Combining the proven, heavy-duty design of the legendary Cummins K Series platform with advanced natural gas technology, this engine delivers exceptional reliability, emissions compliance, and low operating cost to keep critical gas flows uninterrupted every day.


Target Equipment & Core Applications

The KTA38-GC is purpose-built for one primary sector, excelling in applications where durability and dependable operation are paramount:

  • Oil & Gas Industry: The prime mover for gas compression equipment in gathering lines and midstream applications.


Core Technologies & Competitive Advantages

1. Proven Heavy-Duty K Series Platform
This natural gas engine shares its core architecture—including the block, crankshaft, camshaft, and cylinder liners—with the proven and rugged Cummins K38 diesel engines. This commonality ensures legendary durability in harsh environments and simplifies maintenance.

2. Advanced Natural Gas Fuel & Combustion System
Engineered for stable performance on natural gas, it features Impco carburetors for precise air/fuel mixing and stable operation across all load ranges. Its twin-turbocharger design maximizes performance and component life. The engine offers configurations for both lean-burn and rich-burn operation with a 3-way catalyst, allowing for flexible emissions compliance.

3. Precision Control for Optimal Performance
An oxygen sensor-based air/fuel ratio control system actively maintains optimal combustion for consistent emissions and fuel efficiency. Engine speed is managed by a precise integral-throttle body electronic governor, ensuring stable RPM control under varying load conditions.

4. Global Support & Warranty
Backed by Cummins' comprehensive one-year, unlimited-hour warranty and a worldwide distributor network, operators gain access to unparalleled service and support.
