Paris, France April 20, 2009 -- Caterpillar today introduced the Cat^® C7.1 ACERT^™ and C9.3 ACERT^™, the two newest members of the forthcoming Cat^® Tier 4 Interim/Stage IIIB diesel engine lineup, at stand #J003 in hall 5B at Intermat in Paris Nord-Villepinte.  

Designed for construction, material handling and other industrial applications, the new midrange models cover the critical horsepower band from 175 to 440 hp (130 to 328 kW). These new engine platforms produce fuel consumption improvements of up to 5% compared to existing Tier 3/Stage IIIA engines. Fuel economy improvements are dependent upon and subject to application, ratings and operating conditions. 

 When completely unveiled, the Cat Tier 4 Interim/Stage IIIB industrial engine lineup will include over twenty models from 11-1200 hp (9-895 kW).

The two new engines join the previously announced Tier 4 Interim/Stage IIIB platforms including: 

        
In addition to the Tier 4 Interim/Stage IIIB engines listed above, the Cat industrial engine line up offers a comprehensive range of engines from 11-6500 hp (9-4920kW).

Utilizing ACERT^™ Technology as a foundation, Caterpillar added next generation turbo charging, advanced electronics, advanced fuel systems, particulate aftertreatment systems and a suite of NOx reduction technologies to provide tailored emissions solutions to industrial engine Original Equipment Manufacturer (OEM) customers. Through years of proven results with ACERT Technology, Caterpillar has provided the broadest range of emissions technology solutions in the industry with a full range of fuel system, engine system, aftertreatment, machine system design and integration capabilities. 

These new engine platforms have been developed by the world’s largest equipment maker and benefit from the Caterpillar legacy of deep engine and OEM machine integration experience. Caterpillar has chosen integrated technologies that maximize customer value across the engine line and has designed these new industrial engines to satisfy specific customer needs.

In order to maximize the value of Tier 4 Interim/Stage IIIB ACERT engines, Cat has been conducting Tier 4 integration workshops with OEMs.  The collaboration process provides great benefits for OEM partners including detailed packaging and installation data as well as direct interaction with Cat dealer and factory technical experts. These collaborative efforts are integral to the Cat New Product Introduction (NPI) process for obtaining voice of the customer requirements very early in the product design and development stage which helps minimize the design time for new product installations.

As with all Cat Tier 4 Interim/Stage IIIB compliant engines, these engine platforms utilize the full complement of ACERT Technologies to achieve a significant 90% reduction of Particulate Matter (PM) and a 45% reduction of Oxides of Nitrogen (NOx).

Backed by the most extensive dealer network in the world, the new engines provide customers with the best choice for their most demanding industrial applications.

Cat industrial engines provide reliable power for original equipment manufacturer’s applications that are produced and operated around the globe.
