Which type of diesel engines are primarily used by the Navy?

The type of diesel engines primarily used by the Navy are two-stroke engines. Two-stroke diesel engines are favored in marine applications because they offer a high power-to-weight ratio and can produce power on every revolution of the crankshaft, allowing for more efficient operation in various maritime conditions. These engines are also beneficial for their simpler design, which results in fewer moving parts compared to four-stroke engines, leading to increased reliability and reduced maintenance needs in demanding environments like naval operations.

In addition to efficiency and reliability, two-stroke engines can also be designed to run on various fuel types, contributing to their versatility in naval applications. The unique operational characteristics of two-stroke engines make them particularly suitable for the rigorous demands of naval vessels, where robustness and performance are critical.
