2025 Caterpillar Gas Compression Engines G3508J

The line of G3500 engines brings versatility, uptime, and low operating cost to your gas compression operation. They are equipped with ADEM A3 technology that enables highest performance and safety while maintaining low emissions. Ideal applications for G3500 engines include gas lift, gas gathering, and wellhead gas compression. The Cat G3508J gas engines are rated at 515 bkW (690 bhp) @ 1400 rpm and are NSPS site compliant capable with customer-provided air-fuel ratio control and aftertreatment.

Features may include:

Emissions

Meets U.S. EPA Spark Ignited Stationary NSPS Emissions for 2010

Lean Burn Engine Technology

Lean-burn engines operate with large amounts of excess air. The excess air absorbs heat during combustion reducing the combustion temperature and pressure, greatly reducing levels of NOx. Lean-burn design also provides longer component life and excellent fuel consumption.

Advanced Digital Engine Management

ADEM A3 control system providing integrated ignition, speed governing, protection, and controls, including detonation-sensitive variable ignition timing. ADEM A3 has improved: user interface, display system, shutdown controls, and system diagnostics.

Ease Of Operation

Side covers on block allow for inspection of internal components

Full Range Of Attachments

Large variety of factory-installed engine attachments reduces packaging time
