ENGINE CHARACTERISTICS
  • Performance: The L23 / 30H is a four-stroke in-line engine with a minimum of 5 and a maximum of 8 cylinders. The output power range ranges from 650 kW to 1,280 kW.
  • Compact dimensions: 5.5 to 7 meters long, 1.6 meters wide and 2.3 to 2.8 meters high (depending on the number of cylinders), and a dry weight of 18.0 to 24.5 tons, makes L 23 / 30H compact motor. The height of the motor during disassembly is very small, so it is suitable in areas where the height is limited.
  • Economy: The L23 / 30H is designed to achieve optimal performance in heavy fuel oil (HFO) consumption. Consumption of lubricating oil is minimal.
  • Long period between two overhauls: with 16,000 hour intervals between two overhauls and regular short daily maintenance, the L23 / 30H has very low maintenance requirements.
  • Extensive monitoring and control system: all systems have built-in thermometers and manometers that allow alarm systems to be triggered. The engine contains standard shut-off functions in case of excessive speed, high cooling water temperature and low lubricating oil pressure.
