Product catalog summary

Specifications
The document outlines the specifications of the C280-8 In-Line 8, 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 148 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 925 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 cSt 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. The engine is painted in Caterpillar yellow and includes gear-driven pumps.

Performance Data
The engine is rated for marine auxiliary continuous use, with a power output of 2200 ekW and 2300 bkW at 900 rpm. It is certified under IMO/EPA Marine Tier II standards. The engine efficiency ranges from 38.5% to 43.5% depending on load, with fuel consumption varying accordingly. 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 and definitions are based on ISO 3046/1 and SAE J1995 standards, with specific reference conditions for temperature, pressure, and humidity.

Additional Information
The document includes altitude deration factors and aftercooler heat rejection factors 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 weights are also specified, with the engine length being 4511 mm and the dry weight approximately 19,000 kg.

Marine Certification
The engine ratings are approved by several marine classification societies such as ABS, BV, CCS, DnV, GL, LRS, and RINA. These approvals include factory line production, eliminating the need for society surveyor witness tests.

Rating Definitions and Conditions
The engine is identified as C280-8 Auxiliary & Diesel Electric Propulsion with a power output of 2600 ekW. Performance data is calculated under specified tolerances and conditions for comparison purposes. Actual performance may vary based on application and operating conditions. Power is rated according to NMMA procedures, with a 3% reduction for propeller shaft power.

Engine Dimensions
The engine dimensions are provided as follows: Length of Engine - 4511 mm (178.0 in), Length with Generator - 8040 mm (316.5 in), Width of Engine - 1961 mm (77.2 in), Height - 3937 mm (155.0 in). The dry weight of the engine is approximately 19,000 kg (41,800 lb), and the generator weight is approximately 11,340 kg (25,000 lb).
