Recently, Mann Diesel & Turbo announced that its MAN 32/44 common rail engine (rated at 3,600-12,000 kW) has been certified by the US Environmental Protection Agency as a requirement for all engines mounted on US flag ships. .
Chuck Griffith, North American sales manager for Mann Diesel & Turbo, stated, "This certification is an important step in the company's four-stroke marine engine strategy. The engine has passed the US Environmental Protection Agency Tier 2 Class III engine certification, and This laid the foundation for our EPA Tier 3 Class 3 engine certification in 2016. This will help US users benefit from the high power output and low fuel consumption of our medium speed common rail engine."
The US Environmental Protection Agency Tier 3 is the ultimate emission requirement for the current Class 3 (≥ 30 L/cylinder displacement) engine, similar to the US Environmental Protection Agency's Tier 4 Class 1 and Class 2 (< 30 L/cylinder displacement) engine emissions requirements.
It is reported that the US Environmental Protection Agency certification process has begun to respond to the needs of the US fisheries sector. Mann Diesel & Turbo pointed out that the company has received several orders for the US to order the engine, including an order for the MAN 8L32/44CR engine for a new trawler built by Fishermen's Finest, Inc. The order is important because the order represents a breakthrough in the important US domestic fisheries sector for common rail engines.
Mann Diesel & Turbo pointed out that the common rail engine launched by Europe eight years ago has been characterized by low smoke and nitrogen oxide emissions and low fuel consumption, and has already established influence in several maritime fields around the world.
In particular, the MAN 32/44CR engine has a common rail technology that is interchangeable at each loading point, independent of speed, optimized NOx and fuel consumption rate, a high power output: diesel-electric configuration and adjustable pitch propeller (CPPs) power of 600 kW/cylinder; fixed-pitch propeller configuration with 510 kW/cylinder, dredger (ship type shipyard) and diesel-electric and adjustable pitch propeller (CPPs) configurations with high-efficiency supercharger fuel The consumption will be as low as 172.4 g/cylinder.
Mann Diesel & Turbo stated that its 32/44CR engine is suitable for a wide variety of vessels, including fishing boats, articulated tow barges, anchor chain handling, offshore construction vessels, dredgers and drilling vessels.
