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.
Features may include:
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.
- 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.
- Industrial, agricultural and construction applications such as: pumps • compressors • chippers • grinders • asphalt paving equipment • hydraulic power units • bore rigs • drill rigs • tractors
- 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.
- Scheduled maintenance, five-year warranty, superior dealer service and a comprehensive global dealer support network—it’s all standard with the cat c7.1.
- Validated with thousands of hours of field testing, the cat C7.1 is built to meet caterpillar's strict safety standards and customers' most demanding work sites throughout the world.
