Abstract
A hybrid engine having a plurality of combustion power assemblies disposed about an engine driveshaft on which is mounted spaced apart cams, each combustion power assembly disposed between the cams radially outward of the driveshaft and having a combustion cylinder with a fuel injector mounted thereon and with a reciprocating piston assembly disposed in each end of the combustion cylinder. A cam follower is attached to each piston assembly and engages a respective cam. An electric power assembly may be mounted radially outward from the driveshaft and adjacent at least one cam as a radial power assembly or may be mounted along the driveshaft between the two cams as an axial power assembly.
