Building the Atkinson Differential Engineby Vincent R. Gingery
Synopses & Reviews
You learn not only how to build this particular engine, but you learn the general skills that can be applied to all engines: patternmaking, molding, casting, boring, lapping, and all the rest.
Contents include: building a wooden mockup, casting, patternmaking, side panel pattern, side panel molding procedure, front & rear panels, oscillating arm patterns, piston rod pattern, preparing the base, assembling the main frame, boring crankshaft bearings and arm pivots, the ignition plate, the water jack assembly, making a copper lap, milling the cylinder ends, mounting valves on the cylinder, the electrical system, and much more.
This 1886 engine predates the Atkinson Cycle engine. The front panel is about 8" tall. A pair of 1-1/8" bore by 2-1/4" stroke pistons drive a 8-3/4" diameter flywheel. The arms of this engine move the two pistons toward one another in such a way as to compress and ignite the fuel charge so that all four strokes are completed in one revolution of the flywheel. The action looks like a street corner con man running a shell game!
Loaded with drawings, photos, specs, and wall-to-wall detailed how-to. More of the usual quality that always come out of Gingery Publications.
