New Cat C13B Engine
Published: 19/3, 2019
The new Cat C13B leverages a proven, reliable core engine 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 456 hp (340 kW) to 577 hp (430 kW) with peak torque reaching 1,943 lbft (2,634 Nm). The new engine offers peak power across a wide speed range enabling OEMs to optimize machine performance based on their application needs, with high torque rise for excellent load acceptance. 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% lighter and a 65% smaller than its current equivalent. Features such as integrated NO sensors offer a 50% 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 that allow 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. www.cat.com
