I'm so glad to see that after all these years Jason is still sticking with the whiteboard.
Yes. It's remarkable. =)
Very soon is 10 years
Yepee Jason loves whiteboards it's been 12 years now 🙌🥳 Thank you Jason
I have learning problems. I have a hard time paying attention in school. You explain everything and I understand it 100% something which my teachers could not help me with.
+Hakasauars Happy to hear it! Thanks for watching. :)
+Hakasauars it must be the well explained visual aspect.
00:00 a legend was born on utube
Is this his first video? Haha
Yes :D
❤ 10 years later
@nerdypielover Thank you! I'm just getting started with this channel so I'm hoping it builds interest. Throw suggestions at me for future videos anytime!
Over 8 years later, and 2.62 million subscribers later, one could say it definitely grew haha. Interesting where life takes us. 🤔
2021 checking in. You did fine.
in this video you were 48 years old?
10 years
Congrats on your success brotha. When I look for a engine related question I'm trying to answer, I always hope for a video from your channel.
You've come a looong way buddy.
Thank you for making my engineering life easier. :)
Love from India. ❤
You are welcome sir!! Made them just for people like you! Glad you enjoy them.
@yamenad Lighting has definitely been an issue, my camera doesn't seem to have enough lighting no matter how many I put in the room (it was cheap). Also, I wanted this to seem as if my friend has asked me how something works, and I'm simply responding in a manner that's easy to understand. What I say is what I know; it's not something I've memorized and rehearsed. Although it may seem more rugged, I believe it's easier to follow. Thanks for your support!
The beginning of a legend!!!
thank you. I just found your channel today but because I have recently became very interested & have devoted my self to becoming a true master mechanic/craftsman, so these videos are not only amazing (no matter the lighting) they are extremely helpful & informative.
So this is where the legend started... Great! Maybe you may not read my comment but I just want you to know something. By seeing your videos you have inspired me to study Mechanical Engineering and I really appreciate all the effort you have put into your content because I've learned a lot in just a few months that I've been following you. The world needs more people like you, going straight to the point, confident, humble enough to recognize when you're mistaken, and someone who likes to be in touch with his public. There's a lot of words that I'd like to tell you, but in a resume I'll just say a big: THANK YOU!
Greetings from Mexico!!!
Easily one of the top science and education channels on TH-cam. Been with this dude since the beginning and he's come a long, long way mainly because of how awesome of a guy he is. Don't get me wrong - the videos are very informative and very fun to watch, but IMO the primary reason for the channel's success is how humble, cool, and likeable the host is.
The first video of Jason whose taught me everything about cars,i love you so much man❤️❤️❤️
Much love from Kenya
Congratulation on completing 10 years 🔥🔥🔥
Right, I'm sure your car can handle it fine as it was designed to, I just didn't want people getting the wrong idea and thinking "Hey I'll put 20 psi in my once naturally aspirated engine and everything will be fine." Good to hear that your car is running strong!
Bro whats the difference between NA and turbo engine in terms of acceleration? I mean in an NA engi e u feel more and more power as u climb the rpms while in turbo u dont feel that
Check out the FAQ's on my website, the link is in the description (or it can be accessed on my channel page). I answer these questions in greater detail than I could in this little box.
This guy should do more videos. Seems good.
howdoesacarwork(dot)com. Nah, not there haha, but the FAQ's I answer in decent detail. You can also check the video description for the link.
I love that you have been doing this for 7+ years! Talk about consistency!
Started a job working in automotive retail, going to cram through your videos to gain some knowledge! Thanks in advance because I already know from watching many of your other videos that it will be immensely helpful.
@shunjingus Yes, the ratio attempts to stay the same. There are sensors measuring the amount of air going into the engine, which then tells the ECU to spray more fuel.
From this video to hanging out with Jay Leno. I can't believe it's been 10 years. Good job man.
So have I got this right? With more air you can burn more fuel. And with more fuel you get a greater explosion in the cylinder. And a greater explosion means more power to the piston, which drives the crankshaft.
9 years ago. Wow. Thank you Jason for starting this!!
I really appreciate these videos. They are at a perfect level for understanding the basics (and beyond) of engine/automobile engineering.
Thanks bud for the simple straight forward explanation
The last video I tried to view on this subject "How a turbo works" took this simple idea and made it 1000x more complicated by throwing in needless details.
Glad you enjoyed the video, thanks for watching!
Great job explaining bud. Bright future ahead of you
I already understand how most of the systems in cars work and why they are implemented, I just like these videos. Great quality, always accurate!
I literally just started to watch this guy and it’s his 1st video crazy
As long as the transmission can handle the input forces, yes, you can mix and match whatever you'd like. Size is relevant as well of course.
