What Tier 4 Final Emissions Really Means

December 30, 2014 at 3:57 PMRing Power

Since 1996, a “tiered” series of emissions regulations has been in effect, establishing progressively stringent standards for allowable levels of oxides of nitrogen (NOx) and particulate matter (PM) released into the environment by new off-road and non-road diesel engines and equipment.

Essentially, Tier 0 engines are unregulated and most often mechanically rather than electronically controlled; Tier 1, Tier 2, and Tier 3 engines include technologies that have become increasingly sophisticated with each successive generation, using electronic engine controls, higher injection pressures and turbocharging systems to meet the emissions standards at each level.

The Tier 4 standards currently in force were actually initiated in 2008, with a goal of reducing PM and NOx emissions to a level 50-96 percent lower than the existing generation of diesel engines by 2015. A transitional step – Tier 4 Interim – was introduced in 2011, which required substantial reduction in PM while allowing for flexibility in lowering NOx. Tier 4 Final, which went into effect earlier this year, has tightened the standards for further reductions in NOx and hydrocarbon (HC) emissions.

To meet current emissions standards, Caterpillar and many other manufacturers have incorporated selective catalytic reduction (SCR) technology into their engine and equipment design. As a result, Cat dealers have had to learn how to service and maintain the innovative new systems and componentry that comprise this new technology.

For example, open crankcase ventilation filters (OCVs) need to be serviced or replaced periodically and diesel particulate filters (DPFs) need to be cleaned at regular intervals by a qualified technician. You may also find that belts, hoses, radiators and alternators require more frequent inspection due to the higher temperatures and operating pressures.

In addition, Tier 4 engines require ultra-low sulfur diesel fuel (ULSD) and CJ-4 low ash oil for a cleaner burn. Engines and equipment outfitted with SCR technology have a separate, on-board storage tank to hold the diesel exhaust fluid (DEF) used in after-treatment, which in turn requires special handling – and special mention here.

Tier 4 equipment owners need to understand the importance of working only with reliable vendors when purchasing DEF; and of storing their own supply in a cool, dry, well-ventilated area, out of direct sunlight. Manufactured to strict standards, DEF is a carefully blended solution of 32.5 percent high purity urea and 67.5 percent deionized water. Because temperature and time inevitably alter its concentration, DEF storage containers must be clearly dated. Contamination also affects concentration, which means storage containers must be clean and used exclusively for DEF.

 

The good news

By and large, meeting Tier 4 Final emissions standards is the responsibility of the engine manufacturers and equipment dealers. When the time comes to purchase new equipment, all you need to know is that your equipment dealer is prepared to provide the new maintenance practices required by the new components and technologies that come standard on Tier 4 Final engines.

Until then, you need not worry about Tier 4 Final at all. Tier 4 emissions requirements apply to new products only – not retroactively to any existing equipment – and at present there is no federal requirement to upgrade any existing engine to meet the new standards. Furthermore, Ring Power will be able to sell Tier 3 engines and equipment until the inventory is depleted and to service all previous generations indefinitely.

However, if your work involves bidding on governmental or public sector contracts, owning Tier 4 machines may give you a competitive edge. In that case, Ring Power has the inventory and expertise to assist you before, during and after your purchase – including Tier 4 classes for owners and operators – to help ensure you get the improved fuel efficiency, power and performance promised by the new emissions reduction technology.  

You are in good hands

Ring Power’s staff of training instructors and technical communicators have attended all of the Tier 4 training programs required by Caterpillar and are well prepared, not only to perform troubleshooting, maintenance and repair on Tier 4 Final engines, but also to instruct and train the service technician team.

Ring Power’s training department offers rigorous, ongoing Tier 4 Final training to bring service technicians up to speed with respect to the new, lower-emissions technology across all Ring Power equipment divisions. Any new machine – not just Cat, but any type, make or model of construction equipment, generator, air compressor, crane or forklift – that has a compression ignition diesel engine must now comply with Tier 4 Final regulations. To that end, Ring Power also requires all service technicians to enroll in the online curricula and hands-on training offered by their respective manufacturers.

 

The real bottom line

Although it sometimes seems a bitter pill to swallow, we need to remember that stricter emissions regulations were not imposed to punish companies that do off-road work or suppliers of off-road equipment. Every on-road vehicle has had to conform and comply, too. And, in the end, we all will be better off for it.

According to the EPA, reducing these emissions will annually prevent 12,000 premature deaths, 8,900 hospitalizations and one million workdays lost by the year 2030. Our children and our children’s children will thank us.

Caterpillar Receives Tier 4 Interim Certification for Non-Road Construction Equipment

September 20, 2010 at 8:57 AMRing Power

New Cat®C13 ACERT™ and C15 ACERT™ engines feature integrated design and provide improved fuel efficiency and productivity for next generation machines. CATERPILLAR C13 ACERT Engine Now Tier IV Interim Certified

C13 ACERT anda C15 ACERT engines have received the United States Environmental Protection Agency’s (EPA) Tier 4 emissions certification. The engines are the latest to receive certification in the 130 – 560 kW power category.

