 My friends Honda is labled as that and it is not a hybrid. The best any of us
 can figure is that it makes no emissions when iot is parked with the engine

   Do not expect logical terms ;-) Some time ago I actually found the
   description for Nixie tubes are neon filled vacuum tubes on Ebay.
   There are no words...

  Hybrid cars, here in the US, are officially listed as partial zero
  emission.

My mother's non-hybrid Toyota Camry is also a PZEV. I'm told that this
means that some of the time while the vehicle is running, the engine's
fuel supply is cut off completely. For non-hybrid vehicles, this could
only be while coasting at speed with the throttle closed. I guess the
automatic transmission must be specially designed to keep the engine
turning over with the torque input from the wheels.

Turning off the injectors in the upper gears of an auto transmission car
while the throttle is closed is a common practice for electronic fuel
injected engines.  I can tell it is occurring in my car when the MPG
computer displays --- instead of some ridiculous number up to 199 MPG when
coming off the freeway. 

Yes, the torque converter linkage is such that at speed the wheel spin will
drag the engine crankshaft along with it and the non-fueled air pumping
action of the engine is acting like a brake.

Shift into neutral actually gets you worse MPG, since you're then using gas
to idle the engine where none would be otherwise needed to keep the crank
spinning.

Lower gears then get gas added to bring back the engine idle as the jerking
action of restarting the engine (akin to popping the clutch on a manual
transmission car) would be more pronounced and make for an unpleasant ride.

Of course none of this is orange glow related unless it happens to be the
car color, or the driver color, or both...
