Cummins Introduces QSB7 Marine Auxiliary Engine
Cummins Inc., a manufacturer of diesel engines for the commercial marine industry, is pleased to announce the latest addition to the Quantum Series product line and the company’s newest marine auxiliary engine, the QSB7-DM. The Quantum Series 6.7 liter engine was designed for industry-leading reliability, durability and the low cost of ownership marine operators have come to expect from Cummins.
“Operators can feel confident knowing Cummins developed a marine engine based on an existing base engine that has proven successful in demanding industrial and power generation applications since production began in 2007,” says Cummins Chief Engineer – Commercial Marine, Mike Aufdermauer. Cummins is looking forward to the first QSB7 marine genset installation for Weeks Marine of Cranford, New Jersey and Covington, Louisiana in late 2011. A radiator-cooled generator set will be installed on the BT105 floating living quarters barge and will run continuously throughout the duration of the 12-month field test. Supporting dredging personnel, the barge will operate between Panama City and the tip of Texas in the Gulf of Mexico.
With prime power ratings from 98 to 210 kW, the QSB7-DM is ideal for ship’s service and emergency genset power. All ratings are IMO Tier II and EPA Tier 3 certified, plus 50 Hz ratings feature EU Stage IIIa non-road certification. The QSB7 utilizes advanced combustion technology to reduce emissions in-cylinder without the need for aftertreatment. The QSB7-DM has been certified by globally-recognized marine classification societies, including American Bureau of Shipping (ABS), Bureau Veritas (BV), Det Norske Veritas (DNV), Germanischer Lloyd (GL) and Lloyd’s Register (LR). It was designed to meet Safety of Life at Sea (SOLAS) and multi-engine Unmanned Machinery Space (UMS) requirements. Built at Darlington Engine Plant in Darlington, U.K., the QSB7-DM is scheduled to begin production in mid-2012.
The engine’s high-pressure common rail electronically-controlled fuel system provides constant high injection pressure regardless of engine speed or load condition, reducing noise and vibration for quiet operation and faster load acceptance. Single loop, low temperature aftercooling eliminates the need for two keel coolers and lowers emissions. Operators have the choice heat exchanged, keel cooled, and fan drive for radiator cooled applications. The cast water cooled exhaust manifold lowers surface temperatures to levels required by SOLAS, while also improving performance, and the engine’s rear engine-mounted water cooled turbocharger from Cummins Turbo Technologies has been optimized for marine applications.
The QSB7 auxiliary engine is easily integrated with Cummins C Command HD basic and Elite Plus class-approved panels. Based on C Command architecture originally designed for high horsepower engines, C Command HD instrument panels include a selection of monitoring and display options to help operators protect and enhance engine operations and manage operating costs by logging critical operating parameters such as engine load, duty cycle, speed and fuel consumption, while providing diagnostic and prognostic capabilities. A common point of connection in the customer interface box simplifies the link between engine electronics and vessel systems.
All Cummins products are supported by a global team of marine-certified distributors offering sales, service and application expertise. Further, the QSB7-DM is covered by a comprehensive one year warranty, valid at authorized Cummins service outlets worldwide. It is also backed by Cummins industry-leading Mobile QuickServe® program. Cummins QuickServe® offers the most sophisticated diagnostic and repair tools in the industry and the largest international parts and service network of any engine manufacturer.
Cummins will showcase the QSB7-DM at the upcoming Europort commercial marine trade show in Rotterdam, Netherlands, November 8-11, marking the first time the product will be displayed anywhere in the world. Press and visitors are invited to stop by stand number 307 in hall 1 to get a firsthand look at the new 6.7 Quantum Series marine auxiliary and discuss product features with our team of experts.
