Who created the diesel engine?

The diesel engine was created by Rudolf Diesel, a German engineer, in the late 19th century. After working on steam engines and internal combustion engines, Diesel developed a highly efficient engine that would run on a wide range of fuels. He received a patent for his compression-ignition engine in 1892 and built the first working prototype in 1897. Diesel's engine revolutionized transportation and industrial applications and remains a vital component of modern engines used in cars, trucks, buses, ships, and other machinery.
