Cat says new 12.5L C13B engine delivers 15L powerhouse

 Caterpillar introduced a new engine it says delivers is 15-litre power at a system weight that is 32 percent lighter.

Designed for high-hour and long-life construction, agriculture and industrial applications of more than 10,000 hours, the new C13B is a 12.5-litre engine with a power density reaching 46 horsepower per liter.

It’s available in multiple power ratings from 456 hp to 577 hp. Peak torque is 1,943 lb.-ft., and Cat says the engine boasts excellent load acceptance thanks to high torque rise.

Cat says the engine delivers peak power across a wide speed range, “enabling OEMs to optimize machine performance based on their application needs.”

The C13B features a new aftertreatment system that utilizes a diesel oxidation catalyst (DOC), diesel particulate filter and high-efficiency selective catalytic reduction (SCR) to eliminate the need for exhaust gas recirculation. As a result, Cat says fuel consumption has been reduced by up to 6 percent and the system is 63 percent lighter and 65 percent smaller than its current equivalent.

The engine is configurable with a wide range of factory installed options, Cat says, giving OEMs a choice of transmission interfaces, rotating electrics and other machine interfaces. It will be available with engine-mounted aftertreatment and installed radiators from the factory.

“We understand that not all customers have the resources to design, manufacture and validate on the same scale,”  says Jeff Moore, product director of research and development for Cat’s 7.2 to 18L engines. “For that reason, Caterpillar designs its products with the flexibility to accommodate various OEM requirements, resulting in lower installation costs.”

The C13B will enter full production in 2019.
