Cat® C13B Diesel Engine

C13B Tier 4 Diesel Engines - Highly Regulated


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 life in the toughest applications.


With a 65% reduction in size and 63% in weight from its previous engine equivalent, the Cat C13B is unparalled in supporting engine downsizing without an impact to overall performance. And with an absence of an EGR, the C13B provides a simplfied installation process, saving OEMs valauble time and costs.

Advanced Features

Offering peak performance across a wide range of speed, the Cat C13B is optimized to perform at its best no matter what surprises the job site brings. And with 20% more power and 19% more torque than its predecessor engine, the C13 has never been more ready to take on the tough challenges operators meet of every day.

Ideal Applications

Industrial, agricultural and construction applications such as: Compressors • Trenchers • Chippers • Grinders • Irrigation equipment • Bore rigs • Drill rigs • Pumps • Hydraulic power units

Total Cost of Ownership

The Cat C13B utilizes several technologies to deliver the lowest possible fluid consumption, including an overall fuel savings of 6% when compared to the C13 engine. And thanks to Caterpillar-patented technology the EGR has been eliminated, oil intervals are rated at 500 hours and 5,000 hours for ash services, helping OEMs and operators save on parts and service costs over the lifetime of the engine.
