Cummins Inc, one of the leading manufacturers of diesel engines for the commercial marine industry, introduces the new QSK95 engine with 4,000 hp (2,983 kW) output as the most powerful high-speed diesel configured for marine propulsion and auxiliary generator sets. The 95-litre, 16-cylinder engine is designed ready to meet US Environmental Protection Agency (EPA) Tier 4 emission regulations taking effect in 2014, Cummins says.
The QSK95 offers flexibility in power configurations for propulsion, auxiliary, genset and diesel-electric applications, and with ratings from 3,200 to 4,000 hp (2,386-2,983 kW), the QSK95 provides an ideal solution for high-hour, hardworking vessels such as tugs, inland waterway towboats, offshore support vessels, passenger transport, dredgers, short sea cargo and coastal tankers. While achieving a power output previously exclusive to medium-speed marine engines, the QSK95 brings the advantage of a lower capital cost, a more compact installation and exceptional fuel efficiency. Extended service and more cost-effective rebuilds add a further economic advantage. The QSK95 meets International Maritime Organization (IMO) Tier II and EPA Tier 3 emissions standards with highly efficient fuel injection and clean combustion. For highly emission-regulated areas around the world, the QSK95 will lead the way forward for 4,000 hp (2,983 kW) marine engines to achieve EPA Tier 4 emissions using Cummins's own exhaust after-treatment systems. This uniquely integrated solution will offer more efficient packaging and reduce space constraints. The QSK95 has been engineered for environmental stewardship, meeting Green Passport requirements for zero disposal impact. Further, the Cummins ELIMINATOR oil filtration system eliminates the need for lube oil filters, while on-engine fuel filter replacement cartridges make for more cost-effective maintenance and disposal. Customers can feel confident knowing that the teams working on QSK95 projects bring with them years of commercial marine experience.
