What does a Spark Plug do? A Spark Plug is a key component in the Combustion process of an Internal Combustion Engine Its primary function is to ignite the compressed air-fuel mixture within the Engine's Cylinders at a precise moment. In the heart of your car, a finely-timed blast forces Pistons to plunge, spinning the Crankshaft and sparking the power surge that gets you rolling on the road. Here's a breakdown of how a Spark Plug works: Fuel and Air Intake: The Engine draws in a mixture of air and Fuel. Compression: The Piston moves upward, compressing the air-fuel mixture in the Cylinder. Spark and ignition: At the peak of compression, the Spark Plug delivers a high-voltage spark across its gap, igniting the compressed air-fuel mixture. Combustion: The burning mixture expands rapidly, pushing the Piston downwards with force. Exhaust: The Piston moves back up, expelling the burned gases from the Cylinder. This cycle repea ... read more
