Cummins rolls out engine line for refuse market

May 22, 2013

NEW ORLEANS. Engine-maker Cummins revealed its 2013 engine lineup for refuse vehicles at WasteExpo in New Orleans this week, showing off both diesel and natural gas-powered models.

The OEM plans to offer the diesel-fired ISX12 and ISL9 for the refuse truck market in 2013, noting that both meet the 2013 and 2014 Environmental Protection Agency (EPA) and Dept. of Transportation (DOT) greenhouse gas (GHG) fuel efficiency standards.

The 2013 ISX12, sporting ratings from 320 hp. to 385 hp., also features modifications to its variable geometry turbocharger (VGT) along with: optimized calibrations; high-efficiency water, fuel and lube pumps to help reduce parasitic losses and improve fuel economy up to 2% compared to 2012 model year engine models; plus both front- and rear power take-off (FEPTO and REPTO) options.

The 2013 ISL9, with ratings from 260 hp. to 380 hp., offers 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% when compared with the 2012 model year engine, Cummins said.  In addition, the ISL9 will now feature NanoNet media in the fuel filter, which provides up to 10 times better protection for fuel injectors, the OEM added.

In terms of natural gas power, Cummins is offering the Cummins Westport ISL G and ISX12 G to refuse fleets for the 2013 model year – engines using 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., with the ISX12 G offering ratings from 320 hp. to 350 hp. and up to 1,450 lbs.-ft. of torque. Options include engine braking and a choice of automatic or manual transmission for the ISX12 G, which went into limited production last 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).
