This video explains how large marine two stroke diesel engines work. We look at all of the main parts associated with the engine, how it works, and some of its typical characteristics e.g. fuel consumption, number of cylinders, weight of engine, weight of piston, rpm etc. Watch the video by saVRee for more info:

Two-stroke internal combustion engines are simpler mechanically than four-stroke engines, but more complex in thermodynamic and aerodynamic processes, according to SAE definitions. In a two-stroke engine, the four “cycles” of internal combustion engine operation intake, compression, ignition, exhaust occur in one revolution—360° of rotation—whereas in a four-stroke engine these occur in two complete revolutions—720° of rotation.


In a two-stroke engine, more than one function occurs at any given time during the engine’s operation.Intake begins when the piston is near the bottom dead center (BDC). Air is admitted to the cylinder through ports in the cylinder wall (there are no intake valves). All two-stroke diesel engines require artificial aspiration to operate, and will either use a mechanically driven blower or a turbo-compressor to charge the cylinder with air./wikipedia
