Five and a half minutes to describe a Veyron engine?! Astonishing! I may have said it before but you are truly the Brian Cox/David Attenborough of automotive engineering! Yours are by far the most straightforward, accessible, concise and comprehensive tutorials/reviews I've seen.
Not trying to be harsh on anyone but this is Engineering Explained, and automotive engineering is not just about how to make more power. It's not like the engineers at VW just walked into the executive's office and say "give us some VR6s and we will make a 400 km/h car by throwing two titan turbos in it".
Excellent videos! You're really good explaining all car components. Could you explain the different types of variable valve lift systems? And one more thing... You should make some videos about electric cars, that would be awesome! Greetings from Mexico!
I imagine if you had a camera in there and could see all the rods in the crankcase flying around, it would look like a Tennessee tornado tearing up a trailercourt on spaghetti night.
Its an epic piece of engineering. A relatively compact engine that isnt stressed despite its massive smooth power and torque. They Veyron is a master class of car design with aircraft performance all within a luxury cocoon of a Bentley and some. If anyone compares this to the kit car Hennessey (which it is in comparison) you are severely mistaken. Refinement, speed, power and handling are the hardest to achieve; just look at Concorde, she aced that. Big time.
+Ian Thompson Yea but a double bank V16 dose not roll off of the tongue as nicely as W16. Plus since there isnt another Engine like this they can call it what ever they want.
i love how they call this engine a w-16 when it is clearly a compound v-16; a true w-shaped block has 3 banks of cylinders off of a single crankshaft, looking just like the letter w, not like the letter v...
Engineering Explained Seriously? I mean you chose to go to mechanical engineering and you never had interest in cars? I studied in University of Bath, but cars were always my passion..i bought a nissan 200sx (s13) with my savings without anyone knowing in the start:p Still modifying..now upgrading to VAG ignition coils for xmas :))
St0RM33 Uhm... Hate to break it to you my friend but not all mechanical engineers become automotive engineers, which is what you're thinking of. While cars are great examples of mechanical engineering applied, basically any type of machinery you can think of has a mechanical engineer's touch... From biomedical devices to engines, from industrial equipment and tools to rockets. I've even seen mechanical engineers who have careers doing things like running power plants. Typically (Though not always, just in my experience) HVAC engineers also studied mechanical engineering, as ME's have to take a -ton- of thermal fluid science courses. There's a -lot- more to mechanical engineering than just automotive engineering.
+SupaDriftz Most Motorcycle race engines have a gearing shaft inside the engine crankcase which for a inline engine is fine, but for a V type engine, the nose side of the engine (bank closest to the front) has more resistance against it. Honda attempted (properly well) to counter act the resistance by adding another cylinder on the nose side to give more torque against the turning gears. The result actually gave way more torque then desired, and without the advanced level of traction control that we have now made it quite overpowering sometimes. Thus it was ditched.
What I don't understand is how Honda, Kawasaki, or Yamaha hasn't developed a VR4 or VR6 for a motorcycle yet. This seems like a great idea and platform for a 1000 or 1500cc engine.
I'd pay $12.00 to see someone put a W16 in a Golf VR6. they could mount it at the back , remove the seats and do some very smart adaptations but I'd pay either way to see it work
+kapil busawah Already been done with a W12! VW made a concept car for a bit of fun. The results were... well lets just say there is a reason they never put it into production. There is an episode of Top Gear which featured it a few years back!
A naturally aspirated W16 obviously. There's no way the golf could take that much power, or even fit 4 turbos in the engine bay (or behind the drivers seat).
I like your video's being exactly long enough to explain your point. Many RUclipsrs are forgetting this and it is irritating to listen to their boring fairy tales. Well done!
That's kind of awkwardly worded, but essentially correct. However, that's normal for a ICE. It's down to the thermal efficiency which happens to be around 30%.
it normal for petrol engine, 25-35% for combustion energy turn into mechanical energy, it happens on all petrol engine. you wanna go efficient, go for diesel.. efficient of engine is much depend on compression ratio. that call thermal efficiency.
I think another con is the amount of intercoolers/radiators it needs and all the tubing to accommodate them as well. Added even more weight/complexity.
