CAT ENGINES


At the heart of every great machine is a great engine — one that powers through day after day, month after month and year after year. The Caterpillar MINExpo 2021 display featured three of these reliable engines, all put to the test through a wide range of everyday and extreme conditions. 

 


 

of
C175

The C175 is one of our strongest and most reliable engines, with more than 22 million hours of operation in a wide variety of applications all over the world. From large mining trucks to generators to marine applications, the C175’s proven performance, optimized fuel usage and superior controllability have made it a powerful, cost-effective choice. 

BURNS LESS FUEL

Optimized for reduced fuel burn, lowering costs and limiting emissions for sustainable performance. 

Available in U.S. EPA Tier 4 Final and EU Stage V configurations for use in more strictly regulated areas.

The Cat Reman Advantage

The C175 displayed at MINExpo was remanufactured, returning it to like-new condition with significantly less environmental impact — and at a much lower cost — than manufacturing a new engine. Cat Reman is not reconditioning or rebuilding; rather, it is a unique, proprietary process that returns engines and other components to their original performance specifications and updates them with the most current design specifications. 

The result is an engine in like-new condition, tested to the same exhaustive standards and backed by the same Cat Parts Warranty as a new one.

3516 DGB

We've made a number of improvements to the 3516 over the years, and we continue to find new ways to extend life and reduce costs. Customers routinely report these engines outliving their projected service lives, often by thousands of hours.

  • E-series engine provides the same power with longer life
  • New skirt-guided pistons reduce wear, helping the engine last longer and reducing downtime
  • DGB conversion kit helps extend life even further, so you can get even more out of your investment
  • Available in a variety of configurations to meet application-specific need 


DYNAMIC GAS BLENDING

The C175 engine at MINExpo featured a Cat Dynamic Gas Blending™ (DGB) conversion kit, which replaces use of diesel fluid with liquefied natural gas (LNG) whenever possible. This technology has over 10 million operating hours in a wide variety of industries all over the world and is proven to dramatically reduce emissions and lower fuel costs — with zero impact on downtime or machine performance.

  • Up to 30% reduction in fuel costs
  • Reduced emissions
  • Same payload, performance and productivity as traditional engine
  • Can run solely on diesel when LNG is not available

C32B

The C32B is all new from the block up, with a number of design improvements focused on increasing durability. The new block is more robust, with a stronger crankshaft and larger main and rod journals. A new connecting rod features a larger big end and an optimized small end, as well as new pistons and cylinder heads.

  • Uses the proven U.S. EPA Tier 4 Final / EU Stage V emission control system pioneered on the C32 Cooled NOx Reduction System
  • Proven MEUI-C injectors
  • Fixed geometry turbocharger and a simple DOC aftertreatment system
  • Designed for direct replacement of current production core engine
  • You can pair a C32B long block with your existing iron, reducing rebuild costs 

Proven Technology

The C32B uses the proven U.S. EPA Tier 4 Final / EU Stage V emission control system pioneered on the C32. A cooled NOx Reduction System, proven MEUI-C injectors, a fixed geometry turbocharger and a simple DOC aftertreatment system offer excellent, reliable emission reductions. And with common parts and components to the C32, your Cat dealer and service technicians can leverage existing knowledge and experience.

Seamless Upgrade, Expert Support

The C32B is designed for direct replacement of current production core engines. That means you can pair a C32B long block with your existing iron, reducing rebuild costs. And as always, the C32B is backed by the the Cat dealer network — giving you boots-on-the-ground support connected to a worldwide network of expertise and knowledge.
