Engine Model

Cat® C7.1 ACERT™

Emissions

Engine meets U.S. EPA Tier 4 Final/EU Stage IV emission standards.

Note (1)

* Range 4 power and torque is equal to Performance Mode with Caterpillar Power by Range technology.

Note (2)

Net power ratings are tested at the reference conditions for the specified standard and denote power available at the flywheel when the engine is equipped with alternator, air cleaner, emission components and fan at specified speed.

Note (3)

No derating required up to 3000 m (10,000 ft) altitude. Auto derate protects hydraulic and transmission systems.

Note (4)

Spark arrester performance as standard – Meets the performance requirements of EN 1834-1.2000 (section 6.4.2 Visual Test).
