Abstract:
The present invention teaches an engine system apparatus and method that converts pulsed electromagnetic energy into mechanical force and motion. The engine apparatus combines the reciprocating action of an internal combustion engine and utilizes electrical energy to produce a magnetic field that initiates a repelling power stroke that is maintained in a reciprocating state by a movable magnet that is attracted to a stationary electromagnet member of the system. An electrical power source is pulsed ON to repeatedly produce the repelling power stroke and pulsed OFF to repeatedly allow the movable magnet to attract to the stationary electromagnet. The underlying principles of the electromagnet engine allow engine configurations to be built having one stationary electromagnet and one movable permanent magnet.

Description:
FIELD OF THE INVENTION 
     This invention relates to engine apparatus and methods for producing work at an output thereof. More particularly, the present invention relates to electrically powered engine apparatus and method of producing work at an output thereof. Even more particularly, the present invention relates to electromagnetically powered engine apparatus that produce work at an output thereof by means of combining electromagnet devices to drive a mechanical arrangement of elements to produce propulsion useful in vehicles and other power input dependent apparatus. 
     DESCRIPTION OF THE PRIOR ART 
     The principles of work are considered well known to the artisan as they relate to rectilinear and rotary motion of an object, suffice it to say that it concerns the transference of energy produced by the motion of an object by application of a force and is measured by the product of the force and displacement of the object. The internal combustion engine is a known apparatus employed to perform work by cranking a crankshaft. The advantage to mankind in having the internal combustion engine, is without question, superior to other tools developed by man to manage the daily tasks of living, including the electric motor whose rotor equates to the crankshaft in performing work. The internal combustion engine has had much research attention and has been perfected to yield great satisfaction in work efficiency, torque and speed, but, while the advantages are recognized by all, the polluting disadvantages to the environment have been largely ignored to the detriment of society. Electric motors have replaced many machine application formerly relying on the internal combustion engines, and while they have also enjoyed much technological advances, they have not been perfected to the point of replacing the greatest source of pollution, namely the automobile engine, (see Wall Street Journal Articel entitled: &#34;GA Says It Plans an Electric Car, but Details Are Spotty&#34;, page B1, dated Thursday Apr. 19, 1990). 
     The internal combustion engine requires timely firing of a spark within a cylinder chamber having gone through a compression stroke to produce the power stroke that moves a piston/rod in a reciprocating manner to drive a crankshaft having a power output attachment. The end-use apparatus of the power output attachment are many, and include the automobile which has required many engine variations and cylinder block configurations to harness the energy produced at the crankshaft that results into propulsion of the automobile. The electric motors traditionally require large battery units to continually produce rotating drivetrain power, and as alluded to in the Wall Street article, have yet to be commercially attractive as an alternative engine technology. 
     Therefore, a need is seen to exist for an engine apparatus that maintains the attributes of an internal combustion engine, including high performance parameters such as horsepower ratings, speed and torque packaged in a small volume and that further includes the non-polluting attributes of an electric motor without the need for large storage battery units. 
     SUMMARY OF THE INVENTION 
     Accordingly, the primary object of the present invention is to provide an engine apparatus having high performance parameters, such as horsepower ratings, speed and torque without the disadvantages of an internal combustion engine, primarily pollution associated with the use of petroleum products. 
     Another object of the present invention is to provide an engine that operates clean similar to the electric motor but that is more efficient in the conversion of electrical energy to mechanical energy. 
     A related object of the present invention is to provide a vehicular apparatus that utilizes an engine having the foregoing objects. 
     Yet another object of the present invention is to provide a method of cranking a crankshaft using an engine having the foregoing objects. 
     The present invention provides the foregoing objects by providing an engine apparatus that combines the reciprocating action of an internal combustion engine but that utilizes electrical energy to produce a magnetic field that initiates a repelling power stroke that is maintained in a reciprocating state by a movable magnet means that is attracted to a stationary magnet means. A power source is pulsed ON to repeatedly produce the repelling power stroke and pulsed OFF to repeatedly allow the movable magnet mean to attract to the stationary magnet means. The underlying principles of the engine allow engine configurations from at least one stationary magnet means and at least one movable magnet means. 
