    I am just blown away by your knowledge and thorough explanation of the concepts. The entire concept of the power pulses to the back tire are fascinating. I really like the flat plane cranks for the smooth delivery of the power and this would explain why Rossi and Mir are so good at conserving their tires (I4XP) - and also why Dovi keeps burning up his (V4). Excellent video!

    The 990cc era was one of the best era's for MotoGp engines, where the engines had 5 cilinders instead of 4 cylinders. Watched a few races in person in 2005/2006.The most brutal and extraterrestrial sounds. I frequently visit MotoGp races now, but it's not the same anymore. That experience can't be replicated. Anyone who ever witnessed a 990cc GP knows what I'm talking about. You can also hear the difference on video but in real time, you feel it in your veins.

    A 65 degree V4 is shorter in length compared to 90 degree V4. So, it can have more horsepower than a inline 4 and better corner speed compared to a 90 degree V4. RSV4 series are the best sounding production motorcyles also.

      Different V angles suit different rev ranges, other than that only the usual engine specs determine power: bore/stroke, head shape, valves/porting, camshaft, carb/injection setup. And how many balance shafts your given engine needs to drive. This is why engine displacement is the biggest factor in drag racing, not crank type or number of valves etc.

      Inline 4 revs the highest because it is the most balanced 4 cylinder engine configuration with it's superior primary engine balancing quality. Without the use of a balancing shaft, an inline 4 can run at high crankshaft speeds despite having mediocre secondary engine balancing.

    • @joshuarenacia694

  • @fast_odin
    @fast_odin Před 3 lety

    Lemme explain what happens in a Big Bang engine. First of all, no matter what motogp bike you choose, they all slam the rear tire to the ground when they hit the throttle, but that's due to the swingarm, chain and suspension geometry. Thats also the reason of those enormous high-side they do. Now, consideering what you said about de engine pulse sections (wich is correct), we can deduce that having all those as close to each other, acts kinda like if they were in resonance: the second explosion uses the inertia of the firs explosion to multiplicate its actual force, then the third one with the previous two ones, and so on. That traduces to more Engine Torque, wich equals in consequence in just a little bit of extra down push of the swingarm so the tire. And last but not least, those gaps between the pulse sections are good to unstress the tire for a moment and make it grip a little bit for the next pulse section. That, combined with the torque fact, means greater acceleration if we put two same bikes with the same gear ratio etc. But in reality it can be modded as much as seing screming Suzukis going through corners in an higher gear but still accelerate the same but still have more top speed. To conclude, just one more thing. It's interesting what you said about the need of air in the intake in a shorter amount of time. It's true and you were correct, but isn't that much of a concern: consideering that those are a liter bike engine, they suck a little amount of air if you compare it to some big engine cars wich need force induction intakes, not to provide more aire but to provide enough of it. In a motogp bike, or a street bike like so, you have the ram air, wich is as simple as a direct intake wich by third law of Newton, equals in a little bit more pressure in the airbox. With that and a liter bike, you will never run low of air in the intake, there is enough air comming to you at a certain speed. The real concern here, is to make it reach the cylinder without make it go through turns and corners in an airbox etc. That's exactly why they make the ram air through the chassi, and almost direct to the valves. Oh, and the inline4 - v4 thing, they're not better than the other one, the fact here is the final mass of the engine. As you well said, an inline 4, naturally comes as a screaming engine, because it's balanced and perfoms well, but if you wnat to, you can make it big bang, by crossplaneing it. Same but oppossite with the v4: A v4, due the firing order and how the rods are conected to the cranckshaft, make them big bang by nature (more or less depending the degree of aperture of the v, for example: Honda, Ktm: 45º Ducati. 90º). Also if you want to, you can turn it into a screamer, but that's not usually the case, also it,s a little bit harder. What really matters with the shape of the engine, it's the internal components. Without further looking, we have the cracnkshaft, wich is the heavyst moving object in the engine. In an inline 4, it's longer so heavier. In a v4 it's shorter si lighter. That, in combination of the big bang or screamer mode you choose, makes the engine climb rpms from bottom fast as hell (if it's lighter), or use the inertia of the crank to make it climb little bit slower but further in rpms (if it's heavier).
    Glad to see you talking about those interesting things, and happy to help with it.