20 psi is quite high for a stock engine. Most of what I've looked at references 6-8 psi being the turning point where you'll want to swap out internals (for previously naturally aspirated engines).
"assuming you aren't in boost." is nearly the same as saying "assuming you don't use the turbo." The turbo is there to create boost. That's it's job. And when it does it's job, it increases fuel consumption.
dude, you're so comprehensive and straight forward. i love it.
Thanks!
I just realized the first video I ever saw from Jason was his very first video.
I distinctly remember watching this video and thinking this is the best way to explain turbos to my friends who didn't understand it back when I was in my first year of engineering school in 2012.
Haha your first vid
Got bored early in the morning so i tried to find your first video uploaded
Well, it would certainly increase power but could be dangerous. Hence it's used in N2O systems, the nitrogen helps stabilize the mix and keep things safe until the oxygen is needed.
@sage1wt Honestly I've been surprised with the amount of views I've gotten. Considering my channel is less than a year old, I'm pretty proud of 2000+ subscribers. But hey, if you want to spread the word, that'd be awesome! :)
I used to watch your videos during my undergard 4 years ago and here I am watching them again during my grad. Thanks!
You explained this better than any site I've come across. Thank you.
So this is the "old" Engineering Explained that everybody seems to love so much.
I'm guessing this is a V10 (or at least a V8.) In this case, it uses two air filters so that there is a dedicated air filter for each cylinder bank, maximizing air flow. This is fairly common with V style engines, though I would say many lower performing engines probably stick with just a single filter.
Yep, with emissions and fuel economy regulations getting more and more strict, companies are forced to make smaller and more efficient engines. If they want to maintain power while achieving those two goals, turbos are the way to go!
this is the second video i watched from you, and you earned a new subscriber! I have been obsessed with cars ever since i was a kid, and now I am finally starting to understand how they work. Just gotta get back to studying for my final now and graduate in 3 years and get that mkIV supra! Just curious if you are an engineer or just know a lot about cars? Thanks and keep up the good work
The ECU uses sensors (MAP, IAT, MAF you can search my channel for these) to alter the air/fuel ratio. It will keep it in a tolerable range.
Damn. Where it all started. Congrats man.
im a mechatronics engineer and i love cars , and i really like your videos ; u explain the basics of a car easiely , keep posting more videos
Well done. Exactly what I was looking for and clearly explained.
You are the best! I learned how a turbo works thanks to you, and in just 5 minutes!! Thank you for the explanation greetings from argentina
Thanks for watching!
Yes, but this is countered by greater combustion resulting in a larger force on the piston during the power stroke.
10 years later, I'm proud of you man!!!
@sage1wt The exhaust leave the engine, so no, it does not make another cycle through the engine (cylinder). However, since most engines use EGR (exhaust gas recirculation) some of the exhaust actually does go back into the engine. This is for emissions purposes, and I will eventually have a video on this topic.
The CR is lowered when a car has a turbo so that the effects of the added pressure are reduced. This prevents knock.
thats it! im subscribed! your videos are awesome bro!
iTzWhuteverZ Thanks!
Short and straight to the point, thanks!
I am high and stupid and I get what you are explaining kid! Great JOB! Amazing for people from different fields that what to make sense of some engineering.
I just found your channel. Amazing. I'm watching every video.
KMR TV still watching???
He is better than my college teachers. I am glad to see your first video.
Thank you so much sir, all your videos are just great. You explains everything perfectly in simple language that any body can understand.
Boost does not directly change the compression ratio, but boosted engines typically have lower CR to compensate for the higher pressures. Max revs are lower because turbo'd engines can produce much more power at lower RPM than NA engines.
since I am new in this area i can only think on saying thank u to you for your videos , thanks again
Awesome name by the way. Can't wait for May 23rd!
Yes, the car will use more gas, but if you use a smaller engine because a turbo increases the thermal efficiency of the vehicle, then you can achieve better mpgs assuming you're not flooring it.
I love your videos, man. I wish you were a hologram that could be projected for different subject in classrooms around the world.
First question: it will decrease your torque, but increase your theoretical top speed, if you have enough power to get there. Second question: Because tires sink into the asphalt, and wider tires have more area to sink in. The F=uN is not a perfect equation, just an idealized equation that gives you a good general idea of the friction forces involved.
congratulations 1 million plus subscribers really inspired how far you have come
Your diagrams have got much better 😄
thanks for your amazing video once again, no bull crap introductions sadly youtube has been caught up in this... straight to the point.
So many cars are going turbo on the market or twin turbo over larger engines
It can be, but if you're flooring it constantly, or using the turbo for additional power rather than efficiency, obviously your mpg will vary accordingly.
