lifted. This makes the venturi wider and main jet is open.
So that, greater air volume flow through the venturi and fuel also sucked through the main jet.
The higher the piston position, the wider venturi will be. The wider the venturi, the greater the air flow. So that the result, the faster engine RPM.
Then, we know that the fuel tank is higher than the carburetor. Why fuel doesn't overflow?
Apparently, there is a float system that makes the fuel does not overflow.
This system only utilizes float movement to close the fuel from the tank.
So when the fuel in the float chamber is empty, the float goes down and the float needle is open.
That makes gasoline fill the float chamber.
When the gasoline is full, the float rises and the needle also closes the fuel.
So there is no fuel flow to the float chamber. This makes the gasoline does not overflow.
When the gasoline in the float chamber decreases, the float drops and the gasoline returns to fill the float chamber.
And the last, you must be confused by the screws on the side of carburetor.
The screws are used to control the idle rpm.
First idle air screw. It is used to adjust the width of the idle air channel. So when it tighten, the idle air channel becomes narrower so that less air passes through.
Second piston screw. That will adjust the height of the piston when idle. If it is tightened, the piston is lifted and that makes more air flow via venturi.
Music ruined all efforts of explanations 😔
That's true
Totally
absolutely True...
Although the music was somewhat distracting, this is still the most helpful explanation of how a carburetor works that I've seen.
Yeah
The best Explanation but not necessary music.
Iíi
Copy right issue
This person that made this video has their head up their ahsol! 😂😄 the stupid music has nothing to do with how a carburator works.. IRRELAVENT in all it's glory!!!!
Spanish music? Why ??
why music ?
if you're gonna use music use one without vocals
And don’t play it louder than the damn announcer
Robot voice was bad enough, but then the music made me run screaming from the room. Remove the music, put a human on the narration.
😂😂😂😂😂😂😂😂😂😂😂😂😂 👍👍👍👍👍👍👍👍👍
The background music is annoying.
Remove the background music....
Are you out of your senses? Where's the point of distracting a viewer with that non-sense music playing in the background? Re-Upload a proper version.
Right like wtf
At least thank him for the effort. It helped me to fix my motorcycle
🤣🤣🤣🤣🤣
ur old fashioned nicola
LOL!!
If you can get past the robot voice and music, it's actually a really good explanation.
It's so good explanation both these nuisances don't matter after a minute!
I actually paused my video, I was trying to find out where the odd music was coming from...
I unfortunately could not get past it lmao
The music wrecks this tutorial
The music in background don't give you to study
This video was super helpful, thanks so much. I initially understood what each part is and what it does, but not how they work together and how they do what they do. This really tied it all together for me which was super awesome. my only complaint is obviously the music, makes absolutely no sense to put it there in the first place lol
I have to agree with some of the other comments, the music was awful & really distracting.
Carburettor explained in a simple and concise way. Thanks. 👍
Excellent! Exactly you said what was always bugging my mind about those screws.
EXCELLENT explained of air flow in carburetor thanks it was more informative ever and nice 3D used.
Very good explanation and animation. But the music is distracting and annoying!
The video is so knowledgeable and the background music is so irritating why do you need the background music 😠 i shut the video off because of it.
Best carburettor explaination bro. Keep up good work.
Absolutely the best explanation of the principles of how a carburetor works. Good on ya, Mate
Great graphics and great explanation. I was going to share this with some of my students but with the music it makes it hard to understand. Quite annoying actually.
This video solves my questions.Thanks
Don't add background music to this type of technical animation videos . Just a voice over will do the job .
Wow ,that was magical, especially the srew parts
Well done .may GOD bless you.
Screaming music totally unnecessary
Keep upload on this kind of video additional knowledge
Very helpful thanks for sharing 👍 and subscribed
This video was very helpful - this makes me think something is wrong with the float, have to open it again.
Great explanation 11/10
Very nice and clear explanation
this much volume of music makes distraction in ur video
beautiful video
Very good explanation sir 👍
It was a much more clear... explanation of carburetor. Great work thanks
best video of my life
explained very greatly thank u
very good explanation thanks Dear Sir
Pretty good explanation
Music is not needed nor necessary here. Very informative & one should watch and learn before adjusting the carburetor.
