The spark plug is a crucial component in the internal combustion engine of a vehicle, responsible for igniting the fuel-air mixture inside the engine’s cylinders. Its invention revolutionized the automotive industry, enabling the widespread adoption of internal combustion engines in vehicles. The spark plug’s development is a fascinating story that involves the contributions of several inventors and innovators over the years. In this article, we will delve into the history of the spark plug, exploring its evolution, key milestones, and the people behind its invention.
The Early Days of Spark Plug Development
The concept of using a spark to ignite fuel dates back to the early 19th century, when inventors began experimenting with internal combustion engines. One of the earliest known attempts at creating a spark plug was made by Samuel Morey, an American inventor, in 1826. Morey’s design used a battery and a spark-producing device to ignite a mixture of coal dust and air.
Early Spark Plug Designs
Early spark plug designs were often cumbersome and unreliable. They used a variety of materials, including copper, iron, and steel, and were prone to overheating and wear. In the mid-19th century, inventors began to experiment with more advanced materials, such as platinum and iridium, which offered improved durability and resistance to corrosion.
One of the earliest commercial spark plug designs was developed by the German engineer, Gottlieb Daimler, in the 1880s. Daimler’s spark plug used a platinum electrode and a copper core, and was designed to be used in his pioneering internal combustion engine.
Key Players in Spark Plug Development
