Product catalog summary

Specifications
The document details the specifications of a V-12, 4-Stroke-Cycle-Diesel engine compliant with IMO/EPA Tier 2 standards. Key features include a bore of 280 mm, a stroke of 300 mm, and a displacement of 222 liters. The engine rotates counterclockwise from the flywheel end, with a compression ratio of 13:1. It is turbocharged and aftercooled, equipped with an electronic governor. The low idle speed is 350 rpm, and the rated speed is 900 rpm. The oil change interval is 750 hours, subject to S•O•SSM analysis.

Standard Equipment
The engine includes an air inlet system with a fresh water aftercooler, an electronic control system with a single ADEM™ A3 ECU, and a cooling system with engine coolant water drains. The exhaust system features a dry, gas-tight manifold. The fuel system uses distillate fuel with a viscosity range of 1.4 to 20 cSt at 38°C and includes a fuel transfer pump and duplex fuel filters. The lube oil system features centrifugal oil filters and crankcase explosion relief valves.

Performance Data
The engine is rated for marine auxiliary and diesel electric propulsion with a power output of 3300 ekW and 3460 bkW at 60 Hz and 900 rpm. Engine efficiency ranges from 39.0% to 42.7% depending on load, with corresponding variations in fuel consumption. Emissions data is provided for NOx, CO, and particulates, with nominal and "not to exceed" values.

Energy Balance and Conditions
The document provides detailed energy balance data, including fuel input energy and heat rejection to various components. Conditions for engine rating are based on ISO 3046/1 and SAE J1995 standards, with specific reference conditions outlined.

Additional Information
Altitude deration factors and aftercooler heat rejection factors are included to adjust performance based on environmental conditions. Sound data is provided for mechanical and exhaust noise at various distances from the engine. The engine dimensions and weight are specified, with the engine length being 4087 mm and the dry weight approximately 25,980 kg.

Rating Definitions and Conditions
The document outlines the performance specifications for the C280-12 Auxiliary & Diesel Electric Propulsion engine, rated at 3880 ekW. It emphasizes that performance data is calculated under specific tolerances and conditions for comparison purposes. Actual performance may vary based on application and operating conditions.

Engine Performance
The engine's power output at the flywheel is within standard tolerances up to a combustion air temperature of 49°C (120°F) and a fuel temperature of 52°C (125°F). Power is rated according to NMMA procedures as crankshaft power, with a 3% reduction for propeller shaft power.

Trademarks
The document notes that CAT, CATERPILLAR, and related logos and trade dress are trademarks of Caterpillar and require permission for use.

Engine Dimensions
The engine dimensions are specified as follows: Length of Engine - 4087 mm (161.0 in), Length with Generator - 8040 mm (316.5 in), Width of Engine - 2000 mm (78.7 in), Height - 4085 mm (160.8 in). The dry weight of the engine is approximately 25,980 kg (57,276 lb), and the generator weight is approximately 14,970 kg (33,000 lb).
