Description
- 1. Field of the Invention
- The invention relates to an internal combustion engine spark ignition system. More specifically, the invention relates to a pencil ignition coil designed to be mounted to a spark plug without damaging the pencil ignition coil or the spark plug.
- 2. Description of the Related Art
- The internal combustion engine can be categorized in several ways. One such way to categorize the internal combustion engine is whether the design requires a spark to combust the fuel within cylinders of the internal combustion engine. Diesel engines do not require a spark to be generated within the cylinders thereof. Non-diesel consuming internal combustion engines do, however, require a spark to ignite the fuel within the cylinders thereof.
- With regard to non-diesel internal combustion engines the design thereof include the utilization of pencil ignition coils to operate the spark plugs. Recent developments in internal combustion engines include coils, sometimes called pencil coils, that are designed to be mounted directly to the spark plug. In addition, the pencil ignition coil is designed to primarily extend through the spark plug bore of the internal combustion engine. In other words, the pencil ignition coil is a long, thin pencil ignition coil designed to utilize the wasted space of the spark plug bore of the internal combustion engine.
- Inherent in the design of a pencil ignition coil is the requirement that the pencil ignition coil be positively mounted to the engine and electrically connected with the terminal of the spark plug. Once the spark plug has been screwed into the spark plug bore, one way to positively mount to the engine and electrically connect the pencil ignition coil to the spark plug is to friction fit the pencil ignition coil over the terminal of the spark plug. To ensure the pencil ignition coil does not disengage the spark plug during the operation of the internal combustion engine, the friction fit (or press fit) must be strong enough to withstand operational forces that might jar the pencil ignition coil from the spark plug. Creating the friction fit is problematic because the impact force used to create the friction fit by forcing the pencil ignition coil over the spark plug may cause damage to the pencil ignition coil or the spark plug. If such damage occurs, either the spark plug and/or the pencil ignition coil will have to be replaced prematurely.
- A shock absorbing assembly reduces impact forces on a terminal of a spark plug that is mounted within a bore of an internal combustion engine when a pencil ignition coil is mounted thereto. The shock absorbing assembly includes a plug cup that is fixedly secured to the terminal end of the spark plug. A case cup is movably mounted to the plug cup. The case cup includes a resistor receptacle for receiving the pencil ignition coil therein. The shock absorbing assembly also includes a cup spring that extends between the plug cup and the case cup. The cup spring absorbs the impact forces of mounting the pencil ignition coil to the terminal of the spark plug.
- Advantages of the invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein:
-
FIG. 1 is a cross-sectional side view of one embodiment of the invention mounted in a spark plug bore of an internal combustion engine; -
FIG. 2 is an electrical schematic of a pencil ignition coil and spark plug utilizing the invention; -
FIG. 3 is a sectional view of one embodiment of the invention; -
FIG. 4 is an exploded perspective view of one embodiment of the invention; -
FIG. 5 is a cross-sectional side view of a second embodiment of the invention mounted to a terminal of the spark plug; and -
FIG. 6 is a side cross-sectional view of a third embodiment of the invention. - Referring to

Thepencil ignition coil 10 includes acover 14 that extends out of theengine head 12 and provides for electrical connection to avoltage source 16 as well as being operatively connected toground 18, as is best seen inFIG. 2 . - The
pencil ignition coil 10 also includes aferromagnetic core 20 that is surrounded by a primary winding 22 and asecondary winding 24. Theprimary winding 22 is connected to thevoltage source 16 through afirst terminal 25. Thesecondary winding 24 is connected to ground on the low voltage side. Asubsequent end 26 of theprimary winding 22 is connected through asecond terminal 27 to aswitch 28 that switches between alow impedance 30 and ahigh impedance 32. Asubsequent end 34 of thesecondary winding 24 is operatively connected to aterminal 36 of aspark plug 38 through aresistor 39. Thespark plug 38 includes twoterminals gap 43. When theswitch 28 switches from thelow impedance 30 to thehigh impedance 32, a current is generated in thesecondary winding 24 forcing current to pass between the twoterminals gap 43 therebetween. This spark ignites the fuel within a cylinder 44 of theinternal combustion engine 13. - Extending between the
pencil ignition coil 10 and thespark plug 38 is a shock absorbing assembly, generally indicated at 46. Theshock absorbing assembly 46 reduces the impact forces on theterminal 36 of thespark plug 38. More specifically, thespark plug 38 is threaded within aspark plug bore 48 of theengine head 12. Thepencil ignition coil 10 must be mounted on theterminal 36 of thespark plug 38. The forces generated to secure thepencil ignition coil 10 to theterminal 36 are absorbed by theshock absorbing assembly 46 disposed therebetween. - Referring to

