Every Advantage.Cummins ISB EPA ’07 does more than just meet

EPA regulations. With increased displacement,

enhanced electronic engine controls and an

increased number of injection events per combustion

cycle, it runs stronger – yet just as quiet as ever.

Plus, the ISB continues to lead its class with the

lowest total cost of ownership.

Everything from the High Pressure Common Rail fuel

injection system, proven cooled-EGR subsystem

and patented VG Turbo to the Cummins Particulate

Filter and crankcase ventilation system has been

engineered and manufactured in-house to operate

as a totally integrated system with optimized

performance. Designed and built using Six Sigma

processes, the ISB is an engine that delivers

everything you need. Every time.

Even the new exhaust aftertreatment is designed for

year after year of dependable, durable service. It has

been designed and manufactured to last for the life

of your ISB engine.

FOR MEDIUM-DUTY TRUCKS.

■ Crankcase Ventilation System – Electronically

managed for optimum efficiency. Does not add

parasitic load or complexity to the engine. Coalescing

filter is easily serviced, only needing replacement

every 2 years, 2,500 hours or 60,000 miles

(96,000 km).

■ Enhanced High Pressure Common Rail Fuel

System – Delivers optimum balance of performance,

emissions control and fuel economy across the

entire operating range.

■ 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. Plus, the ISB has every diagnostic,

maintenance monitoring and engine protection

feature that you need.

Dependability. Every Day And Every Year.Cummins ISB is designed for years of dependable

service. The proven B Series block has been designed

for even greater structural capability. Targeted piston-

cooling nozzles lower piston temperatures for increased

durability in lower ratings, while gallery cooling achieves

the same goal in higher horsepower ratings. Plus,

it features a state-of-the-art oil filter for extended

component and engine life.

Features And Benefits.6.7 liters of displacement (up 13% from the previous

model) means increased power, performance and

productivity. The aftertreatment system is designed to

operate automatically, with undetectable impact on

vehicle performance.

Other ISB benefits include:

■ Low Noise Levels – Maintains industry leadership for

quietest operation for increased driver comfort and

safety.

■ Variable Geometry Turbocharger – Enhanced

response and control with electric actuation for

infinite adjustment, providing exact boost across

the operating range. Sliding-nozzle design increases

reliability, durability.

■ Cooled Exhaust Gas Recirculation – Lowers

combustion temperatures for reduced emissions and

optimized mpg.

■ Cummins Particulate Filter – Fully integrated for

uncompromising performance, reliability. Cummins

design allows regeneration even in adverse operating

conditions. Reduces particulate matter more

than 90%.

Gearing And Transmission Recommendations.With governed speeds of up to 2600 rpm, the ISB

provides a broad band for excellent performance

when matched to various mechanical and automatic

transmissions. Select the proper rear axle ratio and

transmission combination to achieve the desired

startability and road speed.

Optional Equipment.■ Water-in-fuel sensor alerts drivers of water buildup in the

fuel filter. This is a warning sign that there may be excess

water in the fuel, which could cause performance and

durability problems.

■ An innovative oil level sensor operates like an electronic

dipstick, eliminating the need for the daily check of

oil level.

■ A larger 18-quart oil pan option allows 25% longer oil

change intervals. Additional oil in the sump means that

the additive package can keep protecting your engine

components longer. That translates into an extra 5,000

miles (8,000 km) between oil and oil filter changes.

* If engine is equipped with an optional coolant filter, it will need to be replaced on the same intervals as the oil filter.

The Cummins Particulate Filter is designed to last the life of

your engine. Regeneration is fully automated and controlled

by the ECM. See Owner’s Manual for complete details.
