Diamond DA-40 with G-1000 pirep

Why "especially with all the accessories installed"?

-heavier high-pressure fuel pumps, lines etc which are not needed on gas
engines.
-on two strokes you need a supercharger to get them started.

Why is a 2-stroke cycle engine lighter than a 4-stroke?
-less stuff: with twice the power strokes per piston, one needs fewer
pistons and all associated stuff. For example the three cylinder Wilksch is
as smooth as a six cyl gas engine http://www.wilksch.com/

If only they could be lighter :-)

Aren't they also heavier, i.e., pound of engine weight per HP generated?

Every one of which I've read is heavier than an equivalent gas engine,
especially
with all the accessories installed. Since some of the new diesel designs
are
2-stroke, and most gas engines are 4-stroke, though, some of the newer
ones may
actually come in lighter than the equivalent gasoline engine (if they
ever make it to
production).

Help me out here.

Thanks.
