Cummins upgrades KTA19 gas compression engine with adaptive FW Murphy fuel system
Cummins is offering an optional FW Murphy fuel system for its KTA19 gas compression engine that automatically adjusts to variable field gas, cutting manual calibration and unscheduled downtime.
- 19 liters
- June 2026
What Happened
Cummins Inc. has introduced an upgrade to its KTA19 Gas Compression Electronic (GCE) engine, integrating the FW Murphy Mass Flow Air/Mass Flow Gas (MFA/MFG) fuel system to improve performance, uptime, and reliability in field gas applications. The KTA19GCE is a 19-liter natural gas engine widely used in gas compression operations. The new configuration is offered alongside the existing factory fuel system and is designed to better manage variability and impurities commonly found in field gas.
Field gas composition often fluctuates, requiring manual calibration and ongoing adjustment to maintain engine performance. The FW Murphy MFA/MFG fuel system automatically adapts to these changes, helping maintain consistent operation with minimal intervention. This reduces the risk of unscheduled shutdowns, increases uptime, and extends component life.
“This upgrade improves how the KTA19GCE performs in real-world field gas conditions, where fuel quality can vary significantly. By reducing the need for manual adjustments, it helps our customers maintain stable operation and meet uptime targets.”
Cummins collaborated with FW Murphy, a recognized leader in gas compression technology, to integrate the new system. The MFA/MFG system enhances fuel control and responsiveness, supporting consistent performance across varying operating conditions. The upgrade will be offered alongside current offerings, giving customers flexibility to select the configuration that best meets their application requirements while Cummins gathers customer feedback. Available beginning June 2026, it expands the KTA19GCE's capability in field gas applications, supporting more stable operation and reducing maintenance demands in challenging environments.

Why this matters
Field gas composition varies, so operators must manually calibrate engines to maintain performance. The new fuel system automatically adapts, reducing unscheduled shutdowns and extending component life. This helps gas compression customers achieve steadier operation and meet uptime targets.
