Operating Ranges Wärtsilä 50DF Product Guide Fig 2-1 Operating field for CP-propeller, 975 kW/cyl, rated speed 514 rpm Remarks: The maximum output may have to be reduced depending on gas properties and gas pressure, refer to section "Derating of output in gas mode". The permissible output will in such case be reduced with same percentage at all revolution speeds.
  • Page 17 Wärtsilä 50DF Product Guide 2. Operating Ranges The load should always be applied gradually in normal operation. Acceptable load increments are smaller in gas mode than in diesel mode and also smaller at high load, which must be taken into account in applications with sudden load changes. The time between load increments must be such that the maximum loading rate is not exceeded.

For continuous operation without reduction in the rated output, the gas used as main fuel in gas operating mode has to fulfill the below mentioned quality requirements.
  • Page 60 6. Fuel System Wärtsilä 50DF Product Guide The distillate grades mentioned above can be described as follows: ● DMX: A fuel which is suitable for use at ambient temperatures down to -15°C without heating the fuel. Especially in merchant marine applications its use is restricted to lifeboat engines and certain emergency equipment due to the reduced flash point.
  • Page 61 Wärtsilä 50DF Product Guide 6. Fuel System It shall be ensured that the pour point is suitable for the equipment on board, especially if the ship operates in cold climates.

  • Page 68 6. Fuel System Wärtsilä 50DF Product Guide When operating the engine in gas mode, the gas is injected through gas admission valves into the inlet channel of each cylinder. The gas is mixed with the combustion air immediately upstream of the inlet valve in the cylinder head. Since the gas valve is timed independently of the inlet valve, scavenging of the cylinder is possible without risk that unburned gas is escaping directly from the inlet to the exhaust.

So far, the North American ECA and the US Caribbean Sea ECA have been defined and will be effective for marine diesel engines installed in ships constructed on or after 1.1.2016.
  • Page 174 13. Exhaust Emissions Wärtsilä 50DF Product Guide The IMO Tier 3 NO emission level corresponds to an 80% reduction from the IMO Tier 2 NOx emission standard. The reduction can be reached by applying a secondary exhaust gas emission control system. A Selective Catalytic Reduction (SCR) system is an efficient way for diesel engines to reach the NOx reduction needed for the IMO Tier 3 standard.
