Cat® G3508 Industrial Gas Engine

Overview

Cat® G3508 Industrial Gas Engine. Ratings: 391 bkW (524 bhp) @ 1200 rpm and 500-514 bkW (670-690 bhp) @ 1400 rpm are NSPS site compliant capable with customer-supplied aftertreatment. For specific emission information, please consult your local Cat Dealer.

Emissions
Ratings are NSPS site compliant capable with customer-supplied aftertreatment. For specific emission information, please consult your local Cat Dealer.
Engine Design
  • Proven reliability and durability
  • Ability to burn a wide spectrum of gaseous fuels
  • Robust diesel strength design prolongs life and lowers owning and operating costs
  • Broad operating speed range
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.
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.
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
Quality
Every Cat engine is manufactured to stringent quality standards in order to assure customer satisfaction.
World-class Product Support Offered Through Global Cat Dealer Network
  • Scheduled maintenance, including S•O•SSM sample
  • Customer Support Agreements (CSA)
  • Caterpillar Extended Service Coverage (ESC)
  • Superior dealer service network
  • Extended dealer service network through the CatIndustrial Service Distributor (ISD) program
