KTA38GC
Gas Compression Applications

Gathering and midstream compression requires
power that is reliable, durable and has world-class
support. It calls for the Cummins KTA38GC – an
emissions compliant, high-performance natural gas
engine that shares the proven heritage of the
Cummins K Series diesel engines and many of the
same heavy-duty components. It is no surprise that
the KTA38GC has low maintenance cost, stays
emissions compliant and keeps the gas flowing.
Every day.

Designed for the gas compression market, the
KTA38GC delivers exceptional reliability and low
cost of operation.
Base Engine – Most major components, including
block, crank, cam, gears and liners, are common
with the proven K38 diesel. Common gas unique
components on the KTA19GC and KTA38GC lower
your operating cost.
Emissions – Two configurations: Simple Lean-Burn
(SLB) or rich burn with catalyst. The SLB engine-out

COMPLIANT CAPABLE – The KTA38GC engine is capable
of meeting the SI NSPS regulations from the factory.
However, the owner/operator is required to conduct site
compliance testing and submit documentation per the EPA
SI NSPS requirements. Engines with the “E” designation
include a factory-supplied air/fuel ratio controller and a
Cummins Emission Solutions Three-Way Catalyst.
The KTA38GCSLB engine emits 2.0 gr/hp-hr NOx, 4.0 gr/hp-hr
CO, 1.0 gr/hp-hr VOC. This engine does not meet the revised
EPA SI NSPS requirements for non-emergency engines and is
offered only for use outside the U.S.

Air/Fuel Ratio Control – Oxygen sensor-based
air/fuel ratio control maintains emissions rate and
fuel consumption. Display shows O2, control valve
position and fault codes and provides for user input.
Air Handling – Twin turbocharger design delivers
maximum performance and life.
Fuel System – Impco® varifuel carburetors provide
stable operation and fuel tracking through all load
ranges.
Speed Control – Integral-throttle body electronic
governor provides precise and stable rpm control
under all load conditions.
Ignition System – Cummins Gas Compression
Ignition Module provides precision control and low
maintenance with sealed construction and highvoltage output.
Lubrication System – Deep, full-length, highcapacity oil pan. Combine full-flow and bypass oil
filters reduce maintenance costs while extending
service intervals.
Warranty – Cummins one year, unlimited hours.
