Product catalog summary

Specifications
The C280-6 In-Line 6, 4-Stroke-Cycle-Diesel engine is compliant with IMO/EPA Tier 2 standards. It features a bore of 280 mm, a stroke of 300 mm, and a displacement of 111 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 1025 hours, and the cooling system options include keel or heat exchanger types.

Standard Equipment
The engine includes an air inlet system with a fresh water aftercooler, a turbocharger lubricated by engine oil, and an electronic control system with a single ADEM™ A3 ECU. The cooling system features engine coolant water drains, and the exhaust system has a dry, gas-tight manifold. The fuel system requires distillate fuel with specific viscosity and includes a fuel transfer pump and duplex fuel filters. The lube oil system has centrifugal oil filters and various valves for pressure regulation and explosion relief.

Performance Data
The engine is rated for marine auxiliary and diesel electric propulsion with a power output of 1650 ekW and 1730 bkW at 900 rpm, certified under IMO/EPA Marine Tier II standards. Engine efficiency can reach up to 42.6% at full load. Fuel consumption is detailed for different loads, with specific values for ISO 3046/1 and nominal conditions. Emissions data for NOx, CO, and particulates are provided with 'not to exceed' and 'nominal' values.

Energy Balance and Conditions
Detailed energy balance data includes fuel input energy and heat rejection to components like the jacket water, atmosphere, oil cooler, and exhaust. Engine rating conditions are based on ISO 3046/1 and SAE J1995 standards, with specific reference conditions for temperature, pressure, and humidity.

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. Guidelines for generator efficiency and continuous power applications are also outlined.

Rating Definitions and Conditions
The engine's performance specifications are calculated under specific tolerances and conditions for comparison purposes, with actual performance varying based on application and operating conditions. The engine is rated at 1949 ekW for auxiliary and diesel electric propulsion.

Performance Specifications
The engine's power output is measured at the flywheel, with 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.

Engine Dimensions
The engine length is 3691 mm (145.0 in), extending to 7120 mm (280.3 in) with the generator. The width is 1961 mm (70.7 in), and the height is 3934 mm (154.9 in). The dry weight of the engine is approximately 15,680 kg (34,496 lb), and the generator weight is approximately 8165 kg (18,000 lb).
