Peoria, Illinois September 23, 2008 — Caterpillar is pleased to announce technology plans to meet upcoming US EPA Tier 4 Interim, European Stage IIIB and Japan MLIT Step 4 mobile non-road emissions regulations that take affect in the year 2011. These emission standards will require emissions reductions of particulate matter (PM) by 90% and oxides of nitrogen (NOx) up to 50% beyond EPA Tier 3/EU Stage IIIA standards.
Caterpillar® technology plans cover all Caterpillar industrial engine applications and regions subject to these emissions regulations. Less than 75 hp Tier 4 Interim compliant industrial engines, now in production, were announced in 2007. The engine emissions technologies represented in these plans will meet Caterpillar global industrial engine OEM customer needs for highly integrated, yet flexible engine systems.
Caterpillar previously achieved dramatic reductions in regulated engine emissions through our launch of ACERT® Technology for Tier 3/Stage IIIA. We continue our commitment to enabling our customers to be more sustainable in their operations. The technology we launch today establishes the foundation for virtually zero particulate matter non-road emissions by 2014. These reductions are coupled with the additional environmental benefit of fewer greenhouse gas emissions achieved through planned fuel efficiency improvements.
Utilizing ACERT Technology as a foundation, Caterpillar will add 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 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.
To provide additional customer value and further leverage successful platforms, Caterpillar will offer a new 7 liter engine designed specifically for Tier 4 Interim and future emissions compliance. In addition, the industrial C9 ACERT will feature increased displacement. These two developments will offer customers additional power choices in the very important 250-400 hp segment.
As Caterpillar leverages its suite of ACERT solutions, particulate reduction technology will include the use of advanced combustion technology, oxidation catalysts and diesel particulate filters with advanced regeneration systems that will optimize uptime, fuel efficiency and operator convenience. During the past 14 years, Caterpillar has produced over one million particulate aftertreatment devices. Caterpillar possesses the proven ability to apply its extensive particulate aftertreatment design and application experience to match the appropriate technology with the specific application to meet customer and OEM requirements, and optimize machine and engine applications.
A suite of NOx reduction technologies will be tailored to optimally meet varied customer requirements. Caterpillar non-road mobile industrial engines will not utilize selective catalytic reduction (SCR) for Tier 4 Interim regulations. In each case, Caterpillar has selected and implemented the technology that optimally satisfies customer needs based on the application and emissions regulations.
Caterpillar customers can expect Tier 4 Interim/Stage IIIB engines to continue to provide excellent power, response and durability as did Tier 3/Stage IIIA engines, with fuel efficiency improvements planned, says Hans Haefeli, Caterpillar Vice President responsible for industrial engines.
During the past decade, Caterpillar has developed an extensive understanding of the component systems, emissions, installation impact and packaging requirements for the Tier 4 Interim/Stage IIIB solution.
Caterpillar is ready to provide industrial customers with the broadest product range, 75-750 hp, the most extensive technology expertise, collaborative design processes, demonstrated system integration experience and unequaled product support. These technologies mark an important advance towards providing sustainable solutions for the world™s power needs.
