Commercial Propulsion Engines

3516C IMO II

The 3516C propulsion engine is available with a wide range of ratings that meet IMO II regulations without any additional aftertreatment. These engines provide efficient operation with electronic governing, cold mode start strategy, and programmable low idle to minimize fuel consumption. The 3516C engine also incorporates a closed crankcase ventilation system to lower emissions.
