One way to look at the electric turbo is that over time we store power in the battery, ideally when the engine is running at a high efficiency, and then we use that stored energy to boost the input when we want more power, all without pulling any power away from the engine at that time. So really this is a battery booster ;-)
Not really, a 'battery booster' would be something that gives your battery a boost of charge. I suspect you were trying to say its a 'battery powered booster' 😉 But I think Hondas term is perfectly accurate and acceptable.
E-charger is only for drivability and power for downsizing . Efficiency is not a target, because there isn't a turbo-generator too. For motorbikes application, is better a bigger V-twin with a direct stratified injection, I think😊
While some may criticize the use of an electric compressor as unnecessary or complicated, it is a huge step forward in improving performance and reducing emissions. Honda has always been known for their innovative spirit, and this V3 engine continues to affirm their position in the automotive industry.
I'm thinking 🤔 on a car with more room. They could use a hybrid turbo that works like a regular turbo. But also has an electric motor for low rpm boost that is coupled to the turbo shaft by a small magnetic electric clutch.
On the configuration I showedd you got two at tdc and one at bdc. Secondary points up both at bdc and tdc so it's worse than an inline three but secondary isn't really too important on bikes as the reciprocating masses are small.
@@d4a That V5....The mesh on the intakes, was that all "intake filter" these had ? Looked like it was only able to filter birds and medium to large size rocks...
Fun fact: When i saw the honda v3 for the first time, I was immediately anticipating that I needed to wait for your video before getting all the info I need. And of course, that was correct. Thank you for amazing content, as always!
Incidentally it is an electrically powered *supercharger* . The Germans call it a Kompressor but the English word is supercharger. During WW2 there was a huge competition between engines with superchargers and turbochargers, or even both, with one US aircraft being basically a frame wrapped around a huge turbocharger installation. Turbochargers didn't give as much benefit as hoped for because some thrust was being generated by aiming engine exhausts backwards, and the turbocharger absorbs energy from the exhaust. One interesting approach is to have an electric supercharger and a turbocharger driving an auxiliary generator, with a battery providing power for rapid spinup. I'm very willing to be corrected, but I believe this has only been tried on ships.
Audi used a 48V electrical supercharger to assist the bi/twin turbo 4 litre V8 diesel engine. Recently discontinued, used in: SQ7 SQ8 Porsche Cayenne Bentley Bentayga
It seems like a regular supercharger would be a better more reliable option if they want it to be mounted high and take up less space just have it attached to one of the cams you can gear it back to crank speeds or faster and still be smaller than that electric motor
@@MikeHoncho0811 But the electrical compressor isn't connected to the engine revs, so can adjust boost levels independently from them, enabling the flatter torque curve. The supercharger approach provides a constant boost over the whole rev range, with this linked in boost level to the rpm. The ideal setup would be a turbocharger to provide constant cruising boost and energy recovery, with an electrical compressor providing boost at low revs and to fill gaps until the turbo spools up. That's the setup in my Audi S4 TDI combined with a 48V MLEV system.
Then what would happen if we had a centrifugal vacuum pump to evacuate the air from the cylinder shafted to an electric motor that was shafted to a compressor and a compressor wheel pushing air into the engine
Thank you for consistently posting interesting and informative content. Having a teacher with a good sense of humor always makes it easier for me to pay attention. Happy Christmas and Merry New Year!
Check out the upcoming BMW F450GS Concept's engine 125º crankshaft. Wonder how this layout will be different pros and cons compare to other 180º and 270º mainstream layout, hopefully you could do an explanation for this, look forward to it.
This design is about meeting Euro6 emissions. That means lower piston circumference and peak power at lower rpm, because valve overlap is no longer possible. The assumption is electric power is coming from a larger alternator, but it may be coming from an energy harvesting motor in the front wheel.
Brilliant explanations as usual. The naked roadster V3 Honda will be my first Honda and force induction motorcycle. This is shaping up to be the most interesting motorcycle of this decade
Sounds like it will also have the most advanced electrical system of any motorcycle to date too. Possibly a 2nd high performance lithium ion battery just to run the supercharger?
