2022 Caterpillar Marine Generators C4.4 Acert

The C4.4 ACERT marine genset packages with heat exchanger or keel cooling are available with 60 Hz ratings of 60, 75, 99, 118 ekW and 50 Hz ratings of 65, 80, 99 ekW. Radiator cooled gen sets are with 60 Hz ratings of 51, 66, 90, and 105 ekW and 50 Hz ratings of 58, 73, and 88 ekW. The C4.4 ACERT meets U.S. EPA Tier 3 and EU CCNR Stage II emissions regulations. The C4.4 ACERT is electronically controlled with a Common Rail fuel system.

Features may include:

Noise Reduction
  • New block for low noise and vibrations, insulated timing case cover, isolated oil pan (also provides ease of maintenance), improved pump and gear train system, stiffer crankshaft, multiple fuel injection strategy, 4 valve cross flow head, double curvature on thick walled crankcase, piston optimized for high speed operation
Hydraulic Tappets
  • Hydraulic tappet adjustment removes the need for manual tappet adjustment, that on the 1006 (C6.6) needed to happen every 500 hours. This system is operated by oil pressure, and this saves the customers a considerable amount of cost from an operating perspective.
Improved Smoke Levels
  • Improved smoke levels from C4.4 mechanical engine
Serpentine belts to achieve longer service intervals
  • These belts are more efficient, as they provide more drive surface. Less heating is created during running, and the belt will also last longer. The poly v belt cannot twist over like a single v belt, and any wear of the poly v belt becomes apparent a long time before failure.
Integrated Base Frame
  • Suitable for wide range of auxiliary accessories
Gear Driven water pumps
  • Lower servicing costs, reduced down time
Water-cooled turbo
  • Suitable for “gas tight” applications
Tailored Technology
  • Meets customer requirements in: voltage, cooling, twin pocket fly wheel housing, and factory options for starting
Caterpillar package
  • Fully packaged generator set
Lube System
  • Oil system holds 11l (2.8 gal), 500-hour oil change interval, max continuous operation angle is 25° (any direction), max intermittent operation angle 30° (any direction)
Design Features
  • Control panel standard on lhs with single leg box, control panel location interchangeable between 3 positions available as option
