Working of Main Engine in Ship
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.