More specifically, thecase receiving flange 54 extends outwardly perpendicular to a side wall of thecylindrical body 52. Thecylindrical body 52 includes an angleddistal end 56 to aid theplug cup 50 as it is being inserted over theterminal 36. Depending on the design of thepencil ignition coil 10, theengine head 12 and thespark plug 38, thecase receiving flange 54 may include aterminal boss 58 extending down into thecylindrical body 52 to properly position theplug cup 50 with respect to theterminal 36. - The

Thecase cup 60 includes aresistor receptacle 62 that extends at acoil end 64 of thecase cup 60. Theresistor receptacle 62 receives theresistor 39 therein. Thecase cup 60 includes acase cylinder 66 that extends between thepencil ignition coil 10 and theplug cup 50. Thecase cylinder 66 includes alocking lip 68 that extends inwardly from thecase cylinder 66. Thelocking lip 68 engages thecase receiving flange 54 and prevents theplug cup 50 from disengaging thecase cup 60. Thelocking lip 68 defines anaperture 70 through which theplug cup 50 extends. - The
plug 50 andcase 60 cups are manufactured from a drawing operation. While these parts may be manufactured using a standard screw machine operation, the drawing operation is a more efficient way to manufacture theplug 50 andcase 60 cups without compromising performance. - The
shock absorbing assembly 46 also includes acup spring 72 that extends between theplug cup 50 and thecase cup 60. It is thecup spring 72 that absorbs the impact forces of the mounting of thepencil ignition coil 10 onto theterminal 36 of thespark plug 38. In the embodiment shown inFIG. 3 , thecup spring 72 is a compression coil spring that is fabricated from a ferromagnetic material. It is important that thecup spring 72 be fabricated from a material that conducts electricity so that thepencil ignition coil 10 can make sufficient electrical contact with thespark plug 38 to generate the appropriate spark. As may be seen fromFIG. 3 , thecase cup 60 and theplug cup 50 are coaxial. - Referring to
FIG. 4 , it can be seen that thecase cup 60, thecup spring 72 and theplug cup 50 are all coaxial with acase 74 that receives thepencil ignition coil 10 therein. Wile thecase 74 is shown to have multiple sections having different diameters, it should be appreciated by those skilled in the art that the shape of thecase 74 may vary so long as it maintains the elements therein coaxial. Aterminal clip 76 is fitted around thecylindrical body 52 of theplug cup 50 to secure theplug cup 50 to the terminal 36. In one embodiment, theterminal clip 76 includesdetents 72 that extend intoholes 79 or recesses in theplug cup 50. It should be appreciated by those skilled in the art that theterminal clip 76 may be configured in other shapes. In particular, theterminal clip 76 may be fabricated in a three-leaf combination similar to that shown in U.S. Pat. No. 6,358,071, which is hereby incorporated by reference. - Referring to
FIG. 5 , wherein like prime numerals represent elements similar to those found in the first embodiment, ashock absorbing assembly 46′ is shown secured to a terminal 36′ of aspark plug 38′. Theplug cup 50′ is designed to be received within thecase cup 60′ and thecup spring 72′. Theplug cup 50′ includes aterminal receiving cylinder 73 that extends into thecase cup 60′ and thecup spring 72′. Thecase receiving flange 54′ is designed such that it includes anangled surface 78. Theangled surface 78 engages the lockinglip 68′ of thecase cup 60′. Thecase receiving flange 54′ is opposite aterminal abutting end 80 of theplug cup 50′. Theshock absorbing assembly 46′ is designed to allow theplug cup 50′ to extend within thecase cup 60′ at an angle that is not coaxial with thecase cup 60′. This allows thepencil ignition coil 10 to be mounted within theengine head 12 at an angle with respect to theterminal 36 of thespark plug 38. - In a second alternative embodiment, wherein like double primed reference characters represent elements similar to those found in the preferred embodiment, the
shock absorbing assembly 46″ includes acomposite cup spring 72″. Thecomposite cup spring 72″ includes aprimary spring element 82 and asecondary spring element 84.

Thesecondary spring element 84 is a winding that provides secondary shock absorbing characteristics of thecomposite cup spring 72″. More importantly, thesecondary spring element 84 provides an electrical path maintaining the electrical connection between thepencil ignition coil 10 and thespark plug 38″. It may be appreciated by those skilled in the art that thesecondary spring element 84 may be replaced with another element that has minimal spring characteristics so long as the path for the electrical current between thepencil ignition coil 10 and thespark plug 38″ is maintained. - The invention has been described in an illustrative manner. It is to be understood that the terminology, which has been used, is intended to be in the nature of words of description rather than of limitation.
