Which key principle did Philippe Lebon patent in 1799 that later became critical for engine efficiency?
Answer
Compression of gas and air mixtures
The patent filed in 1799 introduced the revolutionary idea that the fuel-air charge needed to be compressed before it was ignited. This process allows for a significantly more forceful expansion during the power stroke. While this specific design did not result in a working engine at the time, it established the foundational principle that high-pressure combustion is necessary for effective mechanical output, a concept that would later become the standard for all modern engines.
