Using the MGU-K as a generator to harvest directly from the ICE sound very inefficient?
I don't understand why they couldn't settle for a solution like Porsches from LMP, where they only had a generator, not a motor on the exhaust side, would be much simpler
G-UK action when the ICE would otherwise be throttled increases efficiency
this is used in all those hybrids
there is no fundamental difference between eg a GU-H only machine and an MGU-H machine
your car's alternator can act as a motor but it's blocked from acting as a motor
your car's starter motor can act as a generator but it's blocked from acting as a generator
yes there might be a cooling benefit realisable from using a machine as M-only or G-only
How is it efficient to take the energy from the fueltank, rund it through the engine at around 40% thermal efficiency, and then further down the MGU-K into the battery?? That means the energy content from the fuel will only be at around 39-38% when it makes it to the battery.
I know that having at MGU-H and a GU-H mechanically would be more or less the same, what im thinking about is you dont have to think about the the deployment of the MU-H which is one of the complicated things about it that made VAG wanting to get rid of it in the first place.
What im sayin is inbetween getting completly rid of the MGU-H, and keeping it, could be a compromise of just allowing harvesting energy, and not deploying it.
