Specifications:
The 6W105S Auxiliary Diesel Engine is designed for marine applications, featuring a 6-cylinder configuration with a bore and stroke of 105 x 130 mm and a total displacement of 6.7 liters. The engine rotates counterclockwise and has an idle speed of 650 RPM. It includes a SAE 3 flywheel and a SAE 11.5" flywheel housing.

Performance and Emissions:
The engine offers two power ratings: 125 kWm (170 HP) at 1500 RPM with a fuel consumption of 197 g/kWh and 29 l/h, and 144 kWm (196 HP) at 1800 RPM with a fuel consumption of 196 g/kWh and 33 l/h. Both ratings comply with IMO Tier II emissions standards.

Power Class Definition:
The engine is classified under Prime Power (PRP), allowing for unrestricted running time with a full load operation of 500 hours per year and load variation at 75% of rated power. It can handle a 10% overload for 1 hour every 12 hours.

Design and Durability:
Baudouin's engine design emphasizes marine power, efficiency, and reliability. It features individual cylinder heads for easy maintenance and is constructed with durable materials for long-term reliability.

Reference Conditions:
The engine operates under ambient conditions of 25°C (77°F) and 100 kPa barometric pressure, with a relative humidity of 30%. It can withstand ambient temperatures up to 45°C (113°F) and raw water temperatures up to 32°C (90°F) without power derating.

Fuel and Cooling Systems:
The engine uses fuel oil with a relative density of 0.840 ± 0.005 and a lower calorific power of 42,700 kJ/kg. It features an integrated fresh water expansion tank, a gear-driven centrifugal raw water pump, and a high-efficiency tubular heat exchanger.

Lubrication and Fuel Systems:
The lubrication system includes full flow lube oil filters and a fresh water-cooled lube oil heat exchanger. The fuel system is mechanical injection with a duplex type fuel oil filter and an external fuel pre-filter with a water separator.

Intake Air and Exhaust System:
The engine is equipped with a dry single-stage turbocharger.

Electrical System:
The electrical system operates at 24V DC and includes an electrical starter and a 55A battery charger.

Optional and Standard Equipment:
Optional equipment includes a keel cooling configuration, wet exhaust, and elastic pads. The engine's dimensions are 1362 mm total length and 1243 mm from the flywheel, with a dry weight of 780 kg.
