The VW ignotion coil is a device that can also be referred to as a voltage amplifier since it dramatically increases the voltage of the vehicle in order to create the necessary electrical energy. The VW ignotion coil may be remotely mounted or may be placed on top of each spark plug which is called as “coil on plug” or direct ignition system. www.vdubpartsdirect.com /vw_ignitioncoil.html   (654 words)

Ignition Coil - HvWiki Ignition coils are oil-filled iron-core transformers that rely on the inductive kick effect to produce high voltages in the range of 15-50kV, depending on the internal design and how they are driven. Most ignition coil circuits tend to produce a waveform on the secondary with a very high peak voltage, although the average power is relatively low. Powering ignition coils outside the context of cars is often achieved with a 555 timer circuit triggering a power transistor that switches 12-48V through the primary, at a frequency usually between 50Hz and 200Hz. wiki.4hv.org /index.php/Ignition_Coil   (617 words)

Ignition System The secondary circuit consists of the secondary windings in the coil, the high tension lead between the distributor and the coil (commonly called the coil wire) on external coil distributors, the distributor cap, the distributor rotor, the spark plug leads and the spark plugs. The voltage from the coil secondary windings flows through the coil high-tension lead to the center of the distributor cap, where it is distributed by the rotor to one of the outer terminals in the cap. Ignition timing is the measurement, in degrees of crankshaft rotation, of the point at which the spark plugs fire in each of the cylinders. www.procarcare.com /icarumba/resourcecenter/encyclopedia/icar_resourcecenter_encyclopedia_ignition.asp   (2319 words)

Ignition System The secondary coil has a few thousand turns of small diameter wire in it because it is the one that will make the high voltage, but low current, and fire the spark plugs. When they are closed, the electricity flows from the battery to the ignition switch on the steering column, to the positive side of the primary coil, and across the points to ground. The positive side of the secondary coil attaches to the positive primary wire, and the negative side goes to the coil tower where the coil high tension wire plugs in. www.abbysenior.com /mechanics/ignition.htm   (4966 words)

Circuit for decreasing oscillatoins in the primary winding of an ignition coil of an internal combustion engine - ... Oscillations which would normally occur when the current in the primary winding of an ignition coil is limited to a predetermined value prior to ignition are suppressed by use of a feedback resistor. Specifically, the basic circuit consists of the primary winding of the ignition coil connected in series with a Darlington transistor configuration which, in turn, is connected in series with a measuring resistor, at a common point. A series circuit including the primary winding 5 of ignition coil 6, the emitter-collector circuit of a switching transistor 7, and a measuring resistor 8 is connected from supply line 4 to ground potential. www.freepatentsonline.com /4382431.html   (1463 words)

Ignition coil - Wikipedia, the free encyclopedia An ignition coil (also called a spark coil) is an induction coil in an automobile's ignition system which transforms a storage battery's 12 volts to the thousands of volts needed to spark the spark plugs. The disruptive discharge Tesla coil is an early predecessor of the "ignition coil" in the ignition system. An Oudin coil is a disruptive discharge coil. en.wikipedia.org /wiki/Ignition_coil   (401 words)

How to use an Ignition Coil An ignition coil is essentially an autotransformer with a high ratio of secondary to primary windings. When the ignition coil is connected to the battery, the inductor is 'charged' with current. However, the ignition coil still works the same way, so you should be able to use an ignition coil even from a modern car. www.sentex.net /~mwandel/cannon/sparky.html   (1228 words)

Ignition system - Wikipedia, the free encyclopedia The engine spins a magnet inside a coil, and also operates a contact breaker, interrupting the current and causing the voltage to be increased sufficiently to jump a small gap. For an ignition coil, one end of windings of both the primary and secondary are connected together. The ignition coil's secondary windings are connected to the distributor cap. en.wikipedia.org /wiki/Ignition_system   (1972 words)

ignition coil The secondary coil, connected via the distributor to the spark plugs, has many turns. The coil takes in a low voltage (usually 12 volts) from the battery and transforms it to a high voltage (about 15,000–20,000 volts) to ignite the engine. The collapsing current in the primary coil induces a current in the secondary coil, a phenomenon known as electromagnetic induction. www.tiscali.co.uk /reference/encyclopaedia/hutchinson/m0016532.html   (319 words)

Ignition Systems  A Short Course The ignition system sends an extremely high voltage to the spark plug in each cylinder when the piston is at the top of its compression stroke. The ignition coil is the component that converts the 12 volt signal into the high 20,000+ volt charge. First, it is responsible for triggering the ignition coil to generate a spark at the precise instant that it is required (which varies depending how fast the engine is turning and how much load it is under). www.familycar.com /Classroom/ignition.htm   (4392 words)

High Performance Ignition Nology PowerCore Coil Amplifier PowerCore is the perfect ignition upgrade for vehicles where the ignition coil is incorporated within the distributor, (Honda, Acura, General Motors). The coil size stays the same, but the energy that is stored in the PowerCore is supplied to the coil, resulting in added spark energy and higher possible spark voltage. For ignition systems without active current limiting and most automotive applications Model Year 1990 and older with 2.5 to 3 Ohm ignition coils. www.nology.com /power.html   (354 words)

Ignition Coils Remember, a coil, like any other metal component, expands with heat and the windings may be making contact when the coil is expanded but not when cold, or vice versa. For cylindrical (round type) coils, look for those that are fluid filled-the sloshing action of the fluid pulls heat off the windings and splashes against the case, thereby keeping the windings cool by drawing heat into the metal case. Many ignitions can show a really hot looking spark into an inexpensive unloaded gap but then fall on their face when asked to fire a real engine's plug that may be a little fuel wet, has some miles or laps on it, or even moisture. www.castensdynojet.com /ignitioncoils.htm   (2091 words)

