“Spark Plugs ”

Most vehicles today use either combustion or electric engines to power the vehicle. Today we will be looking at combustion engines specifically those that use spark plugs. The spark plug is a small device but performs a crucial role. In this week’s blog, we will look at what a spark plug is, its functionality, and how to spot faulty spark plugs.

The spark plug was first invented in 1839 by Edmond Berger. In 1902, Gottlob Honold, an engineer working for Robert Bosch, patented the first commercially successful spark plug. Spark plugs are small electrical devices that feature an insulated electrode in the center. This device is placed or plugged into the engine's cylinder head and attached to the ignition coil. In cooperation, these components create a spark. This spark ignites the gasoline in the engine that was sucked in during the intake phase along with oxygen then compressed towards the head. The fuel ignition creates an explosion that pushes the piston away, creating power that the car can use. Without the spark plug the fuel will not explode leading to no power being produced by that piston in the engine.

Spark plugs should last about 30,000 to 50,000 miles but can become worn out and break. Rough idling, reduced fuel efficiency, difficulty starting, and engine misfiring are all signs that at least one of your spark plugs needs to be replaced. Your check engine light may also come on. To alleviate the problem locate your owner's manual or go to a trusted parts shop to determine the proper spark plugs for your vehicle. Spark plugs are something that one can fix with some tools and vehicle knowledge, but most auto repair places will be able to get you squared away as well. 

Spark plugs are small, but they are mighty and perform an important role in the functioning of your motor vehicle. Noticing spark plug failures can prevent further damage to the engine and make for a smoother and safer ride.
