X62DF-P-1.0

Fuel flexibility for LPG and ammonia carriers

X-DF-P engines deliver optionality allowing to LPG/ammonia carrier operators to harmonise their choice of trade with their use of fuel.

Based on the same platform and injection concept as the X-DF-A ammonia-fuelled engine, the X-DF-P can be installed ready to use LPG, then be prepared to run on ammonia with only a minor modification.

The X62DF-P-1.0 has a bore size of 620mm and is available in five- to eight-cylinder configurations. It delivers a power range from 7,950 to 23,200kW at 77-103 rpm.
