fuel evaporation & injectors

Basically, they eliminate the "swirl" problems around the valve when the
fuel/air mixes, and the fuel is injected directly into the cylinder,
supposively to atomize it much better.  Maybe, maybe not.  I can't really
tell, but what they are doing is running the engines increadibly lean
during non-load periods (coasting, downhill, idle, etc) on alternating
cylinders, so there is enough "ooomth" to rotate the crank, but doesn't
really blow a lot of fuel.  This is how they achieve their high-mileage
claim, at least according to the documentation.

More than likely, it shall be the wave of the future.  After all, why
bother re-inventing an entire engine when you can just manage it
differently.  Costs less :)

Excuse the sarcasm.  I'm always fascinated by new ideas.  There's a guy
somewhere (saw it in HotRod) who is making a high-torque low-HP rotary
engine, a 3 cycle engine, I'll look for the article and post the issue
date, and there is a website in Tiawon or Korea with an interesting
high-torque 1 cyl engine, that can be duplicated and run in parallel,
giving a whopping 1/2" stroke.  All attempts at achieving the same thing.
Great mileage, okay power, and lots of government grant money.

Excuse the sarcasm again :)
