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

assembly notes.
