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
- 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.
