Cat 3306B DITA Auxiliary
Cat 3306B DITA Auxiliary
The document outlines the specifications of the Marine Auxiliary Engine, specifically the I-6, 4-Stroke-Cycle-Diesel engine. It is compliant with IMO emissions standards and features a displacement of 10.5 L (641 cu. in.), a bore of 120.7 mm (4.75 in.), and a stroke of 152.4 mm (6.0 in.). The engine is turbocharged and aftercooled, with a hydra-mechanical or PSG governor. The net dry weight is 1027 kg (2265 lb) for heat exchanger cooled and 993 kg (2190 lb) for keel cooled configurations. The cooling system capacity is 15.9 L (4.2 U.S. gal), and the lube oil system capacity is 38.8 L (10.25 U.S. gal). The oil change interval is set at 250 hours, using Caterpillar DEO 10W30 or 15W40 oil. The engine rotates counterclockwise from the flywheel end.
The engine includes a regular duty air cleaner, a 24V 35 Amp alternator, a gear-driven cooling system, a water-cooled manifold and turbocharger, and an SAE No. 1 flywheel housing. The fuel system is equipped with a priming pump, transfer pump, and filters. Instrumentation includes gauges for oil pressure, water temperature, and fuel pressure. The lube system features a top-mounted crankcase breather and oil filter. The starting system is a 24V electric motor.
Optional accessories include an air starting motor, alarm contactors for oil pressure and water temperature, various alternators, a digital tachometer, electric gauges, and a range of shutoff and control devices. Additional equipment includes a hydraulic pump drive, magnetic pickup, and spare parts kit.
The engine's performance is detailed for different load percentages, with specific fuel consumption and power output data provided. The engine is rated at 161 bkW (216 bhp) at 1500 rpm, with performance parameters subject to a +3% variance in power and specific fuel consumption, and a +5% variance in fuel rate.
Dimensions are provided for both heat exchanger and keel cooled configurations, with detailed measurements for overall length, height, and width, as well as specific mounting dimensions.
Ratings are based on standard conditions of 100 kPa, 25°C, and 30% relative humidity, with additional ratings available for specific customer requirements.