Another benefit of this many cylinders is small cylinder size -> Relatively stronger as each combustion event holds less energy, hence the base engine is going to be more durable. Per cylinder size is 0,5l
Thanks for another interesting video! I'd really appreciate if you could help me understand the firing order logic (for any engine size). I always feel like the forces applied to the crankshaft and the heat dissipation through the engine block will be messed up, so why are firing orders the way they are?
It's certainly easier to understand on engines with fewer cylinders. It comes down to the crankshaft design, layout, and number of cylinders. Basically there are only so many options which would phyiscally work (piston fires ever "x" degrees of crank rotation, piston "a" is on an upward stroke, which means it's either exhaust or compression, sort the FO in a way that allows for each of the cylinders to fire in a balanced fashion. Maybe check out my videos on I4 or I6 where I go a bit more into detail on the firing order. This was more focused on how it works as it's a massive complicated engine.
The only type of engines I have any knowledge on are 2-strokes and that is just a hobby. I thoroughly enjoyed this walk-through, specifically how provided intent and placed each of the components in to connect. Great job!. If you have not taken a look at the little glow engines for rc cars, they can RPM. If you have not you should check them out, I imagine you would enjoy!
16 cylinders on one crank attacking it on all 4 sides. not just two on a longer V-16 crank. That W crank is going to be under a shitload of cooks in the kitchen. not enough waitresses unless the crank is a sturdy wider than a V block's crank of any variety. I'd go with an alloy that compliments flexibility and strength for the crankshaft.
I dont know so far in anybody already commented about it, but there seems to be a small mistake in the video. You mention individual fuel injection, but it is in reality a direct injection engine. The information happens to be at around 1:40. With direct injection there will be no air-fuel mix before the intake valve. The mix of air and fuel will be made inside the combustion chamber shortly before the actual combustion. Maybe you leave a short comment here and tell me what you think about that issue 😉
So we can say that if the Veyron was lighter like 1400-1500kg it would still be the fastest car in the world and probably even beyond.. It weights almost 1900kg! That's a lot and that's why Koenigsegg and Henessey (corvette+lotus) managed to make a better acceleration car, also top speed (which Koenigsegg only claims, it's not proved).
Despite what people think, Veyron is not all about speed. Just because it was the fastest car in the world (and still is as far as production cars go, exluding tuned ones like Venom), doesn't mean it's the main purpose. I had a short ride in one as a passenger on an airfield, a regular Veyron, not SS, and it was the most amazing combination of luxury and speed. What makes Veyron better than any other hypercar is the fact that it's a luxury grand tourer, it's a track car, or a record breaker. It's a VERY comfortable, refined, quiet car. It's more comfortable than a Bentley Continental GT or a Mercedes CL, or any similar big grand tourer coupes, and still much faster. Also, it's extremelly easy to drive, very smooth, very stable, very secure, etc. Basically, it's not about the number it produces, it's about HOW it produces them and translates them into real world. No other car accelerated that fast with so little effort. At about 200 km/h it literally feels like you're going 50, it's super quiet, stable like on train rails, and there's very little noise inside. For example, Ferrari 458 feels like it has no sound proofing whatsoever in direct comparison, and it rides like it doesn't even have a suspension. Veyron is as smooth as butter. That's what makes it as good as it is. It's extremelly hard to engineer a car that will be as fast as it is, but also as luxurious as it is. Much harder than just making a really fast car, which is actually quite easy to do nowadays. Everyone can get 1000hp+ out of an engine today with some simple tuning.
derbigpr500 I would not call the Veyron a track car. Tires are too stupid expensive, its to heavy, and its not all that great in the handling department. Its an impressive car if your into that kind of thing, but I would be much happier in an Ultima, or SL-C for 1/20th the cost, and brutally fast. The Veyron is more about blatant displays of excess than sheer performance. There is no race track on the world where you get close to top speed in the Veyron, and its plain useless on a public road for anything other than dick waving.
