Call the new engine by its proper name!

[jwilliams3]

The Name of the ISB2 is "ECHO" due to it being super quiet.

This is what Cummins has named the engine.



Using "new ISB" doesnt sound like anything exciting.

Lets promote this great product from CUMMINS!!



GO ECHO!! GO!!

 

[Rcpilotlv]

Do I here a echo around here.....

 

[Morphious]

Sounds like the name of a little foreign car.



Morph.

 

[joesoot]

Beats something like Durastroke or Ultratorque Super Dooper Power Machine.

They call it the ECHO in its European variation. In the US in our new brand of trucks they're not gonna be so quiet. The loss of noise in the ISBe engine is due to the geartrain being rear mounted on the engine for step van use, just like the B3. 3. For the RAM, the geartrain will be back in its usual front mounted position, so the only quiet sound will be what's lost due to the common rail injection system.

On the subject of ISBe noise:

Steve St. Laurent said, "a reduction of 8-10 db of noise along with a block redesign to help keep sound levels down. "

I don’t know what the current ISB noise level is but, a reduction of “8-10db” does not seem significant to me.

 

[Joseph Donnelly]

The decibel scale is exponential, so 8-10 is significant.

Cummins called the 12 valve the Eclipse in 1998, and the 24 valve the Encore.

I doubt moving the gear train would help us with noise due to proximity of the firewall. It would make working on the engine a real nightmare. I'm glad to hear this won't happen to us.

 

[jwilliams3]

Well I can say from experience that the ECHO (thats what we call it at work) is very quiet, infact we had one driven into work the other night (2500 2003 disguised as "1500").

I was standing about 50 feet from it and had a hard time discerning if it was a Diesel or not (this is on the roof at Columbus Midrange Engine Plant) and it traveling about 25 mph.

It ended up inside, in front of our auditorium.



I got the chance to sit in a 3500 03 model year dually, and rev the engine, the noise difference is night and day from the ISB.





Diesel B59,

Common Rail is not the only feature that suppresses the sound of the new ECHO.

There are many features, this is a new engine not just an improved ISB.

 

[RATTLINRAM]

OH,,,,,,,,,,WELL,,,,,,,,,,,,,,

Number 1 Reason for not buying a "New & Improved Cummins"

I would have to come up with a different license plate.

"ECHO"????... ... . Don't they make kitchen utensils

I can't remember, but from my car stereo days I believe a 3 bd reduction in sound is pretty noticable (think it is like cutting the sound level in half). So a 8-10 db reduction should make these new engines virtually silent. This is just another reason to get a 2002 truck. Heck, who knows, but maybe a 2002 truck will be a "collectable" in future years since it was "the last of a good thing".

jwilliams3,



When does the ECHO/ISBe start down the line. I would love to hear one. It might a good time for a trip to CMEP!!



I will order a '03 as soon as the HO engine and the 48RE automatics are available and looking forward to a quieter engine. I don't like "blowing the bugle" when leaving the RV parks early in the morning!!

[Dave MacArthur]

Echo is a trademarked name (the equipment company). I doubt very seriously that Cummins would be using that name. Anyone know for sure?



Dave.

 

[jwilliams3]

Bill,

From what I know, we are probably going to start full production

in the area of May/June of the Echo/ISBe.



Oh yeah some more info on the new ECHO.



5 layer Head gasket, Canister style air filter (like BHAF),

4" exhaust system, bedplate on bottom of engine for stability,

split fracture connecting rods.

And the engine block is getting into the 400lb area.

Gears are now "straight toothed". Gear teeth are longer and sharper for more surface contact with one another.

 

[Power Wagon]

Sound levels are rarely understood.



A 3db change upward is considered twice as loud. 3db down is considered half as loud. A 9db drop would be 1/8 the apparent sound level.



That is not "insigificant" at all.



Boldt's Wagon and I did some sound pressure level readings. A mere 2 db change inside the cab is very significant to the passengers. To get some idea of the magnitude of the sound change, run at WOT in direct up to 55-60 and then suddenly cut power. That is probably only a 6 db change. In my truck, a noisy 1st gen, dropping power completely at 60 mph goes from 78 DB noise to about 72-74 db. THAT is a dramatic difference in cab noise, and it's still not as significant as the noise reduction achieved in the new generation engine. Think of it as this: The difference between loud music (Not rock concert, just radio on or TV up loud) and quiet conversation in a library. That's 8 to 12db change.

 

[1tuffram]

I'm getting the impression we're going to have to straight pipe these trucks just to be able to hear if the engine is running or not

 

[kmiller]

Sound clip

Steve's web site has a sound clip of the ISB, if any one has the ability to put one here of the new cummins I would love to hear it.

 

[Royk]

The "Echo"? Why not just call it the powderpuff or something equally dainty. Just doesn't sound like something a powerful diesel engine should be called. JMHO.

LMAO!!!!!! I agree that it doesn't sound like a name for a diesel, it works for the little Toyota though.

 

[CUMAPART]

Echo??

LMAO!!!! Echo, that's the name of weedwackers and leaf blowers. Change the name that's all I have to say.

Today I was told that the ISBe for the 2003 Dodge Ram is going to be a 305 HP with a 6 speed standar trany, no detaild on the trany. Its been a year since I been to Cummins Training and no new classes have been put together for the new Eng but I remember hearing the instructor saying that the Echo was going to be a lower end Eng, smaller and less HP than the current ISB and the ISBe was the new, improve, quieter, stronger and lighter ISB replacement. Does any one know If Mercedes is going to try to replace the Cummins with one of their Engs?
