At the time, lightweight, high-speed engines were still in the experimental phase and no existing engine was suitable for submarine electric drive.

Because of the additional weight of these pistons, they are not used for high-speed engines.

This means that high-speed engines need to be made of materials that can survive extremely high temperatures.

On high-speed engines the plunger pumps are together in one unit.

As of 2008, most high-speed engines have direct injection.

Diesel technology had improved, making small-capacity high-speed engines practical.

Its purpose was the construction of small, high-speed engines for use on land, water, and air transport.

Now during the '60s, the auto industry became enamored of short-stroke, high-speed engines for their compactness and performance.

Wolfgang heard the whine of high-speed engines and looked up.

Such governors would become significant around 1900 with the development of the high-speed engine, where they were used to control speed precisely.