@@volvo09 It will only need one, but it will probably be a custom Honda specific battery. Most lithium batteries you buy for motorcycles, if you look inside of one the battery takes up perhaps 1/6th of the volume of the battery. There is a lot of air space in there. That's because the battery needs to have the same form factor to swap in, but a traditional motorcycle doesn't need a huge electrical capacity.
@@brunocarmona4958 If you look at Honda's images in the video, there doesn't appear to be an external alternator and the generator side of the engine looks about the same size you would expect from a 750-800cc motorcycle. My thought is that Honda will be using a battery to get full power out of the e-charger. This of course means that the bike will only be able to produce it's maximum power for a short amount of time. But given this is a consumer level production motorcycle, unless you are planning on extended max speed rides down the autobahn, it's going to be enough for most riders.
The thing I like is that the parasitic load is spread out over time, while the battery alone is running the eCharger. But the alternator still doesn't have to be ginormous. Only large enough for a practical recovery. This is like a series hybrid. Batteries get you on the parkway, and alternator has time to recoup the loss as you noodle along. Good engineering principle. Battery acts like a buffer between the electrical demand and the restoration of power over time.
They’ve made a V3 before, so it was only a matter of time before they would make another one, this time a 4-stroke too! I can’t wait to hear how it sounds, or better yet. Which bike it’s going in.
For quite a long time I wondered why engine designers did not incorporate an electric motor on top of the turbocharger. This would alleviate the turbocharger’s main disadvantage - turbo lag. Great explanation of this technology.
You would think there would be more hybrid electric assisted turbos out there, it's a pretty simple concept of an electric motor with a one way clutch when exhaust takes over the motor disengages. Best of both worlds zero lag with high rpm spool, and where turbo lag isn't an issue the turbine could be sized larger reducing power robbing back pressure. Or even an engine driven belt assisted turbo, using the same concept... Practically everything has been tried by now so These ideas are not original I'm sure and already existing somewhere in some OEM R&D facility but still odd there's not readily seen, well at least by myself, but even tho being more complex they seem like they would be a win win.
Or you could just spin the wheels with the electric motor assist. Or spend the extra money on making it rev higher. Or on displacement. Anyway its pretty niche where using the kilowatts to spin a turbine is a good use vs just using directly for powering the vehicle forward
I pay for RUclips Premium, and I follow a lot of different channels. But this channel alone is worth the price of admission. Quickly becoming one of my favorites. 👌💯
Another point about not having to run continuously is that for "short bursts of boost" it can draw some (half+?) energy from the battery, whereas if continuous the alternator needs to have at least the same power rating as the compressor motor, thus allowing for a smaller alternator. I would not be surprised if it had a 24 or 36 volt motor/battery/alternator system and a solid state voltage reducer to charge the 12 volt battery.
When i saw that i was thinking about the f1 turbine to generate electricity over exhaust. I wonder what kind of different turbine designes you could take to power an generator with it. Since you could theoretically manage generator output via electronics. So you could use an pretty freeflow turbine which is not that restrictive but still generating electricity to recuperate some of the waste.
@@nicoleibundgut534 it sorta has to be restrictive to get power out of it. Like you can lose power without making it from restrictions, but to spin it has to be a restriction. You could have a large buffer though.
@@lassikinnunen Would further complicate stuff but you could use exhaust flaps to recuperate energie in cruise situations. When batterys are fully charged you could even directly use the energie to power electric motors. More a case for hybrid cars then a bike tho.
Thank you, glad you liked it. It's a turbine, I'm just showing it to demonstrate what's unnecessary...sort of. Maybe wasn't the best idea when I think of it now.
With a turbocharger the exhaust manifold between the engine and turbo may be more complicated, but, since the turbo removes a lot of energy from the exhaust gases, the silencing section of the exhaust can be simpler and more compact.
