Development of Dual Fuel Engine 28AHX-DF Capable of FPP Direct DriveIn order to meet stringent exhaust emission regulation for marine engine, the alternative fuel is growing in usage and popularity. In particular, the market demand of gaseous fuel as typified by natural gas is heavy thanks to its high environmental adaptability and worldwide falling prices. According to this circumstance, Niigata has recently developed the dual fuel engine 28AHX-DF with advanced transient performance and thermal efficiency. 28AHX-DF engine is developed to apply to marine engine which directly drive the fixed pitch propeller. The reason comes from the fact that the effect of greenhouse gas reduction from marine gear direct drive is larger in comparison with electric propulsion which is affected by generator efficiency. In case of the direct drive propulsion, it is difficult to ensure the sufficient air delivery and the knocking might be occurred since the engine load is changed along the propeller law. Therefore, the combustion control technology and air/fuel control technology as countermeasure for this difficulty is required. 28AHX-DF engine with superior transient performance which allows load acceptance within fifteen second or so due to high performance control technology was delivered as main engine of a tugboat in 2014 and the operation has been begun in 2015.
