12M26.3

Product catalog summary

Specifications:
The Baudouin 12M26.3 propulsion engine features a 12-cylinder V configuration with a bore and stroke of 150 mm each, resulting in a total displacement of 31.8 liters. It operates with a compression ratio of 15:1 and rotates counterclockwise. The engine is equipped with a common rail injection system and has an idle speed of 650 rpm. The flywheel and housing conform to SAE 0 and SAE 18" standards, respectively.

Performance and Fuel Consumption:
The engine offers different power ratings and fuel consumption metrics across various duty cycles:

P1: 883 kW at 1800 rpm with a fuel consumption of 200 g/kWh.
P2: 972 kW at 1800 rpm and 1030 kW at 2100 rpm, with fuel consumption ranging from 199 to 206 g/kWh.
P3: 1214 kW at 2300 rpm with a fuel consumption of 205 g/kWh.

These ratings comply with IMO and EPA standards.

Applications:
The engine is suitable for various marine applications:

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

Customer Benefits:
The engine is designed specifically for marine applications, offering low exhaust emissions, excellent fuel consumption, and high performance in heavy-duty applications.

Cooling and Lubrication Systems:
The engine features a two-stage cooling circuit with a built-in HT thermostatic valve, an integrated fresh water expansion tank, and a high-efficiency tubular 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 common-rail electronic injection system includes a high-pressure pump and shielded high-pressure injection rail. The intake air and exhaust system features a double flow raw water-cooled intake air heat exchanger module and a high-efficiency dry turbocharger.

Electrical System:
The engine operates on a 24V DC insulated electrical system with an electrical starter and a 190A battery alternator. Optional equipment includes wet exhaust, PTO elastic coupling, and different alternators.

Hybrid Package:
The hybrid package includes two units with a nominal power of 200 kW and peak power of 260 kW. The package offers full electric autonomy for 1 to 2 hours depending on the configuration, with battery packs using LFP technology.

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, with fuel oil specifications adhering to DIN ISO 3046-1 standards.
