built for the next generation Cat Tier 4 FINAL, STAGE IV TECHNOLOGIES FOR INDUSTRIAL ENGINEs 速
PROVEN PERFORMANCE With more than 15 million working hours on tens of thousands of units since the Tier 4 Interim product introductions, you can be confident in the quality and value of your Cat Tier 4 Final investment. At Caterpillar, we know you’re under constant pressure to do more work at a lower total cost with less environmental impact. Our Tier 4 Final, Stage IV solutions help you do that. We redesigned the industrial engine product line at Tier 4 Interim, Stage IIIB with space claim factored in for Tier 4 Final, Stage IV. Our decades of innovation and expertise work on your behalf. The result is a new generation of engines that meets your high expectations for reliability, performance, fluid efficiency and component life, while producing significantly fewer emissions.
Engines and systems integration boost power, save fuel Caterpillar engine designers work collaboratively, using advanced modeling and analysis tools to integrate components, systems, electronics and aftertreatment technologies. Our integration experience allows us to optimize power, fuel economy and emissions reduction.
Integrated manufacturing improves quality Our position as the largest vertically integrated manufacturer in our business gives us the power to build premium-quality products. We integrate manufacturing advancement into engine designs and use common production processes across the manufacturing base. As a result, we can deliver exceptional quality right from the start.
Testing and validation increases reliability The newest generation of Cat engines has been subjected to the largest testing and validation program in Caterpillar history. Powerful design tools allow sophisticated simulation and analysis, and a comprehensive fieldtesting program provides real-world validation.
This brochure will use the terminology “Tier 4 Final, Stage IV” and “Tier 4 Interim, Stage IIIB” to refer to U.S. Environmental Protection Agency and European Union emission standards. Some other highly regulated markets adopt these standards, such as Canada and Japan. 2

Canada, Japan, and the European Union.
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 1 (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. From Tier 3, Stage IIIA (2006) to Tier 4 Interim, Stage IIIB (2011), emissions standards required a 90 percent reduction in PM and a 50 percent reduction in NOx emissions. The next phase of emissions standards, called Tier 4 Final, Stage IV in the U.S., take effect in 2014. Compared to Tier 4 Interim, Stage IIIB levels, Tier 4 Final, Stage IV standards require an additional 90 percent reduction in NOx, taking PM and NOx emissions to near-zero levels. * Engines rated 56–130 bkW (75–175 bhp) were required to meet Tier 4 Interim, Stage IIIB standards in 2012 and will meet Tier 4 Final, Stage IV regulations in 2015. Engines rated >560 bkW (750 bhp) met Tier 4 Interim standards in 2011 and will meet Tier 4 Final regulations in 2015 (U.S. EPA only). Standards differ by power category.

Next Generation Fuel System Options As a key component of Cat Tier 4, Stage IIIB or Stage IV technology, injection timing precisely controls the fuel injection process through a series of carefully timed microbursts. This injection timing provides more control of combustion for the cleanest, most efficient fuel burn. To maximize customer value, Caterpillar engineers specified fuel systems based on the power and performance demands for each engine. High Pressure Common Rail Fuel Systems with full electronic injection improve precision and control that boost performance and reduce soot for the C3.4B, C4.4 ACERT, C7.1 ACERT and C9.3 ACERT. Advanced MEUITM-C injector platforms handle increased injection pressures and more precise fuel rates. These durable injectors enhance responsiveness while controlling soot in the C13 ACERT, C15 ACERT, C18 ACERT, C27 ACERT and C32 ACERT.

Cat NOx Reduction System The Cat NOx Reduction System (NRS) captures and cools a small quantity of exhaust gas, then routes it back into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions. The result of more than a decade of Caterpillar engineering research into this technology, the Cat NOx Reduction System is designed to be the most reliable system of its type.

Aftertreatment Technologies Cat aftertreatment components include:
DOC/DPF
Diesel Oxidation Catalyst (DOC) The DOC uses a chemical process to convert regulated emissions in the exhaust system. The DOC does not require maintenance because it is a “flow-through” device and the hydrocarbon does not get trapped in the component.
Active and passive regeneration Cat Regeneration System is automatic SCR
Diesel Particulate Filter (DPF) A DPF traps additional particulate matter that’s carried in the exhaust stream, preventing it from being released into the atmosphere. Inside the DPF, particulate matter, sometimes referred to as “soot,” is trapped until it is oxidized during regeneration. A “No DPF” aftertreatment package (which meets emission standards) is available on certain platforms. Selective Catalytic Reduction (SCR) The SCR system consists of a SCR catalyst, Ammonia Oxidation catalyst and the Pump Electronics Tank Unit (PETU). This system uses a small amount of diesel exhaust fluid (DEF) to convert NOx emissions in the exhaust into nitrogen and water.

Tier 4 Final, Stage IV engineering minimizes additional maintenance and maximizes efficiency to lower operating costs. This reduction is due to improvements in fluid efficiency and serviceability that offset the costs associated with aftertreatment maintenance. Testing and analysis results, along with customer feedback, show that total operating costs have been reduced.
