    Abstract: An ignition coil for an internal combustion engine capable of effectively preventing leakage of noise occurring due to, for example, radio waves or unpleasant sounds generated by a spark discharge is provided. When an elastic O-ring 12, which is a main part of the invention and which is made of a annular elastic resin material, is used as securing means, with a simple structure, it is possible to hold a second cap 9 (on a second electrode side) of an electric noise suppressing resistor 10 and to close a gap formed between an inner wall surface of a resistor accommodation section 4 and the second cap 9 of the electric noise suppressing resistor 10. Therefore, this ignition coil is characterized in that, after securing the electric noise suppressing resistor 10 to the resistor accommodation section 4 by using the elastic O-ring 12, even if the inside of the resistor accommodation section 4 is uniformly filled with the insulating material 5, it is possible to prevent leakage to a location below the resistor accommodation section 4 from occurring.

    Abstract: An internal combustion engine ignition coil according to the present invention includes: a central iron core 6; a primary coil 3 disposed on an outer circumference of the central iron core; a secondary coil 5 disposed on an outer circumference of the primary coil; a side iron core disposed on an outer circumference of the secondary coil; and an insulating material sealing the central iron core 6, the primary coil 3, and the secondary coil 5 on an inner side of the side iron core. A first layered silicate having a particle diameter less than a winding diameter of the secondary coil is present at a higher concentration in a vicinity of the secondary coil than that in a vicinity of the side iron core in the insulating material. A second layered silicate having a particle diameter greater than the winding diameter of the secondary coil 5 is present at a higher concentration than that of the first layered silicate between the outer circumference side of the secondary coil 5 and the side iron core. The second layered silicate has an aspect ratio of 50 or more, the aspect ratio being a ratio of a long side of a particle of the layered silicate to a thickness of the particle.

    Abstract: An ignition coil for delivering a spark-generating current to a spark plug includes a magnetically-permeable core; a primary winding disposed outward of the core; and a secondary winding radially surrounding the primary winding and inductively coupled to the primary winding, the secondary winding having a low-voltage end and a high-voltage end. The secondary winding includes a secondary winding first section proximal to the low-voltage end and having a first thickness. The secondary winding also includes a secondary winding second section proximal to the high-voltage end and having a second thickness that is less than the first thickness of the secondary winding first section.

    Abstract: An ignition apparatus includes a cylindrical core made from magnetically-permeable material and a C-shaped magnetic return path structure that is made from a stack of silicon steel laminations. A tightly controlled air gap is provided between one leg of the C-shaped structure and an end face of the core, forming a magnetic circuit having a high magnetic permeability, which overall reduces the number of primary winding turns needed, thereby reducing the amount of copper wire. In addition, the circular cross-section of the core reduces the mean length per turn (MLT) of the primary winding because the primary winding can be wound directly on the core, which in turn also reduces the MLT of the secondary winding. The reduced MLT also reduces the amount of copper wire. The structure may be replaced using a magnetically-permeable, U-shaped shield.
