1892Diesel patents compression ignitionNo spark requiredRudolf Diesel files a patent for an engine that compresses air so violently that injected fuel ignites from the heat alone. His stated aim is efficiency — he wants to give small workshops an engine that can compete with the great steam plants. The result is the most thermally efficient engine type ever built, and the workhorse of every ship, lorry and locomotive of the following century.
