MAN 32/44CR receives EPA certification

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 U.S. 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 U.S. customers to benefit from the high power output and low fuel-consumption of our medium-speed, common-rail engines.”

EPA Tier 3 is currently the final emissions tier for Category 3 (≥ 30L/cyl displacement) engines, and is similar to EPA Tier 4 for Category 1 and 2 (< 30 L/cyl displacement) engines.

MAN Diesel & Turbo initiated the EPA certification process in response to demand from the American fishing industry. The company has already received several U.S. orders for the engine, including one for an MAN 8L32/44CR engine to power a newbuilding trawler for Fishermen’s Finest. The order was a breakthrough for the CR engine in the important, U.S. domestic-fishing segment (see earlier story).

Since being introduced in Europe eight years ago, the CR engines have consistently proven their reliability and durability within the fishing industry and are known for their excellent fuel efficiency and low operating costs. They are among the most technologically advanced in MAN Diesel & Turbo’s common-rail engines are its portfolio with a segment-leading SFOC that significantly lowers emissions of soot and NOx over the complete operating range.

The MAN 32/44CR is characterized by:

  • common-rail technology featuring optimized 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 dredges
  • 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, dredges and drill ships.