     Therefore, to the accomplishments of the foregoing objects, the invention consists of the foregoing features hereinafter fully described and particularly pointed out in the claims, the accompanying drawings and the following disclosure describing in detail the invention, such drawings and disclosure illustrating two of the various ways in which the invention may be practiced.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     By Example, FIGS. 1 and 3 are embodiments 100 and 200 of the present invention analogous to a six cylinder internal combustion engine. The analogy is limited, however, to the reciprocating nature for turning a crankshaft 600 to produce output power drive motions M11 at driveshaft ends 101 and 102, respectively. Before detailing the primary elements of the present invention as embodied in FIGS. 1 and 3, it is believed best to briefly discuss the magnetic phenomenon involved in operation of the engine apparatus of the present invention. As best understood from a rudimentary electrical block diagram 300 shown in FIG. 4, a power source, such as a 12 v battery source 301 inputs current I1 and voltage V1 to step-up coil 302 that outputs voltage V2 and current I2 to a timed on/off electrical energy switch 303 that can direct timed electrical impulses TP, via either inputs A, B or C, to electromagnet means 400 to return current I3 to power source 301. Electromagnet means 400 comprises a coil member 401 and a magnet core member 402, coil member 401 is believed to contribute a counter electromotive force component of current Icemf to return current I3 that helps to maintain the charge on power source 301. For reasons believed to be attributable to parallel resistance effects, electromagnet 400 can deliver higher magnetic field strength with less heat build-up in the coil if coil 401 is wound using twisted pair of magnet wire as opposed to winding the coil using a single strand of magnet wire of the same geuge. Magnet core member 402 is preferably a soft magnetic material operable under cyclic magnetized conditions from timed pulse TP to produce magnetic poles N and S thereon said core member 402. Arranged in close magnetic coupling relation to electromagnet means 400 is a movable permanent magnet means 500, whose hard magnetic material is selected to have a permanent magnetic member 503, 703 having polarized state N or S identical to the polarity of adjacent side of electromagnet core member 402. The object of such arrangement being to force movable permanent magnet means 500 to produce reciprocating motion RM about slide supports 501, 700 by successive repelling and attracting power strokes to produce simultaneous work output W1 and W2. The repelling power stroke being initiated by a single pulse TP from power source 301, 302, 303 that polarizes core member 402 as shown, i.e. with a magnetic polarity N identical with the polarity of the adjacent permanent magnet 503, 702. During the off-state of TP, and hence the demagnetized state DM on core member 402, permanent magnet 503, 702 attract toward core member 402 to produce the attraction power stroke that completes one cycle of operation. Although FIG. 4 shows a pair of magnet means 500, it is to be understood that the reciprocating motion can be accommplished with only one such movable magnet means 500. Further, although a permanent magnet means 500 is discussed in the preferred embodiment, a movable electromagnet (not shown) could be employed having timed pulses that provide alternating magnetic repelling and attracting conditions in concert with stationary electromagnet 400. 
     Referring now to FIGS. 1 and 3 and recalling the above described one cycle of operation of the present invention, the plurality of six permanent magnet means will now be discussed. It should also be understood that the force in the repelling and attraction power strokes, designated M1, M2 and M3, M4, M5, M5, respectively, in FIGS. 1 and 3 is a function of the magnetic materials used in core memeber 402 and in permanent magnet members 503 and 702, as well as efficiency factors associated with the electromagnet means 400. The repulsion and attraction forces determines the torque and revolution per minute delivered at outputs 101 and 201. In FIG. 1 an engine 100 is built upon a base 800 whereon three electromagnetic means 400 are centrally located about symmetrically arranged permanent magnet means 500. Each electromagnetic means 400 has coil 401, a core member 402 and support end plates 403, said coil 401 being electrically coupled via inputs A, B, and C from a power source such as the power source illustrated in FIG. 4. Upon each input terminal of coil 401 receiving an electrical pulse TP to power electromagnet 400 ON, the magnetic field produced causes core member 402 to be magnetically polarized S, N, left to right, as shown in FIG. 1. By design, an opposite polarity on core 402 would result if TP were to be invertedly applied. It should be understood that in the symmetrical arrangement of FIGS. 1 and 3, only one electromagnet means is ON to repel the axially opposed movable permanent magnet means 500, as indicated by repelling motion force arrows M1 and M2, while the other two electromagnet means 400 are OFF with movable permanent magnet means 500 in a state of being attracted toward the respective core members of the electromagnet means 400 as indicated by attracting motion force arrow M3, M4, M5, M6. As shown in FIG. 1, permanent magnet means 500 on the right side have permanent magnet members 503 polarized at N while the permanent magnet members 503 on the left are polarized at S. 
