[Diy_efi] GDI cont'd

[efi student]

It sounds like you want to go to a place that has been pretty thoroughly
examined by these people:

http://www.orbeng.com.au/orbital/engineeringServices/ems.htm

They were doing this kind of research about 10 years ago, and promised a =
GDI
two stroke for automotive use that turned out to be vaporware, despite a
number of successful prototypes.  If you haven't started there, you =
might
want to investigate their results (at least what they will share).

to those who were asking, we want to use the GDI on a 2-stroke because =
it
will=20
be capable of injecting after the exhaust port is closed. Normally fed=20
2-strokes have horrible fuel economy as the (valve overlap, i guess you
would=20
call it) is huge.

Doing this, we in theory will be able to get the power of a 2-stroke =
with
the=20
emmisons and economy of a 4-stroke. I am guessing that the injectors =
should=20
already be oversized somewhat, due to the fact that they are designed =
for a=20
car engine, not a snowmobile.

Couple this with a supercharger, and we could see numbers near 180 hp.
