Sometimes the more things change,

the more they stay the same.For decades, Caterpillar has led theindustry with engine innovations thatprovide the powerful performance,fuel economy and overall value truckowners want most.

Now our 2003 lineup of on-highwayengines, featuring the exclusive

ACERT technology, extends ourhistory of innovation and qualityinto a new era of environmentalstewardship.

A Legacy of LeadershipCat began setting the pace back in1932 with the introduction of thefirst mobile diesel engineand wehavent slowed down since. Fromour introduction of turbocharging in55 to the first dual overhead cam

engine in 67 and the worlds onlyhydraulic engine retarder in 73,weve continued to lead the waywith forward-thinking solutions thattrump the competition. A prime

example: today, air-to-air aftercooing is an industry standard in NoAmerica. But it was generallyunknown in 1985, when Cat introduced this revolutionary method cooling intake air.

Now weve taken another bold sforward. Caterpillar On-HighwayEngines for 2003 still pack the hihorsepower ratings, peak torqueadvantages and rugged durabilityCaterpillar truck engines are knofor. But theyre better than ever,thanks to the breakthrough systems solution of ACERT thcombines proven Cat componeand proprietary technology intotodays most inventive and effectemissions reduction system.

Brand New M odels,

popular 3126E, all the way throughto the heavy duty C15 (formerly the3406), these engines employ designand engineering concepts that havealready been tested and proven reli-able in real-world applications. Thisensures the uninterrupted continua-tion of the value youve come to

expect from Cat.ACERT technology represents theculmination of years of unparallelednnovation and unprecedented suc-cess where it counts most: on theroad. Because it utilizes our ownproven air, fuel, electronics andaftertreatment systems, it couldonly have come from Caterpillar.And because engines featuringACERT technology offer the per-

formance, reliability and economythat add up to leading-edge value,the Pure Power they deliver is avail-able only to Caterpillar customers.

For the third year in a row, Caterpillar O n-Highway Engines

have received the highest customer satisfaction rankingsfrom international marketing firm J.D . Power and

Associates.*

Since 2000, Caterpillar engines have been ranked

highest by J.D. Power and Associates in Customer

Satisfaction in both Over-the-Road and V ocational

Heavy D uty D iesel Engines.

This three-peat in ranking highest is one of the

industrys most prestigious awards and indicates

that not only does Cat lead the w ay w ith innovative

stewardship of the environmentCat engines continue

to set the pace for overall customer satisfaction.J.D. Power and Associates 2000-2002 Heavy Duty Truck Engine StudiesSM based on responses from principal maintainersof heavy duty trucks. Over-the-Road segment consists of over-the-road vehicles with sleepers. Vocational segment

History of Cat Innovation


4/13

When tougher emissions regula-

tions went into effect in 2002,

other engine makers turned

to a compromise: Cooled-EGR

(Exhaust Gas Recirculation)

technology that recycles exhaust

back through the engine in an

attempt to reduce emissions.

But Caterpillar engineers didnt

stop there. Instead, we continued

to search for a better answera

long term solution that would

provide the same kind of reliability,

durability, fuel economy and

resale value Cat customers have

always counted on.

After intensive lab testing and

millions of miles of real-world,

on the road proof, we discovered

the answer: ACERT technology,

an innovative systems solution

that derives from proven Cat

components and technology.

Its a revolution through evolu-

tion that not only meets todays

clean air regulations, but also

establishes the building blocks

for attaining tomorrows more

stringent standards. Most

importantly, ACERT technology

Revolution Through Evolution

provides Cat customers with all

of the reliability, durability and

fuel economy Cat engines are

renowned for providing.

ACERT technology is C aterpillars

innovative, long-term solution for

generating Pure Powerand pure

customer value. The following

pages detail how this break-

through technology combines four

existing engine systems into a

single, unparalleled success.

Minimizing exhaust emissions andmaximizing fuel economy requiresthe most complete combustion pos-sible. So Caterpillar engines withACERT technology employ time-test-ed HEUI and MEUI (Mechanicallyactivated, Electronically controlledUnit Injection) fuel systems.

Both of these systems are

designed and built by Caterpillar.This proprietary technology allowsus to fine tune each fuel systemfor each unique engineand yourapplication.

Increasing Fuel EconomyThe C7 and C9 engines feature ourproven HEUI fuel system, while theC11, C13 and C15 feature the CatMEUI fuel system. Both the HEUIand MEUI systems are designed toprovide a patented split injection

Improved air management, a basicbuilding block of ACERT technology,is also the most visible of its fourintegrated systems. Caterpillarheavy duty engines with ACERTtechnology employ series tur-bochargers to force more cool,clean air into the combustionchambernot the recycled exhaust

gas of cooled-EGR technology.And Cat engines with ACERTtechnology use proven turbotechnology, not the complicatedVariable Geometry Turbochargercomponents employed by someother engine manufacturers.

Working together in series, the

With split injection, a minute amountof fuel is injected at the beginning ofcombustion. This is the pilot injection.A millisecond later, during combus-tion, a larger volume of fuel is usedas the main injection. Then a post

injection, another smaller amount offuel, completes the cycle. Howmuch fuel is injected at each phaseis determined by advanced Catelectronics.

Cutting Emissions at the SourceThe split fuel injection strategy incor-porated into ACERT technologylowers peak cylinder temperatures,allowing fuel to burn more completely.This translates to not only lower emis-sions, but also superior fuel economy.

Controlling Air VolumeACERT technology is also able to

control the air volume required atvarious engine loads and speeds,resulting in more complete combus-tion and better fuel economy. This isaccomplished through variable valveactuation. Inside the engine, thisprocess allows precise control ofvalve actuation complementary tocamshaft actuation. Valve position

Only the Cat air managementsystem with Cat electronics makevariable valve actuation possible,because it utilizes technology fromour proprietary HEUI fuel systemand our extensive knowledge of

hydraulics.

While the combustion processfunctions to cut oxides of nitrogen(NOx), its only part of the story.Regulated exhaust emissions alsoinclude particulates, hydrocarbonsand carbon monoxide. So a simple,effective exhaust aftertreatmentcompletes the story of ACERTtechnology: the Caterpillar DieselOxidation Catalyst (DOC).

Counting on Proven ComponentsProven reliable over time, thestainless steel Cat DOC has nomoving parts, requires no mainte-nance, and is literally designed tolast as long as the engine itself. Infact, over the past decade morethan 120,000 engines have beenmanufactured utilizing this uniqueaftertreatment systemand haveshown virtually no reliability issues.

Located in the exhaust system, theDOC consists of a honeycomb-likestructure covered by a chemicalcoating that acts as a catalyst. Ashydrocarbons, carbon monoxide andparticulate exhaust emissions passthrough the DOC and come intocontact with the catalyst, they arechemically converted into carbondioxide and water vaporharmlesssubstances that are subsequentlypassed on out of the exhaust system.

Taking the Final StepSimply put, Cats proven DOCaftertreatment system represents elegant engineering at its best.Its the final step that allows engineswith ACERT technology to meettodays tough emissions standards.

Its also one more example of howyou can count on Cat to come upwith solutions that work in the realworld, systems that work togetherwell, and products that provide max-imum value for the long haul.
