Combining Environmentally Friendly Technologies for Marine Engines

The NOx emissions from ships engaged in international voyages are regulated by the International Maritime Organization (IMO*1) to protect the marine environment.
KHI developed K-ECOS*2 by using an optimal combination of various environmentally friendly technologies to both comply with IMO regulations for the main marine diesel engines and reduce their fuel consumption.
"K-ECOS is equipped with an exhaust gas recirculation (EGR*3) system, which reduces NOx emissions by using a lower combustion temperature. The EGR system is extremely compact as it has been integrated into the main engine.
In addition, as a turbochager cut-out operation allows one or both of two turbochargers (one large and one small) to be operated based on the operational situation even if the engine is in operation, this operation has contributed to a remarkable reduction in fuel consumption.
KHI is committed to continuing to develop technologies for providing more advanced systems that can be used with a variety of fuel types, including low-sulfur fuel.
