HHI EXTENDS DUAL-FUEL HIMSEN RANGE

摘要

The H54DFV engine has been designed with a 540mm bore and 600mm stroke at 6oorpm and has a maximum output of 26,400 kW. The company also announced that the new engine would be offered in both single-stage and two-stage turbocharger configurations. Development work on the H54DFV has been implemented since January 2015, and type approval testing is provisionally foreseen for Q4 2019. Marketing would start shortly thereafter, with a view to delivering the first production engine in 2021. As the latest expression of HHI's sustained, vigorous investment in engine technology, the engine will feature dual valve timing system with extreme Miller cycle that is claimed to greatly limit NOx emissions as well as offering low noise and vibrations. The maximum cylinder pressure has been increased by around 30% compared with previous models.