Veyron is a showcase of engineering capability. Performance of super cars stagnated for almost a decade since the glorious days of Porsche 959, Ferrari F40, Jaguar XJ220, and later McLaren F1. Nobody's trying to break 400 km/h on a road-going car before VW decided to do a show of force (when it's aggressively expanding into the luxury market). And Veyron is the first one to trigger a new round of top speed arms race. Since it's the first one there of course it's going to be overtaken by later competitors. Just because the Russians didn't land a man on the moon doesn't mean they are bad at building rockets; they are the first to go to space and are the only ones capable of sending men to ISS today. Veyron is similar.
There is no such thing as a VR8. This is a W motor, while it shares similarities to the VR platforms they are two completely different animals. It would be like you, which you did, comparing a VR6 to an IL6....... All of that aside this is a good video, and breakdown explanation of the W16 Quad Turbo. Keep up the good work.
Thanks for the video! I requested it and it's cool to see a big channel listen to those 2 or 3 people who asked for a video/idea. Great work! I remember vw was so proud of 1000 hp some years ago, while daigo saito (drifter) has 1200 hp on 6 cylinders now (not reliable though xD)
They can call it whatever they want but it's not a "W16". 2 "V's" is a "W" but only if they actually form a "W" which this engine does not. They can call it the "God Engine" if they want but that don't mean that's what it really is. I guess it's just this generation where anything can be whatever it identifies as. Regardless of common sense. The only place I've ever seen a true "W16" is at a tractor pull competition where they actually run 2 V8 engines together synchronized side by side into a single transmission. The problem with a "W" configuration is it's inherently too wide for use on the road unless it can be made extremely small. There was a an attempt to build an "X16" engine back in the late 90's to address this issue. I never seen it online. I've only seen it on a brochure. The "X16" was great idea in theory. It was compact. It was 2 "V8's". One is upside down welded together at the block eliminating the oil pan and they shared a common crank. But in practice it must have failed horribly. I don't know what happened with it. I can't even find any trace of it online. I think they ran into a massive problem and couldn't overcome the fact that engines don't like to run upside down.
EminentLeague Older ones spin a wire that spins a gear that's connect to a larger gear behind the speedo, the ratio of gear 1 vs gear 2 has to be matched to your final drive ratio (ratio of transmission gears + rear end ratio + tire size) to show real speed. Changing any of those without re calculating the ratio needed for speedo gear and replacing it will result in an incorrect speedometer. Newer cars use optical sensors to count revolutions per second of the final drive by measuring the drive shaft rotations and then do some math for in the ECU and spit it out to a digital read out or apply a specific amount of current to the speedo wire to move the needle.
It is said you get 1000 hp of output power but to get this result the engine must produce 3000 because 2/3rd of the power is lost by heat so it needs 11 radiators to cool it
VWs VR6S LOVE boost amd can make over 1000 hp on just 6 cylinders. The Veyron uses 16 of them and FOUR turbo chargers.... Now ik say a twin turbo may give a V6/V8 even,smooth power. While a big single will provide more top end HP but have a more "violent" torque curve. Even if a Veyron engine was built and ran 2 huge turbos instead of the 4 it has stock or simply just 4 bigger turbos it SHOULD be able to stand in the 2500-3000hp club. But I dont even want to know the price tag to make that happen would be
So this engine really only uses 4 camshafts? Aren't these close to 2 inline 8 cylinder engines with the offset that a vr6 normally has? If so, inline 8 cylinder engines died by the 50s because of how much stress they had resulting in very unreliable engines, then what Has VW done to prevent this from having the problems early engines had?
16 cylinders is an interesting number. You might like to compare the 1.5 litre, crankshaft driven centrifugal supercharger, 500-600 BHP BRM engine of 1950-52. W is also an interesting cylinder configuration. I don't think this VW engine is really a W. That would be one of the aero engines of the 1930s such as the Napier Sea Lion of 24 litres which powered the Napier Railton special which held the Brooklands lap record at 143 mph in 1936.Parhapsyou would like to discuss those?
everyone saying the veyron should be a v8 because v8s are capable of making big power don't understand the point of this car. this car has to be the be all and end all of a luxury-performance gran tourer (with added exclusivity). a 16 cylinder with 4 turbos only seems fit. think how little effort each of those cylinders is putting in to achieve that 1200hp figure
I thought that the cylinder banks would be mirrored. Like you'd see in a v8 with intake in the middle and exausts on the outsides. You stated that each bank would have intake on the left and exaust on the right side. Don't get it how that works.
