Re: 45% efficient F1 ICE engine ?

They are quite clear that the bulk of the gains is from the MGU-H. ( motor/generator unit- heat recovery) which uses a turbine in the exhaust to drive a generator providing up to 120 kW's, intermittently , which is stored in a battery, and then reused to drive the same unit when needed to produce b...

Re: 45% efficient F1 ICE engine ?

I wouldn't like to speculate on the efficiency of an F1 engine, but for medium-sized stationary diesel engines the efficiency is usually based on a third of the energy of the fuel going to each of mechanical output, exhaust heat and jacket-water heat. So yes, if you can recover half the energy bein...

Re: Strange sound in the sky all around the world in 2012

I have heard a very strange sound in the sky. 1 or 2 years ago in the summer, very roughly 2 in the morning. I don't keep a diary and don't have a photographic memory. I began to notice a sound a few times that seemed to originate in the treetops surrounding me as I sat in my favorite chair in my ya...

Re: EV transmissions and Popular Science

All of the recent balony has been obfuscative of an important issue. On a race track, under a specific set of conditions, it can be most advantageous to eliminate a gear train. This can eliminate friction loss portrayed by a generic "Rule Of Thumb" 10%, or, in more specific conditions, such as NASCA...

Lukey, pretty baby, it is not obvious that you know what I'm talking about when I write about the 70% loss in the normal electric motor operated in varying load and RPM conditions. So, why don't you explain to us how and why the normal motor has been losing 70% of its input power for over 100 years?...

Re: EV transmissions and Popular Science

The standard engineering Rule Of Thumb for the small amount waste is 10% loss of the inputted power for each case of one gear meshing with another in the drive train. That's why in car talk, manual transmissions are figured to lose 10% and slushomatics lose 30% of the flywheel power. Not even close...

Re: EV transmissions and Popular Science

They only use the reduction now because they haven't matured motor geometry sufficiently yet. There is nothing gears can do that a magnetic geometry can't be setup to do, and then you skip the frictional loss and cost and failure modes of the gearing stage. As usual, Luke, you " explain" using only...

Re: EV transmissions and Popular Science

When comparing a 1 speed vs a 2 speed EV design you have to pick some metric to match. Here you can see what happens when you pick the gear ratios such that the 0-100km/h time is the same. You can see with a UDDS driver cycle the cars goes about 12 miles farther in this case with the single speed t...

If I'm not mistaken, the power electronics required to render mechanical transmissions irrelevant also incur cost, weight, volume, and inefficiency-- just like mechanical transmissions.

I get the torque/ power /rpm thing, but I are you saying you could get this 10x torque with no major implications to the drive controls/inverter etc ?
