The opoc® engine has very high power density of nearly one horsepower per pound resulting in an unprecedented lightweight and compact engine. The opoc® engine is perfectly balanced enabling stackable power modules. This unique modular displacement capability is one of the long standing, but elusive goals of engine engineers' quest for high efficiency. In addition, it also results in much less NVH than a conventional engine of comparable power.
