3512E DGB™ Well Service Engine

3512E DGB Well Service Engine

Introducing a game-changer for the well service industry. The Cat® 3512E Dynamic Gas Blending™ is the first U.S. EPA Tier 4 Final certified engine. Better yet, this innovative dual-fuel engine automatically maximizes the amount of gas used to displace diesel. That means you save big on fuel without giving up the power, performance, reliability or ease of maintenance and packaging of a Cat diesel engine. No other DGB engine on the market can match it.

  • Industry’s best diesel displacement rate of 85% — reducing your operating costs significantly
  • Industry’s widest fuel flexibility — operating on CNG, LNG, pipeline gas and field gas
  • Industry’s greatest GHG reduction — resulting in no net increase compared to the diesel model
  • Industry’s biggest technology advancements — keeping displacement high and emissions low

Lowest possible fuel costs. Smaller environmental footprint. Robust diesel performance. Discover how the 3512E Tier 4 Final DGB engine makes it all possible.