I'd love to see the electric supercharger system used with a sorta hybrid-esque powertrain, like, add ebike-style hub motors to the front and rear to use as dynamic brakes to charge an independent, higher-voltage battery bank (or even supercapacitors) for the blower whenever you slow down. Effectively multiplies your energy input (via regen braking) into gaining MUCH more output power by using it to supercharge a combustion engine instead of just putting it back into the electric motors, plus for continuous boost it can sorta function as a traditional supercharger by siphoning power off the driveline and putting it into the supercharger, since modern brushless motors and centrifugal superchargers have efficiency on par with an oldschool straight-lobe Roots blower when used together.
wait a minute. compared to the porsche version - that is an electric turbo cus it does have a turbine and does rely on the exhaust gases eventually? but porsche uses the electric motor up at the start so that compression can be peak before exhaust peaks, ii.e. to reduce turbo lag? am i wrong? will this honda electric compressor work throughout the rev cycle or will its 5 psi just be used to spool up?
Brilliant as usual. Have you done a simulation about electrical requirements for the electric super charger? In a Italian motorcycle magazine the engineer had some doubts about that. ( lot of electrical power needed to spin the booster)
I actually made project in my collage on combination of turbocharger and supercharger. Where supercharger was electric. It was 4 years ago . I was inspired from a rally car which used both methods of forced induction. The car had supercharger which used engine'd power.
One of my friends in high school told everyone he drove a "V5" (when it was an I5) and everyone called him an idiot. Who knew he was 20 years ahead of the game with odd numbers of cylinders.
The first mass-production straight-five passenger car engine was the 1974 (Fifty years ago) Mercedes-Benz OM617, for some military/commercial trucks even before that.
One not mentioned advantage of a turbo is the pressure/energy contained in the exhaust gas at the end of the power stroke (@BDC) when the exhaust valves first open is recovered for the short time before the piston on the exhaust stroke has to feed power to the turbo.
In the turbo the part of the energy that is more than what it consumes is you could call free energy. Or boost energy. Because it raises the over all efficiency of the engine.
Thats only true for diesels to a certain extent. Now if you're just talking efficiency in terms of an emission test cycle then sure it can help vs. An engine of similar max power without a turbo, but just for kilowatts out of same amount of gasoline it doesn't help.
@@lassikinnunen Yes, it does! Turbo increases over all efficiency, especially on high loads. Because the engine is able to maintain higher pressure towards the middle of the stroke, where the leverage is greater. Turbo gives you higher efficiency and more power at the same time!!!!
Great content as we are used to ❤ In the animation of the compressor I am a bit puzzled by the flow of the air. IMO the air gets sucked in at the center. I may be wrong of course 😕
@@d4a hmm... so let's get good old Honda CB500 alongside with Fiat 126p and combine the sound together... kinda weird😆, maybe it would be close to T-plane inline-3 of Triumph?
Having the power be variable depending upon the length of time the compressor runs will provide a unique driving experience. It might be interesting and sort of fun but practical? I'd hope it can stay on boost for 60 seconds but I'm thinking more like 10 seconds. Then how long do you have to wait till it can spool up again. The thing there is you don't know if your going to get the boost when you crack the throttle. I'm thinking, just weird. I loved the whole thing the first time I saw it but I think it's the answer to a question nobody asked.
Honda is so back. This will be the spiritual sucessor to the Honda CX500 and CX650 turbo bikes. Whatever this bike is, I'll probably buy it for a companion to my CX650t
So, to get the extra mass on the rear cylinder, could it just be made larger in bore? This would make for uneven power pulses similar to the big bang motors. Might be good for traction.
Amazing video! Thanks. My first thought was that the center piston would have a larger bore but the same stroke as the other Pistons. If the bore was 1.41 times the other two then it would have twice the area and twice the displacement. So it would kind of be like a V4 but with a shorter crankshaft and now narrower horizontal block. Which is what we want. But then there's the 75° angle. This would screw everything up that I was thinking about. Do we actually know that the bore of the third piston is the same as the other two? If it was larger it would be a cheaper way of getting more displacement without adding any significant mass to the whole engine. Love your videos
Thanks for the explanation. After owning some of Honda's V4 engines and doing maintenance on them, I'll pass on this V3. If Honda's engineers want to get fancy, I would rather see them apply GDI to a 270 deg inline twin with some fancy valve timing like Hyundai's VVT that can vary timing and duration.
While the turbo charger creates backpressure and therefore power draw from the engine, the additional electrical power from the alternator also creates additional power draw. Which would explain, why they designed it as a temporary boost, basically harnessing power that would go to charging the batteries or be wasted in resitors, as opposed to a constant power draw, because it probably requires too much power to be viable more viable than a traditional turbocharger.

