Ignition Coil Parts
After a long weekend out of town road tripping in your Nissan you are ready to get home. You are near your house but you need to get some lunch supplies at the grocery store for the next day. The previous stop you made you noticed your Nissan was having a little trouble starting when you turned it on but didn’t really pay too much attention to it. So you get all your groceries and head back to your Nissan but when you try to turn it on it won’t start. You keep trying and it won’t turn on. This indicates that there is a problem with your ignition system. One of the likely causes could be a faulty Nissan ignition coil.
The Nissan ignition coil is an induction coil that changes the battery’s low voltage to the thousands of volts needed to create an electric spark in the spark plugs in order to ignite the fuel. It will be made up of two windings, a primary and a secondary one. The primary winding has a few hundred turns of heavy wire. While the secondary winding has thousands of smaller wire that are insulated for heavy voltage. The coil is usually in a metal can or plastic case with insulated terminals for both high and low voltage connections. When the contact breaker closes a current from the battery builds up in the primary winding of the coil.
This current then makes a magnetic field in the core and in the surrounding areas of the core. The current needs to flow long enough in the field of the spark in order to make enough energy. When the current reaches its full level, the contact breaker opens. This allows the primary winding and the capacitor to form a tuned circuit. This causes a changing magnetic field in the core of the coil making a larger voltage in the secondary part of the coil. The spark must occur after the air/fuel moisture is compressed. When the spark does occur this is what lights the spark plug in order to ignite your Nissan.
In terms of different types of Nissan ignition coil replacement options there are a few. These are known as ignition coil packs, coil on plug ignition, and waste spark style ignition coils. Ignition coil packs are a group of ignition coils connected to each other providing one ignition coil per cylinder. These are controlled by a computer so distributors, points and condensers aren’t needed. A coil plug ignition (COP) has one individual ignition coil sitting on top of each individual spark plug. So no spark plug wires are needed. A waste spark style halves the number of parts in an ignition system using two spark plugs firing from one ignition coil. This is done by firing one spark the top of the compression and the other at the opposite cylinders exhaust stroke.
