Detroit Diesel Corp. has received EPA certification for its 12.7 and 14.0 liter Series 60 on-highway engines, the company said.

The Series 60 engine will be equipped with Exhaust Gas Recirculation (EGR) equipment and does not require an after-treatment device.

"During the week of Oct. 8, the new tooling and test equipment was installed. We will begin a comprehensive training program for our production workforce starting Oct. 14th," said Mark Bara, senior vice president - On Highway Engines.

The Series 60 engine with EGR requires no changes in maintenance procedures and recommended oil change intervals remain as they were, the company said.
