ABSTRACT:
An internal combustion engine has an annular engine chamber in which a set of pistons oscillate in synchronism. On their compression stroke, the pistons draw in a fresh charge into the chamber behind the piston. On the power stroke, that charge is compressed and released into the next following combustion chamber. The engine geometry is selected to provide a a compression stroke that is shorter in duration than the combustion stroke.
