Features at a Glance
- Engine Design
-
• Improved 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
- Emissions
-
Meets U.S. EPA Spark Ignited Stationary NSPS Emissions for 2007/08
- 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. Leanburn design also provides longer component life and excellent fuel consumption.
- Cat® Electronic Ignition System (EIS)
-
Detonation sensitive timing protects the engine against detonation damage. Higher voltage and longer spark duration mean easier starts, fewer misfires, and smoother operation. Diagnostic codes help pinpoint cylinder and component of interest. Spark plug maintenance codes identify spark plug condition
- Ease of Operation
-
• Deep sump oil pan has a larger capacity for normal 750-hour oil change intervals• Side covers on block allow for inspection of internal components
- Full Range of Attachments
-
Large variety of factory-installed engine attachments reduces packaging time
- Testing
-
Every engine is full-load tested to ensure proper engine performance.
- Gas Engine Rating Pro
-
GERP is a web-based program designed to provide site performance capabilities for Cat natural gas engines for the gas compression industry. GERP provides engine data for your site's altitude, ambient temperature, fuel, engine coolant heat rejection, performance data, installation drawings, spec sheets, and pump curves.
