Non-visible smoke technology for extremely high-speed 4MW class 20FX diesel engine during ship transient operation

Since developing an original diesel engine for marine propulsion in 1919, Niigata Power Systems has developed and manufactured many diesel engines, gas engines, gas turbines, and Z-PELLER propulsion system. These products have contributed to society as the key hardware of power generation and cogeneration, and engines for marine propulsion. In recent years, a high efficiency hybrid propulsion system for tugboats and a low-pollution, high efficiency dual-fuel engine for marine propulsion have been developed to protect the sea environment, which are being launched into the market.
