NEW ORLEANS (May 21, 2013) – Cummins Inc. (NYSE: CMI) announced today its 2013 engine lineup for refuse vehicles at WasteExpo in New Orleans. Cummins is offering customers a complete range of both clean diesel and natural gas engines designed for optimal performance in refuse applications. Cummins will have the ISX12 clean diesel engine in addition to the Cummins Westport ISL G and ISX12 G natural gas engines on display at WasteExpo from May 21 through 23.

Cummins is building on the success of its current Heavy Duty and MidRange clean diesel products with improvements made to all existing base engines for 2013, including up to 2 percent better fuel economy, compared with the 2012 model year engines. For 2013, Cummins will offer the refuse vehicle market two choices in clean diesel power – the ISX12 and ISL9.

Continuous product improvements to Cummins fully integrated components such as the XPI fuel system, VGT™ Turbocharger and Cummins Aftertreatment System with Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) deliver improved reliability, durability and fuel economy for 2013. All engines will share a new single Electronic Control Module (ECM) that will manage both the engine and the Cummins Aftertreatment System, for improved overall combustion efficiency. In addition, these engines meet the 2013 U.S. Environmental Protection Agency (EPA) regulations as well as the 2014 EPA greenhouse gas (GHG) and U.S. Department of Transportation (DOT) fuel efficiency standards.

“Cummins is committed to providing refuse customers a complete lineup of clean diesel and natural gas engines that will deliver better fuel economy, reliability and durability, with lower operating costs,” stated Jeff Jones, Cummins Vice President – North American Engine Business. “Cummins and Cummins Westport remain focused on continually improving our proven technology to provide products that best meet the unique needs of our customers.”

The 2013 ISX12, with ratings from 320 hp to 385 hp (239-287 kW), will deliver exceptional performance, with strong pulling power and throttle response. Modifications to the VGT Turbocharger, along with optimized calibrations, help deliver better reliability on the ISX12. Also, the ISX12 features high-efficiency water, fuel and lube pumps to help reduce parasitic loss and improve fuel economy up to 2 percent when compared with the 2012 model year engine. The ISX12 also provides customers with the options of Front- and Rear Engine Power Take-Off (FEPTO and REPTO), to best suit the needs of their specific applications.

The 2013 ISL9, with ratings from 260 hp to 380 hp (194-283 kW), will continue to deliver the same proven dependability and reliability that refuse vehicle customers have come to expect. Heavy duty features such as replaceable wet liners, roller followers, by-pass oil filtration and targeted piston cooling on the ISL9 make it an ideal choice for the demanding duty cycle. The addition of an air intake throttle for 2013 enhances the overall efficiency of the Exhaust Gas Recirculation (EGR) system, leading to improved fuel economy of up to 2 percent when compared with the 2012 model year engine. In addition, the ISL9 will now feature NanoNet™ media in the fuel filter, which provides up to 10 times better protection for fuel injectors.

Cummins Westport natural gas engines – the ISL G and ISX12 G – utilize the same base engine and key components as their diesel counterparts. They also feature Cummins Westport’s proprietary spark-ignited combustion technology with Stoichiometric cooled Exhaust Gas Recirculation (SEGR) and a maintenance-free Three-Way Catalyst (TWC).

The ISL G is available with ratings from 250 hp to 320 hp (186-239 kW), and shares a full-skirted block with Cummins ISL9 diesel engine, for greater reliability and superior durability. Cummins Westport’s ISX12 G is based on Cummins ISX12 diesel, and offers ratings from 320 hp to 350 hp (239-261 kW) with up to 1450 lb-ft torque (1966 N•m). Options such as engine braking and a choice of automatic or manual transmission make the ISX12 G an ideal heavy duty natural gas engine. Limited production began in April, with full production starting in August.

Both the ISX12 G and ISL G are EPA 2013 certified, and also meet the 2014 GHG and fuel efficiency standards. In addition, the ISX12 G and ISL G can operate on compressed natural gas (CNG), liquefied natural gas (LNG) or renewable natural gas (RNG), making them the natural choice for refuse natural gas vehicles.
