Cummins QSC8.3 EPA Tier 3 Marine Engine Now Available

Boat builders will be able to deliver the latest clean-diesel technology with no additional engineering, say the engine manufacturers. The new certification is met with in-cylinder combustion optimization requiring no additional emissions hardware.

The engine model QSC8.3 joins the QSB6.7, released last year, and the QSL9 and QSM11, which will be available later this year, to round out Cummins complete lineup of 
Tier 3 certified clean diesels for the marine market.

Advanced technology and engineering expertise gained while meeting the world’s cleanest emissions regulations in all diesel markets allows Cummins to use the right technology to meet EPA standards. Marine EPA Tier 3 calls for a 20 percent reduction in nitrogen oxides (NOx) and hydrocarbons (HCs), and a 40 percent reduction in Particulate Matter (PM). For EPA Tier 3, Cummins engineering team duplicated the Tier 2 ratings to maintain the same vessel performance with comparable fuel economy.

Like all Cummins engines, the EPA Tier 3 QSC8.3 is backed by Cummins global support network for parts and service.