     FIG. 2 shows an enlarged view of the movable permanent magnet means depicted in FIG. 1 wherein a rectangular geometrical structure 502 encases the permanent magnet 503. Rectangular structure 502 is free to move by virtue of extending flanges 502a being slideably supported on ball bearings 501a attached on a bottom side of support channels 501. The principles of operation are as discussed above, and depend on pulsed enerigization of electromagnet means 400. Permanent magnet means 500 is pivotably coupled to a rod member 504, which rod member 504 is pivotably coupled to a crank 601a of crankshaft 600. Each permanent magnet member having its respective rod coupled to the cranks 601a, 601b, and 601c. FIG. 7 shows a side view of the electromagnet means-permanent magnet means engine of FIG. 1 wherein of interest is the angular positions P1, P2 and P3 of the cranks 601a, 601b and 601c, which positions are preferably at 120 degree offset between each crank. Upon crank 601a receiving motion M1, resulting motion M7 is imparted on crankshaft 600 which transfers the produced power to transfer means TM1, such as a belt drive, in the direction M8 and onto power output shaft 101 as outpower drive having motion M11. The symetrical left hand side operates simultaneously in that M2 produces motion M10 which transfers the power via transfer means TM2 and produces complementary power combinable at shaft 101, as indicated by force motion arrow M9. Utilization of the produced output power at shaft 101 are many, but preferably includes a vehicular application, not shown, where a drivetrain, axle and wheels are attached to output 101 for effecting propulsion. 
     Referring now to FIGS.3, 5, 6 and 8, engine 200 operates in a similar manner as engine 100 shown in FIG. 1. Engine 100 and 200 differ primarily in their construction related to the movable permanent magnet means. Engine 200 is built on the block and cylinder concept of the internal combustion engine. Thus, a block 700 supported on base 800 having a plurality of symmetrically arranged cylinder chamber 701 are positioned flanking a plurality of centrally supported electromagnet means 400, here three electromagnets 400. A permanent magnet means 702 in the form of a ringed piston-like device is adapted having a permanent magnet 702a placed interiorly. Frictional consideration would require having a suitable lubricant L between the walls of the chamber 701 and piston-like permanent magnet means 702. Further, rod member 703 would require a bore 704 sized to accommodate upward and downward travel during the reciprocating action RM. Also shown in FIG. 3 are bolt means 403 for attaching electromagnet means 400 to the sides of block 700. FIG. 5 is a plan view, showing additionally, the placement of main bearings MB on crankshaft 600 and the interface repelling magnetic force MF that causes the repelling of the piston-like permanent magnet means 702. FIG. 6 shows a side view of engine 200 and the associated travel of rods 703 as the cranks 601a, 601b and 601c rotate from position P1 to P2 to P3. FIG. 8 shows a side view of the electromagnet means-permanent magnet means engine of FIG. 3 wherein of interest is also the angular positions P1, P2 and P3 of the cranks 601a, 601b and 601cwhich positions are also preferably at 120 degree offset between each crank. FIG. 8 further shows the close magnetic interface between the electromagnet&#39;s core member 402 and the permanent magnet member 702a to repel the piston-like device 702 and the symbolized demagnetized state DM that results in piston-like device 702 being attracted to core member 402. Additionally, the mechanical interface for attaching plates 403 are detailed as well as a power source comprising of the components 301, 302 and 303 as shown in FIG. 3. 
     Therefore, while the present invention has been shown and described herein in what is believed to be the most practical and preferred embodiments, it is recognized that departures can be made therefore within the scope of the invention, which is therefore not to be limited to the details disclosed therein but is to be accorded the full scope of the claims so as to embrace any and all equivalent apparatus.
