Caterpillar® has announced 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 2011 and 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.
The new plans cover all Cat industrial engine applications and regions subject to these emissions regulations. Utilizing ACERT Technology as a foundation, they 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.
Cat 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 250-400 hp segment.
As Cat 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.
A suite of NOx reduction technologies will be tailored to optimally meet varied customer requirements. Cat non-road mobile industrial engines will not utilize selective catalytic reduction (SCR) for Tier 4 Interim regulations.