I could be wrong but, i thought a guy on the tv (documentairy about the veyron) said the engine makes 3000 to 4000hp but they had to "down tune" it to 1001-1200. (i thought it was because of the heat, if so, you forgot to add it to the cons lost). anyways nice video, hope you replay to my question Engineering Explained
It could probably easily handle 3000-4000hp, but it wouldn't be as reliable or longlasting, that was the point with the engine. When they engineered it they focused on making it indestructible. My mechanics professor back at engineering university talked about it, since he knew people from VAG who worked on the project, he used to work for them, and their goal was to make that engine work for more than 1 million km's without any problems and perform exactly the same at that point as when it was brand new, with just the regular maintenance that all other cars get, which is very rare as far as supercars go. For example, you can be damn sure that something like a Venom will need it's engine rebuilt or heavily serviced after about 50,000 km's because it's overtuned and underengineered. Veyrons engine is the opposite, it's very overengineered, it's deep within the safe zone in all parameters.
I have heard, that this engine could make 3-4000hp in theory, but it would be impossible to get enough radiators on a car to cool it, so it is restricted to about 1000hp.
This engine could push that easily, but Bugatti designed the Veryon with extreme reliability in mind, but to also have extreme speed. Yes, these engines are 'tuned down' to give it that reliability factor. You could get an engine like this to push 2700-3500hp, with a lot of money, work, and time; but that throws reliability out.
I hate it when people call this car underpowered for having 16 cylinders. If I'm not wrong, displacement and RPM play a bigger role in torque/power figures than the number of cylinders, so theoretically the Dodge Viper should have the most power of a stock engine (8.4L), no? Please help me understand this so I can defend the Veyron more adequately from insults from idiots.
When I first heard about the Bugatti engine I assumed they literally took 2 x v8 's and joined one behind the other! I kept wondering surely that'd be a bit long & no wonder they say it's heavy!
cost and fuel efficiency/emissions related reasons, now that Rimac owns Bugatti, theyll probably be quad turbo V12 or V10 cars now with smaller displacements, and insane electric motors added on top, expect something north of 2000AWHP per new PHEV Bugatti Rimac car to come out
Thank you for your videos EngineeringExplained, I enjoy them. Just curious though, are you positive that one cam is for intake and the other is for exhaust? Looking at pictures of old VR6 motors, it looks like one cam controls all of the valves on one bank, the other cam controls all of the valves on the other bank. Anyway, thanks for the videos.
I know it's not applied in automotive industry, but, can you explain about radial engines? Thanks, like your channel. Another interesting engine was the W18 that bugatti used in some concept cars.
I believe there's something wrong in your math, for power; one cylinder will fire every 22.5 degrees, which is 2 powerstrokes per 45 degrees. (16 fires for one revolution)
Five and a half minutes to describe a Veyron engine?! Astonishing! I may have said it before but you are truly the Brian Cox/David Attenborough of automotive engineering! Yours are by far the most straightforward, accessible, concise and comprehensive tutorials/reviews I've seen.
"You gotta work with the stroke more than you usually would" 5:26. exactly my thought when my gf left me.
Goriaas
Best comment ever :D
Lol, the firing order was so long you didn't even read it
Ain't nobody got time for that.
Not trying to be harsh on anyone but this is Engineering Explained, and automotive engineering is not just about how to make more power. It's not like the engineers at VW just walked into the executive's office and say "give us some VR6s and we will make a 400 km/h car by throwing two titan turbos in it".
I love how the firing order takes up more than half the board
Excellent videos! You're really good explaining all car components. Could you explain the different types of variable valve lift systems? And one more thing... You should make some videos about electric cars, that would be awesome! Greetings from Mexico!
+Efraín Gustavo Barragán Jácome I have a whole playlist on electric cars! :) ruclips.net/p/PL2ir4svMoaYj48N0VWoic25P9LaU2wlbA
That's perfect. Thanks!
Good vid.. I have an idea for your next video if you're running out of ideas. How about a top 5 unconventional engine designs?
As an engineering feat it is impressive.
