105a to 105n while FIGS. 4C and 4D depict the integrated generators 101a to 101n after a portion of each rotor 101a to 101n is inserted into the engine crank case 107 and is encompassed, covered or adjacent to a respective stator 105a to 105n in order to illustrate the fact that once inserted into the crank case 107, only approximately one half of each rotor 101a to 101n (i.e., a “portion” or “percentage”) is inserted into the crank case 107 during a time period while the other approximately one half of each rotor 101a to 101n is not inserted during the same time period and remains outside the crank case 107.

In embodiments, the portion of each rotor 101a to 101n that is inserted in the crank case 107 may be cooled by a number of alternative techniques, including, but not limited to, a combination of oil sprayed onto the embedded rotor portions (spray inlets not shown in figures) and/or passageways while the portion of each rotor 101a to 101n that is not inserted in the crank case 107 may be cooled by a number of alternative techniques, including, but not limited to, fans or passageways or some combination of such colling methods.

FIGS. 4A to 4D also illustrate electromagnets or an electromagnetic material 106a to 106n on the surface of each rotor 101a to 101n. In embodiments, the electromagnets may be configured as strips of magnetic material composed of one or more known materials positioned on and around the circumferential end or rim of each rotor 101a to 101n.

Further, each piece of electromagnetic material 106a to 106n may be separated from another piece of electromagnetic material 106a to 106n by a piece of known non-electromagnetic material (see FIG. 6 and elements 154n).

As noted above, each generator comprises at least one rotor 101a to 101n and at least one stationary section (i.e., a “stator”) 105a to 105n. It should be understood that each respective rotor 101a to 101n may be configured in a parallel, geometric plane as a respective stator 105a to 105n, for example.

In embodiments, each stator 105a to 105n may comprise a surface 111a to 111n (see FIGS. 4B and 4D that show only one of the surfaces 111n) that may be configured and shaped to receive the inserted portion of a respective rotor 101ato 101n. Though inserted, each inserted portion of a rotor 101a to 101n does not touch a respective surface 111a to 111n (i.e., there is a gap in between an inserted rotor portion and the surface). Along each surface 111a to 111n there may be positioned stationary magnets (see FIGS. 4B and 4D) that are a part of each integrated generator 110a to 110n.

FIG. 4E depicts yet another illustration of the engine 100 with a focus on the portions of each rotor 101a to 101n (e.g., its electromagnets) that are inserted into the engine crank case 107 such that they are encompassed, covered or adjacent to a respective stator (stator not shown) in order to once again illustrate the fact that once inserted into the crank case 107, only approximately one half of each rotor 101a to 101n and its electromagnets is inserted into the crank case 107 during a time period while the other approximately one half of each rotor 101a to 101n is not inserted during the same time period and remains outside the crank case 107.

Referring now to FIG. 4F there is shown a close up view of a generator 110n. For the reader's guidance, the left side of FIG. 4F is a cut-a-way view of the generator 110n with its stator and windings removed (as an illustration) to enable the reader to see the electromagnets 106f and 106g of a rotors 101f, 101g underneath the stator windings while the right side of FIG. 4F includes the stator 105n and its windings 108n within crank case or endcap 107. FIG. 4F also illustrates passageways 112n for holding oil which allows the oil to be distributed to the electromagnets 106n in order to cool portions of the rotor 101n.

FIG. 4G depicts an enlarged view of a single integrated generator 110n according to an example of the present disclosure. As shown the stator 105n comprises one or more (i.e., a plurality) of electrical windings 108n, it again being understood that each stator 105a to 105n comprises such respective windings. As noted elsewhere, in an embodiment of the present disclosure the exemplary windings 108n may comprise coils of insulated wire configured around a laminated core. FIG. 4G also depicts: (i) the position of an exemplary piston arm pin 113n that may be connected to, or a part of, the piston arm 103n (see FIGS. 4A and 4C) that connects the piston arm 103n to the rotor 101n which comprises, and may function as, a circular crank weight; crankshaft section 102n; and electromagnets 106n. In this embodiment the stator 105n (i.e., its windings 108n) encompasses, covers or is adjacent to 50% of the electromagnets 106n of a respective rotor 101n.

Referring now to FIG. 4H there is yet another view of generator 110n. In this view both the rotor 101n and its electromagnets 106n (squares underneath each winding 108n) and the windings 108n of the stator 105n are shown though the endcap or crank case upon which the stator and its windings reside and that covers the windings 108n and stator 105n has been removed.

Though not shown in the figures, it should be understood that control electronics for controlling the output of the integrated generators described herein may also be included in the exemplary engines described herein. In an embodiment, such control electronics may be positioned inside an engine crankcase endcap, for example though this is just one of many positions where the control electronics can be located.

It should be understood that while a figure may illustrate only one exemplary, integrated generator (e.g., generator 110n) that integrated generators 110a to 110n may be constructed and operate similarly, where each of the generators
