ISX15 For EPA 2010. 

Cummins ISX15 EPA 2010 delivers superior driving 

performance while improving industry-leading fuel economy. 

Plus, it achieves near-zero emissions levels without sacrificing 

the reliability or durability that you expect from a Cummins 

engine. 

Every major component and system is designed and built by 

Cummins for total quality control, building on a proven engine 

with fully integrated electronics. An improved, more precise 

air-handling system has reduced restriction, which helps 

optimize performance. 

The result is that Class 8 truck owners will achieve up 

to 5% more miles per gallon with the ISX15. In addition, 

maintenance intervals are unchanged from previous years. 

So the ISX15 will deliver the lowest operating costs of any 

engine in its class. 

For superior fuel economy, strong performance, long-range 

durability and exceptional dependability, you’ve got every 

reason to spec an ISX15. 

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. 

Single Overhead Cam – Our improved XPI fuel system 

eliminates the need for a second camshaft. This provides 

weight savings and simplifies operation. 

Cooled EGR – This next-generation system lowers combustion 

temperatures for reduced emissions and optimized fuel economy. 

Fully Integrated Electronic Controls – A single highercapacity 

Electronic Control Module (ECM) controls everything 

from air intake to exhaust aftertreatment for peak performance 

and near-zero emissions. 

Intebrake – Even with one overhead cam, the ISX15 still has 

best-in-class braking horsepower (up to 600 bhp) for greater 

vehicle control with reduced service brake wear. 

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.

Every element of the Cummins ISX has been 

designed and manufactured to optimize reliability and 

fuel economy, lowering the cost of your oil and gas 

operation while maintaining superior performance. 

The ISX features the proven cooled-EGR subsystem 

and VG Turbo. A Cummins Particulate Filter and a 

coalescing filter complete the totally integrated 

system. 

The ISX is designed for years of dependable service. 

Its turbocharger is a good example. With only one 

moving part in the hot exhaust stream, it is more 

reliable and durable than competitive turbos. Put that 

together with patented mid-stop cylinder liners, heavyduty 

components and Six Sigma design practices, and 

you’ve got an engine for oil and gas applications that 

can be depended on for years to come.

Emissions. 

Every Answer For Increasingly 

Stringent Emissions Regulations. 

The ISX allows your oil and gas operation comply with 

varying emissions standards found in different locations 

around the world. In certain regions of the United States, 

the local emissions standards require workover rig 

engines to follow more stringent automotive emissions 

levels – instead of the less stringent industrial levels. The 

one solution to these different requirements is the 

Cummins ISX, providing power not only to operate the 

workover rig equipment, but also to power the rig down the 

road, meeting every EPA 2007 automotive emissions 

standard along the way. 

Features and Benefits. 

The Cummins ISX delivers the best fuel economy of any 

heavy-duty diesel engine in its class. It also continues to 

lead the industry in reliability and durability. Advanced 

features and benefits include: 

■ Cummins Particulate Filter – Fully integrated to deliver 

uncompromising performance and reliability. Cummins 

design allows regeneration even in adverse operating 

conditions and reduces particulate matter more than 

90%. 

■ Dual Overhead Camshafts – One camshaft drives highpressure 

fuel injection for clean responsive power. The 

second camshaft operates the intake and exhaust 

valves, with dedicated lobes for the integrated engine 

brake. 

■ Cummins Intebrake – Provides greater vehicle control 

and reduced service brake wear. Up to 600 braking 

horsepower. 

■ Fully Integrated Electronic Controls – A single ECM 

(Electronic Control Module) controls the engine and 

aftertreatment. Also coordinates interaction with the 

transmission, ABS, engine brake, cooling fan and more. 

■ High-Pressure Fuel Injection System – For cleaner, 

more complete combustion. 

■ Variable Geometry Turbocharger – Enhanced 

response and control with electric actuation for infinite 

adjustment, providing exact boost at any rpm. A 

sliding-nozzle design sets the industry standard for 

reliability and durability. 

■ Cooled Exhaust Gas Recirculation – Lowers 

combustion temperatures for reduced emissions and 

optimized mpg. 

■ Crankcase Ventilation System – Electronically 

managed for optimum efficiency without adding 

parasitic load or complexity to the engine. The 

coalescing filter is easily serviced, only needing 

replacement once a year or every 125,000 miles 

(200,000 km). 

■ SmartTorque Ratings – Deliver up to 200 lb-ft of extra 

torque in the top two gears for better fuel economy, 

fewer shifts and less driver fatigue. 

■ Optional Water-in-Fuel Sensor – Alerts the driver to 

contamination that could cause performance and 

durability problems.
