The predominance of diesel engines has come from improved engine efficiencies and designs compared to other forms of propulsion such as steam or gas turbines.

与蒸汽机、燃气轮机等形式的动力装置相比，无论是效率上的提高，还是设计上的进步，柴油机都体现出了一定的优势。

And, similar to Dyson, Lugg is proposing to achieve these radical efficiencies by coordinating multiple engine systems (analogous to the acceleration, inducement and entrainment of the Air Multiplier) to create optimal conditions for each stage of flight and to use the excess energy the system produces to create a plasma field to reduce drag and eliminate sonic boom.

It must rev up its export engine despite high costs and open itself up at home to new efficiencies and more investment.
