How Does a Spark Plug Work?

how does a spark plug work

If you’ve ever wondered how a spark plug works, you’re not alone.

Most people are curious, and rightfully so. After all, the device was invented over a century ago. This article will explain the basic process involved in spark plug ignition. After all, a spark plug is one of the most important parts of a vehicle and understanding it can help you drive a better car. And, it’s easy to understand how a spark plug works – just follow the simple steps below.

To ignite a compressed air-fuel mixture, the spark plug contains two electrodes: one is insulated, and the other is grounded. The center electrode has a gap, called the spark gap, which exposes an electric charge that produces a spark that burns the air-fuel mixture inside the combustion chamber. During the combustion process, a high voltage is applied to the spark plug and ignites the gas and air.

The two types of spark plugs are classified by their temperature range. One type is hot, while the other is cold. A hot plug operates at a higher temperature than a cold one, which helps it burn off carbon deposits and oil. Both types are good for a car, but which one is right for you? It depends on the kind of engine you have and the type of combustion. Hot plugs are best for vehicles that require higher temperatures and cold plugs are best for cars that need to be run for long periods.
