About spark plug
Spark plug is one of the key components of the ignition system for the engine. A spark plug is designed to transmit electrical current from the ignition system to the ignition engine's combustion chamber to ignite the compressed fuel / air mixture through an electric spark while retaining the combustion pressure inside the engine. It has a shell of threaded wire, which is electrically protected from a central electrode by a porcelain insulator. A heavily insulated wire connects the central electrode which contains a resistor to an ignition coil output terminal also known as the magneto. The spark plugs metal casing is pressed into the engine's cylinder head, and thus is electrically grounded.
What is the purpose of spark plug?
Spark plugs are the vehicle's tiniest luminary. Which is tiny but extremely strong. The spark of electricity generated by the plug over a small gap yields the ignition required to start your motor. By setting the engine pistons in motion, the car starts, stays powered and produces a smooth combustion of the compressed air-fuel mix. They are designed to face the intense heat and pressure inside your cylinders and are designed to burn off fuel additive or other deposits of pollutants.
How spark plug works?
It is the different components used to produce spark plugs that are responsible for making them do their job safely. They consist of an insulated electrode in the center that is attached to a highly insulated wire that either connects to an external ignition coil or magneto circuit. That is shaping the grounded terminal at the base of the spark plug. A void in the spark lies inside the cylinder. Speaking generally. There are two types of internal combustion engines: spark-ignition engines (requires spark plugs to start combustion) and compression-ignition engines / diesel engines which compress air and then inject diesel into the hot compressed air mixture. The latter can also use glow plugs to boost the cold start functionality of the car.
