2. Ignition coil - Wikipedia

   en.wikipedia.org/wiki/Ignition_coil

   An ignition coil is used in the ignition system of a spark-ignition engine to transform the battery voltage to the much higher voltages required to operate the spark plug(s). The spark plugs then use this burst of high-voltage electricity to ignite the air-fuel mixture. The ignition coil is constructed of two sets of coils wound around an iron ...

3. Wasted spark system - Wikipedia

   en.wikipedia.org/wiki/Wasted_spark_system

   Ignition system of a flat-twin Citroën 2CV. A wasted spark system is a type of ignition system used in some four-stroke cycle internal combustion engines.In a wasted spark system, the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke.

4. Eddy-current testing - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_testing

   Eddy current testing (ECT) as a technique for testing finds its roots in electromagnetism. Eddy currents were first observed by François Arago in 1824, but French physicist Léon Foucault is credited with discovering them in 1855. ECT began largely as a result of the English scientist Michael Faraday's discovery of electromagnetic induction in ...

5. Toyota Corolla (E120) - Wikipedia

   en.wikipedia.org/wiki/Toyota_Corolla_(E120)

   This was the first generation of the Corolla to be available in Mexico, and was offered in 3 trim levels: the base CE, the mid-range LE and S, the latter the only trim to offer a manual transmission. The base CE or "Classic Edition" trim came standard with manual windows and locks, but was available with optional power windows and locks.

6. Electromagnetic testing - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_testing

   If the test is set up properly, a defect inside the test object creates a measurable response. The term "electromagnetic testing" is often intended to mean simply eddy-current testing (ECT). However, with an expanding number of electromagnetic and magnetic test methods, "electromagnetic testing" is more often used to mean the whole class of ...

7. Coiled tubing - Wikipedia

   en.wikipedia.org/wiki/Coiled_tubing

   This component contains the mechanism to push and pull the coil in and out of the hole. An injector head has a curved guide beam on top called a gooseneck which guides the coil into the injector body. Below the injector is the stripper, which contains rubber pack off elements providing a seal around the tubing to isolate the well's pressure.
