Houston, Texas – Caterpillar Oil and Gas is pleased to announce the development of the new land well service 3512E Dynamic Gas Blending™ dual fuel engine. The 3512E DGB™ engine will be certified to U.S. EPA Tier 4 Final emissions standard while offering the highest natural gas substitution in its class.

Unlike previous versions offering dual fuel operation, the 3512E DGB will include factory solutions that emit approximately the same or less greenhouse gas (GHG) emissions as a comparable 3512E Tier 4 Final diesel engine. Additionally, the dual fuel performance of the new 3512E DGB has significantly increased compared to similar engines in its class with the ability to achieve 85% diesel displacement, further allowing for lower operating costs.

With identical configurations as the 3512E diesel engine, the new 3512E DGB engine was designed for 2250 and 2500 bhp ratings.  Separate circuit and air to air after cooling options are identical to the core diesel, including mounting dimensions for like trailer design.  On engine gas filtration is standard as well as the same options available for the core diesel including the Engine Idle Reduction System (EIRS). The engine’s robust diesel design will allow for extended life and lower owning and operating costs.   

 “Caterpillar’s 3512 platform has decades of experience operating in the oilfield. And the addition of the 3512E DGB will continue that legacy while helping customers burn natural gas,” said Derek Kamp, Well Service Industry Manager.
