After the congress, Gürsel issued his order to build a prototype engine and car meeting the requirements of the country.

A prototype engine was under construction in 1968.

Cooney had spent the day working with a team of engineers, connecting the prototype engine to the ship's systems.

His first prototype engines were built in 1886.

All prototype engines from V-02 to V-14 were essentially used for experimental and measurements runs.

The prototype engines were run for extended periods of time before committing to tooling production.

The prototype engine first ran in November 1948.

Karatek himself had been working with Serevan on a prototype engine.

He was proud of this vessel; she had held together when everyone else said she would fail under the prototype engine.

Only three prototype engines were built between 1931 and 1938, each of them in a different design.
