Product catalog summary

Overview: This document provides technical specifications and operational guidelines for MAN marine diesel engines, specifically focusing on medium-duty operation engines ranging from 265 to 809 kW (360 to 1100 hp). The engines discussed include in-line models (D 0836, D 2866, D 2876) and V-type models (D 2848, D 2840, D 2842).

Technical Specifications:

In-line Engines: These engines have 6 cylinders with bore sizes ranging from 108 to 128 mm and strokes from 125 to 166 mm. The displacement varies from 6.87 to 12.8 liters, with compression ratios between 15.0:1 and 16.0:1. The maximum output ranges from 265 kW (360 hp) to 412 kW (560 hp) at rated speeds of 2100 to 2400 rpm.
V-type Engines: These engines feature 8 to 12 cylinders with a bore of 128 mm and a stroke of 142 mm. Displacement ranges from 14.62 to 21.93 liters, with compression ratios of 13.5:1 to 15.5:1. Maximum output is between 478 kW (650 hp) and 809 kW (1100 hp) at rated speeds of 2100 to 2300 rpm.

Performance and Consumption: The engines are designed for high tractive power, rapid acceleration, and low fuel consumption. Specific fuel consumption at rated power ranges from 212 to 224 g/kWh, with fuel consumption rates between 69 to 206 l/h depending on the model.

Operational Guidelines: Medium-duty operation is defined by annual operating hours of ≤ 3000, with ≤ 50% of time at full load and an average load application of ≤ 70%. These engines are suitable for applications such as escort boats, pilot boats, fishing boats, passenger boats, ferries, cruising vessels, and seagoing patrol boats.

Quality and Compliance: MAN engines are noted for their compact design, low emissions, and compliance with IMO regulations. They are supported by a global service network and are ISO 9001 certified.

Technical Description: The engines are water-cooled, 4-stroke diesel engines with direct fuel injection, turbocharging, and intercooling. They feature high-strength casting engine blocks, closed lubrication systems, and electronic engine monitoring systems.

Contact Information: For further inquiries, contact the MAN Nutzfahrzeuge Group, Business Unit Engines, Department MVMV, in Nürnberg, Germany.
