Working of Main Engine in Ship #marine #engine #2stroke

Even with a wide variety of advantages that 4 stroke engine offers like the compact size of the plant, much more RPM or speed etc, a 2 stroke engine outshines with few but vital advantages. This video explains the working of Maine being in ship which is usually 2 stroke engines.

Some important properties of 2 stroke engine are:

Fuel Selection: The fuel prices have gone sky high and better grade fuel is adding higher costs to vessel operation. A two stroke engine can burn low grade fuel oil and hence reduce running cost of the ship.

Efficiency: The thermal and engine efficiency of 2 stroke engine is much better than that of a 4 stroke engine.

Power: Most of the 2 stroke engines are now large stroke engines that produce more power. Hence they have high power to weight ration as compare to 4 stroke engine.

More Cargo: Ship can carry more weight and hence more cargo with 2 stroke engines because of high power to weight ratio.

Reliability: Two stroke engines are more reliable in operation as compare to 4 stroke engine.

Less Maintenance: The maintenance requirement of two stroke engine is much lesser than 4 stroke engine.

Direction control: Direct starting and reversing is easier with two stroke engine.

No reduction attachments: As two stroke engines are low speed engine, there are no requirement of reduction gear or speed reduction arrangement as required for high speed four stroke engine.

thank for this important video, but I've got a quastion, tell me please I wached a video about 2 strokes marine engine but without exhaust valve at all, there is exhaust port is used. Is this a different construction of engines ?

"Air fuel mixture"....utter bollocks, the fuel is introduced to the cylinder through one or more fuel valves, a few degrees before TDC. If you are goi g to try to explain something, understand it first
