Rudolf Diesel, a German engineer, applied for a patent in Berlin in 1892 for his compression-ignition engine. This application covered the theoretical basis for an internal combustion engine where fuel ignites due to high air temperature from mechanical compression, distinct from spark-ignition engines. The event marks the formal legal protection of Diesel's concept before its practical realization.

Background and detail
Background. Rudolf Diesel moved to Berlin in 1890 to manage research and development. By 1892, after years of theoretical work, he considered his heat engine theory complete. The engine concept relied on compression ignition, where air temperature rises sufficiently to ignite fuel without spark plugs, contrasting with existing spark-ignition engines.
Theoretical Basis. The patent application described a method for converting heat into work using compression ignition. Diesel's theory posited that highly compressed hot air could ignite fuel, allowing higher compression ratios than spark-ignition engines. This theoretical framework was the foundation for the subsequent patent filings and practical development.
