Rudolf Diesel builds his first fully successful engine in 1897.

Diesel understands thermodynamics and the theoretical and practical constraints on fuel efficiency.

He knows that as much as ninety percent of the energy available in the fuel is wasted in a steam engine.

His work in engine design is driven by the goal of much higher efficiency ratios.

In his engine, fuel is injected at the end of compression and the fuel is ignited by the high temperature resulting from compression.

From 1893 to 1897, Heinrich von Buz, director of MAN AG in Augsburg, has given Diesel the opportunity to test and develop his ideas.
