14 Maritime Reporter & Engineering News Cummins Marine introduced the QSK19 engine for marine propulsion and auxiliary applications. It is the first of a new line of Quantum System marine products from 19-60 liters of displacement. The entire Quantum System engine family features an in-cylinder combus- tion process, designed to meet 2007 EPA Tier 2, European Union and CCNR Phase II emissions regula- tions. The QSK19, with ratings from 373-597 kW (500-800 bhp), is designed for high-hour, demanding applica- tions such as towing, cargo and passenger transport, and fishing and ship's service power. The engine is Type Approved and meets the latest SOLAS require- ments, and will be built and marinized at Cummins Industrial Center in Seymour, Indiana. The engine features Cummins' Modular Common Rail Fuel System (MCRS), which is designed to allow multiple injection events to precisely control engine fueling. Quantum System electronics are driven by a CM 850 controller. Integrated information systems and panels help maximize engine efficiency and per- formance while providing diagnostic and prognostic data. A single connection in the customer interface box simplifies the link between the engine electronics and vessel systems. A combination of features onboard the engine is designed to enhance reliability and durability as well as increase engine life. A single piece cast iron piston, hardened cylinder liners, and premium ceramic sur- faced rings increase the life of the power cylinder. The elimination of injector load on the camshaft and over- head rocker levers reduces wear on these major com- ponents. Additionally, a robust marinization features a water cooled triple-wall exhaust manifold and tur- bocharger with a titanium compressor to ensure the engine performs in demanding marine environments. The exhaust system design provides the added benefit of improved fuel economy while eliminating potential exhaust leaks. Minimal changes to the footprint, mounts, ratings and optional equipment from the current K and KV engines aim to ensure less complexity for new installa- tions and repowers. The engine sub-system enhancements require no added service. Additionally, Cummins Marine offers many alternatives to help reduce or eliminate mainte- nance and downtime; for example, the two-stage Fleetguard fuel filtration is designed to utilize larger elements for longer filter life; the Cummins Centinel Oil Management System is designed to increase oil change intervals by up to 4000 hours; and the Eliminator filter, which replaces disposable lube fil- ters, has been scaled in size for the new QSK19 engine. Working together or individually, the Centinel and Elminator are designed to reduce the possibilities of oil contamination during oil-related service events; help- ing to balance the needs of the environment with the expectations of marine operators.
