Yes, I would like to receive future marketing communications (such as email) from Caterpillar Inc., its affiliates and subsidiaries worldwide and the Caterpillar dealer network. Regardless of whether you decide to receive these marketing communications, Caterpillar will continue to send service/transactional messages, including those that have to do with any accounts that you may have with us.


The Cat® C13B engine supplies remarkable power and torque in a smaller, lighter engine package. With a aftertreatment that is 65% smaller and 54% lighter than its current equivalent and over 34 kW/L of power density, the C13B is designed to allow OEMs to downsize their engine platforms, lower installation costs and maximize uptime by providing long lift in the toughest applications.

High Power Density

High power density. With peak power increased up to 20%, you can look to downsize the displacement of the engine currently powering your application without impacting performance

Reliable, Quiet and Durable Power

World-class manufacturing capability and processes coupled with proven core engine designs, over 109 million off-highway field hours assure reliability, quiet operation, and many hours of productive life.

Fluid Efficiency

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


  • 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 remote mount and engine mounted from the factory
  • Industrial power unit (IPU) available from factory to avoid significant design, validation, and manufacturing costs
  • Low heat rejection levels allow for optimized cooling package at equivalent power
  • The C13B will be available in single label certification for EU Stage V, U.S. EPA Tier 4 Final, Japan 2014, and Korea Tier 4 Final providing global customers a single source solution that streamlines design, installation, and service processes

Low cost Maintenance

  • Worldwide service delivers ease of maintenance and simplifies the servicing routine
  • 5000-hour diesel particulate filter (DPF) ash service interval enables low-cost maintenance
  • Standard service intervals of 500 hours under normal operating conditions
  • The SOSSM program is available from your Cat dealer to optimize oil change intervals
  • Ideal for high-hour applications over 10,000 hours
  • Remote mount options for serviceable items such as oil and fuel filters


Every Cat engine is manufactured to stringent quality standards in order to assure customer satisfaction.

World-Class Dealer Support

  • Scheduled maintenance, including SOSSM sample
  • Customer Support Agreements (CSA)
  • Extended Service Coverage (ESC)
  • Superior dealer service network
  • Extended dealer service network through the Cat Industrial Service Distributor (ISD) program

Tier 4 Final, Stage V Aftertreatment Features

  • Clean emissions module (CEM) consisting of diesel oxidation catalyst (DOC) and combined diesel particulate filter (DPF) and high-efficiency selective catalytic reduction (SCR)
  • Maximum uptime with transparent aftertreatment regeneration, without operator distraction or impact to machine performance
  • PETU DEF capacity up to 93.7 liters (24.7 U.S. gallons)
  • Minimum 5000 hour service interval for DPF PETU filters
