Compliance and Standards:
The engine complies with IMO II and EPA3 standards, with versions available for IMO III, EPA 4, and Stage V with ATS. It meets classification societies' maximum temperature definitions without power derating.

Cooling and Lubrication Systems:
The engine includes a two-stage cooling circuit with a built-in HT thermostatic valve, a high-efficiency tubular heat exchanger, and a gear-driven centrifugal fresh water pump. The lubrication system features full-flow lube oil filters and a fresh water-cooled lube oil heat exchanger.

Fuel and Air Systems:
The common-rail injection system includes a high-pressure pump and shielded high-pressure injection rail and pipes. The intake air and exhaust system features a double flow raw water-cooled intake air heat exchanger module and a high-efficiency dry turbocharger with ball bearing technology.

Electrical System:
The engine operates on a 24V DC insulated electrical system with an electrical starter and a 175A battery alternator. Optional equipment includes an external fuel pre-filter with water separator, keel cooling, wet exhaust, and more.

Environmental Conditions:
The engine's performance is specified under reference conditions of 25°C ambient temperature, 100 kPa barometric pressure, and 30% relative humidity. It can operate in ambient temperatures up to 45°C and raw water temperatures up to 32°C.
