Straight-10 engine


A straight-10 engine or inline-10 engine is a ten-cylinder internal combustion engine with all ten cylinders mounted in a straight line along the crankcase. A straight-10 is a very long engine for its displacement, and as a result, has never been fitted to an automobile.

Marine use

Large ten-cylinder engines are common on large ships, such as container ships. The MAN B&W 10K90MC-C is an example of such an engine, and it is capable of developing a maximum power output of at a speed of 104 revolutions per minute. Like the vast majority of marine diesel engines, it is capable of running on diesel or heavy fuel oil, the latter of which is used most often.

Railway and stationary use

Ten-cylinder two-stroke inline engines were widely used in USSR, mostly on diesel locomotives and as back-up power sources in Soviet military. Most known engines are:
These engines produce very distinct "two-stroke" sound and are famous for the smoke they produce at full load.
