Think of spark plugs as the tiniest bolt of lighting. Small but mighty, the spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. By putting the engine’s pistons in motion, your car can power up, stay powered up and produce a smooth burn of the compressed air-fuel mixture. Mind you, spark plugs like it hot: they withstand extreme heat and pressure within your cylinders and are built to burn off deposits from fuel additives or other contaminants.

What does it mean for you?
Well, without a spark, your car won’t start – or go anywhere. And because spark plug health is directly linked to engine performance, it stands to reason weak or bad spark plugs lead to problems, be it issues with cold-starting or misfires during acceleration. Besides – without healthy ones – your ride can’t sustain maximum power, and your vehicle can see a drop in fuel economy.
Now, nobody wants that.A spark plug is an electrical device that fits into the cylinder head of some internal combustion engines and ignites compressed aerosol gasoline by means of an electric spark. Spark plugs have an insulated centre electrode which is connected by a heavily insulated wire to an ignition coil or magneto circuit on the outside, forming, with a grounded terminal on the base of the plug, a spark gap inside the cylinder.

I am very interested in engineering courses so far i learn so many things that is related to my course which is mechanical engineering
