1. Field of the Invention
The present invention relates generally to internal combustion engines and, more particularly, to an electromagnetic array assembly incorporated into any suitable type of internal combustion engine for generating an electrical current. The generated electrical output is useful for both providing co-generative propulsion to the vehicle, as well as for operating on-board electrical systems associated with the vehicle.
2. Description of the Related Art
The prior art is fairly well documented with various types of internal combustion engines, including both those of the conventional push/pull and rotary drive variants. The objective in each instance is the desire to maximize power output and fuel efficiency of the engine design.
A first example of the prior art is illustrated in U.S. Pat. No. 6,240,884, issued to Lillbacka, and which teaches a valveless rotating cylinder internal combustion engine. At least one cylinder is rotatable along an inner circumferential surface of an engine housing. A piston rod extends from the piston and is movable longitudinally within the cylinder. The piston rod is in turn connected to a crankshaft such that, when the engine is powered, both the cylinder and crankshaft can rotate in either the same or opposite directions.
An exhaust opening is provided at a location substantially at the top portion of the cylinder and a corresponding exhaust port is provided in the housing such that, when the cylinder is rotated to the particular location along the housing, its exhaust opening comes into alignment with the exhaust port of the housing and so that the exhaust gases resulting from the combustion in the cylinder are evacuated directly outside of the housing. A gear mechanism converts the rotational movement of either the cylinder, crankshaft, or combination thereof, to drive the vehicle or a power generating device to which the engine is adapted.
U.S. Pat. No. 6,062,175, issued to Huang, teaches a rotating cylinder internal combustion engine which includes multiple cylinder blocks in series rotatably mounted in a single casing. The cylinder blocks each define multiple cylinders along a circumferential portion of the cylinder block and in order to receive a piston within each one. The casing forms multiple spark plug holes and defines multiple exhaust ports and multiple intake ports in the periphery thereof. Each of the cylinders is accessible to the spark plugs, the exhaust ports and the intake ports upon rotation of the cylinder block. The spark plugs, the exhaust ports and the intake ports of the various blocks are further staggered.
U.S. Pat. No. 5,080,050, issued to Dale, teaches a yet further variation of a rotary internal combustion engine having spherical pistons mounted in radially arranged cylinders formed in a stacked series of rotatable cylindrical members. A stationary cam surface is located around the rotatable member to maintain contact with the pistons. A stationary member located with the rotatable cylindrical member provides a fresh fuel mixture, withdraws exhaust products, and provides ignition as required. Power is taken from the rotating cylindrical members at the end of the engine through a planetary gear train.
Additional references of note include U.S. Published Patent Application No. 2005/0056327 A1, to Daut et al., which teaches an electromagnetic hydraulic valve, in particular a proportional valve for a controlling device for adjusting the rotation angle of a camshaft relative to the crankshaft in an internal combustion engine, and a method for the production thereof.
Kawamura, U.S. Pat. No. 5,069,422, teaches a valve electromagnetic force driving apparatus which opens the suction/exhaust valve of an engine by an electromagnetic force generated by an electromagnet. A freely reciprocatable movable permanent magnet having at least one pair of magnetic poles arrayed in the direction of reciprocation is connected to the suction/exhaust valve, and fixed magnetic poles opposing the magnetic poles of the movable permanent magnet are provided and similarly arrayed in the direction of reciprocation. The suction/exhaust valve is driven, to open and close, by electromagnetic attractive and repulsive forces acting between the magnetic poles of the movable permanent magnet and the fixed magnetic poles. A fixed electromagnet opposing a reciprocating side end face of the suction/exhaust valve is provided and is adapted to subject the valve to a force acting in the opening direction when the valve is opened and closed. The actual operating state of the suction/exhaust valve is sensed, and when the operating state differs from a control command, the suction/exhaust valve is forcibly closed and self-diagnosis is performed.
