Cummins Inc. announced its 2013 engine lineup for refuse vehicles at WasteExpo in New Orleans Tuesday.

Cummins is offering a range of both clean diesel and natural gas engines.

“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,” Jeff Jones, Cummins Vice President – North American Engine Business, says. 

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.

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.

The 2013 ISX12 has a rating from 320 hp up to 385 hp. 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).

The 2013 ISL9 is rated from 260 hp to 380 hp, and includes heavy duty features such as replaceable wet liners, roller followers, by-pass oil filtration and targeted piston cooling. 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(TM) media in the fuel filter, which Cummins says 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, and shares a full-skirted block with Cummins ISL9 diesel engine. Cummins Westport’s ISX12 G is based on Cummins ISX12 diesel, and offers ratings from 320 hp to 350 hp with up to 1450 lb-ft torque, and includes options such as engine braking and a choice of automatic or manual transmission.

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.
