Momemade electro-turbo-charger-compounder

Post by Enola Straight »

Over at the SDMB I asked if such technology existed:
http://boards.straightdope.com/sdmb/sho ... p?t=438851
Essentially, a turbocharger which has an alternator/electric motor coupled directly to the turboshaft. The Idea would be to send electricity to the device to produce immediate boost, instead of waiting for it to spool up on its own ( this is called turbo lag). Once the desired boost level is reached, instead of releasing excess pressure with a wastegate, the device absorbs the kinetic energy and converts it to electricity, which is returned to the crankshaft by an electric motor.

Here is an actual example of this technology: the Dynacharger

scroll to the bottom.

Over on this board I realized that, if I were using AC, the frequency of current alternation would be rising above and below 60 hertz as the boost levels and engine rpm changes; 60 Hz the frequency of american AC, IIRC.

Does electrical equipment "used to" 60 Hz still work above or below that?

Most, if not all, electrical systems in US automobiles are DC, not AC.

That depends. Running a 60 Hz motor at 50 Hz will cause it to burn out quickly and possibly create a fire hazard, given that it was designed to use 60 Hz power. Something like a laptop or tv that was designed only for use with 60 Hz juice will probably be damaged or destroyed by connecting it to anything but 60 Hz power. Another consideration is that many timing circuits rely on 60 Hz power as a baseline; running them at anything else will cause their clocks to run fast or slow.

Regarding the rest of your post: I'm going to go put a pancake on a bunny's head and call it good :wink:
