Donát Bánki (born as Donát Lőwinger, 6 June 1859 – 1 August 1922)was a Hungarian mechanical engineer and inventor of Jewish heritage. In 1893 he invented the carburetor for the stationary engine, together with János Csonka (known as the Bánki-Csonka engine). The invention is often, incorrectly credited to the German Wilhelm Maybach, who submitted his patent half a year after Bánki and Csonka. Bánki also greatly contributed to the design of compressors for combustion engines. In 1898, Donát Bánki invented the high-compression engine with a dual carburetor, an evaporation method used ever since.