The W8/W12/W16 share the same crank
@Valkyrie 007 check out the Wizards channel, he talks about it on there.
@Valkyrie 007 oh. Profile change. I have a jesko and you have a chiron. Haha!!
I imagine if you had a camera in there and could see all the rods in the crankcase flying around, it would look like a Tennessee tornado tearing up a trailercourt on spaghetti night.
Mate,I've never seen the workings of a motor explained as well as you can do it. Great video.
A lot of people don't see why VW uses such a big engine. There weren't any engines at the time that could make 1,000+hp reliably.
damn you are right
but muh supra!!!
Its an epic piece of engineering. A relatively compact engine that isnt stressed despite its massive smooth power and torque. They Veyron is a master class of car design with aircraft performance all within a luxury cocoon of a Bentley and some. If anyone compares this to the kit car Hennessey (which it is in comparison) you are severely mistaken.
Refinement, speed, power and handling are the hardest to achieve; just look at Concorde, she aced that. Big time.
+peanuts2105 I agree! Although I am quite fond of the Swedish contender too -- it's a bit more raw and aggressive.
I never liked how it was called a w16. Since it doesn't have 3 banks
+Ian Thompson I see where you are coming from, but what do you get when you put 2 V's Together - vv (W)
Ethan Gee I guess it should be called a double bank V16 or something. Since it is a V, but with two extra rows
+Ian Thompson Yea but a double bank V16 dose not roll off of the tongue as nicely as W16. Plus since there isnt another Engine like this they can call it what ever they want.
weirdstuffanimation7 Fair enough
Well it has 2 Banks with Cylinders on the two outsides .. But the build of 2 V is resultung to W , so 3 Banks .
i love how they call this engine a w-16 when it is clearly a compound v-16; a true w-shaped block has 3 banks of cylinders off of a single crankshaft, looking just like the letter w, not like the letter v...
Very interesting...got a chuckle on the 'stupid expensive' note you made.
Thanks for this.
I once saw a Veyron live and that's a really massive engine. Together with the transmission it weighs over half a ton
As a first year mechanical engineering student, I am ashamed to think that I once thought a W16 was two V8 blocks side by side...
Don't be ashamed. I didn't know anything about cars when I was a freshman in ME.
same XD

Could you explain how Honda had a V5 engine in their RC211V MotoGP bike?
+SupaDriftz Most Motorcycle race engines have a gearing shaft inside the engine crankcase which for a inline engine is fine, but for a V type engine, the nose side of the engine (bank closest to the front) has more resistance against it.

The result actually gave way more torque then desired, and without the advanced level of traction control that we have now made it quite overpowering sometimes. Thus it was ditched.
I've always been curious about if the different runner lengths produce different results, or if being turbo charged negates that issue.
What I don't understand is how Honda, Kawasaki, or Yamaha hasn't developed a VR4 or VR6 for a motorcycle yet. This seems like a great idea and platform for a 1000 or 1500cc engine.

Bugatti Veyron actually produces around 3000 horsepower but around 2000 disappears with heat
That's kind of awkwardly worded, but essentially correct. However, that's normal for a ICE. It's down to the thermal efficiency which happens to be around 30%.
it normal for petrol engine, 25-35% for combustion energy turn into mechanical energy, it happens on all petrol engine. you wanna go efficient, go for diesel.. efficient of engine is much depend on compression ratio. that call thermal efficiency.
First law of Thermo-dynamics.
25-30% isnt 2/3s tho... That statement is false
Its tuned down to avoid being overheated its not losing 2k hp from heat
I been waiting for this! Thank you.
I will definitely be back for more of this channel. Thanks man
You should do a video on how glow plugs work vs spark plugs
Bugatti: I know how to count to two with the ignition! Watch- 1-14-9-4-7-12-15-6-13-8-3-16-11-2 Nailed it!
"there's some math if you're into it" hahaha

Since the W16 is effectively two VR8s joined at the crank, I am a bit surprised they didn't produce a VR8. Or did I miss that?
16 cylinders on one crank attacking it on all 4 sides. not just two on a longer V-16 crank. That W crank is going to be under a shitload of cooks in the kitchen. not enough waitresses unless the crank is a sturdy wider than a V block's crank of any variety.

