Abstract

An internal combustion engines sparking plug according to the invention contains a solid housing (2), which is an electric and thermal conductor. In its interior recess, a gas-proof, ceramic insulator (1) is located with central electrode (3), whose protruding end is located inside a cylinder (17) of the sparking plug. The bottom part of the housing (2) of the sparking plug is a truncated cone, and the side streaming holes (5) are designed in a radial pattern around the sparking plug on the cone sheath, whilst the streaming holes (5) are inclined towards the vertical axis of the sparking plug at the angle of 45° to 90°. At least two side streaming holes (5) are designed in a radial pattern around the cone sheath perimeter of the sparking plug. In addition to that, the sparking plug may have a single vertical streaming hole (13) and (16) in the mass electrode (10) of the sparking plug, designed coaxially with the electrode (3) of the sparking plug and integrated with a sparking plug bottom (11). The mass electrode (10) is homogeneous with a sparking plug's housing (2) or is a separate element (15) combined on a permanent basis with the housing (2) of the sparking plug. According to this variant the streaming sparking plug has been designed so that the initiation of the ignition inside the cylinder (17) of the sparking plug takes place in the central part of the cylinder (17) of the sparking plug, whilst the streaming holes (5) are positioned so that the flame that spreads inside the cylinder (17) of the sparking plug covers relatively as short distance as possible from the outbreak of the ignition to the streaming holes (5). In addition to that, to shorten the time the flame reaches the streaming holes £5) and thus hasten the moment of initiation of ejecting hot streams into the combustion chamber of the engine, a flange (12) inside the sparking plug has been used, which can occur in two variants, i.e. as a single part of the housing (2) homogeneous with the housing (2), or as a ring (14) embedded cold in the housing (2) or press assembled inside the housing (2).

Description

Combustion Engines Sparking Plug.

The subject of the invention. The subject of the invention is a sparking plug for fuel-air mixture powered combustion engines that is broadly applied in combustion engines used as drives of all kinds of vehicles, as well as mechanical devices.

Technical status quo. An internal combustion engines sparking plug with spark ignition Application No. P-384839 is known, where, depending on the location of the sparking plug mounting hole against the engine cylinder, the sparking plug is available in two basic variants. Version one is applied, when the sparking plug mounting hole is located centrally in relation to the cylinder - this solution is broadly applied in three-, four- or five-valve per cylinder combustion engines, and two DOHC [Double Over Head Camshaft] camshafts are used. And version two, when the sparking plug mounting hole is located aside of the cylinder. This solution is applied in two- valve engines with a single overhead camshaft located centrally along the axis of the SOHC [Single Over Head Camshaft] engine cylinders.

In version one, the sparking plug according to the invention, a sparking plug contains a solid housing, which is an electric and thermal conductor. In its interior recess, a gas-proof, ceramic insulator is located with central electrode, whose protruding end is located inside a cylinder integrated with housing. Around it, in the bottom part, holes in a radial pattern are designed that enable easy gas flow into the cylinder and outside the cylinder from the inside. Height of the cylinder is adjusted so that the piston does not hit the cylinder bottom while the engine is working and that gasses that get out of the cylinder interior via the radial pattern holes comprise as much area of the combustion chamber as possible.

In version two, the sparking plug according to the invention, contains a solid housing, which is an electric and thermal conductor, hi its interior recess, a gas-proof, ceramic insulator is located with central electrode, whose protruding end is located inside a cylinder integrated with housing, whose bottom is located diagonally, depending on the sparking plug inclination angle in relation to the engine's cylinder. In the bottom part of the cylinder, at the side of the combustion chamber and at one side in relation to the sparking plug's axis, there are holes in a radial pattern that enable easy gas flow into the cylinder and outside the cylinder from the inside. Height of the cylinder is adjusted so that the piston does not hit the cylinder bottom while the engine is working and that gasses that get out of the cylinder interior via the radial pattern holes comprise as much area of the combustion chamber as possible.