  • @Drunken_Hamster
    @Drunken_Hamster Před 3 měsíci

    You messed up Ducati's twin-pulse. It's actually a 90-degree V4 with a 70-degree crankshaft creating 90-200-90-340 spacing. Additionally, before 2018, Honda was using the old school "Droner" firing interval with a 90-deg V4 and a 360-deg crank. 90-270-90-270. Droner is an Odd-Pair, Even-Set pulse order engine, whereas Ducati's twin-pulse is an Odd-Pair, Odd-Set pulse order engine.
    These are terms I just made up, but I think they're accurate descriptions of how each engine design spaces pulses. At the same time, a 90-deg V4 with 180-crank and cross-plane I4 is just a fully odd firing "no pattern" engine, and a flat-plane I4 is exactly the opposite, being a completely even "no pattern" engine. But of course, you have the inertial torque thing to worry about, there.
    Personally, I think anything works besides what's been proven NOT to work, which is the flat-plane, even-fire design. I'm also not entirely sold on this "long bang" malarky either. After all, that's a LOT of sudden power to stack up at once, even if it happens less often on a smaller section of the tire. I personally like how the Droner order looks on paper. Odd but even and no inertial torque to worry about, either.
    Clearly, Honda themselves think differently and possibly found something better since they've been on the "long bang" train since their 2018 revision RC213V.

    • @laurensbrantsen
      @laurensbrantsen Před 3 lety +5

      Because of the more complex engineering, the costs to manufacture a v4 are higher compared to an inline-4. For street use, the actual technical advantages of using a v4 engine are less important than in racing where every fraction of a second counts. And with an inline-4 being cheaper to manufacture, it means that the MSRP can be lower. This is probably partly the reason why Ducati's and Aprilia's are more expensive than their Japanese (and even German) counterparts and a bit more "niche" so to speak.

      Maintenance on a V4 is a bit tougher as well so more hours and more costly. That said they don't have the vibrations through the bars like most I4s and have much flatter torque curves so they are more pleasant to ride at a less than 10/10 pace. I don't ride that many miles compared to a lot of sport bike owners so I don't mind a bit more on the maintenance. But can't handle the vibes from most inline motors. I have ridden my Aprilia 5+ hours in a day no issues. Some I4s after 15 minutes my hands are starting to revolt against me because of the vibrations. A lot of people have only ridden I4s so they don't know any different. I've ridden close to 200 motorcycles at this point so I know what I do and don't like.

    great informations. obviously with unified electronics yamaha and suzuki are at disadvantage because they cant tune it to their needs and it seems its now electronics is tuned more for the big bang. before unified electronics yamaha was really strong, suzuki was out because of simonceli, but now they both seems to struggle a lot with power transfer to the ground. ducati is rocket vs yamaha and suzuki. correct me if im wrong.

    The flat plane 4 problem was about feel inb that. At hight revs. The torque to the wheel doesn't respond to the throttle. Its just engine speed and crank inertia.

    I did a quick google regarding the wheelbase of each bike and the numbers I found were all shorter for the V4's (not sure I trust the sources though), Mike, do you have any accurate measurements to share? Great video as always!

      At last someone thinking about things.. the shorter cases of the Suzuki & Yamaha inlines allows for longer swingarms.. short wheelbase creates quicker turn & roll into corners but also creates a wheely happy setup.. there's an ideal wheel base for rider bike combo & class.. Mike's also wrong on his use of the term vibrations both in engine config & effects on tires.. as with the big bang concept that was realised by Yamaha, but in their flat track days with the 650 twin.. Mike's "vibration" theories are all to do with harmonics.. specifically critical mass & harmonic frequencies.. sometimes lighter ISN'T better.. it's best seen when dragster car tires patter & break traction.. bike tires with soft pliable carcases will do the same in how they react to power pulses from the engine.. & length of swingarm & chain significantly affects these harmonics too.. hence how swingarm harmonic balancer a work that attach to the end of a swingarm.. cush drives too can work for & against wheel drive harmonics depending on the rubber densities & volume mass squash effect.. the maths would be horrendous.. note Ducati employing a dynamasist to address harmonic resonances in their gp23 engine with different cylinder bank angles & firing orders.

    Nice one I enjoyed that, v4s and big bangs sound the best

  • @TerryClarkAccordioncrazy

    Thanks I learned something. It's counter intuitive because we might think that evenly spaced power pulses are best, but my own experience with 90 degree V twins tells me otherwise.

    • @rossbrumby1957
      @rossbrumby1957 Před 3 lety

      Other than Ducati, I can't think who else uses 90 deg V twins. Are they single crankpin or a 180 degree twin crankpin?

    • @TerryClarkAccordioncrazy
      @TerryClarkAccordioncrazy Před 3 lety

      @@rossbrumby1957 The Suzuki SV650 is also 90 degree V. They use a common crank pin which allows perfect primary balance but gives uneven firing order.
