2009 Yamaha R1 Engine Explained

[marlonalejo]

y en español..??? ajajjaajj..



[slklmk]

actually it got stolen from american muscle v8 ... and such

[falaqdad15]

V8 (except ferrari) crank but with one cylinder bank

[L1LD0G]

I don't know what he said but it sounded legit

[2xchrome]

Boring

[billysull]

It's hardly revolutionary...it's exactly the same principle that Triumph used with the release of the 750 tripe Trident T150 in 1968!! The only difference being that this crankshaft has four pins. Not only does the design equalise inertial torque, it also largely eliminates vibration....nice of the Japanese to mention the heritage of "their idea"!!

[rr92890]

ohhh NOW I get it.... -___-

[VituMV]

just how bad do you not want to have lunch with the person responsible for this engine setup... great results tho

[TheCrashOf29]

mmmmmmmmmmmmmmm...............­.marketing.

[makeminealarge1]

mmmmmmnow where can i steal one, cause i doubt i could afford one, lol

[1970Swordfish]

You can do like me... Lot's of debt with a Bank next to you... LOL

[seang15243]

I want that same technology in an automobile inline four

[ukcog]

what a load of old bollocks! Bet its quick though. Wish I had one in my Mini

[1337ASM]

R1 minis ftw :P

[Jac0lius]

Good Video!!

[blk600cc]

In english: "It's fast as fuck!"

I want one!

[RX7T51]

NICE ...NUMBER 1 .

[mApLeLeAfs4EVA]

i fucking love that bike!!!!!

[1970Swordfish]

I hope it's GOOD bike, I just bought one 2009 model (new bike, not riden)

[Kaymo172]

Quantifying a Wankel engines capacity and comparinging it to a piston engine has always been dubious at best

[cartmansmyson]

Best 2009 1000cc Hands down. Please don't compare to a Ducati thats 20-30k more Best Bang for your buck in my opinion.

[patrickortiz420]

if suzuki didnt make the gsx-r look like such crap for 09 i wouldnt be watchin this :(

[PheloniusRM]

Notice how it sounds like a Desmosedici? That's because a crossplane inline 4 is the same as a V4. How creative of you Yamaha. Unfortunately it still has the detriment of being twice as a wide as a V4 so it handles worse. Combustion torque vs inertial torque? That means it feels like a V twin. Good job Yamaha, you successfully reinvented the Ducati wheel. Let me know how next year's GP turns out when everyone is on the same tires...

[Futurensen]

Yeah whatever..Go buy a ducati then..

[Ganso1]

The Ducati's sound is more about Desmodromic valve configuration than piston's.

I liked the new sound a lot, it's the same that we hear on motogp. Of course the old 4cil inline was great, but talking about performance, the new piston config just owns from zero to the red rpm line... Probably my next bike.

[Futurensen]

I agree..Is just that some ppl hate yamaha because of its racing results..Call it jelus or smthng like that witch make persons like Phelonium saying stupid things like that..Personally because of my brother,i've lived with 3 R1's till now and the one simple fact i see is that every new model is better than the old one..And ever better than the rest bikes eg suzuki GSX-R or kawasaki ZX10..

[chichipukaka]

I cant understand one thing, this crossplane tech. is against the SBK rules right? So how is Yam gonna race?? Or is it allowed now???

[LokiDWolf]

So, why is there a conversation about car engines and not moto engines? lol

[rhand18]

I know the R-1 is and always has been a single bank inline-4 just as my Honda 599 and Kawasaki zx-14 were. And between all my riding friends who I often switch bikes with I have ridden most makes and models including a 2007 Yamaha R1 (so don't even try that 15,000 rpm without a whisper through the chassis on me). And I know you don't need another bank of cylinders to balance and engine, just counterweights and/or balancers. And seeing as most road car tech is WAY behind bikes I wouldn't compare.

[rhand18]

Actually a crossplane style V-8 does have an uneven firing interval in each seperate bank of cylinders (there are many diagrams to look at online and I am in fact looking at one for a non-HO ford 302 right now). However once again, after you add in the other cylinder bank the engine becomes even firing. Since the R1 has no extra bank of cylinders it remains uneven. However this still supports the original point I was making that Yamaha are using a crossplane v-8 style crank adapted to an I-4.

[rhand18]

Crossplane V8 engines does in fact have uneven firing patterns within each cylinder bank, but an even firing pattern over all due to the other bank of cylinders and counterweighted crankshaft balancing it all out. The new R1 does not have an extra bank of cylinders to balance out with so they are using a new type of balancer shaft to simulate the balancing effect the extra cylinder bank would normally provide.

