What is the Ignition in a Car?

Starting the car seems like such a simple process that you might not give much thought to it when you turn the key. 

The ignition system is actually a complex series of moving and electric parts working together simultaneously, including the car battery, ignition switch, ignition coil, contact points, condenser, distributor, spark plugs, and ignition cables. 

All of these components work in tandem to produce a spark in the combustion chamber at exactly the right moment, igniting the mixture of petrol and air in the engine and getting the car started and moving.

Why is my Car Not Starting?

There can be a lot of conditions why your car won't start, from a simple flat battery to a faulty distributor cap. 

We can help with this handy guide. It will give you all the pointers for troubleshooting starting problems so that we can get you moving again.

What does a Spark Plug do?

Spark plugs are only fitted in petrol engines. They fit into the spark plug socket of your vehicle where they kickstart your ignition. They do this by transmitting electrical energy that ignites the mixture of fuel and air in the combustion chamber. This makes the engine start. 

There is one spark plug per cylinder. For example, a four-cylinder engine has four spark plugs with four spark plugs sockets. 

How long do Spark Plugs Last?

Spark plugs are designed for long-term use and are pretty durable so only need to replace them between every 80,000 and 100,000 miles.

What are the Signs you need to Change your Spark Plugs?

You may need to change your spark plugs if your car has problems starting or is misfiring.

What does a Glow Plug do?

Glow plugs are like spark plugs but they only are used in diesel cars due to the different ways they work. 

A glow plug operates by heating incoming fuel and air to deliver efficient fuel combustion in a diesel engine. The glow plugs light will indicate that they are warming up before you can start the engine. Fuel combustion will then start your engine using the glow plug.  Like a spark plug, each cylinder has one glow plug.

What happens when Glow Plugs Fail?

Factors you might notice if your glow plugs fail:

• Experiencing starting problems
• A misfiring engine
• Low performance of the engine
• Poor acceleration

If you notice any of these symptoms with your diesel vehicle, you should start by changing your glow plugs to see if this gets your car back up and running. We also do many other ignition system parts including ignition cable kits, distributor caps, contact breaker points, and rotor arms. For a complete overhaul of your ignition system.
