3512E DGB Tier 4 Final

Land Well Service 3512E Dynamic Gas Blending dual fuel Engine

3512E Dynamic Gas Blending SCAC Petroleum Engine Well Servicing Engines

DESCRIPTION

The new land well service 3512E Dynamic Gas Blending™ dual fuel engine will be certified to U.S. EPA Tier 4 Final emissions standard while offering the highest natural gas substitution in its class. 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.

Engine Design

  • Proven reliability and durability
  • Robust diesel strength design prolongs life and lowers owning and operating costs
  • Broad operating speed range
  • Air shutoff – integrated with engine controls
  • EGR/Diesel Oxidation Catalyst (DOC)/common rail fuel system to meet Tier 4 Final/Stage IV emission standards
  • DEF free solution – eliminates the storage, logistics, and issues involved with SCR/DEF design engines
  • Individual cylinder based gas injection system.
  • Engine mounted DGB controls.
  • Engine mounted Gas filter, water coalescing type

Cooling System

Separate Circuit Aftercooler (SCAC) and Air-to-Air-Aftercooler (ATAAC)

Engine-Mounted Package

Integrates with engine, aftertreatment, heavy-duty air cleaners, residential grade mufflers available in stainless or carbon steel

Engine-Mounted Transmission Oil Cooler

Integration with engine cooling system allows ease of installation and a tighter overall engine package