The essence of the invention. A spark ignition combustion engine sparking plug according to the invention is a solution that enables to significantly accelerate air-fuel mixture combustion effectiveness, which will significantly reduce fuel consumption in spark ignition engines. According to the invention the sparking plug is designed so that it can be used in engines with centre DOHC cylinder mounting hole against the sparking plug, as well as in SOHC engines fitted to the side against the cylinder mounting hole of the sparking plug. At the same time, depending on the shape of the combustion chamber, the relevant slope of the sparking plug streaming holes is used, so as to obtain the most efficient combustion of fuel-air mixture.

The streaming sparking plug according to the invention occurs in three main variants:

1 - Version one where the sparking plug according to the invention contains a solid housing, which is an electric and thermal conductor. In its interior recess, a gas-proof, ceramic insulator is located with central electrode, whose protruding end is located inside a cylinder of the sparking plug. The lower part of the sparking plug housing creates a cylinder whilst the side streaming holes of the sparking plug are angled at 90° around the vertical axis of the sparking plug. This type of the sparking plug according to the invention can be applied to the rotation timing engine, in which the engine combustion chamber is flat, and the DOHC engine with traditional poppet timing with mounting hole of the sparking plug centrally placed against the cylinder. Radially spaced streaming holes, are arranged on the circumference of the sparking plug in the number of at least two. hi addition to that, the sparking plug may have a single vertical streaming hole in the bottom part of the sparking plug designed under the sparking plug electrode, and at least two pieces of radially spaced streaming holes, designed in the bottom part of the sparking plug and inclined towards the vertical axis of the sparking plug at the angle of 15° do 45°. In the sparking plug according to the invention the asymmetry of the lateral diameter of the streaming holes can be applied. And so the as far as six streaming holes spaced each 60 ° are concerned, at one side of the axis of the sparking plug 3 holes may have a diameter greater than three holes on the other side of the axle. This solution will force a more efficient mixing of the fresh charge under the sparking plug electrode. The diameter of the streaming holes and their number are chosen so that regarding the internal volume of the sparking plug cylinder, suitably long for the engine combustion chamber ignition gas streams are obtained. Inside the housing of the sparking plug, at the bottom of the sparking plug cylinder, a flange has been designed, so the process of ignition and of the ejection of the ignition streams from inside the sparking plug is faster. The distance between the flange and the central electrode is greater than the gap between the electrode and the bottom part of the sparking plug, so as not to disrupt the proper ignition, which should be located between the electrode and the bottom part of the sparking plug, hi addition to that the sparking plug is characterized by two options of production, i.e. it can be made with non-insulated central electrode whose end protrudes inside the cylinder of the sparking plug, and the isolated central electrode whilst the insulation may consist of a separate ceramic sleeve glued to the sparking plug insulator, or the isolation may be a single element integrated with the isolator. Height of the sparking plug cylinder may not be too large to make the load combustion process inside the sparking plug proceed appropriately quickly.

2 - Version two where the sparking plug according to the invention contains a solid housing, which is an electric and thermal conductor. In its interior recess, a gas-proof, ceramic insulator is located with central electrode, whose protruding end is located inside a cylinder of the sparking plug. The lower part of the sparking plug housing creates a truncated cone whilst the side streaming holes of the sparking plug are designed radially around the sparking plug on the flange of the cone and the streaming holes are angled towards the vertical axis of the sparking plug at 45° to 90°. This sparking plug can be applied to the rotation timing engine, in which the engine combustion chamber is flat, and with traditional poppet timing both with the DOHC engines with mounting hole of the sparking plug centrally placed against the cylinder and with SOHC engines with mounting hole of the sparking plug aside the cylinder. Depending on the engine which the sparking plug is to be used with and which is closely linked with the shape of the combustion chamber, the relevant inclination of streaming holes is used. At least two radially spaced streaming holes are arranged on the circumference of the sparking plug cone jacket. In addition to that, the sparking plug may have a single vertical streaming hole in the bottom part of the sparking plug designed under the sparking plug electrode, and at least two pieces of radially spaced streaming holes, designed in the bottom part of the sparking plug and inclined towards the vertical axis of the sparking plug at the angle of 15° do 45°. In the sparking plug according to the invention the asymmetry of the lateral diameter of the streaming holes can be applied. And so as far as six streaming holes spaced each 60° are concerned, at one side of the axis of the sparking plug three holes may have a diameter greater than three holes on the other side of the axle. This solution will force a more efficient mixing of the fresh charge under the sparking plug electrode. The diameter of the streaming holes, and their number are chosen so that regarding the internal volume of the sparking plug cylinder, suitably long for the engine combustion chamber ignition gas streams are obtained. Inside the housing of the sparking plug, at the bottom of the sparking plug cylinder, a flange has been designed, so the process of ignition and of the ejection of the ignition streams from inside the sparking plug is faster. The distance between the flange and the central electrode is greater than the gap between the electrode and the bottom part of the sparking plug, so as not to disrupt the proper ignition, which should be located between the electrode and the bottom part of the sparking plug. In addition to that the sparking plug is characterized by two options of production, i.e. it can be made with non-insulated central electrode whose end protrudes inside the cylinder of the sparking plug, and the isolated central electrode whilst the insulation may consist of a separate ceramic sleeve glued to the sparking plug insulator, or the isolation may be a single element integrated with the isolator. Height of the sparking plug cylinder may not be too large to make the load combustion process inside the sparking plug proceed appropriately quickly.

