Abstract
Combustion engines with up to 48 cyl have been built. It is shown that this is neither accident nor fanciness when high specific power output is involved. As is demonstrated on hand of equations, the subdivision of a certain displacement into larger numbers of smaller cylinders brings about a substantial increase in power. At this time, for example, more than twice that of single cylinder engines. Values of highly developed motorcycle competition engines are compared with these theoretical results and an amazingly high degree of agreement exists. These laws are not limited to motorcycle engines, but may be used for other applications also.