Can you make a video about radial engines? I know that they had been mainly on old planes, not on cars, but i think are pretty interesting!
Another great video from Engineering Explained, thanks again buddy!
beautiful engineering
Probably my favorite advantage is the engine firing every 45 degrees. Just...holy flip, firing over 860 times a second when it's almost max RPM...
Hat off to ya!! Really like these videos explaining this stuff.
So we can say that if the Veyron was lighter like 1400-1500kg it would still be the fastest car in the world and probably even beyond.. It weights almost 1900kg! That's a lot and that's why Koenigsegg and Henessey (corvette+lotus) managed to make a better acceleration car, also top speed (which Koenigsegg only claims, it's not proved).
Less weight means better acceleration, doesn't influence the top speed much.

derbigpr500 Exactly. You get the biggest THUMBS UP ever. I totally agree with you. That's why it costs +1 Million EUR...
derbigpr500 I would not call the Veyron a track car. Tires are too stupid expensive, its to heavy, and its not all that great in the handling department. Its an impressive car if your into that kind of thing, but I would be much happier in an Ultima, or SL-C for 1/20th the cost, and brutally fast. The Veyron is more about blatant displays of excess than sheer performance.

Veyron is a showcase of engineering capability. Performance of super cars stagnated for almost a decade since the glorious days of Porsche 959, Ferrari F40, Jaguar XJ220, and later McLaren F1. Nobody's trying to break 400 km/h on a road-going car before VW decided to do a show of force (when it's aggressively expanding into the luxury market). And Veyron is the first one to trigger a new round of top speed arms race. Since it's the first one there of course it's going to be overtaken by later competitors.
Just because the Russians didn't land a man on the moon doesn't mean they are bad at building rockets; they are the first to go to space and are the only ones capable of sending men to ISS today. Veyron is similar.
IIIIII LOOOVE YOOOOUR VIDEOOOOOS DAMMIIIIT!!!
+riKringkast Thanks!!
so cool ,thanks for the cool videos !
Once again, great video. :)
Excellent. Become easy now
Thank you for the really interesting information!
Thanks a lot mate.......bless your heart. Been wondering how they made it...
There is no such thing as a VR8. This is a W motor, while it shares similarities to the VR platforms they are two completely different animals. It would be like you, which you did, comparing a VR6 to an IL6....... All of that aside this is a good video, and breakdown explanation of the W16 Quad Turbo. Keep up the good work.
Yes there was a vr8 in some Passats. It was longitudinally mounted.
I want this on my Fiat Panda
can you make a video on rotary engines? along with the advantages/disadvantages of having one.
This is requested every time I post an engine video. ruclips.net/video/umxGxsN5vQM/видео.html
awesome, thank you!
wow this is Amazing
Good video.. Need you a laser pointer..
Thanks for the video! I requested it and it's cool to see a big channel listen to those 2 or 3 people who asked for a video/idea. Great work! I remember vw was so proud of 1000 hp some years ago, while daigo saito (drifter) has 1200 hp on 6 cylinders now (not reliable though xD)
I think I've probably had a few hundred requests for it, however, yours was the only one I took into consideration. Or something. :)
If the veyron was a v8 with 1000 hp, it would overwhelm the cilinders and break down every tine
Hi dear, It is not a doubleyou (W) 16 motor, it is a DOUBLE V V 16 MOTOR. As two V8... NICE WORK.
Steady stunting with that play button
They can call it whatever they want but it's not a "W16". 2 "V's" is a "W" but only if they actually form a "W" which this engine does not. They can call it the "God Engine" if they want but that don't mean that's what it really is. I guess it's just this generation where anything can be whatever it identifies as. Regardless of common sense. The only place I've ever seen a true "W16" is at a tractor pull competition where they actually run 2 V8 engines together synchronized side by side into a single transmission. The problem with a "W" configuration is it's inherently too wide for use on the road unless it can be made extremely small.
There was a an attempt to build an "X16" engine back in the late 90's to address this issue. I never seen it online. I've only seen it on a brochure. The "X16" was great idea in theory. It was compact. It was 2 "V8's". One is upside down welded together at the block eliminating the oil pan and they shared a common crank. But in practice it must have failed horribly. I don't know what happened with it. I can't even find any trace of it online. I think they ran into a massive problem and couldn't overcome the fact that engines don't like to run upside down.
