Page 13: Operating Ranges
Wärtsilä 46F Product Guide 2. Operating Ranges Operating Ranges Engine operating range Running below nominal speed the load must be limited according to the diagrams in this chapter in order to maintain engine operating parameters within acceptable limits. Operation in the shaded area is permitted only temporarily during transients. Minimum speed is indicated in the diagram, but project specific limitations may apply.
Page 14: Loading Capacity
2. Operating Ranges Wärtsilä 46F Product Guide Loading capacity Controlled load increase is essential for highly supercharged diesel engines, because the turbocharger needs time to accelerate before it can deliver the required amount of air. A slower loading ramp than the maximum capability of the engine permits a more even temperature distribution in engine components during transients.
Page 15: Operation At Low Load And Idling
Wärtsilä 46F Product Guide 2. Operating Ranges In normal operation the load should not be reduced from 100% to 0% in less than 15 seconds. When absolutely necessary, the load can be reduced as fast as the pitch setting system can react (overspeed due to windmilling must be considered for high speed ships).
Page 16 2. Operating Ranges Wärtsilä 46F Product Guide ● Maximum 10 minutes if the engine is to be stopped after the idling. 3 minutes idling before stop is recommended. ● Maximum 6 hours if the engine is to be loaded after the idling.
Page 17: Low Air Temperature
Wärtsilä 46F Product Guide 2. Operating Ranges rated output can be replaced by 2 times 30 minute engine operation at 70 % of the rated output. Note that shorter duration than 30 minutes is not recommended. Low air temperature The minimum inlet air temperature of 5°C applies, when the inlet air is taken from the engine room.
