HHOPP engine

The HHOPP engine design is a way of building HIGH DISPLACEMENT engines (internal combustion, stirling, and diesel) in incredibly small physical packages. With all other things considered equal, the HHOPP version of the same power and displacement engine will be 1/4 the size or smaller than conventional designs. The core achievement of the HHOPP is dramatic size reduction that drives manufacturing costs down and translates into large weight savings with no loss in power or efficiency.
