NYK completes first ammonia-fueled ship engine ignition test

NYK Line, IHI Power Systems, Nihon Shipyard, Japan Engine Corporation and ClassNK announced that the world’s first ammonia-fuelled four-stroke engine has completed land tests for static ammonia combustion, to be subsequently developed for dynamic combustion with ammonia. Will be commercialized for installation in ships.

The consortium, formed in October 2021, aims to develop ships equipped with domestically produced ammonia-fuelled engines.

In April 2023, IHI Power Systems began operational tests at its Ota plant on a 280 mm diameter four-stroke ammonia-fuelled marine engine intended to be the main engine for coastal vessels (ammonia-powered tugboats or A-tugs) Have to be

Ammonia does not emit CO2 during combustion and is therefore expected to be a next-generation fuel to help combat global warming, but it is a difficult substance to handle because of its toxicity.

The tests also confirmed that dinitrogen monoxide (N2O), which has a greenhouse effect 300 times greater than carbon dioxide (CO2), and unburned ammonia were virtually zero, and that no ammonia leaked from all display devices during operation and after shutdown happened. ,

Prior to the test, NYK, IHI Power Systems, Nihon Shipyard and ClassNK held a demonstration equipment inspection and technical review meeting.
