Main Dimension and Dry Masses

Main dimensions stated in this catalog are given in mm, for guidance only.
Dismantling height:
H1: Normal vertical lift
H2: Vertical lift between cylinder cover studs

The masses are stated for engines with standard turbocharger,
a standard turning wheel and can vary up to 10% depending
on the design and options chosen such as moment compensators,
tuning wheel, etc.



Engine Power

The engine power figures in the catalog remain valid up to "tropical conditions" at sea level, i.e. :

  • Blower inlet temperature : 45 °C
  • Sea water inlet temperature : 32 °C
  • Atmospheric pressure : 1,000 hPa

Specific Fuel Oil Consumption

The SFOC figures stated in this catalog are based on the following condition.(ISO 3046/1-1995)
Tolerance margin : refer the below "Emission Control"

  • Fuel oil lower calorific value : 42,700 kJ/kg
  • Blower inlet temperature : 25 °C
  • Charger air coolant temperature : 25 °C
  • Atmospheric pressure : 1,000 hPa

Emission Control

All engines in this catalog has option of modifying and adjusting to comply with the Regulation 13 of Annex VI-Regulation for Prevention of Air Pollution from ships, of MARPOL 73/78.
The fuel oil consumption has described the value when the engine is adjusted to IMO NOx exhaust emission regulation. And, the fuel oil consumption tolerance margin applies "+3%" that has been used so far.
