Cat® Dynamic Gas Blending™

Dynamic Gas Blending™ (DGB™) technology gives you a methane and diesel genset with the flexibility to handle variations in fuel quality and engine operating conditions – use gas when it’s available and diesel when it’s not. 

A dual-fuel solution

Your DGB generator set automatically adjusts to fuel quality changes, eliminating the need for field calibration. DGB ensures maximum substitution over the widest load range in the industry, so you enjoy the same service intervals and component longevity while maintaining diesel generator set power and transient response performance. Our Custom Power Solutions team will design a fuel-blending system to meet your specific needs.
