G3408C
G3408C Low Emissions Gas Compression Engine
DESCRIPTION
Tough and durable, built on the industry-standard G3400 platform bring maximum uptime and low operating cost to your operation. G3408C engines meet the most demanding continuous duty gas compression applications with virtually no unscheduled downtime.Ideal applications for G3408C engines include gas lift, gas gathering, and wellhead gas compression. Cat G3408C gas engine. Ratings: 317 bkW (425 bhp) @ 1800 rpm are NSPS site compliant capable with customer-provided aftertreatment or available for non-regulated areas.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.