3 - Version three where the sparking plug according to the invention contains a solid housing, which is an electric and thermal conductor. In its interior recess, a gas-proof, ceramic insulator is located with central electrode, whose protruding end is located inside a cylinder of the sparking plug. The lower part of the sparking plug housing creates a truncated cone whilst the side streaming holes of the sparking plug are designed radially around the sparking plug on the flange of the cone and the streaming holes are angled towards the vertical axis of the sparking plug at 45° to 90°. This sparking plug can be applied to the rotation timing engine, in which the engine combustion chamber is flat, and with traditional poppet timing both with the DOHC engines with mounting hole of the sparking plug centrally placed against the cylinder and with SOHC engines with mounting hole of the sparking plug aside the cylinder. Depending on the engine which the sparking plug is to be used with and which is closely linked with the shape of the combustion chamber, the relevant inclination of streaming holes is used. At least two radially spaced streaming holes are arranged on the circumference of the sparking plug cone jacket. In addition to that, the sparking plug may have a single vertical streaming hole in the mass electrode of the sparking plug designed coaxially with the sparking plug electrode and integrated with the bottom part of the sparking plug. The mass electrode is integrated with the housing of the sparking plug or is a separate element permanently combined with the housing of the sparking plug. The streaming sparking plug according to this variant has been designed so that the initiation of spark ignition in the chamber was located in the central part of the spark chamber. The streaming sparking plug according to this variant has been designed so that the initiation of the ignition inside the cylinder of the sparking plug is located in the central part of the sparking plug cylinder, whilst the streaming holes are positioned so that flames spreading from the central electrode inside the sparking plug cylinder, cover the shortest possible way to the streaming holes of the sparking plug, hi addition to that, to shorten the time the flame reaches the streaming holes and thus hasten the moment of initiation of ejecting hot streams into the combustion chamber of the engine, a flange inside the sparking plug may be used, which can occur in two variants, i.e. as a single part of the housing homogeneous with the housing, or as a ring embedded cold in the housing or press assembled inside the housing. The distance between the flange and the central electrode is greater than the gap between the central electrode and the mass electrode, so as not to disrupt the proper ignition, which should be located between the central electrode and the mass electrode. In the sparking plug according to the invention the asymmetry of the lateral diameter of the streaming holes can be applied. And so the as far as six streaming holes spaced each 60° are concerned, at one side of the axis of the sparking plug three holes may have a diameter greater than three holes on the other side of the axle. This solution will force a more efficient mixing of the fresh charge under the sparking plug electrode. The diameter of the streaming holes and their number are chosen so that regarding the internal volume of the sparking plug cylinder, suitably long for the engine combustion chamber ignition gas streams are obtained, hi addition to that the sparking plug is characterized by two options of production, i.e. it can be made with non-insulated central electrode whose end protrudes inside the cylinder of the sparking plug, and the isolated central electrode whilst the insulation may consist of a separate ceramic sleeve glued to the sparking plug insulator, or the isolation may be a single element integrated with the isolator. The streaming sparking plug according to this variant is characterized by a faster time of load total combustion inside the sparking plug cylinder, which as a result makes the combustion of fuel- air mixture inside the combustion chamber of the engine is even faster.

