MAN Diesel & Turbo has announced that the MAN 32/44 Common Rail engine family (rated power: 3,600 – 12,000 kW) has received US EPA Certification, a requirement for all engines installed aboard US-flagged vessels.
Chuck Griffith, Sales Manager, MAN Diesel & Turbo, North America, said: “This certification is a significant step in our four-stroke, marine-engine strategy for the US market. The engine family has been certified US EPA Tier 2 for Category 3 engines and builds the foundation for us to introduce our US EPA Tier 3 for Category 3 product in 2016. This will allow US customers to benefit from the high power output and low fuel-consumption of our medium-speed, common-rail engines.”
US EPA Tier 3 is currently the final emissions tier for Category 3 (≥ 30L/cyl displacement) engines, and is similar to US EPA Tier 4 for Category 1 and 2 (< 30 L/cyl displacement) engines.
The US EPA certification process was initiated in response to demand from the American fishing industry. MDT has already received several orders within the United States for the engine, including that for an MAN 8L32/44CR engine to power a newbuilding trawler for Fishermen’s Finest, the U.S. fishing company.
32/44CR characteristics
MAN Diesel & Turbo’s common-rail engines are among the most technologically advanced in its portfolio with a segment-leading SFOC that significantly lowers emissions of soot and NOx over its complete operating range. The company’s CR engines have already established a solid presence in several marine segments globally.
Specifically, the MAN 32/44CR is characterised by:
• common-rail technology featuring optimised NOx vs. SFOC trade-off at every load point, independent of rpm
• a high power output: 600 kW/cyl for diesel-electric set-ups and CPPs; 510 kW/cyl for FPPs and dredgers
• low fuel-consumption of 172.4 g/kw-hr for diesel-electric and CPP set-ups, and the use of high-efficiency turbochargers.
MAN 32/44CR engines are suitable for a variety of applications including fishing, ATBs (Articulated Tug Barges), anchor handlers, offshore construction vessels, dredgers and drill ships.
