- How do carburetors work? This video explains carburetors and the components involved. They are used to mix the fuel into the air entering the engine, and are placed just before the throttle body.
The technology is old, however is still used in small engine applications such as lawnmowers, weedwackers, chainsaws, etc.

self-taught college kid who makes a professor's hour long lecture just as informative inside 3:30 minutes for most people to understand not needing the entire physics behind the concept. great job sir!
erin morales Haha thanks!
You are damn right mate, why don't we have such lecturers in college, I mean, great minds like this guy, do exist after all.
Couldn't agree more :)
There are so many useless college professors these days. So many engineering students had to taught themselves.
Well you do have to understand the physics to truly understand what makes it work, otherwise you don't really know why it works, just that it does by being a certain way.
The choke is used to restrict air-flow at the start in order to inject more fuel for starting the engine. After that, the choke is left open and the throttle valve controls the airflow.
You're welcome! Glad it helped you out.
Cheers.
This is honestly the best explanation I've found. TY
Happy to hear it, thanks for watching!
True
I second that. Great explanation
Sincerely, Thank you.
Zero flash here but the info is just right
Wow, Jason I cannot believe how far you've come in 5 years!
+Nicholas Meehan Haha, thanks Nicholas! 4 1/2 but who's counting! ;)
+Nicholas Meehan I was thinking the exact same thing!! Completely different, in a great way!
@@EngineeringExplained Jason, I can not believe how far you've come in 10 years! :D Props to you man.
He a rocket surgeon now??? :P
Literally looked up a dozen of these videos and couldn't really grasp it till watching this. Thank you sir.
After having seen so many of your newer videos, it was so amusing to see this nearly 10 year old video from you! I do miss the short and sweet video format of days past...
It's amazing how tens of thousands of people paid through the nose for what I learned here in five minutes. Thanks dude. You explain this better than some machanics I know
He explains better than any mechanic I had met. btw I only know like 3
cute
Miguel Dejesus You think you just got the knowledge of an engineering degree in a few minute video? Lol, keep dreaming. Ignorance is a bliss I guess.
Aeroscience atleast we will get an idea what it is and then study from book .why so ignorant??
I hope you never ever touch a car engine. You're a hazard going by your attitude.
Thank you! I still make mistakes but I try to at least make a note in the description if so. Glad you enjoy the videos!
Thanks, great to hear! I even use it myself from time to time; it's tough remembering everything. :)
Crazy to see this video after seeing a bunch of your newer videos! You've come a long way, but always done a great job!
It's a toilet for fuel.
You just summed up this whole video.
You heard of Rons flying toliet

12 years later this video just helped me understand my holley carb infinitely better. Thanks dude.
I've been watching CZcams videos for probably 7 years, and I am subscribed to a total of 3 channels. Including yours. Way to get to the point quickly and explain what you said you were gonna explain clearly.
5 stars man.
@Veggies94 Depends on the setup, can be either or, but one carb is more common leading to the intake manifold. Higher performance engines (older, obviously) may use one per cylinder.
The best explanation of how a carburetor works out there on the Internet. CZcams should put this video at the top of its recommendations instead of that horrible SmarterEveryDay slow motion camera dude.
This is the first video I watched. I'm going to subscribe now..
I'm trying to learn more about my truck. Your explaination and diagram are the most comprehensive way I learn. Thanks, I'll be checking out the other videos.
+LynchMobbin Thanks for subscribing!
Jason, if you were a professor in the vehicle department of our university, I would choose vehicles instead of electronics. Too bad that besides that's not the case, we are also of the same age. I admire your effort and your achievements. Keep up the good work mate!
Just what I needed. A concise, clear explanation. Thank you! And Happy New Year!
In a carbureted car it may not be much different either way, maybe less in neutral since it will be revving lower, then again in gear it doesn't need any fuel to continue moving. Regardless, it's a very minimal gain. If you're looking to save fuel there are much better methods. Drive slower, accelerate slower, etc...