Another cool video. I wonder to whom should we pay the fees for learning so much things about almost anything.
I wish Bugatti would make a two stroke diesel version. She would sound beautiful.
I can imagine the smoke it would produce, they would have to call it bugati octopus
Wow, didn't know the W16 was 64 valve
Hey you should do a video on how speedometers work! Like how they accurately measure your speed.
EminentLeague Older ones spin a wire that spins a gear that's connect to a larger gear behind the speedo, the ratio of gear 1 vs gear 2 has to be matched to your final drive ratio (ratio of transmission gears + rear end ratio + tire size) to show real speed. Changing any of those without re calculating the ratio needed for speedo gear and replacing it will result in an incorrect speedometer. Newer cars use optical sensors to count revolutions per second of the final drive by measuring the drive shaft rotations and then do some math for in the ECU and spit it out to a digital read out or apply a specific amount of current to the speedo wire to move the needle.
It is said you get 1000 hp of output power but to get this result the engine must produce 3000 because 2/3rd of the power is lost by heat so it needs 11 radiators to cool it
Very cool! Thanks for the explanation. Now do some push ups!
I love your vids. I was wondering if you could make a video about the theoretical use of rotary engines in a car
Nice plaque, bro.
Please do a single cylinder explained.
I'm at that point when I like the video before I even watch it.
how does it compares with a custom skyline 6 cylinders engine like, that can produce 1000hp too?
VWs VR6S LOVE boost amd can make over 1000 hp on just 6 cylinders. The Veyron uses 16 of them and FOUR turbo chargers.... Now ik say a twin turbo may give a V6/V8 even,smooth power. While a big single will provide more top end HP but have a more "violent" torque curve. Even if a Veyron engine was built and ran 2 huge turbos instead of the 4 it has stock or simply just 4 bigger turbos it SHOULD be able to stand in the 2500-3000hp club. But I dont even want to know the price tag to make that happen would be
So this engine really only uses 4 camshafts? Aren't these close to 2 inline 8 cylinder engines with the offset that a vr6 normally has? If so, inline 8 cylinder engines died by the 50s because of how much stress they had resulting in very unreliable engines, then what Has VW done to prevent this from having the problems early engines had?
Bugatti engine explained by young BETO O'ROURKE.....cool
thanks for a very good explanation... Joachim Lowe
Any chance you can show us how F1 pnewmatic recall valve work. I have read some article but they were vague at best. Kudos on the videos.
+thezackseven ruclips.net/video/SJs_64Aj4Ho/видео.html
16 cylinders is an interesting number. You might like to compare the 1.5 litre, crankshaft driven centrifugal supercharger, 500-600 BHP BRM engine of 1950-52. W is also an interesting cylinder configuration. I don't think this VW engine is really a W. That would be one of the aero engines of the 1930s such as the Napier Sea Lion of 24 litres which powered the Napier Railton special which held the Brooklands lap record at 143 mph in 1936.Parhapsyou would like to discuss those?
Imagine if they used the 5 valve like the 1.8t that's 80 freaking valves lol alot of moving parts at only 64 valves
Hey Brian Cox earth's definitely flat pal.
Can you do an episode on lightened flywheel?
Carlo Saclayan I have a couple on rotational inertia, this is a good start: ruclips.net/video/CxuER0qIWJk/видео.html
Ever since the W12 came out I've been wondering how they get adequate bearing area on the crankshaft main and rod bearings?
everyone saying the veyron should be a v8 because v8s are capable of making big power don't understand the point of this car. this car has to be the be all and end all of a luxury-performance gran tourer (with added exclusivity). a 16 cylinder with 4 turbos only seems fit. think how little effort each of those cylinders is putting in to achieve that 1200hp figure
Can you do a video on how a spool works?
Can you please do a video on Piston Rings!! !
I thought that the cylinder banks would be mirrored. Like you'd see in a v8 with intake in the middle and exausts on the outsides. You stated that each bank would have intake on the left and exaust on the right side. Don't get it how that works.
