ISX12 for Fire & Emergency (EPA 2010)

Overview

ISX12 for Fire & Emergency (EPA 2010)
Responding Faster. Every Call. ISX12.

Superior response is now available in the industry's most compact 10- to 13-liter engine. 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. The ISX12 is built to respond faster to every call.

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. This allows us to optimize critical systems to deliver the right technology to our customers in a way that other engine manufacturers using outside suppliers simply can’t match.

At Cummins, we know that every second is critical when you're responding to an emergency. There's no room for doubt about the readiness of your equipment - or its ability to get you to the scene in a hurry.

Being able to meet budgets is critical as well - and that's where the ISX12 with its long service intervals and excellent fuel economy can come to the aid of your operating budget.  In fact, the ISX12 delivers up to 5% better fuel economy versus the ISX11.9.

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. These technologies have been proven in the U.S. and Europe for years and thoroughly field tested under the most extreme conditions. Designing and building the package in-house allows Cummins to calibrate the engine for optimum performance and near-zero emissions. The Cummins Particulate Filter reduces Particulate Matter (PM) by 90%. 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.

Features

XPI Fuel System – The proven technology of the XPI common-rail fuel system delivers a precise quantity of fuel at ultra-high pressures. This, together with more robust electronic engine controls, enables multiple injection events per cycle. Flexibility in injection timing increases fuel economy and performance while decreasing exhaust emissions.

VGT™ Turbocharger – The Cummins VGT Turbocharger is both simple and precise. Electric actuation allows infinite adjustment, providing the exact amount of boost necessary for superior response. The proven slidingnozzle design has best-in-class reliability and durability.

Cooled EGR – This next-generation system lowers combustion temperatures for reduced emissions and optimized fuel economy.

Fully Integrated Electronic Controls – A single higher-capacity Electronic Control Module (ECM) controls everything from air intake to exhaust aftertreatment for peak performance and near zero emissions.

Cummins Aftertreatment System – The proven Cummins Particulate Filter reduces particulate matter by over 90%. In 2010 it is combined with Cummins Selective Catalytic Reduction (SCR) to meet emissions standards while maintaining best-in-class performance, reliability and durability. Cummins SCR technology has been proven in over 200,000 European vehicles and uses Diesel Exhaust Fluid (DEF) to achieve NOx emissions at near-zero levels. DEF will be readily available; reference Cummins Filtration flyer LT15618 for more information.
