The certification means that the Cummins 2010 engine lineup for
on-highway applications meets the near-zero emissions levels required
for all engines manufactured in 2010, Cummins said in a statement.
The EPA regulations, which took effect Jan. 1, set nitrogen oxide
and particulate matter emissions levels of 0.2 grams and 0.01 grams per
Cummins will utilize selective catalytic reduction technology to meet the new standards.
“Our decision to use SCR technology has given us the ability to
provide customers with the most fuel efficient engines for on-highway
applications,” said Jim Kelly, president of Cummins’ engine business.
“We expect to see at least 5% fuel economy improvement for the ISX15
and up to 3% improvement for the midrange products,” Kelly said.
Cummins also said it will introduce its ISX11.9 engine later in
2010, targeted to customers in the vocational and less-than-truckload
The ISX11.9 is on target for limited production in mid-2010 with
full production commencing in late summer of 2010. Cummins said it will
submit necessary documentation for EPA 2010 certification for the
ISX11.9 later this year.
