Car Coil

Coil cars also referred to as steel coil cars or coil steel cars are a specialized type of rolling stock designed for the transport of coils i e rolls of sheet metal particularly steel they are considered a subtype of the gondola car though they bear little resemblance to a typical gondola.

Car coil. An ignition coil also called a spark coil is an induction coil in an automobile s ignition system that transforms the battery s voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel. The primary winding of your ignition coil is the first to receive voltage from the battery so we ll follow its lead and test the primary first. Spark timing is so critical to an engine s performance that most cars don t use points. An ignition coil is a kind of high voltage transformer.

Although manufactured to last ignition coils are not fail safe. It converts the power from your car s 12 volt battery into the thousand or so volts that the spark plugs need in order to fire and then ignite the engine s air fuel mixture. The secondary coil normally has hundreds of times more turns of wire than the primary coil. Some ignition systems will use one coil to provide the spark for all of the.

The coil is a simple device essentially a high voltage transformer made up of two coils of wire. What the coil does. Instead they use a sensor that tells the engine control unit ecu the exact position of the pistons. Current flows from the battery through the primary winding of the coil.

Find the resistance specifications for your car s primary coil winding in your repair manual. Ignition coils are an electronic engine management component that are a part of the vehicle s ignition system. The engine computer then controls a transistor that opens and closes the current to the coil. Some coils have an internal resistor while others rely on a resistor wire or an external resistor to limit the current flowing into the coil from the car s.
