Caterpillar unveiled a new diesel engine platform at ConExpo 2023, designed to achieve increased power density, torque and fuel efficiency for a wide range of off-highway equipment.
The C13D engine will be available for early OEM pilots in 2025 and scheduled for production in 2026. It is designed for equipment such as rock crushers, screeners, and grinders; trenchers; agriculture tractors, harvesters and self-propelled sprayers; woodchippers; material-handling equipment; and large industrial pumps.
"It is not about bringing new technology to the forefront," said Dustin Childers, global marketing manager of Caterpillar Industrial Power Systems Division. "It's about applying that technology that Caterpillar has been investing in for decades to new applications."
By supplying comparable power and torque available from Caterpillar’s current 13-, 15- and single-turbo 18-liter engine platforms, the Cat C13D platform provides an opportunity for OEMs to downsize the engine and simplify design, assembly and supply chain requirements across multiple applications. This consolidation can also reduce maintenance, parts and technical training complexity for end users.
Childers said the 6-cylinder Cat C13D engine platform offers eight power ratings from 456 to 690 horsepower and delivers up to 3,200 Newton meters of peak torque.
"It's got a higher power-to-size ratio than really anything else in the market today," he said. "It's the same or better performance than the larger engine platforms that we have."
All eight power ratings will be available on a common core engine, enabling OEMs to reduce their inventory and integration costs, and the combination of the all-new rear gear train, stiffer core architecture and common rail fuel system reduces noise by up to 3 dB when compared with the C13D’s predecessors.
