LOUISVILLE, KY -- Cummins Inc. says it will be ready to ship its full line-up 2014-compliant heavy-duty diesel and natural gas engines a full year ahead of deadline, and they'll feature improved reliability and fuel economy.

Cummins announced at the Mid-America Trucking Show yesterday that the engines will deliver up to 2% fuel economy improvement over today's products and will use the same proven high-pressure common rail fuel systems, VGT Turbocharger and fully integrated electronics for improved combustion efficiency, performance and reliability.

Base engine improvements reduce the parasitic load on the engine through high-efficiency water, fuel and lube pump systems. Cummins engines will meet the 2014 fuel efficiency and greenhouse gas standards beginning in January 2013.

"We met the EPA 2010 standard on time, and our engines have earned their industry-leading reputation for great reliability and fuel economy. Our product development teams are delivering even better products where it counts -- to our customers -- and our engines are meeting the 2014 fuel-efficiency and GHG standards a full year early," said Rich Freeland, Cummins Vice President and President of Engine Business.

Cummins will build on the success of its EPA 2010 MidRange and Heavy-Duty products with the same capable base engines and emissions architecture for 2013. All commercial vehicle diesel engines feature the Cummins Emission Solutions EcoFit Ultra-Low Emissions exhaust aftertreatment system, integrating a Diesel Particulate Filter and Selective Catalytic Reduction. On-Board Diagnostics, proven on hundreds of thousands of engines since 2007, will be extended across the entire lineup.

In addition to the broad diesel lineup from the ISB6.7 to the ISX15, Cummins will continue to offer the Cummins Westport ISL G, the top-selling natural gas engine, and it will introduce the Cummins Westport ISX12 G into full production in 2013. Cummins Westport is a joint venture between Cummins Inc. and Westport Innovations.
