Cat® C27 Diesel Engine

It may be big, but the power-dense Cat C27 is a fully-configurable common core engine that makes installation across a wide variety of applications simple. With options like rear-mounted turbos and engine-mounted aftertreatment, it's now easier than ever to install. And becuase the C27 is DEF-free, there's even more room to maneuver under the hood.

Say goodbye to DEF, thermal management and engine regeneration with the Cat C27. Thanks to advances in Caterpillar's technology, the larger-than-life engine is practically maintenance free.

Industrial and construction applications such as: Dredges • Chippers • Grinders • Emergency water pumps • Rock drills

Carefully crafted for efficiency, the Cat C27 fuel consumption is optimized to meet the demanding operating cycles of just about any machine. And with no DEF to worry about, owners can save on parts and maintence costs while also remaining maintenance-free for the life of the engine.

Reliable dealer service and support, scheduled maintenance and an included warranty: it’s what Cat C27 owners can expect with their new engine. See your Cat dealer for details.

Featuring a clean emissions module, the Cat C27 uses DOC, DPF and SCR technologies to keep the engine—and the air around it—cleaner, not only making for a more efficient machine, but also a safer job site.