My wifi is horrible and I can’t see the video but if it has something to do with Honda’s V3 im gonna lose it
In the turbo the part of the energy that is more than what it consumes is you could call free energy.
Or boost energy.
Because it raises the over all efficiency of the engine.
Thats only true for diesels to a certain extent.
Now if you're just talking efficiency in terms of an emission test cycle then sure it can help vs. An engine of similar max power without a turbo, but just for kilowatts out of same amount of gasoline it doesn't help.
@@lassikinnunen Yes, it does! Turbo increases over all efficiency, especially on high loads.
Because the engine is able to maintain higher pressure towards the middle of the stroke, where the leverage is greater. Turbo gives you higher efficiency and more power at the same time!!!!
7:05 Don't emissions go proportionally to boost if you maintain the same stoichiometry of air to fuel?
Great content as we are used to ❤
In the animation of the compressor I am a bit puzzled by the flow of the air. IMO the air gets sucked in at the center. I may be wrong of course 😕
Thanks again for your awesome work! I appreciate it very much (also the spicy comment on ignoring environmental impact😂)
I got traumatized by that shitty AI voiceover, im glad i can use the original one
What AI voiceover?
Get a grip of your life AI is the way forward whether you like it or not. You have no choice but to go with the flow or not be in the flow pathetic
Yeah the auto-translated audio tracks are quite lifeless
@@d4a theyre talking about the audio tracks, they are sometimes auto enabled
How to disable it from a mobile browser? The only way I see is to use the desktop mode, but is not very simple.
great video.
Great video as always :) thanks!
Any predictions on sound?
It's sort of switching between a 360 and 180 inline twin sound, might be interesting
@@d4a hmm... so let's get good old Honda CB500 alongside with Fiat 126p and combine the sound together... kinda weird😆, maybe it would be close to T-plane inline-3 of Triumph?
Some companies call them electric superchargers
Having the power be variable depending upon the length of time the compressor runs will provide a unique driving experience. It might be interesting and sort of fun but practical? I'd hope it can stay on boost for 60 seconds but I'm thinking more like 10 seconds. Then how long do you have to wait till it can spool up again. The thing there is you don't know if your going to get the boost when you crack the throttle. I'm thinking, just weird. I loved the whole thing the first time I saw it but I think it's the answer to a question nobody asked.
Honda is so back. This will be the spiritual sucessor to the Honda CX500 and CX650 turbo bikes. Whatever this bike is, I'll probably buy it for a companion to my CX650t
So, to get the extra mass on the rear cylinder, could it just be made larger in bore? This would make for uneven power pulses similar to the big bang motors. Might be good for traction.
Vtec + E-comp might be nice idea. Good sound also
Amazing video! Thanks. My first thought was that the center piston would have a larger bore but the same stroke as the other Pistons. If the bore was 1.41 times the other two then it would have twice the area and twice the displacement. So it would kind of be like a V4 but with a shorter crankshaft and now narrower horizontal block. Which is what we want.
But then there's the 75° angle. This would screw everything up that I was thinking about.
Do we actually know that the bore of the third piston is the same as the other two? If it was larger it would be a cheaper way of getting more displacement without adding any significant mass to the whole engine.
Love your videos
Very interesting! Thanks.
I wonder if placing a cvt between the motor and the compressor wheel could help keep the motor under less load
Dude I learned more from your videos than from the lectures in the university…. Keep going 💪
Rotary vane engine plz ?
Thanks for the explanation. After owning some of Honda's V4 engines and doing maintenance on them, I'll pass on this V3. If Honda's engineers want to get fancy, I would rather see them apply GDI to a 270 deg inline twin with some fancy valve timing like Hyundai's VVT that can vary timing and duration.
While the turbo charger creates backpressure and therefore power draw from the engine, the additional electrical power from the alternator also creates additional power draw. Which would explain, why they designed it as a temporary boost, basically harnessing power that would go to charging the batteries or be wasted in resitors, as opposed to a constant power draw, because it probably requires too much power to be viable more viable than a traditional turbocharger.
