Re: [Phys-l] Hybrid mileage

["Rauber, Joel" <Joel.Rauber@SDSTATE.EDU>]

In the old days, before my time, (though a note in a moment), one had a manual choke and you would artificially give your car high revs when you first started up.

High revs (larger than (warmed-up) normal idle speed are revolutions per second.

The first car I ever owned or bought (a 1977 Honda Accord) had a manual choke.  That was very unusual at the time; but it was one of many factors in my decision to purchase that car.  The choke would automatically turn itself off.  I don't know if really old cars (say pre-1960) if the manual chokes had to be manually turned-off?

Why aren't you walking or using a bicycle?

bc, puzzled by the "high reves.";  never noticed.

Yes, the first few tenths the MPG is ~ 15 -- probably as bad, relatively, with any 'bile.
