This approach also ensures that the engine and aftertreatment system work together and that their useful life is equal to the life of the Ship. Since this work has already been completed, no further emission tests are required after Completion.
The design has been proven to meet all the emission requirements on the test bench and all different configurations of the design are already approved.
The schema-a approach means that Cummins will conduct tests in the presence of witnesses or Has cooperated directly with an imo-recognised agency before the system arrives at the Shipyard. In addition to the maintainability of the SCR system, the vanadium-based catalyst can be operated with fuels of up to 5000 ppm sulphur, so that customers can use the same quality fuels as they always do with Cummins Products.Ĭummins offers a pre-certified system using the so-called scheme a approach, eliminating the complexity of additional complex certifications in the shipyard and implementing the overall project in less time and cost-effectively. The service life of the catalysts is expected to be as long as the engine has been overhauled – an example of coordinating the maintenance intervals of the engine and post-treatment for low TCO due to minimal downtime.
The catalysts can be easily exchanged in a given time without the need for new or special Tools. The SCR system chosen by Cummins is fully maintenance-ready, D. "thanks to over 10 years of experience in using SCR with Cummins Motors in the road vehicles and industry segments, ship operators can be confident that their ship will be driven by an excellent product."Ĭummins was committed to providing the smoothest possible introduction of the new ship component for existing customers and Customers. "cummins engineers have undergone extensive testing to ensure the operational reliability, quality and reliability our customers expect from the brand," says Jim manhole, Executive director, Cummins Global Marine BUSINESS. In addition, flexible installation options Help to optimize total cost of ownership by reducing assembly effort in eight different configurations to meet virtually any customer Requirement. To minimize the total cost of ownership (tco) of the operator, Cummins optimized the liquid consumption of the diesel exhaust and coordinated the post-treatment maintenance intervals with the engine maintenance intervals to minimize downtime Reach. In many markets, Cummins Motors have been equipped with SCR technology since 2006 so that more than 1 million units are already in Use.
instead, Selective catalytic reduction (scr) is used to comply with the new emission regulations with consistent fuel Consumption. The proven engine architecture has not been changed. The first introduction of the QSK60 with a modular common rail fuel system (MCRS) in the marine market took place in the year 2008 and was an immediate success thanks to Industry-leading Reliability. (nyse: Cmi) has announced today the new engine package QSK60, certified in accordance with tier III of the International Maritime Organisation (imo), with lower emissions and improved warranty, which for many Various marine applications are available from commercial work vessels to luxury yachts.
