Around it, in the bottom part, there are holes (6) in a radial pattern that enable easy gas flow into the cylinder (5) and outside the cylinder (5) from the inside. Height of the cylinder (5) is adjusted for the piston not to hit the cylinder (5) bottom (7) while the engine is working. Gasses getting out of the cylinder (5) interior via the radial pattern holes (6) should comprise as much area of the combustion chamber as possible.

Description

Ignition spark combustion engines sparking plug.
The subject of the invention. The subject of the invention is an ignition spark combustion engines sparking plug that is broadly applied in combustion engines used as drives of all kinds of vehicles, as well as mechanical devices.
Technical status quo. There are sparking plugs applied in spark ignition combustion engines. Single-electrode, three-electrode, or four-electrode sparking plugs are differentiated, and in order to improve their durability as well as ignition properties, they can be platinum-covered. Sparking plugs currently applied in car-industry, do not fulfil their basic goal, which is improving their air- fuel mixture combustion effectiveness as a function of crankshaft rotation angle. Let us use compare spark ignition combustion engine in reference to self-ignition engine with piezoelectric fuel injection as an example. Thus, if we assume four-stroke engines and they are characterized by the same swept capacity of 2000 cm3, as well as they are used in the same vehicles with identical air-resistance coefficient, then it turns out that while using the vehicles with constant velocity of 110 km/h, a self-ignition engine vehicle would consume 4 1 of fuel, whilst spark ignition combustion engine vehicle would consume 6.5 1 of fuel. A difference in both engines effectiveness is implied by two reasons: the first one is higher effectiveness of self-ignition engine vehicle resulting from higher compression ratio, the other which is the main reason of this differentiation, is combustion effectiveness as a function of crankshaft rotation angle.
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. Depending on the sparking plug mounting hole location in relation to the engine's cylinder, the sparking plug according to the invention is presented in two basic versions. Version one, 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 Double Over Head Camshaft [DOHC] is applied. 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 engine cylinders [SOHC]. hi version one, the sparking plug according to the invention, a sparking plug is constructed of 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, hi the bottom part, there are holes hi a radial pattern that enable easy gas flow into the cylinder and outside the cylinder from the inside. Height of the cylinder is adjusted for the piston not to hit the cylinder bottom while the engine is working. Gasses getting out of the cylinder interior via the radial pattern holes should comprise as much area of the combustion chamber as possible.
In version two, the sparking plug according to the invention, a sparking plug is constructed of a solid housing, which is an electric and thermal conductor. In its ulterior 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 hi relation to the engine's cylinder, hi 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 for the piston not to hit the cylinder bottom while the engine is working. Gasses getting out of the cylinder interior via the radial pattern holes should comprise as much area of the combustion chamber as possible.
In version one of the sparking plug according to the invention, a sparking plug is screwed into the hole selected in the engine's head needs no additional actions, whilst hi version two, due to the sparking plug's diagonal cylinder bottom and due to holes hi a radial pattern at one side of the sparking plug axis, mounting the sparking plug in the hole selected in the engine's head, requires using sparking plug markers and a mounting washer, since sparking plug correct setting takes place every 360° of the sparking plug cycle.
Air-fuel mixture combustion occurs in the following way: during the compression stroke, part of the new load, via the radial pattern holes in the sparking plug cylinder, gets into the cylinder. Then at the piston's top dead centre, with regard to spark lead angle, an electric spark is induced at the central electrode that passes between the electrode and grounded sparking plug cylinder bottom. Inside the sparking plug cylinder, a very quick process of combustion and hot gasses pressure increase occurs that with huge velocity flow out via sparking plug cylinder holes, initiating ignition within the engine's combustion chamber. The invention example. The sparking plug solution according to the invention, is presented in two example versions. Thus in the version one, a sparking plug is constructed of a solid housing 1, which is an electric and thermal conductor. In its interior recess, a gas-proof, ceramic insulator 2 is located with central electrode 3, whose protruding end 4 is located inside a cylinder 5 integrated with housing 1. Around it, in the bottom part, there are holes 6 in a radial pattern that enable easy gas flow into the cylinder 5. and outside the cylinder 5 from the inside. Height of the cylinder 5 is adjusted for the piston not to hit the cylinder 5. bottom 7 while the engine is working. Gasses getting out of the cylinder 5 interior via the radial pattern holes 6 should comprise as much area of the combustion chamber as possible.
In version two, the sparking plug according to the invention, a sparking plug is constructed of a solid housing 8, which is an electric and thermal conductor, hi its ulterior recess, a gas-proof, ceramic insulator 9 is located with central electrode 10, whose protruding end 11 is located inside a cylinder 12 integrated with housing, whose bottom 13 is located diagonally, depending on the sparking plug inclination angle in relation to the engine's cylinder. In the bottom part of the cylinder 12, at the side of the combustion chamber and at one side in relation to the sparking plug's axis, there are holes 14 in a radial pattern that enable easy gas flow into the cylinder 12 and outside the cylinder 12 from the inside. Height of the cylinder 12 is adjusted for the piston not to hit the cylinder 12 bottom 13 while the engine is working.
