Environmental Benefits of EPA's New Tier 4 Final Standards Highlighted At CONEXPO CON/AGG 2014 Convention

"Clearly the big driver for Tier 4 regulations is environmental and health benefits and we'll see a 90% reduction in NOx and particulate emissions compared to Tier 3 with our Tier 4 final engines." - Jennifer Rumsey, Cummins Engine Business

LAS VEGAS, March 7, 2014 /PRNewswire/ -- The environmental and health benefits resulting from the Environmental Protection Agency's new Tier 4 Final standards have been one of the major focuses of attention at North America's largest construction and farm equipment event – the CONEXPO CON/AGG 2014 convention this week at the Las Vegas Convention Center.

Leading manufacturers of advanced diesel technology were unveiling and showcasing their new Tier 4 Final engines and equipment at the convention, which has attracted more than 125,000 visitors who are seeing several hundred new machines on display throughout the 2.3 million square foot exhibit area.

The Tier 4 Final standards became mandatory for new off-road diesel engines and equipment in the U.S. at the beginning of 2014.  The goal is to reduce exhaust gases from diesel powered equipment by requiring significant emission reductions of particulate matter (PM), or soot, and nitrogen oxides (NOx).

New Tier 4 Final Equipment Has Lower Emissions & Higher Efficiency
Several leading manufacturers at CONEXPO CON/AGG 2014 highlighted the benefits of the new construction, industrial and farm equipment in decreasing PM and NOx.  In addition, many manufacturers were able to improve the efficiency of the new machines while also meeting the emissions standards.

"Clearly the big driver for Tier 4 regulations is environmental and health benefits and we'll see a 90 percent reduction in NOx and particulate emissions compared to Tier 3 with our Tier 4 Final engines," said Jennifer Rumsey, the Vice President of Engineering for Cummins Engine Business.  "But beyond that customers are also going to realize the benefit of lower fuel usage with these engines.  So they'll see a significant reduction in their operating costs which with the cost of diesel fuel today can be very substantial."

"We're Able to Burn Every Drop of Fuel Instead of Sending It Out As Particulate Matter"
David Hahn, the Manager of Power Train PST for Volvo Construction Equipment explained: "We're able to burn every drop of fuel inside the engine instead of sending it out as particulate matter which translates into a five percent fuel savings across the board on the Tier 4 Final engines, which translates into a five percent cost savings for end user."

"The Long Term Benefit is Much Lower Emissions for Society"
"The long term benefit is much lower emissions for society," said Doug Mihelick, the Technical Sales Manager of the Engine Division at Caterpillar.  "As older equipment ages out more of these new machines are going to come into the population and society is going to benefit from the cleaner air.

"In addition our customers benefit because every one of these Tier 4 products that our customers buy have better fuel efficiency, better machine productivity.  So there are multiple benefits to our customers, to the markets those customers serve, and to society as more and more of these tier 4 products get out into the field."

New Diesel Technology Will Have Improve Up Time & Lower Operating Costs
Doug Laudick, the Manager of Product Planning at John Deere noted:  "Some of the advantages of the clean diesel technology are going to be clean diesel, lower emissions and that's the primary goal we're all shooting for.  With that though, will be enhancements and improvements in performance, improved up time and lower operating costs in the form of better fluid economy."

Everyone Benefits From Cleaner, More Efficient Vehicles
Paul Mercurio, the Diesel Marketing Manager for Bosch North America, said the new Tier 4 Final technology will spur further advancements.
"As we move forward everyone will benefit from this because vehicles will be cleaner, they'll be more efficient, they'll be more powerful and will also help the technology grow throughout the industry," Mercurio said.

Diesel Advancements Have Improved Aftertreatment & Engines
Douwe Hilarius, the Operational Marketing and Communications Manager for FPT Industrial explained:
"The diesel engine has evolved through the years and has seen a lot of changes in the last two or three decades. We've seen the introduction of new technologies not only on the after treatment but also on the engine itself."

If A Diesel Engine Can Fit, It Can Run Anything More Efficiently
"The versatility of the diesel engine is exceptional. If it can fit it will run anything and it will run longer and it will run more efficiently," said Justin Rupar, the Business Unit Manager for the Industrial Engine Division at Yanmar.

Added Bob Links, the OEM Sales Manager for Isuzu Motors of America:  "We work with our customers - they'll call us with an application and we'll tailor an engine just to their needs."

Even Small Efficiency Improvements Can Provide Major Savings for Operators
Scott Woodruff, the Director of Industrial Sales at MTU America Inc. explained: "For many applications in an off-highway market fuel consumption is very expensive and becomes typically the driving cost of operating an off road vehicle.   By improving fuel consumption as little as one to two percent could represent thousands and tens of thousands of dollars per year to an operator in savings. It really has opened a new frontier of diesel engine technology."

New Concept of Total Fluid Economy Emerges At CONEXPO 2014
Mike Osenga, the President of Diesel and Gas Turbine Publications offered insight into new calculations by manufacturers and end users.

"I think one of the interesting trends we've seen this week at CONEXPO is the concept of total fluid economy coming into the market," Osenga said.  "Everybody is always talking about fuel economy.  Now we're talking about total fluid consumed by a diesel engine.  DEF or diesel exhaust fluid is now being factored in with diesel fluid consumption as a differentiator in different types of engines."
