High Operation Capable Marine Dual Fuel Engine with LNG

抄録

  Niigata Power Systems has been developing the gas engine for about 30 years as one of the best matched products which satisfies the trend of social requirements, such as an environmental preservation and fuel economy, and an electrical demand in industrial field.

  Niigata developed new gas engine for marine which is called dual fuel engine used two-type of fuel, oil and gas.

  The marine dual fuel engine was designed through diesel design experience and micro pilot technology for diesel mode operation and gas mode operation respectively. Niigata developed the propeller direct drive type dual fuel engine which can meet the desired load operation characteristics coming from the tugboat which works in harbor without generating abnormal combustion such as a knock, with original combustion technology.

  Sudden acceleration torque and slowdown torque are required of a tugboat at the time of navigation of a large-sized ship.

  Moreover, Niigata Dual fuel engine meets NOx emission level in IMO TierⅡ and TierⅢ at diesel operation and gas operation respectively. This performance can be accepted in ECA area.