Also of note is European Patent Application No. 0 844 388, which teaches a control device for a coupling electromagnet in particular for a starter motor for a vehicle, operable to regulate the speed of engagement of the pinion of the ring gear in such a way as to avoid stresses, wear and noise due to excessive speed of engagement in the initial phase of the starting operation. The device operates in a closed loop with the feedback signal generated by an estimator.
The present invention discloses an electromagnetic array assembly incorporated into any type of internal combustion engine, such as by example in a rotary internal combustion engine of improved design, and which operates to maximize power output as well as fuel efficiency in operation. The electromagnetic array operates with the engine to maximize efficiency of driving forces associated with the engine's cylinders, and such as which are involved both with co-generative propulsion of the output drive components of the vehicle, as well as the supply of the vehicle's various electrical components.

Additional features associated with the outer case 12 include the provision of mounting brackets 26 extending from oppositely and circumferentially spaced locations associated with the end surface 15, and which serve to mount the engine assembly 10 to a desired location such as within an engine compartment associated with a vehicle (not shown).

Additional features associated with the rotary engine assembly include an exhaust manifold attachment stud 204, as shown in
In order to sequentially drive and actuate each piston, a spark plug 214 is mounted in a communicating and angularly offsetting fashion within each of the cylinders 84 and 210 (see also as best shown in the cutaway illustration of
A crankshaft bearing 218 is illustrated, see as shown in
In operation, cylinders 84, as well as removable male piston features 206 and cylinder 210, are attached to the ratchet plates 72 and which are in turn positioned with the bearings 218 on the crankshaft 60. The bearings 218 are housed in the assembled motor case 12, embossment 20, cover 36, and embossment 40 for the house crankshaft in order to maintain an axial relationship between the ratchet plate and crankshaft. The ratchet plate 72, along with cylinders 84 and 210, rotate upon the crankshaft bearings 218. The transfer of motion to rotate the crankshaft 60 is accomplished via the crankshaft brakes 66 engaging with the brake notches 74 of the ratchet plates 72.
As discussed previously, the preferred embodiment disclosed includes four cylinders, one of which incorporating the removable male 206 and female 210 features. The order of cylinder operation commences with a first selected cylinder firing, a second selected cylinder engaged in the exhaust cycle, a third selected cylinder generating the air intake cycle, and the fourth selected and remaining cylinder intaking fuel and generating compression for ignition.
As first selected cylinder 84 ignites, it is locked in position via the cylinder brake 184 being engaged with the brake locking notch 88. The brake 184 is secured to the brake receiver ring 44 by means of the brake encasement bearing pocket 48.
A further function of the piston brake is to provide a channel for the fuel mixture to be injected into the piston combustion chamber, through the brake receiver ring ports 50, brake ports 188 and the piston injector port 86. The fuel mixture is injected at the beginning of the compression operation, at which point the piston injector port 86 is closed off as the male piston feature generates compression with the cylinder feature.
In the succeeding step, the spark plug 214 ignites the compressed fuel for combustion and generates the forces necessary to rotate the mating piston in a rotational motion about the crankshaft. Rotation of the related components described above is controlled in one direction via the brakes.
Each cylinder 84 again includes a valve 100 for controlling the flow of intake air and exhaust fumes after ignition. Each valve 100 is actuated via an associated cam surface 46 of the brake receiver ring 44 and as the piston rotates within the engine. The brake receiver ring includes an inner diameter surface that provides a plurality of ten cam surfaces 46, and with these cam surfaces constituting a lesser diameter in relationship. These two surface relationships operate to actuate the valve, through contact with the valve ball end 108, causing the valve to open in its relationship to the opening of the cylinder combustion chamber. The end of the valve is further tapered to provide a tight fit with the cylinder intake/exhaust chamber 94 opening.
