Product catalog summary

Specifications:
The 12M55 is a common rail diesel engine with 12 cylinders arranged in a V configuration. It has a bore and stroke of 180 x 215 mm and a total displacement of 65.6 liters. The engine rotates counterclockwise with an idle speed of 600 RPM. It features a 21-inch flywheel and an SAE 00 flywheel housing.

Performance and Fuel Consumption:
The engine offers different power ratings and fuel consumption values depending on the duty cycle:

P1: 1800 kW at 1600 RPM with a fuel consumption of 188 g/kWh.
P2: 2205 kW at 1800 RPM with a fuel consumption of 189 g/kWh.
P3: 2536 kW at 1800 RPM with a fuel consumption of 187 g/kWh.

Fuel consumption tolerances are within +5% as per DIN ISO 3046-1.

Applications:
The engine is suitable for various applications based on duty cycles:

P1 Continuous Duty: Deep sea trawlers, tug boats, freighters, etc.
P2 Heavy Duty: Similar to P1 with additional applications.
P3 Intermittent Duty: Seasonal passenger vessels, fishing boats, etc.
P4 Light Duty: Private pleasure boats, fast vessels.
P5 High Performance Duty: High-speed private and multi-hull pleasure boats.

Cooling and Lubrication Systems:
The engine features a three-stage cooling circuit with a built-in HT thermostatic valve, an integrated fresh water expansion tank, and a high-efficiency plate heat exchanger. The lubrication system includes full-flow lube oil filters and a fresh water-cooled lube oil heat exchanger.

Fuel and Air Systems:
The engine uses a common-rail electronic injection system with a high-pressure pump. It includes a fresh water-cooled charge air cooler 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 55A battery alternator. It includes a standard BMS with an IV5 display.

Environmental and Operational Conditions:
The engine is designed to operate under ambient temperatures of 25°C to 45°C and raw water temperatures of 25°C to 32°C. It complies with ISO 3046/1 - 2002 standards and classification societies' maximum temperature definitions without power derating.
