Another big advantage is, two stroke is a low RPM engine, if the output power
is too big to build a high efficiency transmission, such as marine diesel ( >
10,000hp, need direct drive, rpm ~ 50 only), two stroke can direct drive
without transmission.
Most big two strokes have very complicated turbo system, it is even more
complicate than 4 stroke
