Technologies being used to make the ultimate ‘green’ ship – part 5

Exhaust Gas Recirculation

With this system, NOx emissions from the engine are reduced by recirculation of exhaust gas from engine cylinder with scavenge air which lowers the temperature of the combustion chamber. Some part of the exhaust air is re-circulated and added to scavenge air in the engine which reduces the oxygen content of the scavenge air along with the temperature of the combustion cylinder.  With this method NOx reduction of up to 80% can be achieved.

Water in Fuel

The addition of water in fuel just before its injection into the combustion chamber can reduce the temperature inside the cylinder liner.  An efficient system for this can result in NOx reduction of up to 30-35%.
