Detroit Diesel Corp. has received EPA certification for its 12.7- and 14.0-liter Series 60 on-highway engines.
The Series 60 engine is fully certified to the new 2.5 g/hp-hr NOx + NMHC standard and does not require an after-treatment device of any kind, according to the engine company.
In addition, two different families of the Series 50 urban bus engines have received emission certification.
Detroit Diesel is the only manufacturer to have both diesel and natural gas urban bus engines emission certified and available, the company said. Detroit Diesel has also submitted a certification application for a Series 50 urban bus engine equipped with a particulate filter. Once certified, this will be the only heavy-duty diesel engine certified to California's stringent particulate standards.
"As we had previously announced, the Series 60 will be equipped with Exhaust Gas Recirculation (EGR)," said Mark Bara, senior vice president of on-highway engines. "During the week of Oct. 8, the new tooling and test equipment was installed." He said the company was to have begun a comprehensive training program Monday.
The Series 60 engine with EGR offers truckers the best combination of a popular and proven product that is fully certified to the new standards.
The Series 60 engine with EGR requires no changes in maintenance procedures and recommended oil change intervals remain as they were. In fact, with 8 million miles of testing to date, the wear rates of piston rings and cylinder liners of the EGR Series 60 engines are proving to be much reduced compared to previous engines without EGR. Cylinder kit wear has been significantly reduced, which should result in even longer life to overhaul than the current Series 60, according to the company.
There are more than 650,000 Series 60 engines in operation.
The Series 60 with EGR features a new low-profile gear train and other lighter-weight components to offset the weight increase of the EGR components. The EGR Series 60 engine actually weighs 65 pounds less than the non-EGR version
