WinGD reports it has confirmed key parameters for its X-DF-A ammonia-fueled engine design after full-load testing at its Engine Research and Innovation Centre in Winterthur in Switzerland.
The performance and emission measurements deliver timely assurance as the first users prepare their vessels and auxiliary systems for ammonia fuel.
The tests confirm engine performance data that WinGD has published in its General Technical Data (GTD) software, available online, and guaranteed to customers.
Operation on ammonia achieved the same thermal efficiency as for diesel fuel, with pilot oil consumption at the targeted 5% of overall fuel consumption at full load, according to WinGD.
Emissions data was also encouraging, with ammonia emissions below 10ppm and N2O below 3ppm. NOx emissions for ammonia operation were well below those generated during diesel use.
Crucially, the low emissions were achieved without the use of exhaust gas after-treatment, allowing WinGD to confirm that no ammonia slip catalyst (ASC) will be needed to operate the engine with ammonia fuel.
“We we are the first two-stroke engine designer to demonstrate 100% ammonia operation with 5% pilot fuel consumption and such low emissions,” said Sebastian Hensel, WinGD Vice President Research & Development.