The C13 ACERT and C15 ACERT in addition to the previously announced certified C9.3 ACERT engine families will power a number of Cat products including mid-range track-type tractors, motor graders and hydraulic excavators in a wide variety of customer applications. Additionally, the C9.3 ACERT engine and its 13- and 15 liter counterparts are offered in several configurations and ratings for use by customers in the industrial, agriculture and petroleum markets.

"Our Tier 4 focus is not just about emissions – it is about the customer, as well" said Marketing and Product Support Vice President, Steve Gosselin. "Our ultimate goal is to exceed expectations by developing products that are more efficient, add more customer value and reduce emissions without sacrificing performance."

It is projected that Caterpillar will accumulate nearly one million hours of testing on Tier 4 Interim//Stage IIIB engines and machines by the end of 2010.

What is e3 and how will it reduce your farm tractor's emissions?

August 30, 2010 at 9:01 AMRing Power

The e3 system is AGCO's brand for selective catalytic reduction or SCR. AGCO introduced e3 before the 2011 Tier 4 regulation, because there was a market demand for powerful and fuel-efficient agricultural tractors. The exhaust gas recirculation or EGR optione3 emissions reduction will remain until 2011, at which time it will no longer be in compliance, and production will end.

Energy: Since e3 equipped engines deal with the regulated pollutants after the exhaust gas has left the engine, these engines create more power. This is after-treatment.

Economy: When e3 was introduced, AGCO and Challenger Tractor advertised up to 15% savings versus competitive (tier 3, EGR) engines. In fact, testing was completed at the Nebraska Test Lab and the results (made public in December of 2009) showed that e3-equipped tractors save up to 17% over comparable tractors.

Ecology: In current Tier 3 products, e3 reduces particulate matter by up to 70% and brings the NOx emissions to near Tier 4 interim levels.

Ring Power Launches New Tier 4 Website

August 20, 2010 at 4:19 PMRing Power

Ring Power Is Your Guide to Understanding EPA Tier 4 Emissions Regulations Ctaerpillar Egine Tier 4 Compliance Technology

Ring Poweralways strives to keep our customers informed and up to date with the latest information pertaining to you. That’s why we’ve launched a brand new website explaining the United States Environmental Protection Agency’s Tier 4 emissions regulations and what it means for you, the business owners, customers and hard workers. Ring Power wants to help educate our heavy construction equipment and power systems customers on this detailed new regulation so that they can be informed to make the best business decisions possible. It is always our goal to serve you. Please read for more information on Tier 4 below and then visit our new website at http://emissions.catdealer.com/ringpower.

The United States and European Union (EU) are implementing significant regulations that mandate the lowest emitting non-road equipment in history. Canada and Japan are expected to release similar regulatory programs yet this year. These regulations, which are known as U.S. Tier 4 // EU Stage IIIB/IV, will result in non-road equipment approaching near-zero emissions of particulate matter (PM) and oxides of nitrogen (NOx).

Transition to these standards is challenging for non-road equipment manufacturers. For Caterpillar alone, hundreds of complex products with unique and challenging application spectrums must be re-engineered to accommodate the lower emitting engines being developed to meet these standards.

Regulators recognize the challenge and the difficulty non-road equipment manufacturers would face if they had to introduce all of their new lower emitting products on one particular date. To address these transition challenges, the U.S. Environmental Protection Agency (EPA) has allowed for implementation of the upcoming emission standards in two phases: Tier 4 Interim and Tier 4 Final. Tier 4 Interim is effective 1 Jan 2011 for 130-560 kW non-road engines and 1 Jan 2012 for 56-130 kW non-road engines. Tier 4 Final emission standards apply after the 2014 model year. The EU’s Stage IIIB and Stage IV emissions levels and regulatory dates are essentially the same as EPA’s.

In addition, under its Transition Program for Equipment Manufacturers ("TPEM," which is commonly known as the "flex" program), EPA also allows equipment manufacturers to continue to introduce equipment powered with engines meeting prior Tier emission requirements for a certain limited percentage of their overall production volumes during the Tier 4 timeframe. The EU also has a "flex" transition program, as well as a unique "sell off" program, both of which allow equipment manufacturers to continue selling prior Tier machines in order to allow for a smooth transition to the more stringent EU emission standards. These transitional programs are calculated into the environmental benefits regulators forecast when developing these programs.

Caterpillar has a robust Tier 4 introduction plan, which is structured to transition from Tier 3 to Tier 4 products in a smooth and orderly fashion utilizing a variety of the transitional tools provided in the regulations in order to maximize value to you, our customers.
