The correct
terminology is
"atmospheric engine". Never
the less, here is a "flame
eater" engine
you can build any of four
ways: (1) - Air Cooled Side
Crank as shown,
(2) - Water Cooled Side Crank,
(3) - Air Cooled Center Crank
or (4) -
Water Cooled Center Crank!
The air cooled engines have an
optional belt driven cooling
fan which
provides cooling for long
running sessions. The engine
runs fine
without it. With the fan, the
engine will run all day long
and never
get hot. But long runs or not,
the fan also adds much
interest to the
engine.
All four versions use my
oscillating (twisting) side
shaft mechanism to
operate the head valve. My
unique valve seat is of self
lubricating
non-metallic material which
greatly reduces valve sliding
friction and
virtually eliminates wear. The
engine speed range is from 60
to 600 RPM
or so.
The
engine can be ran on an
alcohol flame, but for easy
and accurate speed
control, use my Mini
Propane
Burner on the "Book
Shelf Models, Tools,
Etc." menu.
The plans set consists of 19
sheets of drawings and 2
sheets of
construction and assembly
notes.
