Caterpillar Expands EU Stage V, U.S. EPA Tier 4 Final Industrial Engine Range with New 12.5 Liter Offering

For Worldwide Release: November 2017 
Release Number: 659PR17

Caterpillar will expand on what is already the industry’s broadest industrial engine range with the addition of the new Cat® C13B. The 12.5 liter engine will leverage a proven, reliable core of components with over 68 million hours of real world experience and complementary technology to the C9.3B platform that was launched in 2016 and is nearing production.

“Our customers expect reliability and durability, but they need it from a simpler, lighter package with more power and that’s what we’re giving them with our new engines,” explains Jeff Moore, Product Manager for 7.2-18 liter engines.

Designed to meet Stage V and Tier 4 Final emission standards, the 6 cylinder, 12.5 liter engine combines upgraded air, electrical and aftertreatment systems to produce a range of powers from 340-430 kW and up to 2640 Nm of torque out of a package that is 30 percent lighter at these performance levels, when compared to previous models.

Increased performance is accentuated with transparent aftertreatment regeneration to maximize uptime and improvements in fuel consumption minimize cost of ownership. The C13B provides for all of the critical success factors required by off-highway original equipment manufacturers (OEMs) in all industrial sectors.

As with all Caterpillar 9-18 liter engines, the C13B will be offered in a number of configurations to provide OEM customers the flexibility to reduce the cost of installation.

Engine mounted afterteatment (EMAT) and full Industrial Power Unit (IPU) configurations are offered out of the factory in Seguin, Texas, USA. Remote mounted aftertreatment is also possible, with minimal installation requirements between the engine and aftertreatment.

Caterpillar will also certify its existing Stage IV, Tier 4 Final engines in its C13, C15 and C18 product range to meet Stage V emission standards, needing only minimal changes to the Diesel Particulate Filter (DPF) internals to meet the standards. Dual label certification – Stage V and Tier 4 Final - will be offered for its range of 9-18 liter products from 250-597 kW giving customers the opportunity to commonize their products across regions.

Caterpillar’s DPF solutions in this range have over 282 million hours of proven performance in the field. There are no changes to customer interface points for existing products, allowing for a seamless changeover and enabling customers to focus on their own product improvements.

“The C13B and all Cat industrial engines are designed with the customer in mind. We meet emission standards while delivering increased power density, fuel efficiency, and reduced complexity to add real value for our customers,” stated Moore.
