Features

Engine Design

โ€ข Improved reliability and durability โ€ข Ability to burn a wide spectrum of gaseous fuels โ€ข Robust diesel strength design prolongs life and lowers owning and operating costsโ€ข 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.

Catยฎ 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

โ€ข Deep sump oil pan has a larger capacity for normal 750-hour oil change intervalsโ€ข Side covers on block allow for inspection of internal components
