The five-cylinder test engine in China had an output of 125 kW per cylinder at a nominal speed of 720/750 rev/min.
Finn Fjeldhøj, MDT’s head of small-bore, 4-stroke engineering, said: “The L23/30DF covers a power range of 625 – 1,200kW, which makes it particularly attractive for such ocean-going vessels as bulkers of most sizes, general cargo ships, chemical tankers, and smaller LNG-carriers, as well as ships operating in ports and near the coast. Encouragingly, shipowners around the world have already shown significant interest in the engine and we are very optimistic about its future prospects.”
The df engine was also granted a certificate for compliance with IMO Tier III regulations in gas mode without any after-treatment equipment. In addition, the engine can provide up to 110% power output in both gas and fuel modes.
