Do you know what spark plugs are used for? Do you know how important they are? Well they are a very important part of your new or used car or truck. They must be properly working for your vehicle to be working.
A spark plug is an electrical device that fits into the cylinder head of some internal combustion engines and ignites compressed fuels such as aerosol gasoline, ethanol, and liquefied petroleum gas by means of an electric spark. – Wikipedia
Ok… So why are these funny looking things so important?
In a gasoline engine the importance of good sparkplugscannot be denied. The electrical arc between the electrode and the ground strap is like a miniature bolt of lightning that ignites the air fuel mixture and in turn generates the power that drives the wheels.
These miniature lightning bolts are commonly called sparkplug firing by most mechanics. If the sparkplug doesn’t fire, the engine doesn’t start. When diagnosing a no start condition some mechanics will say the reason the engine won’t start is because there is no fire.
It is the ignition system that produces the electrical energy that fires the plug. Spark also must be maintained long enough to allow complete combustion of the air fuel mixture in the cylinder. The ignition system then has to deliver this electrical energy to each sparkplug at the right time. – Online Auto Repair
Can you now understand why it is so important to have good spark plugs? Bad spark plugs = car can’t/may not start. When you come to visit your Fort Worth chevy dealer for a tune-up make sure you ask if they will be replacing the spark plugs. Feel free to ask me any questions.
