Cleaner Cummins QSC8.3 released
EPA Tier 3 certified QSC8.3 ready for summerThe Cummins QSC8.3 (490-600hp) marine engine is now Tier 3 certified and will be available in Australia for the new boating season. The 600hp variant is fitted to the Grand Banks 52 Aleutian RP in the accompanying photo in previous Tier 2 compliant mode.
As U.S. Environmental Protection Agency (EPA) Tier 3 marine regulations come into effect in January 2014, boat builders will be able to deliver the latest clean-diesel technology with no additional engineering.
The new certification is met with in-cylinder combustion optimisation requiring no additional emissions hardware.
The QSC8.3 joins the QSB6.7 (230-550hp) released at the recent Sydney boat show, and the QSL9 (285-405hp) and QSM11 (300-715hp), which will be available later this year. That will round out Cummins' 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, the American engine maker says.
Marine EPA Tier 3 calls for a 20 per cent reduction in nitrogen oxides (NOx) and hydrocarbons (HCs), and a 40 per cent 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. The engine is uses for Zeus pod drive applications as well as traditional shaft drives.
