Features

Fuel Efficiency

Fluid consumption optimized to match operating cycles of a wide range of equipment and applications while maintaining low operating costs.

Fluid consumption optimized to match operating cycles of a wide range of equipment and applications while maintaining low operating costs.

Installation

Exceptional power density enables you to use a smaller displacement engine than previously, and optimize the installation in your application. Fully configurable engine and compact aftertreatment minimize package size. Ideal for equipment with narrow engine compartments. Aftertreatment installation flexibility to meet all applications - including engine and remote mount options. Industrial Power Unit (IPU) available from factory to avoid significant design, validation and manufacturing costs.
