NEW ORLEANS, La. — Cummins today announced availability of a full line of diesel and natural gas engines for the refuse truck industry.

The company says its diesel engines will offer up to 2% better fuel economy than previous versions.

As diesel engines go, Cummins will offer the ISX12 and ISL9 to refuse truck customers. All engines will share a common electronic control unit (ECU), which will manage both the engine and the aftertreatment system, for improved overall combustion efficiency, the company announced at Waste Expo.

The engines meet the 2013 EPA emissions standards as well as 2014 greenhouse gas regulations.

On the natural gas side, Cummins Westport will offer the ISL G and ISX12 G engines, utilizing the same base engine and key components as their diesel counterparts.

The ISL G will be available with ratings from 250-320 hp while the ISX12 G will be available with 320-350 hp. Customers can choose either an automatic or manual transmission with the ISX12 G. Full production of the 12-litre gas engine begins in August.

Like their diesel counterparts, the ISX12 G and ISL G are EPA13 and GHG14 compliant.

“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.”