Jason, I believe it's made up of two W8 4.0L. The VR8 doesn't exist, but W8 4.0L powered Passat W8. Two W8 4.0L = W16 8.0L
Nothing mentioned about W16 balance? Is it perfectly balanced like the V12?
Better balanced
I could be wrong but, i thought a guy on the tv (documentairy about the veyron) said the engine makes 3000 to 4000hp but they had to "down tune" it to 1001-1200. (i thought it was because of the heat, if so, you forgot to add it to the cons lost). anyways nice video, hope you replay to my question Engineering Explained
It could probably easily handle 3000-4000hp, but it wouldn't be as reliable or longlasting, that was the point with the engine. When they engineered it they focused on making it indestructible. My mechanics professor back at engineering university talked about it, since he knew people from VAG who worked on the project, he used to work for them, and their goal was to make that engine work for more than 1 million km's without any problems and perform exactly the same at that point as when it was brand new, with just the regular maintenance that all other cars get, which is very rare as far as supercars go. For example, you can be damn sure that something like a Venom will need it's engine rebuilt or heavily serviced after about 50,000 km's because it's overtuned and underengineered. Veyrons engine is the opposite, it's very overengineered, it's deep within the safe zone in all parameters.
I have heard, that this engine could make 3-4000hp in theory, but it would be impossible to get enough radiators on a car to cool it, so it is restricted to about 1000hp.
This engine could push that easily, but Bugatti designed the Veryon with extreme reliability in mind, but to also have extreme speed. Yes, these engines are 'tuned down' to give it that reliability factor. You could get an engine like this to push 2700-3500hp, with a lot of money, work, and time; but that throws reliability out.
I hate it when people call this car underpowered for having 16 cylinders. If I'm not wrong, displacement and RPM play a bigger role in torque/power figures than the number of cylinders, so theoretically the Dodge Viper should have the most power of a stock engine (8.4L), no? Please help me understand this so I can defend the Veyron more adequately from insults from idiots.
When I first heard about the Bugatti engine I assumed they literally took 2 x v8 's and joined one behind the other! I kept wondering surely that'd be a bit long & no wonder they say it's heavy!
nice vid mate
so basically it is 2 VR8 cylinder heads mounted to a V block and then they have fitted 4 turbo chargers on that? 2 turbos on each cylinder head?
+Philip Grundemar I believe it's more like two W8s matched together, or 4 VR4s, but essentially yes. 1 turbo for each VR4.
Would an inline 6 engine be more efficient because it fires every 120 degrees compared to 45 degrees?
so my question is why is it the last BUGATTI W16 Engine? why did they stop making it?
cost and fuel efficiency/emissions related reasons, now that Rimac owns Bugatti, theyll probably be quad turbo V12 or V10 cars now with smaller displacements, and insane electric motors added on top, expect something north of 2000AWHP per new PHEV Bugatti Rimac car to come out
Thank you for your videos EngineeringExplained, I enjoy them. Just curious though, are you positive that one cam is for intake and the other is for exhaust? Looking at pictures of old VR6 motors, it looks like one cam controls all of the valves on one bank, the other cam controls all of the valves on the other bank. Anyway, thanks for the videos.
my apologies, looks like you were right. the pictures of the vr6 motors that I had seen are older 2 valve/cyl. thanks for the videos EE
It's time to make a modern video
Cool shiny plaque on yer wall
I was hoping someone could explain how the 2 camshafts per bank actuated the valves that are so close to each other
He has a video on the VR6 engine which explains.
Can you do a video on V16s? And why they sound so odd...
I know it's not applied in automotive industry, but, can you explain about radial engines?
Thanks, like your channel.
Another interesting engine was the W18 that bugatti used in some concept cars.
I believe there's something wrong in your math, for power; one cylinder will fire every 22.5 degrees, which is 2 powerstrokes per 45 degrees. (16 fires for one revolution)
No because it's a 4 stroke engine so there will be 8 fires per revolution so 45° is right. Correct me if I'm wrong please.
That is correct.
David Ottink yes That is correct. It takes two revolutions to complete the 4-cycle, A 16 cylinder engine would light a plug every 45 degrees.
