Electric Turbo

Interested to see this:

The use of a 48V system also allows engineers to fit on an electric auxiliary turbocharger (eZV)  that could spin up to 70,000rpm within 0.3 seconds to deliver an immediate throttle response and zero lag.

and how long will it be before we start tearing out our exhaust gas energy turbines and installing a 48v electric one?  It could be a game changer.

I remember reading something about an Audi (that's already in production) using a one - but to spool up a conventional large turbo; I think it's a great idea and good approach to use both technologies together until electric just takes over replacing the entire power plant.

This will be a version of the formula 1 hybrid technology. Turbo is still a turbo but uses an electric motor to assist. And it sounds like effectively a generator/motor harvesting electricity and deploying it when required

If you havent already, check out formula 1's V6 hybrid engines

I'm actually working on an engine equipped with one. The engine is still being installed in the engine bench as of now. We won't test the electric turbocharger before long.

These turbos need to be cooled via the engine coolant or via a low temperature circuit, and with the power cables, the plumbing etc... and the fact that they're small unit for now only aimed at spooling small turbo they're still very far from being properly sized for our kind of engine/usage.

But some manufacturers are working on 12v variant of these babies, you just need big ass wires to feed them. And we still need a control unit or an aftermarket ECU which can control them, an heavy battery to take the shot when the turbo kicks in and a powerful alternator.

Way too much modifications for now to be worthwhile but 10 years from now who knows ?

I got 3.8psi out of a 12V system running on a RB25det engine with a electric turbo that I designed for a Chinese company in 2011. There are way better motors today I think I can get it to make around 7psi if I'm doing it all over again this year. Boost was instant spinning up a T04Z compressor once activated. I guess it can be attached to a turbine shaft to make it hybrid. Just don't know whats the reliability of the electric motor on long run.

super keen to know how you go with the next round of testing....  hope you test it on the torque black hole- rb20det :-)

Cheers

      PRP RB26 cast block + head prototype running

      By GTSBoy · Posted

      Well, yeah, the RB26 is definitely that far off the mark. From a pure technology point of view it is closer to the engines of the 60s than it is to the engines of the last 10 years. There is absolutely nothing special about an RB26 that wasn't present in engines going all the way back to the 60s, except probably the four valve head. The bottom end is just bog standard Japanese stuff. The head is nothing special. Celicas in the 70s were the same thing, in 4cyl 2 valve form. The ITBs are nothing special when you consider that the same Celicas had twin Solexes on them, and so had throttle plates in the exact same place. There's no variable valve timing, no variable inlet manifold, which even other RBs had either before the 26 came out or shortly afterward. The ECU is pretty rude and crude. The only things it has going for it are that the physical structure was pretty bloody tough for a mass produced engine, the twin-turbos and ITBs made for a bit of uniqueness against the competition (and even Toyota were ahead on the twin turbs thing, weren't they?) and the electronic controls and measuring devices (ie, AFMs, CAS, etc) were good enough to make it run well. Oh, and it sounds better than almost anything else, ever. The VR38 is absolutely halfway between the RB generation and the current generation, so it definitely has a massive increase in the sophistication of the electronics, allowing for a lot more dynamic optimisation of mapping. Then there's things like metal treatments and other coatings on things, adoption of variable cam stuff, and a bunch of other little improvements that mean it has to be a better thing than the RB26. But I otherwise agree with you that it is approximately the same thing as a 26. But, skip forward another 10 years from that engine and then the things that I mentioned in previous post come out to play. High compression, massively sophisticated computers, direct injection, clever measuring sensors, etc etc. They are the real difference between trying to make big power with a 26 and trying to make big power with a S/B50/54 (or whatever the preferred BMW engine of the week is).

      Is the RB26 actually that far off the mark? Honestly from where I'm sitting a VR38DETT is not actually that much more advanced than the RB26. Yes, there is a scavenge pump on the VR38, it's smarter in a number of ways but it's not actually jumping out to me as alien technology. Something like a B58 or V35A-FTS on the other hand has so many surprising little design features that add up to be something that just isn't comparable.