hi all three variants of the streaming sparking plug according to the invention, various ends of the central electrode can be used in order to obtain the most advantageous load total combustion in the sparking plug cylinder. And so the end of the central electrode of the sparking plug may be cylindrical, may have the shape of a truncated cone, may have a cylindrical shape with a spherical recess, may have the shape of a cylinder with a conical recess, and may have the shape of a cylinder with two perpendicular grooves.

The streaming sparking plug according to the invention requires proper control of the ignition advance angle, therefore a correction of operation of the ignition module is required. And so, for example, if the traditional sparking plug ignition timing is set so that at the idle speed of 800 rpm. ignition advance is set to 5° before piston TDC, so for the streaming sparking plug ignition advance according to this invention should hover at about 2° before piston TDC. However, in case of 2500 rpm. where for the traditional sparking plug ignition timing is set at about 25° before TDC, so at this rpm for the streaming sparking plug according to invention, ignition timing fluctuates at about 8° before the piston TDC.

In the sparking plug according to the invention the asymmetry of the lateral diameter of the streaming holes £5} can be applied. And so the as far as six streaming holes {5} spaced each 60 ° are concerned, at one side of the axis of the sparking plug three holes (5) may have a diameter greater than three holes (5) on the other side of the axle. The diameter of the streaming holes (5, 6 and7). and their number are chosen so that regarding the internal volume of the sparking plug cylinder (17), suitably long for the engine combustion chamber ignition gas streams are obtained. Inside the housing (2) of the sparking plug, at the bottom (17) of the sparking plug cylinder, a flange (4) has been designed. The distance between the flange £4} and the central electrode 0} is greater than the gap between the electrode 0} and the bottom part (11^*) of the sparking plug, so as not to disrupt the proper ignition, which should be located between the electrode Q) and the bottom part (11) of the sparking plug. In addition to that the sparking plug is characterized by two options of production, i.e. it can be made with non-insulated central electrode (3) whose end protrudes inside the cylinder (17) of the sparking plug, and the isolated central electrode £3} whilst the insulation may consist of a separate ceramic sleeve (8} glued to the sparking plug insulator, or the isolation may be a single element integrated (9) with the isolator (1). Height of the sparking plug cylinder (17) may not be too large to make the load combustion process inside the sparking plug proceed appropriately quickly.

In version two the sparking plug according to the invention contains a solid housing 2, which is an electric and thermal conductor. In its interior recess, a gas-proof, ceramic insulator 1 is located with central electrode 3, whose protruding end is located inside a cylinder J/7 of the sparking plug. The lower part of the sparking plug housing 2 creates a truncated cone whilst the side streaming holes 5 of the sparking plug are designed radially around the sparking plug on the flange of the cone and the streaming holes 5 are angled towards the vertical axis of the sparking plug at 45° to 90° Depending on the engine which the sparking plug is to be used with and which is closely linked with the shape of the combustion chamber, the relevant inclination of streaming holes 5 and 7 is used. At least two radially spaced streaming holes 5 are arranged on the circumference of the sparking plug cone jacket, hi addition to that, the sparking plug may have a single vertical streaming hole 6 in the bottom part JJ_. of the sparking plug designed under the sparking plug electrode 3, and at least two pieces of radially spaced streaming holes 7, designed in the bottom part JJ_. of the sparking plug and inclined towards the vertical axis of the sparking plug at the angle of 15° do 45°. In the sparking plug according to the invention the asymmetry of the lateral diameter of the streaming holes 5 can be applied. And so as far as six streaming holes 5 spaced each 60° are concerned, at one side of the axis of the sparking plug three holes 5 may have a diameter greater than three holes 5 on the other side of the axle. The diameter of the streaming holes5, 6 and 7. and their number are chosen so that regarding the internal volume of the sparking plug cylinder, suitably long for the engine combustion cylinder J/7 ignition gas streams are obtained. Inside the housing 2 of the sparking plug, at the bottom of the sparking plug cylinder J/7, a flange 4 has been designed. The distance between the flange 4 and the central electrode 3_ is greater than the gap between the electrode 2 and the bottom part JJ, of the sparking plug, so as not to disrupt the proper ignition, which should be located between the electrode 2 and the bottom part JJ_. of the sparking plug, hi addition to that the sparking plug is characterized by two options of production, i.e. it can be made with non- insulated central electrode whose end protrudes inside the cylinder J_7 of the sparking plug, and with the isolated central electrode 2 whilst the insulation may consist of a separate ceramic sleeve £ glued to the sparking plug insulator i, or the isolation may be a single element integrated 9 with the isolator L Height of the sparking plug cylinder J/7 may not be too large to make the load combustion process inside the sparking plug proceed appropriately quickly.

