Product catalog summary

Engine Specifications
The document details the Caterpillar Marine Generator Set with an I-6, 4-Stroke-Cycle-Diesel engine. It is IMO compliant, with a displacement of 10.5 L, a bore of 120.7 mm, and a stroke of 152.4 mm. The engine is turbocharged and aftercooled, featuring a hydra-mechanical or PSG governor. The net dry weight is approximately 1905 kg.

Capacity for Liquids
The cooling system holds 25.0 L, and the lube oil system requires 38.8 L for refilling, with an oil change interval of 250 hours using Caterpillar DEO 10W30 or 15W40.

Standard Equipment
Includes a regular duty air cleaner, a 24V 35 Amp alternator, an engine-mounted radiator, a water-cooled manifold and turbocharger, and a brushless PM excited SR4 generator. It also features an RH instrument panel with gauges for oil pressure, water temperature, and fuel pressure.

Accessory Equipment
Optional accessories include an air starting motor, digital tachometer, electric shutoffs, and a spare parts kit. Additional features like a high capacity radiator and fan drive, and manual voltage control are available.

Performance Data
The generator set is rated at 155 ekW at 50 Hz and 170 ekW at 60 Hz. Performance data includes specific fuel consumption and fuel rates for different load percentages.

Rating Conditions
Engine performance parameters include a power increase of +3%, specific fuel consumption of +3%, and a fuel rate increase of +5%, based on standard conditions of 100 kPa, 25°C, and 30% relative humidity.

Generator Specifications
The Caterpillar SR4 generator is brushless, with a revolving field and permanent magnet excitation. It is a three-phase, 12-wire generator with Class F insulation. Voltage regulation is within +1/2%, and the generator weight is approximately 809 kg.

Dimensions
Overall dimensions include length, height, and width measurements, along with mounting hole specifications.

Overview
The document provides specifications and performance data for the Caterpillar 3306B Marine Generator Set, available in two power ratings: 170 ekW and 190 ekW at 60 Hz and 1800 rpm. It includes information on standard and accessory equipment, performance parameters, and dimensions.
