Advantages and Features
Engine Design
- Proven reliability and durability- Ability to burn a wide spectrum of gaseous fuels- Robust diesel strength design prolongs life and lowersowning and operating costs- Broad operating speed rangeEmissions
- Meets U.S. EPA Spark Ignited Stationary NSPSEmissions for 2007/8- 2.0 g/bhp-hr NOx emission versions available- Larger turbocharger and aftercooler provide leanair/fuel mixture, low emissions, and excellent fuelconsumptionLean Burn Engine Technology
Lean-burn engines operate with large amounts of excessair. The excess air absorbs heat during combustionreducing the combustion temperature and pressure,greatly reducing levels of NOx. Lean-burn design alsoprovides longer component life and excellent fuelconsumption.Caterpillar Electronic Ignition System (EIS)
Detonation sensitive timing protects the engine againstdetonation damage. Higher voltage and longer sparkduration mean easier starts, fewer misfires, andsmoother operation. Diagnostic codes help pinpointcylinder and component of interest. Spark plugmaintenance codes identify spark plug conditionEase of Operation
- Deep sump oil pan has a larger capacity for normal750-hour oil change intervals- High-strength pan and rails for excellent mounting andstability- Side covers on block allow for inspection of internalcomponentsFull Range of Attachments
Large variety of factory-installed engine attachmentsreduces packaging timeTesting
Every engine is full-load tested to ensure proper engineperformance.Gas Engine Rating Pro
GERP is a web-based program designed to provide siteperformance capabilities for Cat®natural gas enginesfor the gas compression industry.
