3516C IMO II

Categories: ,

Key Specifications

 

Power range

1.650-3.386 bhp (1.230-2.525 bkW)

Speed range

1.200-1.800 rpm

Emissions

IMO II

Efficiency, emissions reduced to a minimum and reliability.

All ratings of the 3516C propulsion engine meet IMO II regulations and do not require an aftertreatment system.

Among its main features we can note:

  1. electronic regulation,
  2. cold start strategy,
  3. Programmable low idle to minimize fuel consumption.

 

Finally, one of the greatest strengths of the 3516C engine is its closed crankcase ventilation system which helps reduce emissions.​