Good explanation.
I wanted to know the separate functions of the two screws in carburettor.
Only reason I clicked it to be honest 🤣
Superb explanation
Great explanation
Very useful, thanks
' Precise n clear explanation .. very useful! Just remove background music .. 😊 Thanks!
Good explanation sir...
I wanna dance 1hr into my exams..bravo
Good effort for explanation of the concept. However the music was not needed. Thanks for uploading such an informative video.
Terrific video
Fantastic info, easy explained. Just that back ground music is shocking, too loud
The question is does the oil from the jet pilot mix with the main jet while the trotle is full?
Nice explained , no need background music 🎶
Thank you. I have been needing this video all the time. The music was unnecessary tho. Like from here
A music video explaining how a carburetor works. Brilliant.
Thanks for you lesson sir
me gustó el video gracias 😉
THANK YOU!
Good explanation
good work
Best explained
Muy buen vídeo explicando como funciona el carburador de un motor. Lo que no entiendo es porque poner una música por encima del educador mientras explican el funcionamiento. Si posteas este vídeo nuevamente SIN LA MÚSICA te daré un ‘Like’ y me subscribo.
That music addition and selection is so random haha
you didn't call the music bad. you're disgusting.
:p
Lovely explain ❤️❤️❤️❤️🙏🙏
Why do you need both the air screw and piston screw?
This explanation is so good, it even made me listening to that shity music
Useful ❤️
My bike RPM doesn't go rapidly done when accelerator is pull down. Can you tell me what is the problem
Awesome👏✊👍
Please upload it again without the music. It's very good!
The music destroys everything 😟
Love u brooo❤
Thank you sir very much. I research currect and best knowledge about carburetor principles, You tell great information. So i subscribe your channel. But really music interrupt concentration.
Great video, but background music totally disturbing
Please make another video how to work fuel injector?😊
Very useful vdo.. concept is clear now.. but background music was distracting 😀
The music was probably to prevent copyright
no copyright if you cut the music every 2seconds. i do that for how many times. no copyright appeard in my videos. if you cut the music do not put some spaces so that the music flows clear and clean
great teaching
You dint tell the function of idle channel and jet while main jet working and piston is higher... And how pilot jet plays important role in bike's milage....pls tell asap. M curious to know it.
Thank you
Thanks for best explaination .but music is distracting
In fluid mechanics there is sudden contract and sudden enlargement there is a losses of head how to mature the fuel air ratios please
Excellent video, lose the music or lower the volume.
New sub⭐⭐⭐
Because of loud music the words were not audible
No music or cut the volume please..
good video 👍
Is carburettor capable of making your plus wat with petrol?
It doesn't show the air fuel mixture screw works and how it's connected to which channels
Thank youuu
😅very helpful 🤖
The music is a BIG diversion.
Everyone talking about the music but I just watch it without volume and seen what I need to see but I get some people are hands on learners and some are not I wonder if it's the same with haveing to hear on explaining. Interesting
I get the idle screw to adjust the idle rpm but What is the point of the piston screw other then it to tighten to make it go higher ??
if adjusting the idle doesnt help?
I have this same question. My guess is that the idle air channel / pilot jet are just not designed to do all of the work of keeping a bike alive at idle
Nice
that is great animation and explanation but music sound is too much for this
Thansks for this video, is very helpfull and 3d graphics are quite appropriate but music really sucks
Very informative 👍, next time don't add the music in the background.
great video explanation minus the pesky music...lets add another tiny venturi to route water droplets into the engine as the throttle opens and you probably get 20percent fuel economy as a result....(men in black enters the chat...)
naaa just spray some water on the intake, but only if the engine is at or above working temperature to avoid hydrolock
very good explanation with a beautiful animation but background is very disturbing
I watched and learn with the video in mute mode and it is effective .
Let me try that
Will you please upload the video again without the music….Thank you.
What will if the spring inside is cut?
