Engine technology: first patents for Daimler

Date:
16 December 1883
Description:
Gottlieb Daimler takes out patents to protect first the "gas engine with hot tube ignition" and, a week later, the "regulation of engine speed by exhaust valve control". The two patents, registered on 4 and 27 August respectively under German patent nos. DRP 28 022 and DRP 28 243, provide the basis for the world’s first high-speed combustion engine.