Very welcome, glad you appreciate it!
One of his early videos still making me smarter! 😅
Interesting, thanks for sharing!
I remember checking out your videos about how all wheel drive, four wheel drive, and transfer cases work. Sadly I forgot about your videos but no more! I'm subscribing and definitely going to catch up on your videos. Great presentation and information, you are a very smart guy.
Bro.. You did what most animations and 3d drawings couldn't.. Awesome.
Explained very clearly. Thanks.
Yes, I should be getting into hybrids/electrics within the coming months!
Seeing your current vid on PI and DI, I went to look up the pros and cons of Carburetors and of course, this video is among the listed videos!
Dang! This video is pretty old and STILL has the easiest explanation to these systems. thanks jason. Been following for several years didnt expect to find this. Great job!
Seems like you could do it, I'd do some searches on forum/CZcams to see if someone's done it and see what all is involved. Good luck!
Awesome video man! really well explained. Im just about to start my motor-mechanic apprenticeship and your videos are a great way to help me understand how things work :)
keep up the good work!
so 3and a half minutes, that is how long a you tube should be, and this was great. Thank you.
I'm sure it could be fine tuned to optimal fuel efficiency, carbs were used in NASCAR I believe up until just recently, I'm sure they had them dialed in right. That said, it's very difficult to compete with direct injection, as this allows for the fuel to be injected at the exact times when it will yield the most power or the best fuel economy, something carbs cannot regulate.
Amazing video! I'm trying to convert a carburetted gas generator to run on propane, and I didn't want to proceed until I understood how the mechanism worked (since I'm otherwise exclusively a diesel/cooking oil person). This fills in all the scientific gaps, so thank you!
@powprashant Sounds right to me! Bikes with fuel injection are typically much easier to start in cold weather.
thanks for this vid. I'm a nerdy engineer who works on small engines as a hobby. This video was direct and to the point which was easy to understand. It's easy to present the information but to explain it in a way that makes sense is difficult. Your explanation was perfect. keep em coming.
Yes, it's possible. you would have the carb placed after the device creating boost (turbo).
Mate, this was a brilliant, easy to understand, and logical presentation of a carb. Kudos.
one of the best persons on internet explaining about car tech.. hats off mann!! :)
Thanks, I enjoy your passion haha
Hey, I'm from Germany and I'm working on cars everday. Since I'm interested in every technical detail I just want to know how everything works...now I just saw your videos and i got to say you explain everything just right - I didn't find any false statements! Keep on doing that stuff, your channel is awesome!
Thanks bro for all of your videos! They are really interesting, informative. well delivered and more importantly concise and to the point.
Thank you. I am an engineer, albeit in a different stream, and I appreciate the in-depth technical explanations :)
your really good at explaining stuff man. anytime I have a question about something, ill look up your videos
Thank you for this, I had little idea of what goes on in a carburetor and now it almost makes perfect sense.
Great video and explanation. Clear and concise, terminology explained, good usage of principles and easy to see visual drawing. Nicely done
As always, incredibly informative and comprehensible video. You do a fantastic job! Thank you!!
Glad to hear!
The best video on carburetor operation I have ever seen. Bravo.
CAN'T.STOP.LEARNING. !!! Your videos are adictive ! Congrats man and keep up the great job !!
Yes, more air means more fuel can burn. It's balanced. However, with a diesel vehicle the gas pedal actually does increase the amount of fuel injected (the ratio of air to fuel goes down).
Thanks, appreciate it!
I've said it once, I'll say it again - this guy embodies everything that's great about CZcams.
Unrivaled knowledge coupled with a natural talent for teaching... add to this the seldom-seen ability to include only what we really need to know, and what we have is an absolutely indispensable learning resource. The fact that, through CZcams, we get all that for free necessitates the burning question: why are we paying $$$$s each year for inferior quality tuition from our colleges? Huge respect to EE!
