Introduction to Spark Plugs
Spark plugs are crucial components in internal combustion engines. They play a vital role in igniting the air - fuel mixture within the engine's combustion chamber. When an electrical current is sent through the spark plug, it creates a spark across the gap between the electrodes. This spark is powerful enough to ignite the compressed air - fuel mixture, which then releases energy to drive the engine's pistons. A high - quality spark plug can ensure efficient combustion, better fuel economy, lower emissions, and smoother engine operation. Over the years, with the development of engine technology, spark plugs have also evolved, with improvements in materials, design, and performance.
