Gathering compression applications require power that is reliable, durable and has world class support. It calls for the Cummins KTA19GCE – an emissions compliant capable, 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 KTA19GCE has low maintenance cost, stays emissions compliant and keeps the gas flowing. Every day.

Disclaimers
(1) All data is based on the engine operating with fuel system, water pump, and 6 in H2O (1.49 kPa) inlet air restriction with 3 in (76 mm) inner diameter, and with 1 in Hg (3 kPa) exhaust restriction with 3 in (76 mm) inner diameter; not included are alternator, fan, optional equipment and driven components. Coolant flows and heat rejection data based on coolants as 50% ethylene glycol/50% water. All data is subject to change without notice.
Designed for the gas compression market, the KTA19GCE 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 K19 diesel. Common gas unique components on the KTA19GCE and GTA38GCE lower your operating cost.
Emissions – 2011 NSPS Compliant Capable (1/2/.7 NOx/CO/VOC), Factory Supplied AFR, FW Murphy Supplied RB Emissions Kit, 0.5g NOx Capable (Consult Factory).
Air/Fuel Ratio Control – Direct-acting Electronic Pressure Regulator Assembly controlled by engine specific calibration provides reliable emissions control.
Air Handling – Turbocharger design delivers maximum performance and life. It includes factory-installed heavy-duty air cleaner.
Speed Control – Integrated electronic governor provides stable rpm control with optional input to monitor and control suction or discharge pressure.
Ignition System – EICS™ capacitive discharge ignition with smart-coil technology provides reliable spark and individual cylinder diagnostics and knock sensing capabilities.
Lubrication System – Deep, full-length, high-capacity oil pan. Combination full-flow and bypass oil filters reduce maintenance costs while extending service intervals.
Flywheel and flywheel housing – SAE 0, cast iron, including provisions for one 5/8-18 and two 3/4-16 magnetic pickups, machined to accommodate starter mounting.
Power Take-Off (PTO) – Front stub shaft options are offered for driving the compressor cooler fan.
Starting system – The standard system features a robust Delco Remy® 39MT 24-volt starters with SAE #3 mounting flanges. An air/gas starter is optional.
Electrical system – Includes a 24-volt alternator.
Cooling system – A two-pump/two-loop cooling system effectively separates the aftercooler and jacket water coolant circuits to maintain lower intake manifold temperatures and providing capability for higher power ratings. Integrated coolant filters add corrosion protection for the jacket water circuit.
Exhaust system – The water-cooled manifolds reduce surface and exhaust gas temperatures.
Warranty – Cummins one year, unlimited hours. Backed by a worldwide distributor network.
