C13D Diesel Engine

The Cat® C13D IPU configuration not only provides the flexibility and options found on a standard industrial engine, but also comes fitted with full aftertreatment and mounting, an integrated cooling system with air and coolant lines, and full wire harnessing with an engine-mounted ECM. Meeting U.S. EPA Tier 4 Final, EU Stage V and other equivalent emissions standards, the IPU allows for easier and faster installation, allowing the customer to spend less time worrying about integration and more time doing the work that matters.
