C7.1
Cat® C7.1 ACERT™ Diesel Engine
The C7.1 Industrial Diesel Engine is offered in ratings from 129-225 bkW (172-302 bhp) @ 2200 rpm and meets U.S. EPA Tier 4 Final, EU Stage V emission standards. Industries and applications powered by C7.1 engines include: Agriculture, Aircraft Ground Support, Bore/Drill Rigs, Chippers/Grinders, Combines/Harvesters, Compactors/Rollers, Compressors, Construction, Cranes, Crushers, Feller Bunchers, Forestry, Forklifts, General Industrial, Hydraulic Power Units, Irrigation Equipment, Loaders/Forwarders, Material Handling, Mining, Mobile Earthmoving Equipment, Mobile Sweepers, Paving Equipment, Pumps, Skidders, Specialty Ag Equipment, Sprayers, Trenchers and Underground Mining Equipment.
Installation
Boasting one of Caterpillar's most modular engine designs to date, the Cat C7.1 also features an engine-mounted aftertreatment that saves OEMs valuable time and space when installing into a wide variety of machines—especially industrial and construction applications. OEMs also enjoy a 20% length, 5% height and 40% weight reduction when downsizing from 9-liter platforms.
Advanced Features
The Cat C7.1 uses passive regeneration technology, so operators can continue to perform their toughest tasks, in the most severe environments, without having to wait on the engine.
Ideal Applications
Industrial, agricultural and construction applications such as: Pumps • Compressors • Chippers • Grinders • Asphalt paving equipment • Hydraulic power units • Bore rigs • Drill rigs • Tractors
Total Cost of Ownership
The benefits to downsizing are many, including an 18% decrease in overall fuel consumption when downsizing from a 6-cylinder engine. With an added 3-4% decrease in overall DEF consumption and EGR integration, the cost savings don't take long to add up.
Cat Dealer Product Support
Scheduled maintenance, included warranty, reliable dealer service and a comprehensive global dealer support network—it’s all standard with the Cat C7.1. See your Cat dealer for details.
Safety
