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.

Abstract: A fuel injector intended for use on an internal combustion engine contains an injector needle that is longitudinally driven by an ultrasonic actuator during the time the injector valve is open to provide an atomized fuel spray output of sub-micron droplet sizes. A piezoelectric disk stack is mounted within the injector housing to surround a portion of the injector needle component and is used to provide the mechanical ultrasonic stimulation to the injector valve at the end of the injector needle and set up a corresponding wave-front at the injector valve to atomize the fuel as it leaves the injector nozzle.

Abstract: An Opposing Piston Opposing Cylinder (“OPOC”) internal combustion engine combined with an externally mounted pre-ignition assembly with an internal swirl chamber to improve cold start and continuing operation. The pre-ignition assembly contains both a fuel injector and an ignition device that are in communication with the swirl chamber. The inlet/outlet passage opening that extends between the combustion chamber of the engine and the swirl chamber allows fresh combustion air to be forced from the cylinder of the engine into the swirl chamber during the compression stroke and allows the subsequently ignited plasma gases from the swirl chamber to enter into the combustion chamber as to the pistons reach their TDC positions.
