Abstract
An electrical generator utilizing two internal combustion engine having an expanded range of power output is disclosed. A primary internal combustion engine is coupled to the magnet rotor assembly. The primary engine is operated solely in a lower power range. A secondary engine, coupled to a coil assembly is locked in place in such lower power range to make the coil assembly stationary. In a higher power range, that overlaps the lower power range, the secondary engine is unlocked and operated to rotate in a counter-rotating direction with respect to the first engine. The secondary engine can be started by operating the generator (consisting of the magnet rotor assembly and the coil assembly) as a motor by appropriate application of current.
