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. Feel free to explore the large preview or order a full color print from Lulu.com/trnowry
