Compared to the best existing engines (around 15% efficiency), what range of thermal efficiency did Diesel's engine push past?

Answer

Past 30 percent

The refined Diesel engine offered an efficiency advantage by pushing thermal efficiency past 30 percent, with later iterations nearing 40 percent, dramatically reducing fuel waste.
