New On-Highway Diesel Engine ISX12
Cummins ISX12 builds on the legacy of the ISM and proven technology of the ISX15 to deliver better fuel economy, performance, reliability and durability. It has more horsepower and more torque, plus stronger acceleration – all in a compact design. It achieves near-zero emissions and reduces noise output. So no matter what kind of equipment you run it in, the ISX12 has the power to accomplish every task better. From morning to night.
Optimized calibrations have resulted in significant fuel economy gains for the ISX12. Fuel economy has improved up to 5% in regional haul applications and up to 12% in vocational applications versus the ISX11.9.
The ISX12 is an exceptional choice for vocational applications, with a high power-to-weight ratio and 800 lb-ft (1085 N•m) of clutch engagement torque. Eight vocational and five refuse ratings are available, along with integrated Rear Engine Power Take-Off (REPTO), Front Engine Power Take-Off (FEPTO) and a choice of hydraulic drive options. This combination of power and flexibility is an ideal choice for rear- and front-pouring mixers as well as dump trucks and refuse haulers.
The ISX12 has the power range to meet the needs of regional hauling and LTL distribution operations. Standard ratings range from 310 hp to 425 hp (231-317 kW). SmartTorque ratings unleash higher torque in the two top gears so that drivers can climb steep hills with fewer downshifts.
Cummins is the only engine manufacturer to design and develop, manufacture and support every component from the air intake to the exhaust aftertreatment in a totally integrated system.
The XPI fuel system is capable of the highest injection pressures in the industry, with a common-rail design that delivers strong performance independent of engine speed. The integrated system of the ISX12 also includes a VGT™ Turbocharger custom-built by Cummins Turbo Technologies.
The Cummins Aftertreatment System on the ISX12 combines a proprietary Cummins Particulate Filter with our Selective Catalytic Reduction (SCR) technology, functioning as a single unit. Designing and building the package in-house allows Cummins to calibrate the engine for optimum performance and near-zero emissions. The high efficiency of the aftertreatment frees the engine to generate higher horsepower while also saving fuel. Improved fuel economy not only lowers fuel consumption – it also reduces greenhouse gas (GHG) emissions.
And that’s just the start of all the features the ISX12 has to offer. Every element has been designed and manufactured to optimize performance and minimize maintenance for superior driveability.
All backed by the best customer support in the business.
