Diesel Technology Forum Launches Video Series

April 18, 2014

The Diesel Technology Forum is launching a 10-part video series highlighting the research, development and strategies used by leaders in clean diesel technology to produce near-zero emissions in new off-road engines and equipment. The series includes interviews with technology and business executives conducted at the recent 2014 CONEXPO CON/AGG convention in Las Vegas.

“This year marks a new era for construction, farm and other off-road diesel engines and equipment that are the essential tools to key sectors of our economy,” said Allen Schaeffer, executive director of the Diesel Technology Forum. “Manufacturers have met the challenge from the U.S. Environmental Protection Agency to virtually eliminate emissions of particulate matter (PM), or soot, and nitrogen oxides (NOx) in the fourth generation, or so-called Tier 4 Final emissions standards.

“There is no better example of innovation and achievement in clean, fuel-efficient technology than what is now available from diesel engine and equipment makers. Not only is the new generation of clean diesel technology 90 percent lower in emissions of PM and NOx compared to 1996 engines, but it is also provides the customer with advantages in the form of greater productivity and better fuel efficiency. This is truly amazing considering the vast numbers of types and sizes of machines and equipment that utilize this new advanced technology,” Schaeffer said.

In the first video of the series, Jennifer Rumsey, vice president of engineering for Cummins Engine Business, explains how Cummins developed its diesel engine technology through the Tier 4 Interim and Tier 4 Final stages to develop near zero emissions products. This included adding new components like a common rail high pressure fuel system for particulate control, exhaust gas recirculation, a variable-geometry turbocharger, a particulate filter and the selective catalytic reduction.

“The benefits that we see with our Tier 4 Final technologies are really about fuel efficiency and air quality,” Rumsey said.

Upcoming videos will feature other strategies in achieving the Tier 4 standards for other leading manufacturers including Bosch, Case Construction Equipment, Caterpillar, Deere and Company, FPT Industrial, Isuzu, Johnson Matthey, MTU America, Volvo Powertrain and Yanmar.
