Which is the Most Efficient Ship Engine in the World?

27 June 2022

Over the past few years, rapid innovation in marine propulsion has occurred as a direct result of the growing need for ships that are both reliable and cost-effective to operate. As nations’ stocks of natural resources and consumer products run short, they are becoming more reliant on a dependable transportation industry to facilitate international commerce.

Consequently, new marine propulsion engines have been developed over the past several years that are designed to be more powerful and...

Watch: Ship’s Main Engine Exhaust Valve Working

31 October 2019

The ship’s main engine produces power to propel a mega-ship at sea. The power is generated inside the cylinder liner, where the fuel is compressed and burnt.

The power produced inside the cylinder is then transferred to the propeller via connecting rod and crankshaft.

No engine is 100% efficient and the ship engine will also have some waste energy while doing this work. This waste energy will be in the form of heat and exhaust.

The heat of the engine is taken care of by the jacket cooling...

How Ship’s Engine Works?

22 November 2018

Marine engines on ships are responsible for propulsion of the vessel from one port to another. Whether it’s of a small ship plying in the coastal areas or of a massive one voyaging international waters, a marine engine of either 4-stroke or 2-stroke is fitted onboard ship for the propulsion purpose.

The marine engines are heat engines used for converting heat, which is generated by burning fuel, into useful work, i.e. developing thermal energy and transforming it into mechanical energy. The...