Wow I'm watching this video at 1000000+ subs. Congratulations
+ls7orBust same here
I love your videos but maybe it's time to revisit this and upload a more "updated" version. Please 😃
Nah never forget where his roots came from. Leave this gem up
This must be one from when you first started. You've come a long way that's really cool to see.
Very well explained. Thanks!
I never could understand carbs until now, you explain it very well and I have NO QUESTIONS!😎👌
The air intake, could be a filter or piping above it.
This couldn’t be improved on, a perfect explanation. Thanks
Thank you!
Thanks for watching!
The explain of pressure difference causing fuel to move is spot on. Most people think that the fuel is being sucked out of the bowl when in fact it is the difference of pressure that causes the fuel to be drawn out into the annular booster sitting in the middle of the venturi to be atomized.
Excellent. Didn't know a thing about Carburetors expect that they are used in motorcycles and cars. Now I feel I can design one haha. Precise and Concise explanation. Thanks!
Thank you for this. I am learning the basics and this really helps.
Hi, chemical engineer here, this is an EXCELLENT explanation.
Hey great work man! really like your videos, I want to ask a question, would it not be possible to replace the float with a fuel sensor which would sense the fuel level and then when the reservoir is full, send a signal to a device would would close the fuel intake and when the fuel drops, send another signal to the device to open up the fuel intake?
I was watching your current videos, until i bumped on this 1, do look like a teenage kid though, you were kicking since you've started man. Keep up.
Agreed!
I'm taking fluids right now and this makes so much sense! thank you!
Not sure what you're asking. It's so that you can have a difference in pressure, allowing for the fuel to be drawn to the lower pressure area.
very well explained, can be understood by anyone who have a zero knowledge on this kind of system, keep it up, and waiting for more videos..
This is wonderful. Never stop learning!!!
You are welcome! Thanks!
Very helpful thank you. I was trying to figure out my choke on my 1933 Dodge and this helped to set it. much appreciated.
WOW. I never knew that you were making videos that long ago. Congrats. I love your videos.
Explained the concept like a pro! Subbed!
Thanks! The explanation of the choke was especially useful.
Hi Jason. Thanks for the great video but it would be greatly appreciated if you could do a updated video including more info on carburetor. (Air fuel ratio correction, jet, etc.)
Ghoshan Jaganathamani why dont u just give him your sem syllabus
You just saved my life. THANK YOU!!!
thanks so much for taking the time to explain these things so i can understand. great guy hope you go far
Got a push mower that is giving me some headache. Guy I got it from said that if it wouldn't keep running it was a problem with the carburetor and he'd come by and fix it. I had no idea what they did just that cars didn't have them typically anymore. This video is fantastic ... thanks!
Thanks to COVID 19 I found time to understand how a carburator works and definitely, of the 7 or 8 videos I have looked at this is definitely the best. Congrats !!! i am suscribed to your channel right away.
I went to UTI in Phoenix (Avondale) I didn’t understand what a Venturi effect was, or pressure differentials / vacuum. I do now after working in the oil field. Good video
Thank you for such a clear explanation. Keep up the good work.
Engineering Explained Thank you so much!! :)
you are a perfect mech tutor
No two words about it
thanks, the videos provides more useful information than many other websites. Looking forward to more videos.
😢And now you're all grown up! Trying to source some videos for my son to watch. Yours are just as effective now as they were back then. 👌
Brilliant, easy to understand explaination. Good job
Best explanation of all the pertinent details available. Thank you sir.
Nice explanation. No need to use 10 minutes to explain a simple concept like every other video. Subed
Very helpful! Easy and straightforward, thank you.
I'm a mecanical engineer, best explanation I've seen so far..
Great job..
Thank you. Excellent Video.. I needed a refresher from 50 years ago
@igordvr Thanks!
Thanks for explaining
Hey there! I enjoy your videos, it becomes easy to understand by watching your videos, I want to request you for explanation of Carter, su and solex carburetors.
Thank you!!
Beautifully explained!!
Excellent video!
