Profs, I was not pretending anything, I was talking technical facts which I am sorry to say you are not up to it and so you couldn’t understand, the least you should have done was not to comment not having the technical savvy to do so. Mark, thanks for the support, yes, you was right about the gearing, I will try to explain things a bit better. The KERS MGU is attached to the crankshaft on the front of the engine through a tiny spur gear gearbox and clutch, the gearbox output shaft is geared down at a ratio of 2:1 which means when the engine is running at 18k rpm the MGU is running at 36k rpm, the MGU functions both as a motor as well as a generator, when the driver is not using KERS and as long as the driver doesn’t use the brakes the MGU is disengaged by its own clutch and so it’s not rotating. To be continued.
