Cat Tier 4 Interim/Stage IIIB Technologies
Advancing Technology: Building Customer Value
With decades of diesel engine innovation and expertise behind us, Caterpillar takes another critical step into the future with Cat® Tier 4 Interim/Stage IIIB technologies.
Successful businesses know they must meet customer expectations today as well as work toward the emerging needs of the future. Leaders are integrators—not just of engine systems, but of industry-best practices, service and support and sustainable value.
The Next Phase in Emissions Reduction
Cat Tier 4 Interim/Stage IIIB engines meet tough emissions standards and deliver the performance and efficiency that successful businesses demand. Like all manufacturers of diesel engines, Caterpillar is required to deliver engines that meet government emissions standards that are being phased-in throughout the United States, Canada, Europe and Japan.
Cleaner Fuel & Oils
Also part of the upcoming emissions standards, industry technology requires ≤15 parts per million (mg/kg) Ultra Low Sulfur Diesel Fuel (ULSD) for use in Tier 4 Interim/Stage IIIB engines. In Cat engines, not only will ULSD need to be used, but also low sulfated ash oils. These cleaner fuels and oils will help reduce ash and maintain service intervals, contributing to low emissions and reduced operating costs. The new Cat engines will also have B20 biodiesel capability, adding even greater sustainability where desired or required.
Emissions standards have been systematically reducing levels of Particulate Matter (PM) and Oxides of Nitrogen (NOx) since 1996 when the first standards went into effect. From Tier 1/Stage I (1996) levels to Tier 3/Stage IIIA (2006), emissions standards required an approximate 65 percent reduction in PM and a 60 percent reduction in NOx.
The next phase of emissions standards, called Tier 4 Interim in the U.S. and Canada and Stage IIIB in the European Union, take effect in 2011. Compared to Tier 3/Stage IIIA levels, Tier 4 Interim/Stage IIIB standards require a 90 percent reduction in PM and a 50 percent decrease in NOx. Tier 4 Final/Stage IV standards, which will become effective in 2014, reduce NOx by an additional 80 percent, taking PM and NOx emissions to near-zero levels.
Committed to Customer Success
Caterpillar equips every Tier 4 Interim/Stage IIIB engine with ACERT™
Technology with an ideal combination of electronic, fuel, air and after-treatment components, based on engine size, the type of application and the geographic location in which it will work. Applying technologies systematically and strategically optimizes them to meet our customers' high expectations for productivity, fuel efficiency, reliability and service life. The right technology fine-tuned for the right application results in:
Improved Fuel Efficiency: Up to 5 percent improvement in fuel efficiency
Power and Performance: Integrated design boosts power and performance across applications
Reliability: Through commonality and simplicity of design
Maximized uptime and reduced cost: With world-class support from the Cat Dealer Network
Long Life: Cat durability and long life to overhaul
Minimized Impact: Of service and maintenance on operating costs
Smooth Transition: Design and modular after treatment pave the way for a smooth transition to Tier 4 Final/Stage IV solution. No additional space required.
Reduced Emissions: Up to 90 percent reduction in particulate matter (PM) and 50 percent reduction in Oxides of Nitrogen (NOx)
