RC211V model: amzn.to/3PSE9Yv
In 2002 Honda introduced the RC211V motorcycle to MotoGP, the highest level of motorcycle racing in the world. The bike was a response to the chaning rules of Moto GP and replaced Honda's previous contender, the iconic two stroke NSR500.
Now the big deal about the new bike is that it's engine was something that no one had ever seen before, a V5. I mean over the decades we have been conditioned into thinking that a V engine must have an even number of cylinders, V2, V4, V6, V8, V10, V12. And Logically it makas sense....we have two banks of cylinders and both banks have the same number of cylinders which means that neither bank is generating more force than the other bank leading to a well balanced engine.
The general public was so puzzled by the V5 engine, which has 3 cylinders in one bank and 2 cylinders in the other that soon rumors spread claiming that the bank with two cylinders had larger bores and larger pistons to restore balance. This of course wasn't the case, all pistons and bores are of the same size. But even to this day, many people believe that a V5 engine is impossible and would self-destruct in operation. However Honda proved this wasn't the case, not only did the engine NOT self-destruct, it revved continuously and reliably to 14.000 rpm, and it did it it's job so well that it helped Honda win three rider and four constructor world championships. In fact the bike won 48 out of 82 races, it won more than half of all the races it entered, which is an extremely impressive statistic for MotoGP and even more impressive for an engine that should self-destruct according to layman logic.
How do you make a V5 work? Well the answer is pretty simple....you make it work by building an unbalanced V4 and then using the extra piston to balance things out.
So how do you unbalance a V4? Well that's easy, you loose the 90 degree angle between the banks that allows the counterweights to keep things balanced. This why Honda gave their V5 an angle of 75.5 degrees between the two banks. The added bonus of this is that it makes the engine even more compact and allows the wheelbase of the motorcycle to be shorter which improves handling response.
But why exactly 75.5 degrees? Why not 80 or 70 or whatever else. Well the answer to that is that 75.5 is the point at which the piston of an internal combustion engine is at or near it's maximum velocity.
And why is this important? Well to understand that we have to observe the V5 engine in action. As you can see Honda's V5 is essentially a V4 with zero degrees offset between the two common crank pins, and an unpaired piston on a single crank pin between the two piston pairs. As we know the angle between the two banks is 75.5 degrees and the crank pin of the unpaired piston is offset by 104.5 degrees from the center-line of bank 1 when the engine is in this position. These angles result in the forces created by the engine canceling each other out. See video for actual detailed explanation with graphics.
One more final side-point just in case someone is wondering. No, the engine called V5 by Volkswagen does not work like the one we just discussed. As far as I know the V5 in Honda's RC211V is the only one of it's kind and it was never mass produced, it was made only to compete in Moto GP. What Volkswagen calls V5 isn't really a V5, a much more appropriate name for it would be VR5, in the same fashion as their VR6 engine. Honda's V5 is a true V engine with two cylinder heads and two sets of camshafts, cam gears, etc. Volkswagen V5 is just like a VR6 but with one cylinder less, meaning that we have only I believe only 15 degrees between the banks, one cylinder head, one set of cams etc. And just like the VR6 has balance very similar to an inline 6, so too does VW's „V5“ have very similar balance to an inline 5

The only V5 automobile engine to reach production was the 2.3 L (140 cu in) "VR5" engine manufactured by Volkswagen from 1997 to 2006. Based on Volkswagen's VR6 engine, the VR5 was a narrow-angle engine with staggered cylinders (three cylinders on one bank and two on the other) sharing a single cylinder head.[3] As per the VR6 engine, the angle between the banks was 15 degrees. Initial versions used 2 valves per cylinder, however, an update in 2000 resulted in a total of 4 valves per cylinder and the addition of variable valve timing.

