ATLANTA (October 5, 2009) -

Cummins Inc. (NYSE: CMI) launched the QSL9G gas compression driver for the oil and gas market today at the 2009 Gas Machinery Research Council (GMRC). The new QSL9G, rated 175 hp (130 kW) at 1800 rpm, is Cummins latest offering to meet the Environmental Protection Agency’s New Source Performance Standard (NSPS) 2011 regulations for stationary spark-ignited engines below 500 hp (373 kW).

Building on the successful performance of Cummins GTA8.3SLB natural gas and QSL9 diesel engines, the new QSL9G is a turbocharged and aftercooled rich-burn engine designed to meet the 2011 NSPS regulations of 1.0 gr/hp-hr Oxides of Nitrogen (NOx), 2.0 gr/hp-hr carbon monoxide (CO) and 0.7 gr/hp-hr volatile organic compounds (VOC). The QSL9G will also meet the Texas Commission on Environmental Quality (TCEQ) non-attainment requirement of 0.5 gr/hp-hr NOx.

The 8.9-liter QSL9G natural gas engine is parented from the diesel QSL9 engine, which has been operating in industrial applications for over a decade. In addition, the QSL9G shares many common components with the GTA8.3SLB and G8.3E engines, which simplifies the repowering of existing GTA8.3 designs.

The QSL9G has been developed specifically for the oil and gas market with scalable emissions technology to meet current emissions requirements as well as lower emissions requirements for the foreseeable future. The QSL9G is equipped with an electronic ignition, governor and air-fuel ratio controller, and utilizes many of the same heavy-duty internal components such as the block, crankshaft and connecting rods used in Cummins larger diesel engines.

“Being the leader in engine emissions technology means delivering the emissions solution that goes beyond the basic needs of the industry. Cummins goal for the stationary gas engine market is to deliver a total solution with technology that can meet changing emissions standards for the life of the engine,” said Mark Levett, Vice President and General Manager of Cummins High-Horsepower Engine Business. “Our continued success in the gas compression market is based on continuing to develop the right products with the right technology and having the people and infrastructure to support our customers better than anyone else in the field.”

“While emissions regulations are still changing at both the federal and local level, our customers’ requirement for a reliable and durable engine is a constant. The QSL9G is another step in Cummins strategy to be a leader in the oil and gas industry. We will continue to improve and develop new products that provide outstanding value and earn the business of new customers,” added Levett.