[rhand18]

You do realize that this type of crankshaft has been used in every American and many european V-8's since it was developed in 1915 by Cadillac and Peerless, right? Since a V-8 is at its most basic level 2 I-4's grafted onto a common crankshaft you could usually solve the problems of each engine by using technological advancements from the other (inline-4 balance shafts for euro style flat plane V-8 engines for instance) and now 94 years later using american v-8 tech to solve inline-4 problems.

[viasevenvai]

excellent explanation of why it was done. saying others will adapt this same concept is like saying everyone will put 5 intake valves on each cylinder like Yamaha too, there are good and bad things about the technologies...........althoug­h i don't know what is bad about the new yamaha crank....

[viasevenvai]

meant 3 intake valves, 5 total.

[MikeJS57]

Would Yamaha be able to patent this crankshaft arrangement, is it more likely that they could licence it or is neither the case ?

[ednut69]

i thought this was common technology on nearly every motor now, bikes are just picking it up?

[djtech666]

this is an awesome innovation in commercial motocycles engines..the other bike manufacturer will do the same with the new models.

[BenBen5501]

Has this ever been applied to inline 4 auto engines or even the straight six's?

[anothercbrowner]

pfft if they applied the stuff from motorbikes on cars you would get similar hp figures :P

a liter bike makes about 180 hp @ the crank, now imagine a 2 liter car making 340 natural aspirated horses *_*

[m1yamaha]

and rev the 2 liter to 13+

[pkforbes87]

You're right that a 2 liter 340 hp engine is possible, but the drivetrain components required to get that power to the ground do not exist.

Your hypothetical 2 liter 340 hp engine produces less than 50% of it's horsepower under 10k RPM, but there is no clutch or torque converter that can withstand engaging at those speeds. The clutches found in modern sport bikes could withstand the high RPM operation, but are not designed to be used in a 2000lb vehicle.

[anothercbrowner]

tell that to the guys who build the f1 cars

[pkforbes87]

F1 clutch design is unique, and works very well for approximately 400 miles after which it is replaced

A production car uses a dry single plate clutch. The single clutch plate can not handle the high RPM engagement of a 2.4L V8 so the F1s use a multiplate

(Most) production motorcycle use a wet multiplate clutch. The wet clutch is used to prevent rapid damage to the multiplate design during high RPM engagement, but does not effeciently accelerate a 1000lb+ car.

Thus the dry multiplate design

[gslwales]

and imagine multiplying 180 by 2 and getting 340 :). Honda S2000s get bout 240 bhp from a 2 litre na engine, and thats the best in any production car in the world, so i cant imagine it lol. good maths though

[Ad4l4xy]

Actually its the Type R motor with better Horsepewer per liter at 1.8.

And 180 times 2 is 360 not 340.

[gslwales]

Well never, thats why i said imagine it, ie whoever said 340 was wrong. And i thinks you'll find an s2000 is 2 litre

[Ad4l4xy]

Nar really? Also did you know the S2000 is also a 2.2 after 2003 model year? But i bet you already knew that.

What i was saying was that The S2000 DOES NOT HAVE THE BEST HORSEPOWER to displacement. The B18C5 does. The Integra Type R motor does.

And if you check your post it was you who said 340.

[jsmorel86]

so what your saying is that a integra type-r b18c5 195bhp 1.8 liter engine has more horsepower per liter than the ap1 s2000's f20c which has 240bhp from 2.0 liters of displacement? i think you and your friends math are a little off. ill try to help you out. the f20c produces 120bhp per liter and the b18c5 produces 108bhp per liter. so the f20c clearly has higher hp per liter. both are outstanding engines in completely different platforms so ya....there it is

[Ad4l4xy]

To bad in all reality the Wankel Motor still wins for all motor applications with a Guaranteed 196 horsepower per liter. Non turbo.

What your forgetting in all your math is tuning. For the cam profiles that the f20 uses that b18c5 still makes more power for a less radical cam profile. Its still the B18C5 sorry.

[jsmorel86]

kaymo172 is right about the wankel always a hot topic. lol. so now your talking cam profiles and not displacement like earlier? tuning? were talking stock for stock. hp per liter is based on displacement vs bhp. im not sure where you think cam tuning is coming into play with factory stock engine horsepower. who cares what cam profile they use. the fact is they got a certain amount of horsepower out of a certain displacement. i hope you at least know the wankel doesnt have cams.

[jsmorel86]

i think your just grasping for something because you dont want to admit your wrong. or maybe you really dont quite understand math and or how engines work. but id like to think that you do. and yes madzas claimed 238bhp rx8 would be 183hp per liter considering the 1.3l engine i never said the s2000 has the most horsepower per liter ever of all time. i was simply using it as an example to prove you were mistaken about the b18 vs the f20

[JeffroGymnast]

there's no need to do any of this to straight six's... they are symmetrical in their strokes. meaning that when one cylinder is at a certain stage in the cycle, another cylinder is at the exact opposite stage. so it has a pretty constant torque.
