Power

The electronic control of the 6.6 liter engine with ACERT Technology simultaneously optimizes fuel economy and performance while meeting the most stringent emissions standards. The electronic governor ensures power quality that’s suitable for sophisticated equipment, such as computers and other electronics.

Economy

Competitive pricing, outstanding fuel efficiency, extended service intervals, and ultra long life, all contribute to the overall low owning and operating costs of the C6.6 ACERT

Environmental responsibility

The C6.6 ACERT is IMO emission-compliant; both 60 Hz and 50 Hz meet EPA Tier II regulations.

Peace of mind

The Caterpillar 12-month warranty and available Extended Service Coverage keep the C6.6 ACERT — and your operation — on a smooth course.

Flexibility

C6.6 ACERT packages offer six ratings. Three standard cooling options are also available: Sea water after cooling, keel cooling, and radiator cooling. In addition, the C6.6 ACERT is compatible with a variety of fuels, including kerosene, jet aviation fuel, and 20 percent bio-fuel.

Safety

Automatic safety shutdowns include low oil pressure, high water temperature, and overspeed.