Ignition Coil - Tech - Terms & Definitions - Hot Rod Magazine Ignition designs that use the electromagnetic field of an ignition coil to store spark energy are technically known as "Kettering" ignition systems, named after its original designer 75 years ago. The property of a coil that allows voltage to be induced is called inductance, and inductance is the principle upon which hundreds of millions of ignition systems have been built over the years. These two coils are contained in a single housing, and most racers simply refer to them as "the coil." The loops of wire that form each of the two coils inside the housing are called "turns" by electrical engineers, and the ratio of turns between the primary and secondary coils is very important. www.hotrod.com /techarticles/ignition_coil_tech   (4848 words)

Daytona Twin Tec LLC - Tech FAQ Ignition Overview Coil current is limited electronically within the module by restricting the charging time. CD ignition systems are more complex, more expensive, and take up more space than an inductive system due to the requirement for the special high voltage power supply. The older cast epoxy coils are prone to developing cracks that allow moisture infiltration resulting in premature failure from arcing between layers of the coil windings. www.daytona-twintec.com /tech_ignition.html   (3023 words)

Overboost.com - How To: Install an MSD Ignition   (Site not responding. Last check: ) First, remove the distributor cap to expose the ignition rotor; the rotor is held to the distributor with a screw, and you may have to "tap" the starter to get the screw pointing in a direction that can be reached with a screwdriver. The stock coil is held in place with two Phillips-head screws; remove them and the coil easily pulls straight out. Once the distributor cap is installed, trim the high-tension coil lead to length; strip away about 10 millimeters of insulation and crimp on the end connector. www.overboost.com /story.asp?id=265   (941 words)

POWERLABS Ignition coil drivers page! Car Ignition coils (there are other kinds, such as motorcycle and boat coils, but the ones made for automotive engines are the largest) consist of two windings: A primary and a secondary, wrapped around a core (usually multi layered silicone steel) and encapsulated in some insulating material (epoxy or oil are normally used). Both ignition coils have been fitted inside the box, and their cases are used as a common ground. The coils would hum and vibrate loudly and often the runs would have to be stopped because the oil was boiling inside them. www.powerlabs.org /igncoildrivers.htm   (929 words)

Ignition System Basics - Top Dead Center - Mustang & Fords Magazine You want to know what the ignition coil's basic job is, and how it releases that high-voltage spark in time with the engine's power cycles. Ignition points are nothing more than a simple on/off switch that allows the ignition coil (a transformer) to store and discharge thousands of volts of direct current electricity supplied by your Ford's 6- or 12-volt storage battery. Solid-state ignition systems, as their name implies, are solid state--no moving parts to wear out. www.mustangandfords.com /techarticles/mufp_0505_ignition_system_basics/top_dead_center.html   (1422 words)

Igniting Creativity - WeaponX's all new 32v Ignition Coil Upgrade Most 'coil on plug' (one coil for each spark plug) systems are actually 'coil near plug' because a short mechanical connector or spark plug wire connects the coil to the plug. The interconnect on the OEM C.N.P coils is not merely a spring. By creating an ignition coil that has weather seals and stays in the head without alternate means of retention it allows users to keep the ignition coils cooler and operating at a much more efficient level of operation. www.modularfords.com /articles/Igniting_Creativity/1.html   (4843 words)

Ignition coil connectors On vehicles with a conventional coil ignition, the distributor (distributor cap) is equipped with connectors. The spark plug connector connects the spark plug to the ignition lead and thus provides the reliable transmission of the high voltage from the ignition coil to the spark plug. In vehicles that are equipped with older ignition coils, ignition coil connectors are used. www.beru.com /english/produkte/stecker.php   (258 words)

Ignition coil invention The ignition coil is electrically connected with a spark plug to generate a spark in a combustion chamber of a cylinder of the engine. [0004] In the ignition coil, a magnetic field is generated to pass through the center core and the outer core by instantaneous electricity transmission to a primary coil. When the electricity transmission to the primary coil is stopped, an inductive magnetic field is generated to pass through the center core and the outer core in a direction opposite to the magnetic field, so that the secondary coil generates induced electromotive force (counterelectromotive force) by the inductive magnetic field. www.freshpatents.com /Ignition-coil-dt20060810ptan20060176134.php   (1087 words)

loneoceans.com - Ignition Coil An Ignition Coil is an induction coil that converts current from a car battery (12V) into the high-voltage sparks required by spark plugs in a car engine. Ignition coils are built quite well and they are almost like small versions of Pole-Pig-Transformers/Power Distribution Transformers and can handle quite large amounts of overrating and abuse. I wired the two coils in anti-parallel (the + of the first coil is connected to the - of the other coil and the arc strike between the two HV outputs.) and the result was spectacular. www.loneoceans.com /lo_main/labs/ignitioncoil   (2380 words)

Howstuffworks "How Automobile Ignition Systems Work" The coil is the device that generates the high voltages required to create a spark. The key to the coil's operation is what happens when the circuit is suddenly broken by the points.

Mercedes-Benz Ponton Ignition Coil Overview The higher voltage of these special coils (and the same remark applies to modern coils designed to replace standard coils) calls for some care in the arrangement of the high-tension wiring. The extra coil output naturally calls for more low-tension current to be dealt with by the contact-breaker points. Some makers of high voltage coils market toughened points and more robustly insulated condensers for use with their product, and these should certainly be included in any change over. www.mbzponton.org /valueadded/maintenance/ignition/coil1.htm   (686 words)

Mercedes Benz Ignition Coil, Mercedes Ignition Coil, Mercedes Ignition Coils - Euro Mercedes Parts Without this coil, it would be impossible for the spark plugs to generate the spark that will be used to ignite the compressed air-fuel mixture.
