Cat® Dynamic Gas Blending™ (DGB) Technology

Get The Full Cat® Dynamic Gas Blending™ Experience

Cat® Dynamic Gas Blending is a dual-fuel technology that allows existing Cat diesel engines to burn natural gas, diesel fuel or a combination of the two. DGB technology is specifically designed for well services and drilling applications and helps operators lower greenhouse gas (GHG) emissions, reduce fuel use and expand fuel options.

Dynamic Gas Blending Leading The Way Since 2012

How Does Dynamic Gas Blending Technology Work?

 

Each iteration of DGB brings more capabilities to more equipment across industries.

DGB technology uses gas when available and seamlessly reverts to diesel-only when unavailable. Automatic fuel blending has grown to include a wide range of natural gas fuel qualities to help offset fuel costs without sacrificing performance.

Built To Be The Best

DGB continues to evolve to optimize gas substitution across all applications. Starting in 2012, we launched our initial DGB solution to help give customers relief from rising diesel fuel costs. Cat DGB continues to deliver intelligent, on-the-fly adjustments that had never been seen before.

DGB capabilities and benefits:

  • Seamlessly adjusts from gas to diesel-only when gas becomes unavailable
  • Continuously optimizes gas substitution while maintaining diesel power and transient performance
  • Designed to handle a wide range of fuel quality
  • Automatically adjusts to changing gas quality
  • All engines are factory or dealer tested prior to going to the field
  • Closed-loop feedback continuously monitors output and combustion characteristics to maintain U.S. EPA emission standards