Each valve 100 is maintained in its closed state via valve spring 112, spring washer 116 and retainer clip 120. A groove 110 provides retention of the retainer clip 120 and the spring is assembled in a compressed state, whereby the force provided thereby maintains the valve in a tight closed position against the intake/exhaust chamber opening of the cylinder. The brake receiver ring 44 is further secured to the interior of the engine via the mounting bolts 197.
Intake air is supplied through the air filter 132, through the air intake nozzle 128 and air intake flow chambers 130 of the intake manifold 124, as well as through the intake slots 42 of the cover 36. This air is then passed through the ratchet plate holes 79 and piston intake chamber 94. The exhaust gases are passed through the intake/exhaust valve chambers 94 of the cylinder, through the ratchet plate holes 79, through the motor case holes 30 and then through the exhaust flow chamber 146 of the exhaust/cooling air manifold 142, and out its holes 148 and through the exhaust pipes 152 and 154. It is understood that each of the chambers include at least a single one-way valve which aligns with the piston intake/exhaust valve chamber of aperture 94.
Each cylinder includes a spacer plate 216 on the opposing side to that of the ratchet plate 72 and to provide a means to close the spacing between the related side of the cylinder and the interior surface of either the motor case or cover. The spacer plate 216 is further secured by attachment bolts to the cylinder through bolt holes in the spacer plate. Holes for cooling and air intake/exhaust to and from the cylinder are also provided in the spacer as well.
The cylinder 210 incorporating the removable male feature 206 is backed by the spacer plate 208. When the plate 208 is removed, the male feature 206 is allowed to retract into its attachment pocket 211, providing a means to assemble and disassemble the pistons within the motor assembly in a rotational fashion about the crankshaft. The spacer plate is retained in its pocket via the mounting of the piston spacer plate with its attachment bolts to the cylinder 210.
Required lubrication of the assembly 10 is provided by oil pumped through a pump and filter assembly 180 via oil lines 172 and 176 extending from the oil pan 166. As the oil is passed through the engine, it drains via gravity action down through the motor case slot 32, through the exhaust/cooling manifold 142 slot 150 and into the collection area 168.
As the oil enters the engine via the crankshaft port 64, it is disbursed through the crankshaft and out its ports in the center area at the brakes. The oil continues to flow, under pump pressure, through the ratchet plate ports 82 and bearing ports 220. Oil continues to be disbursed, via centrifugal forces to the pistons and all moving contact surfaces throughout the interior of the engine.
An additional feature of the present invention, as briefly discussed above, is the operation of the electrode (iron) laminates 158, secured in their respective pockets 160 associated with each piston. As the corresponding piston rotates within the engine, the passage of the laminates 158 to the electrodes 54 generates an electrical current to the spark plug 214 for ignition. The electrodes 54 are again further secured to the interior of the engine via the mounting bolts 197. It is also contemplated that the electrical current generating characteristics of the invention are capable of being utilized both for the cogeneration of power, i.e., concurrent electrical and mechanical inputs in the operation of the rotary engine, as well as separately operating to charge the batteries or to operate the motor assembly itself, in temporary fashion and in the absence of the combustion cycle.
Finally, the engine cooling system further includes the provision of cooled external air supplied by a fan located at the front side of the engine. Air is funneled through the shroud 136, as well as through the cooling slots 38 of the cover 36. Air flows through the engine internal chamber, around its internal moving components and through the ratchet plate cooling holes 78 and cylinder cooling holes 98. The cooling air exits the engine via the cooling slots 18 in the motor case 12 and through the cooling air vents 144 of the exhaust/cooling air manifold 142.
Having described my invention, and as previously stated, the electromagnetic array assembly can be presented in other and additional preferred embodiments, again in use with a variety of differently configured IC combustion engines, as will become apparent to those skilled in the art to which it pertains and without deviating from the scope of the appended claims.
The present application is a continuation-in-part of U.S. application Ser. No. 10/759,485, filed Jan. 16, 2004, and entitled “Rotary and Centrifugal Internal Combustion Engine Having Overlapping Cylinder Heads and Push Rods.”
