New Cat® C13B engine delivers more power in a compact, lightweight design that allows OEMs to downsize engine platforms

For Release in North America, Europe, Eurasia, Asia: December 2018 
Release Number: 581PR18

The new Cat® C13B leverages a proven, reliable core engine with over 109 million off-highway field hours combined with design improvements to create customer value, allowing OEMs to downsize their engine platforms, lower installation costs and maximize uptime. The 12.5-liter engine features a patented non-EGR aftertreatment system to meet EU Stage V and U.S. EPA Tier 4 Final emission standards and is available in multiple power ratings from 340 kW (456 hp) to 430 kW (577 hp) with peak torque reaching 2634 Nm (1943 lb.-ft.).

Expanding what is already the industry’s broadest industrial engine offering, the new C13B engine offers high power density, reaching 34-kW/L (46-hp/L), that allows engine downsizing without sacrificing performance or reliability. It delivers 15-liter power at 32 percent less system weight.

The new engine offers peak power across a wide speed range enabling OEMs to optimize machine performance based on their application needs, plus it features high torque rise for excellent load acceptance.

“With a proven, reliable core engine and our extensive experience across all industrial sectors, the C13B represents a continuation of our commitment to develop engines that deliver improved performance, simplify installation and reduce operating costs,” says Jeff Moore, product director, research and development for 7.2- to 18-liter engines. 

The new aftertreatment system utilizes diesel oxidation catalyst (DOC), diesel particulate filter and high-efficiency selective catalytic reduction (SCR) technologies, eliminating the need for exhaust gas recirculation. The Caterpillar patented design technology delivers a compact, lightweight system that is 63 percent lighter and a 65 percent smaller than its current equivalent. Features such as integrated NOx sensors offer a 50 percent reduction in customer interface connections, optimizing component packaging and integration requirements.  Aftertreatment regeneration is transparent to the operator without impacting machine performance, offering maximum uptime.

The C13B is fully configurable with a wide variety of factory installed options offered that allow OEMs a choice of transmission interfaces, rotating electrics and many other machine interfaces. The C13B will be available with engine-mounted aftertreatment and installed radiators from the factory, offering plug and play solutions that minimize machine design, validation and installation costs. An established customization manufacturing system at the factory in Seguin, TX enables production of these options while maintaining high build quality.

"We understand that not all customers have the resources to design, manufacture and validate on the same scale," says Moore. "For that reason, Caterpillar designs its products with the flexibility to accommodate various OEM requirements, resulting in lower installation costs."

Ideal for high-hour and long-life construction, agriculture and industrial applications over 10,000 hours, the Cat C13B engine offers increased performance while lowering operating and maintenance costs. High efficiency SCR and the elimination of EGR are the key enablers to improving fuel consumption by up to 6 percent while maintaining neutrality of total fluid consumption. Factory options such as remote mounted fuel/oil filters and right- or left-side fluid gauges improve serviceability. Standard service intervals of 500 hours, under normal operating conditions, and up to 5,000-hour DPF ash service intervals deliver low-cost maintenance.

Product support to keep the C13B engine operating at maximum efficiency is provided by the world-class global Cat dealer network. Cat dealers offer genuine Cat parts and a variety of services including scheduled maintenance with S∙O∙SSM sampling, customer support agreements (CSAs) and extended service coverage (ESC) to optimize engine life and lower operating costs. In addition, dealer service technicians are trained to service the entire Cat industrial engine line.

The new C13B engine has undergone extensive lab and field-testing to ensure durability and reliability. With a successful pilot program underway, the C13B will enter full production in 2019.
