Title: Multiple-choice piggyback ignition booster circuit for internal combustion engines and other motors

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to ignition circuits for internal combustion engines and, more particularly, to a multi-choice piggyback ignition booster circuit for motors. 
     Booster circuits for ignition systems are required to provide additional power for better performance; for instance, to compensate for unsatisfactory performance of the ignition system during starting. Current booster circuits, however, also have the following drawbacks: they are electronically complex, they are bulky in size, they do not have a built-in backup or default bypass system, and they have limited vehicular compatibility—i.e., they do not fit on all vehicles, for example, possibly working on foreign but not domestic vehicles. 
     As can be seen, there is a need for a multiple-choice piggyback ignition booster that has near universal vehicular compatibility—compatible with foreign and domestic, old and new vehicles—that incorporates a built-in bypass or default system, wherein the operator has the option to turn it on and off. The multiple-choice piggyback ignition booster embodied in the present invention provides additional power for better performance in terms of torque and efficiency, on demand. The device can perform as an addition to the stock ignition system or through a manually operable on/off switch, so that the multiple-choice piggyback ignition booster embodied is smaller than current solutions and is capable of being used on any gasoline powered motor.

     DETAILED DESCRIPTION OF THE INVENTION 
     The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims. 
     Broadly, the present invention may include a booster circuit for use with an ignition system for an internal combustion engine is provided. The booster circuit includes a relay control circuitry disposed in parallel between the voltage source and the one or more ignition coils for igniting fuel in the engine in synchronism with engine operation; a controllable switching element for selectively completing a booster circuit for connecting the relay control circuitry in series with the voltage source and the one or more ignition coils; and the booster circuit having electronic circuitry including at least one output for providing booster energy at the at least one output, when the booster circuit is completed by the controllable switching element to assure producing of a suitable voltage applied to the one or more ignition coils. 
     Referring to  FIGS. 1 through 7 , the present invention may include a relay control circuitry  10  selectively coupling an input circuitry  20  and a bypass circuitry  30  with output. The relay control circuitry  10  may include capacitors, diodes, transistors, resistors along with one or more switching elements  40  as indicated on the schematics. 
     The battery  50  may be connected to the fuse by an electrical connection, such as a 14-gauge wire. Vehicular voltage may be applied by the battery  50  through the fuse (provided by the input circuitry  20 ) to a first capacitor coupled to a diode connecting to a set of second capacitors connected to the normally open side of the relay control circuitry  10 . The normally closed side of the relay control circuitry  10 , which requires no power may be connected via the original power to the ignition coils (provided by the output circuitry  80 ). A single line from the relay control circuitry  10  may be connected to the ignition coils. The relay control circuitry  10  may be powered by the original source to the ignition coils. The switching element  40  may be an on/off switch that is put in series with the relay control circuitry  10  and the normal power source to the ignition along the same wire of the negative side of the relay control circuitry  10  providing ground. 
     A method of manufacturing the present invention may include the following. A manufacturer may utilize PC board to attach the electronic components including the diode to the positive side of the first capacitor. That line may then be connected to the normally open side of the relay control circuitry  10 , while the positive wire coming from the fuse to the diode, wherein the opposite side of the diode is now connected to the capacitors, and wherein the line from the capacitors is now connected to the normally open side of the relay control circuitry  10 . The original power wire for the ignition coils is now connected to the normally closed side of the relay control circuitry  10 . The positive side of the relays coil may be connected to a switch element  40  in series to the original power source to the coil. The negative side of the capacitors may be connected in series to the resistor. The resistor may be connected to ground. The negative side of the relay coil may be connected to ground. The output from the relay is now connected to the ignition coils. 
     To use the present invention, a user would install the present invention disclosed above to a gasoline powered vehicle and hook it up to the coils (output circuitry  80 ) and battery  50 . Currently this device should only be used in conjunction with the ignition system. Additionally, the device does have future potential applications for example “fuel injectors”. 
     It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
