Caterpillar introduced a record number of new models during a recent two-day press event at its Edwards Demonstration and Learning Center near Peoria, Ill. Among the 24 new models introduced were what it called its next-generation mini excavators, an all-new D6 dozer and articulated dump trucks. A new diesel engine was among the products, technology and solutions unveiled in early November.
The company said its new C13B diesel engine leverages a core engine with more than 109 million off-highway field hours and adds design improvements to permit manufacturers to downsize their engine platforms and lower installation costs.
The 12.5 L engine uses a non-EGR (exhaust gas recirculation) aftertreatment system to meet EU Stage 5 and U.S. EPA Tier 4 final emission standards and is available in multiple power ratings from 456 hp to 577 hp with peak torque reaching 1943 lb.-ft.
The company said the new engine offers a power density of up to 46 hp per liter, making engine downsizing possible without sacrificing performance or reliability. It delivers 15 L power at 32% less system weight.
“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,” said Jeff Moore, product director, research and development for 7.2 to 18 L engines.
The new aftertreatment system utilizes diesel oxidation catalyst
(DOC), diesel particulate filter (DPF) and selective catalytic reduction (SCR) technologies to eliminate the need for EGR. The Caterpillar patented design technology delivers a compact, lightweight system that is 63% lighter and a 65% smaller than its current equivalent, said the company.

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, said the company. The C13B will be available with engine-mounted aftertreatment and installed radiators from the factory. An established customization manufacturing system at the factory in Seguin, Texas, enables the production of these options, said the company.
The company said the new engine is idea for high-hour and long-life construction, agriculture and industrial applications over 10,000 hours.
