Use of a Cruciform Shaped Mechanism for Application to Internal Combustion Engines for Portable Auxiliary Power Equipment 911269

The unique shape of cruciform engines provides an alternative to the typical in-line or “V-shaped” engines. The planar nature of the mechanism provides either a low profile or thin engine with the ability to stack many 4 cylinder banks into a compact large engine. The sinusoidal motion inherent in this mechanism provides unique balancing aspects which ultimately further reduce the size of the power plant. The compact cruciform shape lends itself to applications in portable hydraulic pumps, compressors, hydraulic motors, internal combustion engines, etc.
