1. A system for power transfer, comprising:
- a primary internal combustion engine;
a secondary internal combustion engine;
a flywheel;
a first clutch having first and second portions; and
a second clutch having first and second portions wherein;
the first and second clutches each have an engaged position in which the first and second portions of the clutch rotate together and a disengaged position in which the first portion of the clutch rotates independently of the second portion of the clutch;
axes of rotation of the primary engine, the secondary engine, the flywheel, the first clutch, and the second clutch are substantially collinear;
the first portion of the first clutch is coupled to the primary engine such that the first portion of the first clutch and the primary engine rotate together;
the second portion of the first clutch is coupled to the flywheel such that the second portion of the first clutch and the flywheel rotate together;
the second clutch is disposed between the primary and secondary engines;
the first portion of the second clutch is coupled to the secondary engine such that the first portion of the second clutch and the secondary engine rotate together; and
the second portion of the second clutch is coupled to the primary engine such that the second portion of the second clutch and the primary engine rotate together.

11. A coupling system for power transfer, comprising:
-
a first internal combustion engine; a second internal combustion engine; a motor-generator; a first coupler selectably coupling the first engine with the second engine; and a second coupler selectably coupling the second engine with the motor generator wherein axes of rotation of the first engine, the second engine, the motor-generator the first coupler, and the second coupler are substantially coincident; and
when both of the first and second couplers are engaged, the first engine, the second engine, the motor-generator, the first coupler, and the second coupler rotate synchronously;a third coupler; and a power takeoff selectably coupable to the motor-generator via the third coupler. - View Dependent Claims (12, 13, 14, 15, 16)
