Cummins Inc. said Friday it has received U.S. Environmental Protection Agency certification for its heavy-duty and midrange 2010 engines — the heavy-duty big-bore ISX15 and midrange ISB6.7, ISC8.3 and ISL9 units.
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 brake-horsepower-hour, respectively.
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 markets.
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.
