Umschlag Already early Rudolf Diesel (1858 - 1913) was
interested in engines. In his youth he was fascinated by the
engines of Lenoir and the steam engines that were usual at his
time. During his study he learned of his teacher, professor
Linde, a famous inventor, that the thermal engine could reach by
far a better performance. He referred to the young Frenchman
Sadi Carnot (1796 - 1832), who discovered the Carnot' cyclic
process, a physical principle that describes the ideal process
of the burn in an engine (read more about it in the physics
section). Diesel was pursued from now on by the thought to build
such an engine. 1890, Diesel had the crucial idea, how the
cumbustion process could be improved: The engine takes in just
air, which is to be compressed now to a pressure of about 200
bar. At this point, heavy fuel (such as crude oil or petroleum)
gets injected by an injector in the air that is heated up
because of the huge pressure. The high them
