Product catalog summary

Engine Specifications
The document details the specifications for Caterpillar® I-4, 4-Stroke-Cycle-Diesel engines, highlighting a displacement of 4.4 L, bore of 105 mm, and stroke of 127 mm. These engines feature direct injection, are either naturally aspirated or turbocharged, and utilize an electronic governor. The dry weight of the generator set package ranges from 776 kg to 1021 kg, depending on the model.

System Capacities
The cooling system has a capacity of 17.5 L, while the lube oil system holds 8.5 L, with an oil change interval of 500 hours.

Air Inlet and Cooling Systems
The air inlet system includes an air cleaner with a service indicator and a glowplug cold start system. The cooling system is radiator-cooled, suitable for up to 50°C ambient air, and features a deaeration expansion tank and a gear-driven centrifugal jacket water pump.

Exhaust and Fuel Systems
The exhaust system includes an insulated exhaust elbow and a water-cooled exhaust manifold. The fuel system comprises a primary fuel filter/water separator, a secondary fuel filter, and an electric fuel priming pump.

Generator and Governing System
The generator is 12 lead reconnectable, 3 phase, brushless, and can provide 300% short circuit current for up to 10 seconds. It includes a solid-state voltage regulator and Class H insulation, with an electronic governing system.

Mounting and Starting Systems
The mounting system features a steel base frame with anti-vibration mounts, and the starting/charging system is a negative isolated ground electric system.

Standard and Optional Equipment
Standard equipment includes a governor droop kit, space heater kit, and double wall fuel lines. Optional attachments offer marine classification society approval and additional starter options.

Performance and Rating Conditions
Performance data is based on SAE J1228/ISO8665 standards, with ratings for different ambient temperatures and specific power outputs at 50 Hz and 1500 rpm.

Dimensions
Package dimensions vary slightly between models, with lengths from 1658 mm to 1764 mm, a consistent height of 1187 mm, and a width of 700 mm.

Overview
The document provides comprehensive specifications and performance data for Caterpillar's C4.4 Marine Generator Sets, available in various configurations for different power outputs and frequencies.

Specifications
The generator sets are powered by a 4.4 L, I-4, 4-stroke-cycle diesel engine with direct injection and an electronic governor, available in different power ratings, including 65 ekW at 50 Hz and 82 ekW at 50 Hz. The engines are turbocharged and aftercooled, with a dry weight ranging from 776 kg to 1076 kg.

Performance Data
The generator sets operate at 1500 rpm for 50 Hz models and 1800 rpm for 60 Hz models, with fuel consumption ranging from 13 L/hour to 24.6 L/hour. The total harmonic content is kept below 4% for efficient performance.

Dimensions
Package dimensions vary slightly between models, with lengths from 1658 mm to 1861 mm, heights around 1174 mm, and widths approximately 821 mm.

Standard Equipment
Each generator set includes a control system with an electronic governor, a cooling system with a radiator, a fuel system with primary and secondary filters, and a lube system with a 500-hour oil change interval. The mounting system includes a steel base frame with anti-vibration mounts.

Optional Attachments
Optional features include a governor droop kit for paralleling, space heater kits, double wall fuel lines, and jacket water heater options. Marine Classification Society (MCS) approved packages are available for specific requirements.

Rating Conditions
Ratings are based on standard conditions of 100 kPa, 25°C, and 30% relative humidity, with adjustments available for specific customer needs. Actual performance may vary based on application and operating conditions.
