Definitions
- the present Utility Model Patent application relates to a new form of coupling and diode positioning within a spark plug for internal combustion engines.
- the spark plug now treated differs from other conventional spark plugs in that it includes, internally in its structure, a diode that has the function of improving the transmission conditions of the energy that crosses the body of the spark plug from its connector (which is the terminal connected to the spark plug lead) to. his central electrode (which is the opposite end that is inserted inside the combustion chamber), however, continuing the research and imbued with the intention of continuous improvement of his previous patent, the inventor presents this application where the proposed differences and innovations It consists in the fact that said diode, in this utility model is fixed and connected to the terminal and the core of the central electrode by means of two conical contacts, provided with centralizing hole, and one of the conical contacts has a spring incorporated. IT'S Optionally further provided for the use of tubular spacer to allow the use of diodes of different diameters and lengths, so that the diodes are kept correctly positioned within the hole of the ceramic insulator.
- the proposed utility model patent application foresees and allows the installation within the spark plug of diodes of different lengths and diameters, possessing different electrical characteristics and construction processes, which enables the manufacture of spark plugs with different characteristics and also the use of diodes of the same characteristics but with some dimensional variation.
- Spark plugs are electrical components that are connected to the pulse source by means of a flexible cable that has at its end a terminal (pipe) that can be connected to the terminal of the spark plug itself.
- the opposite end of the spark plug comprises an external threaded terminal which can be mounted in an equally threaded opening and which is provided in the engine block in direct relation to the cylinder, which threaded terminal is at the end of which the electrode that generates the spark whenever the spark plug is electrically powered by the electrical pulse source.
- the functional characteristics of the spark plugs are determined by questions basically related to the type of material used and the electrode spacing and design that is incorporated into them.
- the spark plug is equipped with a diode which has the function of improving the conditions of the electric current that is supplied to the spark plug, thus resulting in better spark plug performance and consequently improving the engine performance characteristics which are directly linked to the efficiency. with which the air / fuel mixture burns.
- This technique of mounting a diode on the spark plug cable comprises the use of rubber connectors to protect the electrical contact points between the plug and the cable itself, and this type of plug is also used to protect the cable connection region. and the spark plug terminal.
- the assembly type 'usually adopted to incorporate this component has the disadvantage of allowing the occurrence of spots or regions where there is the phenomenon of leakage current, a phenomenon that should not only because of the simple loss of efficiency with regard to the energy level that is sent to the spark plug, but also because it can represent a possible risk of accident if the cable with such a defect is handled while the engine is running.
- the inventor based on the state-of-the-art product of his own, which has already had a number of advantages compared to conventional spark plugs, among which can be cited the fact that by relying internally on a unit From diode the spark plug itself now has its own increment in terms of improving the performance achieved in the burning of the air / fuel mixture.
- Said candle presented the diode unit connected directly to the internal circuit of the. This diode unit is positioned at a point located between the connector that receives the corresponding spark plug cable and the electrode that is the region where the spark generation occurs, however, while continuing its research, to obtain new characteristics. for the spark plug.
- the present utility application patent provides for the assembly of diodes of different diameters, lengths, manufacturing process and materials used for making them, according to the desired electrical characteristics for each spark plug.
- two contacts are used: a concave tapered contact "A” on the spark plug terminal portion that is inserted into the hole the thermal insulator; and a concave conical contact "B” with built-in spring, which promotes contact between the diode and the central electrode core.
- Said concave conical contact "B” due to the spring effect, keeps the diode pressed between the two concave conical contacts "A” and “B”, ensuring the efficiency of the electrical contact and allowing the mounting of diodes of different lengths. It also allows efficient mounting even if there is a slight difference in length due to the diode production process.
- This application for a utility model patent also provides a tubular spacer to be optionally used to compensate for the difference 'between diameters diode characteristics, and models. or different manufacturing processes, thus ensuring their centralized positioning relative to the orifice of the thermal insulator.
- a variant is provided in which the function of the spring connector is present at at least one end of the diode, which is shaped like a spring and also has a contact end. This way the diode itself has the contact and spring functions.
- spark plug that is the subject of this patent application may be manufactured to all models (and specifications) normally provided for the wide range of internal combustion engines currently in use.
- Figure 1 illustrates a sectional front view of the proposed spark plug
- Figure 2 illustrates an enlarged view of the detail "A" shown in Figure 1;
- Figure 3 shows a front view of the variant in which the diode has at least one of its ends configured as a spring.
- the overall configuration of the spark plug 1 has not been substantially altered as it has its traditional core 3, which runs through its ceramic body 4, which acts as an insulator, and around the lower portion 5 of said ceramic body . 4 the hexagonal terminal 6 is provided with a head 7 provided with thread 8 from which the electrode 9 projects.
- FIG. 1 above shows the fact that diode 2 (pictured schematically) is mounted between two concave concave contacts, a concave conical contact "A” in the terminal portion of the spark plug that is inserted into the insulator hole thermal; and a concave conical contact "B” with built-in spring, which promotes contact between the diode and the central electrode core.
- Said concave conical contact "B” due to the spring effect, keeps the diode pressed between the two concave conical contacts "A” and “B”, ensuring the efficiency of the electrical contact and allowing the mounting of diodes of different lengths. It also allows efficient mounting even if there is a slight difference in length due to the diode production process.
- the concave-concave contacts and the diode are between the two portions of the core 3, thus disposing accordingly. shape internal to the ceramic body 4.
- Figure 2 allows a detailed view of the electrode, conical-concave contact "A”, diode, conical-concave contact "B", the spring incorporated therein, the central electrode and the tubular spacer.
- Figure 3 shows a variant in which the spring-loaded connector function is embodied in at least one end of diode 2 ', shaped like a spring M' with contact end C seen in detail.
