An electric device has a driveshaft with at least one stator cylinder positioned between opposing, curvilinear shaped cams mounted on the driveshaft, where the center axis of the stator cylinder is parallel with but spaced apart from the driveshaft axis. A magnet assembly is disposed in each end of the stator cylinder, with one magnet assembly engaging one cam and the other magnet assembly engaging the other cam. Each magnet assembly includes a cam follower that can move along a curvilinear shaped cam. A magnet slide arm attached to the cam reciprocates magnets carried on the magnet slide arm through electromagnetic windings disposed around the stator cylinder. An electrical input delivered to the windings can reciprocate the arm, driving the cams to rotate the driveshaft. Alternatively, rotation of the driveshaft can be used to reciprocate the arm to induce electric current in the windings.

An engine-generator set with a single-cylinder diesel engine and an electrical generator with a rotor secured to the engine crankshaft. The rotor is cantilevered on an end of the crankshaft. The engine has an electrically activatable fuel injector connected to a continuously pressurized fuel supply, such as in a common rail injection system. The engine exhaust passes through a catalyst bed. In a marine version, the catalyst bed is disposed within an injection elbow.
