The birth of gasoline engines traces back to Nikolaus Otto's invention of the first practical four-stroke internal combustion engine in 1876. Otto's engine, employing a spark plug for ignition, laid the foundation for modern gasoline engines. Gasoline emerged as the preferred fuel due to its energy density and availability, driving rapid development in the automotive industry by engineers like Daimler and Benz.

Early challenges such as overheating and reliability were gradually overcome, leading to the widespread adoption of gasoline engines across various industries. These engines revolutionized transportation, manufacturing, and agriculture, contributing to societal transformations worldwide. Despite their enduring legacy, concerns about air pollution and greenhouse gas emissions underscore the need for cleaner alternatives, spurring ongoing efforts in research and development.
