Caterpillar is pleased to announce oil and gas specific product plans to meet upcoming US EPA Tier 4 emissions regulations that take effect in the year 2011 for products with power ratings above 130 kW (175 bhp). This important regulation will require emissions reductions of particulate matter (PM) by 90% and oxides of nitrogen (NOx) up to 50% beyond EPA Tier 3 standards. Caterpillar remains committed to lowering emissions to support sustainable development and will continue to deliver the reliability and durability oil and gas customers demand.

To develop a full product line of Tier 4 solutions, Caterpillar has undertaken the single greatest technology investment in company history. Caterpillar has been working directly with oil and gas customers to determine key requirements. Through this market research, tailored solutions have been created to reduce emissions, maintain or improve durability, minimize OEM equipment redesign costs, and lower owning and operating costs.

Caterpillar will make a significant transition to meet Tier 4 regulations through the integration of a suite of next generation emission reduction technologies to optimally meet and exceed requirements of oil and gas customers. This includes Tier 4 Interim solutions up to 1200 bhp across eight engine models.

In addition, and in direct response to the needs of petroleum customers, Caterpillar will offer Tier 4 Final ratings of the Cat® C18 ACERT (>751 bhp), C27 ACERT, and C32 ACERT products ranging in horsepower from 765 bhp - 1125 bhp. These engines are used for a wide variety of petroleum applications, including some of the most demanding in the industry - pressure pumping, cementing and well fracturing. These Tier 4 Final compliant engines will be available in 2010, more than four years earlier than required. This strategy will significantly lower engineering costs for customers and reduce overall environmental impact and fleet complexity.

All Tier 4 engines were designed with the same quality that customers expect from Caterpillar. In addition to validation for Cat machines and other commercial engines, these products are being validated specifically to petroleum applications in both the lab and the field to ensure reliability and durability are not compromised.

Caterpillar is specifically prepared to aid dealers and customers with the tools needed to succeed at Tier 4 and beyond. Through focused training, dedicated application resources, world class product support and a highly skilled dealer network, Caterpillar is committed to easing the transition for customers while reaching sustainable development goals.