@@MR_IC i know my answer won't be very detail but. All of those engines comes from Toyota A series engine. 4A-GE is the normal engine used in corolla with many variations including the 20V black top. 7A-GE is a mix of 7A-FE bottom (the block and crank usually) with 4A-GE head (head and piston). I believe they do this because 4A-GE head can deliver more air and fuel compared to 7A-FE head. This result in a 1.8L engine with exceptional performance on bottom and high rpm. The highest number of A series engine is 8A. 9A-GE is a combination of 7A-FE, 4A-GE and some parts from 1ZZ or 2ZZ engine. Hence why it is not very popular, although it is much more powerful and on paper it can output power and torque close to a K20A from FD2R. 7A-GE and 9A-GE are not official from Toyota, both of them are made by consumers or tuners.

correct. Honda always coming up with crazy ways to take advantage of rules. Honda wanted to make a V8 4 stroke to compete with 2 strokes of the same displacement to avoid giving in to making a two stroke (kind of like how they made a 6 cylinder 20,000 rpm 250 cc in the 60s, Honda had up to that point in the early 80s never made a 2 stroke roadracer) so they came up with an oval piston v4 since 8 cyl weren't allowed and oval piston allowed the valve area more equal to that of an equivalent 8 cyl. It had competitive power but reliability issues and so they finally gave in and made a 2 stroke and won a title with their first 2 stroke 500 cc RC.

This is a variation of the trick Honda did with their 52 degree vee twin engines. The crankpins are offset 76 degrees. (76/2)+52= 90 degrees. They have a 232 degree firing order but emulate the balance of a 90 degree vee.

I think so too, from what i understand the same trick can be used on any odd cylinder engine. The downside is the increased cost of needing an odd and even cylinder head, rather than casting one head twice as many times. That is offset by not needing balance gears. But if a manufacturer already had a related v6 and a v8 on their sales floors. they might be able to reuse a head from each without increasing development cost.

0:49 reading about this engine years ago, I read that the rumors of the 2-cyl bank, thought to be larger in displacement, were designed to have a peak torque RPM slightly lower than the the 3-cyl bank. The 3-cyl bank was thought to have a peak torque maybe 1000 rpm higher. This was thought to give the bike a wider range of peak torque (all high up, as its a racing bike after all). Basically, the thought was it could maintain a wider powerband than a 4-cyl, while still having a higher RPM. Of course this turned out to just be a rumor... but still, an interesting concept.

The V5 took advantage of the rules at the time that gave the same minimum weight as a V4, and at the time a larger amount of fuel was allowed for all sizes (26L or 24L, can't recall). This allowed the thirstier but more powerful V5 to be so competitive. As the max fuel load was progressively lowered it made it less advantageous, although Hayden winning the championship in its final year showed how good the basic bike was at that point. Also don't discredit the tire rules at the time, Michelin would make special tires per Rossi's liking (and a few other riders) and actually fly them to the track between Friday practice and Sunday race. A big advantage for Repsol Honda that was banned later in the decade. Bridgestone was good at some tracks and terrible at others, any rider on 'stones had little chance at the title.

260 hp from 990 cc....sweet Jesus. I would put 2 together. Flip the second ending so the piston per side is the same. 540hp for 2000 cc. Under 500 lbs. Then turbo it...900hp...Mic drop.

I think they changed the firing order for the final version, hence the crazy exhaust, it became a big bang engine

Fantastic and interesting explanation for this V5. Honda has always been the best at studying misalignments of V- engine connecting rods to eliminate vibrations. See the Transalp- Africa Twin and many other models with V 52° with connecting rods staggered at 72°.

Fantastic video, as usual. Next would like to know more about combustion chamber design and intake valve its size, timing, lift etc and how all these factors does affect on engine torque development. Along with it, What's swirl and tumble and their significance. Everything related to it plz try to include and explain it.

