GALVESTON, Texas--(BUSINESS WIRE)--

Cummins Inc. (NYSE:CMI) announced today that their GTA8.3SLB gas compression driver now meets the Environmental Protection Agency's proposed New Source Performance Standards (NSPS) for stationary spark-ignited engines. The new GTA8.3SLB meets the NSPS standard more than six months ahead of the target promulgation date of Jan. 1, 2008 for engines in 25-500 hp (19-373 kW) power bands.

Cummins GTA8.3SLB is rated at 175 hp (130 kW) and features a Simple Lean Burn configuration that meets the 2-gram Nitrogen Oxide (NOx), 4.0-gram Carbon Monoxide (CO) and 1.0-gram Non-Methane Hydrocarbon (NMHC) output-per-horsepower-hour EPA proposal while providing great performance and unsurpassed reliability through its simplicity. The engine also meets the Four Corners Bureau of Land Management 2-gram NOx requirements. The 8.3-liter inline 6 GTA8.3SLB provides 511 lb-ft (693 N-m) of torque at 1800 rpm and was designed for wellhead and related gas compression applications.

The GTA8.3SLB engine utilizes many of the same extremely durable internal components such as the block, crankshaft, camshaft and connecting rods used in Cummins C Series diesel engines. This parts commonality provides a distinct advantage for the operator in terms of the proven reliability and long life of the components, familiar servicing and parts availability.

Reliability of the GTA8.3SLB is further enhanced through the use of Cummins air/fuel ratio control, an Altronic CD200 electronic ignition and Woodward electronic governor. Moreover, through Cummins expertise in controlling the combustion process, the GTA8.3SLB meets the 2-gram engine-out level without the use of detonation sensors. And with the addition of an oxidation catalyst, the GTA8.3SLB is able to meet regional emissions standards, such as the State of Pennsylvania, where lower CO regulations are applicable.
