Caterpillar Inc. has announced today that its C9.3 ACERT engine
has received the United States Environmental Protection Agency’s
(EPA) Tier 4 emissions certification and European Union (EU)
emissions type approval. The C9.3 ACERT is the first Caterpillar
non-road engine to receive emissions certification in the
130–560kW power category.
“We started this process by listening to our customers and
identifying what they want in a world class machine,” said Tana
Utley, Caterpillar vice president and chief technology officer.
“Our legacy, over the past 85 years, has been to develop and
deliver successful technology innovation, driven by our focus on
meeting our customer needs and striving to make them successful.”
Interim Tier 4/Stage III B emissions regulations begin January
1, 2011 for 130-560 kW engines and require a 90% reduction in
diesel particulate matter (PM) and a 50% reduction in nitrogen
oxide (NOx) from previous Tier 3/Stage IIIA requirements.
ACERT is an advanced combustion technology that uses a
building-block approach for reducing emissions that is based the
integration of key systems technologies. The C9.3 ACERT engine
family 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 is being offered in several configurations and
ratings for use by customers in the industrial, agriculture, and
petroleum markets.
“As the global industry leader in construction equipment and
commercial engine businesses, our intent is to fully utilize our
expertise to develop and deliver products that will be more
productive and fuel efficient, said Gary Stroup, vice president of
the company’s Large Power Systems & Growth Markets Division.
“Feedback from customers operating our pilot machines and
commercial products powered by Cat engines has been
extremely positive. They’ve expressed a preference for the Tier 4
machines in their fleet.”
By the time Tier 4 Interim/Stage IIIB products reach
customers, the Caterpillar Tier 4 validation programme will have
accumulated nearly one million hours of operation making it the
most extensive validation effort in Caterpillar history.
