Abstract
A reciprocating internal combustion engine includes a siamesed piston bore having a configuration formed by the intersection of two circular cylindrical elements and a matching piston having a similar siamesed configuration. This cylinder configuration allows a four cylinder engine to be about 25% shorter with the same displacement as an engine having circular cylinders and the same stroke.
