Note
Net power ratings are tested at the reference conditions for the specified standard.
Note
Net power shown is the power available at the flywheel when the engine is equipped with alternator, air cleaner, diesel exhaust filter, and fan at minimum speed.
Note
No derating required up to 3000 m (10,000 ft) altitude. Auto derate protects hydraulic and transmission systems.
Note
Flywheel per the SAE reference conditions with the fan at maximum speed.
Note
The Cat C3.3B Tier 4 Final/Stage IIIB uses an active regeneration system which requires no operator interaction under normal conditions.
