Cat® C15 Diesel Engine
THE RUNDOWN
Installation
The Cat C15 offers a fully-configurable engine across a wide range of power nodes, flexible aftertreatment mounting options and the ability to install the engine's IPU straight from the factory, so OEMs can keep installation time and costs to a minimum.
Advanced Features
With transparent regeneration technology built into every Cat C15, operators can continue to be productive without ever having to wait. The C15 also features a 5,000-hour DPF service interval and DEF capacity of 93.7 liters, giving machine operators the opportunity to spend more time on the job site and less time in the shop.
Ideal Applications
Industrial, agricultural and construction applications such as: Compressors • Trenchers • Chippers • Grinders • Irrigation equipment • Bore rigs • Drill rigs • Pumps • Hydraulic power units
Total Cost of Ownership
Operators know the true costs of owning an engine goes beyond the rough and reliable exterior. That's why the Cat C15 was developed to optimize fluid consumption based on a wide range of operating cycles and applications. And with 500-hour maintenance intervals, owners can keep parts and service costs low.
Cat Dealer Product Support
Say goodbye to complicated service routines and start enjoying scheduled maintenance and worldwide dealer support with the Cat C15. Not only does the engine come with a warranty, it’s also backed by the Cat dealer support network across 192 countries. See your Cat dealer for details.
Safety
Each Cat C15 features a clean emissions module that uses DOC, DPF and SCR technologies to keep the engine running cleaner, longer. Besides, cleaner air isn't just good for the engine, it's also a win for the environment and makes for safer working conditions.
