Inside this book you get step by step instructions showing how to build the atkinson differential engine as built from the original patent drawings by vince and dave gingery. The first atkinson cycle engine the differential engine used opposed pistons.

A Different Opposed Piston Engine
Not being content with already having an engine project going i decided to have a go at the vince gingery atkinson differential design.
Atkinson differential engine. The linkage action and peculiar differential motion of the two pistons working together in the same cylinder of this engine is hypnotic. This is another engine designed by mr atkinson in the late 19th century but it is quite unlike the atkinson cycle engine that is more familiar to people. The atkinson cycle engine is a type of internal combustion engine invented by james atkinson in 1882.
Building the atkinson differential engine. The atkinson cycle is designed to provide efficiency at the expense of power densitya modern variation of this approach is used in some modern automobile engines. 1878087231 after a year of constant work the differential engine book is finally ready.
But it was worth the wait. The second and most well known design was the cycle engine which used an over center arm to create four piston strokes in one crankshaft revolution. You learn not only how to build this particular engine but you learn the general skills that can be applied to.
Atkinson produced three different designs that had a short compression stroke and a longer expansion stroke. Atkinson differential engine 1885 i am building a 17th scale 1885 atkinson differential enginebut am having problems with the compression stroke. This first engine design was not commercially successful.
The first atkinson cycle engine the differential engine used opposed pistonsthe second and most well known design was the cycle engine which used an over center arm to create four piston strokes in one crankshaft revolutionthe reciprocating engine had the intake. I have too little compression but if you alter this the firing stroke suffers. This is the atkinson differential engine.
A few years later in 1887 atkinson designed another engine called the atkinson cycle engine which was a much better and more commercially successful design featuring intake and compression strokes that were shorter than the expansion and. Its been so long since i heard from vince i thought he was deceased deranged demented or all of the above.
