Installation
Thanks to the modular and compact structure of the Cat C4.4, engine installation on any type of machine becomes effortless. Additionally, when downsizing from five-liter platforms, original equipment manufacturers can observe a 20% reduction in length, a 5% reduction in height, and a 40% reduction in engine weight, resulting in optimal installation costs.
Advanced Features
With a 15% increase in power density and a 10% increase in torque compared to its predecessor, the compact design of the Cat C4.4 reduces heat losses for more efficient engine performance, enabling operators to tackle the most demanding tasks with ease.
Ideal Applications
Applications in the industrial, agricultural, and construction sectors, such as: Pumps • Compressors • Chippers • Grinders • Asphalt paving equipment • Hydraulic power units • Drilling rigs • Trenchers • Tractors.
Reduce Total Cost of Ownership
Many factors can influence the cost of ownership of your engine throughout its lifespan. These can range from simple fluid requirements to highly complex weight distribution challenges. In either case, the Cat C4.4 is covered by warranty. Compared to equivalent 6-cylinder platforms, the C4.4 offers over 18% fluid consumption savings and is specifically balanced to ensure optimal daily operation.
After-Sales Service
The Cat C4.4 simplifies maintenance and service operations with the support of the global Cat dealer network. For added peace of mind, your Cat engine comes with a warranty. For more information, please contact your Cat dealer.