@kimpatz2189 Жыл бұрын

For intake valve size... NA engine has a bigger valve to maximize vacuum along with a swirl system to mix the air fuel properly. With a higher valve lift, you can increase entry/exit size further reducing load during vacuum. The exhaust valve can be small as the gas is being positively pushed out by the returning piston. Combustion chamber designs can be designed for non interference or bigger/smaller compression ratio and proper flame propagation. Theres also a different combustion chamber for diesels. The other one that uses indirect injection has a small swirl chamber that tries to mix injected diesel with air. It has mostly lower noise levels than the direct injection but it can't beat modern commonrail direct injection that injects multiple times to emulate swirl while the piston climbs up during compression.

great video as always, i had no problem understanding this and enjoy these types of videos and have worked with tons of engineers and have technical/mechanical background, lines been good, i love these odd spec engines, i could see the Ducati engineers laughing at Honda, they're an arrogant bunch of nuts and Honda said simply hold my beer and went to work and built this awesome engine and watched Ducati pick their jaws up off the floor, I just love it Like when the V4 car engine was built by Ford, I don't know if they were the inventors of it, they used back in the day and was fairly successful and reliable for smaller lightweight vehicles and still see a Saab running around with one in it and its pretty smooth, like an inline 5 CYL Audi/VW used them and Volvo used them when they brought out the 850 series cars cars in 1992 and here in Canada in 1994 and remember driving a base 4DR with a 5 spa manual and that thing ripped for a new model car and got amazing fuel economy, 1st customer said as good as 6.85/7.3 litres/100kms that was really good for that year in the 90's for a big car for Volvo and the natural intake sound was awesome, in 2000 when then used VVT on both intake and exhaust, the V70 N/A 5 speed auto would get almost 1000kms to a tank of petrol, great cars, and great video 👍

That Ford V4 that Saab used was originally designed in the US for a small car called the Cardinal that was cancelled before production. Ford built the Falcon instead, but the engine was used by Ford in Germany in the Taunus and others. It was not, however, a 90-degree vee but 60-degree with a four-throw crank, so it did not have perfect primary balance. It relied on a balance shaft. It was built in capacities ranging from 1.2 to 1.7 litres and fitted to a range of vehicles. Most contemporary reviews found it pretty unimpressive. Ford UK repeated the error with the Essex V4s of 1.7/2.0l (Transit van, which was so boomy that the tradies did not notice the engine vibrations) and matching 3.0l V6 for the Zodiac and then the Capri. For all its deficiencies, some of the V6s lasted long enough for owners to replace the awful V8s in their Triumph Stags with Essex V6 that came either from rusted Zodiacs or crashed Capris.

@Blockbuster2033 Жыл бұрын

What an amazing video. I've been looking for how this engine works for ages. So balance wise this is pretty genious, because it's like a v4, but with a narrower angle and without a rocking couple. So the primary balance is absolutely perfect. However, you didn't really touch on secondary balance. Does it also have perfect secondary balance because of that odd 75,5° bank angle?

@d4a Жыл бұрын

Yes, that's a very important observation, because the rods are stacked the way they are there's no rocking couple. Secondary is very close to v4 but I think it's only slightly worse in terms of secondary balance than a v4, probably irrelevant. We have two at TDC, so that's two forces up, two at maximum velocity, so that's two forces down, and the odd cylinder a bit past max velocity so that's another force down-ish.... So not two up two down like the v4. The v angle is different too so they again don't fully cancel out, just like in the v4, but they're also not perpendicular to each other, which should work a bit in favor of the v5. But all of this is hair splitting, the secondary balance is smallish anyway l, especially on a 990cc thing with tiny pistons (tinnier than a v4 mind you, maybe they're the same overall for secondary) and it's overall miles ahead of a flat plane inline 4.

@timothybayliss6680 Жыл бұрын

I think the crank pin arrangement gives perfect secondary balance. The crankpins are mirrored on the crank with the outer cylinders on the same bank. There also will not be any rocking motion from this either.

@Blockbuster2033 Жыл бұрын

@@d4a Okay that makes sense. So overall the V5 is a pretty cool engine, but it's pretty expensive I guess. You can't use the same heads or even head covers for both banks, they are all unique. So it's fine for a race engine, but unfortunately we'll likely never see one for the street.
