Cummins Westport Begins Developing New Gas Engine, Canada

Cummins Westport announced it has begun development on the ISB6.7 G, a mid-range 6.7 liter natural gas engine designed to meet the increasing demand for on-highway vehicles powered by lower cost, cleaner and increasingly abundant natural gas. As a leading supplier of natural gas engines, Cummins Westport Inc. continues to expand its product range to supply the growing demand for natural gas engines.

The ISB6.7 G engine will be based on the Cummins ISB6.7 diesel engine and will use Cummins Westport’s proven spark-ignited, stoichiometric cooled exhaust gas recirculation (SEGR) technology. Exhaust aftertreatment will be provided by a simple, maintenance-free three-way catalyst.

The engine will run on compressed natural gas (CNG), however, the natural gas may be stored on the vehicle in liquefied natural gas (LNG) state or as CNG. The ISB6.7 G is expected to be in production by 2015 and will be designed to meet Environmental Protection Agency (EPA) and California Air Resources Board (CARB) regulations in force at the time of launch.

“The addition of the ISB6.7 G will round out our family of high performance natural gas engines,” said Jim Arthurs, President of Cummins Westport. “It joins the 8.9-liter ISL G, with over 16,000 engines in service, and the 11.9-litre ISX12 G, which will start production in 2013, to give our customers a broad range of natural gas engines for on-highway applications.”

USA: Cummins Introduces New 4000 hp Diesel Marine Engine QSK95

Cummins Inc, a leading manufacturer of diesel engines for the commercial marine industry, is going to introduce the new QSK95 engine with 4000 hp (2983 kW) output as the most powerful high-speed diesel configured for marine propulsion and auxiliary generator sets.

The 95-liter, 16-cylinder engine, revealed today at the Seymour Engine Plant, is designed ready to meet EPA Tier 4 low-emissions regulations taking effect in 2014.

The QSK95 will allow Cummins to meet our customers’ growing power requirements, while meeting increasingly more stringent global emissions,” said Jenny Bush, General Manager– Cummins Commercial Marine Business. “It also strengthens Cummins position as a global player in the commercial marine industry by allowing us to enter new market segments.”

The QSK95 offers flexibility in power configurations for propulsion, auxiliary, genset and diesel electric applications, and with ratings from 3200 hp to 4000 hp (2386-2983 kW), the QSK95 provides an ideal solution for high-hour, hardworking vessels such as tugs, inland waterway towboats, offshore support vessels, passenger transport, dredges, 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 is easily integrated with Cummins C Command Elite Premium and Elite Plus class-approved panels. C Command 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.

The QSK95 meets IMO Tier II and EPA Tier 3 emissions standards with highly efficient fuel injection and clean combustion. For highly emissions-regulated areas around the world, the QSK95 will lead the way forward for 4000 hp (2983 kW) marine engines to achieve EPA Tier 4 emissions using Cummins own exhaust aftertreatment systems. This uniquely integrated solution will offer more efficient packaging and will 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.

With countless successful globally coordinated projects to our credit, the technical teams assigned to QSK95 marine projects will work closely with the customer, shipyard and naval architect to ensure long-term benefit,” said Geoff Conrad, QSK95 Account Executive – Cummins Commercial Marine Business. “We are looking forward to working with our current and prospective customers on QSK95 opportunities and projects.”