In version three the sparking plug according to the invention contains a solid housing 2, which is an electric and thermal conductor. In its interior recess, a gas-proof, ceramic insulator I is located with central electrode 3, whose protruding end is located inside a cylinder J/7 of the sparking plug. The lower part of the sparking plug housing 2 creates a truncated cone whilst the side streaming holes 5 of the sparking plug are designed radially around the sparking plug on the flange of the cone and the streaming holes 5 are angled towards the vertical axis of the sparking plug at 45° to 90°. Depending on the engine which the sparking plug is to be used with and which is closely linked with the shape of the combustion chamber, the relevant inclination of streaming holes 5 is used. At least two radially spaced streaming holes 5 are arranged on the circumference of the sparking plug cone jacket, hi addition to that, the sparking plug may have a single vertical streaming hole 13 and 16 in the mass electrode Jj) of the sparking plug designed coaxially with the sparking plug electrode 3 and integrated with the bottom part ϋ of the sparking plug. The mass electrode K) is integrated with the housing 2 of the sparking plug or is a separate element 15 permanently combined with the housing 2 of the sparking plug. The streaming sparking plug according to this variant has been designed so that the initiation of spark ignition in the cylinder 1/7 is located in the central part of the spark chamber. The streaming sparking plug according to this variant has been designed so that the initiation of the ignition inside the cylinder J/7 of the sparking plug is located in the central part of the sparking plug cylinder J/7, whilst the streaming holes 5 are positioned so that flames spreading from the central electrode inside the sparking plug cylinder J/7 cover the shortest possible way to the streaming holes 5 of the sparking plug. In addition to that, to shorten the time the flame reaches the streaming holes 5 and thus hasten the moment of initiation of ejecting hot streams into the combustion chamber of the engine, a flange J/2 inside the sparking plug has be used, which can occur in two variants, i.e. as a single part of the housing 2 homogeneous with the housing 2, or as a ring 14 embedded cold in the housing 2 or press assembled inside the housing 2. The distance between the flange 12 and 14 and the central electrode 3 is greater than the gap between the central electrode 3 and the mass electrode K) and 15, so as not to disrupt the proper ignition, which should be located between the central electrode 2 and the mass electrode 10 and 15. In the sparking plug according to the invention the asymmetry of the lateral diameter of the streaming holes can be applied. And so the as far as six streaming holes 5 spaced each 60° are concerned, at one side of the axis of the sparking plug three holes 5_ may have a diameter greater than three holes 5_ on the other side of the axle. The diameter of the streaming holes 5, 13 and 16, and their number are chosen so that regarding the internal volume of the sparking plug cylinder 17, suitably long for the engine combustion chamber ignition gas streams are obtained. In addition to that the sparking plug is characterized by two options of production, i.e. it can be made with non-insulated central electrode 2 whose end protrudes inside the cylinder J/7 of the sparking plug, and the isolated central electrode 3 whilst the insulation may consist of a separate ceramic sleeve 8 glued to the sparking plug insulator 1, or the isolation may be a single element integrated with the isolator. The streaming sparking plug according to this variant is characterized by a faster time of load total combustion inside the sparking plug cylinder 1/7, which as a result makes the combustion of fuel-air mixture inside the combustion chamber of the engine is even faster.
