: Today, diesel engine mechanics are considered high-tech troubleshooters. The role has evolved from purely mechanical "grease monkey" work to interpreting complex electronic diagnostics and emissions-control systems.
In the late 19th century, Rudolf Diesel , a German mechanical engineer, was obsessed with the massive waste of energy in steam engines, which were only about 10% efficient. His goal wasn't just technical; it was . He wanted to create a smaller, highly efficient "rational heat-engine" that independent craftsmen and artisans could use to compete with the giant, steam-powered industrial monopolies of the era.