It's because the boost is described as gauge pressure (pressure increase over atmospheric). If it were absolute pressure (this includes atmospheric) it would be the amount of boost added to 14.7 psi.
Old videos are fun to watch!
You're very welcome, thanks for watching!
You should be that you want to learn, rather than learn. Good for you!
nicely explained.....much better then any teacher in india...
Your first video, yet, very well explained.
I am perusing under graduate in automobile n Sir. Jason make me every topic understandable for me. Thankyou sir.
you've got some interesting videos mate.good to see someone that's not just into burnouts. are these videos work or pleasure? just remember its not an explosion.
I will be releasing two videos on anti-lag systems in early October. :)
You're welcome, thanks for watching!
@joeslimon Apologies, I tried to make it clear by saying 15 (or whatever number) psi "of boost" so that it is seen as additional.
One of the pioneer carrtuber cher
A turbo forces in more air, more air means pressure rises. Air has O2 in it, so if there's more air, there's more oxygen.
Bro can you do a overfilling gas tank video you don't have one and alot of people don't please make one it would be aswome
@imthaman1234 No, the exhaust gas is used to spin a turbine which brings in fresh air. Sorry I may have made it a tad confusing, watch my video on turbochargers and it should clear things up.
Yes, it does increase efficiency, but don't think you won't use more fuel if you turbo your car. You will if you push it up into high RPM - double the air means double the fuel is burned. Since it's more efficient, yes, greater mileage is possible.
I am new to this channel and starting with the first video
I went back to find your first vid haha.
Yes. A supercharger is belt driven and a turbocharger is exhaust driven. They increase power based on the same principle though; increase the amount of air going into the engine.
man your videos are awesome.
i would really like to become a car mechanic and these videos explain in detail a lot about cars
thanks for making the videos!!
You could link the two headers together eventually. I believe the new F1 engines for 2014 will be V6's linked to a single turbo.
why dont you get more veiws? I have always wanted to take a class or two about engines at my high school; although, there is no need to because you have "explained" Everything I want to know. Thanks You
Yes, I intentionally scrolled to the first upload to see how long you've been brilliant - this is your firs upload, right..? Hope life smiles upon you to get more toys and tech so that you can keep up the content. Don't tire. We enjoy it, even if we just watch from the shadows and never say anything to a fellow engineer.. :D
Be good.
Be different.
Be nice!
The reason a smaller engine is used is to save fuel. The reason the turbocharger is used is to compensate for lost power by reducing the engine size. Overall, the engine is more efficient, however if the turbo were removed, and less air were entering the cylinders, less fuel would be burned per cycle, and an overall greater mileage would be possible. However, since more power is necessary to accelerate the large mass of a car, the turbo is used for a power boost.
Dude look at this versus, the new videos!!. Your hair cut has improved!! Improved hair dynamics and you look better!
@SoyAussie Well the intention is to increase power by increasing the mass of air in the cylinders so that you can burn more fuel. However with a smaller engine that is turbocharged, you can create equivalent power to larger engines, and get better fuel economy when you want to (just don't floor it and shift early).
There is a difference in volume; 1.8 liters vs 2.0 liters. Based on volume alone, you cannot say which is "faster" (produces more power) or the gas guzzler of the two, though rule of thumb larger engines will have a bit more power, and will use more gas.
You've come along way. I really enjoy your vids, thanks !
Combustion may not hold meaning to the masses, where as explosion does. Though I am still learning the terminology, I try to make my videos as easy to understand as possible. Also, having many foreign viewers, it's good to keep the vocabulary basic. I know the term combustion quite well my friend. :)
So the exhaust pressure from the cylinder is used to bring in more Air (by spinning a tubine) right? So is the exhaust waste is confined from the air; therefore, the exhaust doesn't make another cycle through the cylinder?
What a great video! I wish I knew more about this stuff
By increasing torque (assuming all else remains equal) you will also increase HP, so both.
Hypothetically If intercooler pipping was increased from 2" to 2.5" or even 3" the cfm would remain the same but the psi would drop. Would the lower psi safeguard the engine? Does less psi mean less stress? Or is it all really about the cfm?
A couple things that really stuck with me when I was learning the fundamentals of turbocharging are 1) The more basic thermodynamic properties of petroleum and 2) Average cylinder pressure.
Typically premium (as high octane as possible) since they have high pressures/temperatures within the cylinder.
Jason, just want to clarify for my understanding. When you say at 1:27 that you have doubled the psi when atmospheric pressure is 14.7 psi and boost is 15 psi (in your example), however that is not double. Unless you mean to say that atmospheric is 14.7 psi absolute pressure and boost is 15 psi gauge pressure=29.7 psi absolute pressure. Just checking.
