"Long Periods of Idling is Acceptable" says Dodge Engineer

[HBarlow]

The truck I saw in Winston was a chassis cab. That is the 305 HP engine and was labeled for the long idle. Maybe they have made a few minor tuning changes.

According to the Dodge engineer I spoke with last week no recent changes have been made. All 6. 7s in cab and chassis trucks are the same. I think the new labels you saw and the paragraph on the Dodge website are a response to new emissions laws or new enforcement action rather than a change in tuning or emissions.

There has been quite a few software updates on th C/C

Cumminz,

I wasn't disagreeing with you or doubting you saw the new decals. The point I meant to make was I don't think the new "okay to idle" decals result from a change to the engines or emissions equipment but simply from the manufacturers responding to new emissions regulations or enforcement.

Apparently manufacturers of all HDTs and MDTs are now attaching similar labels to their trucks to protect drivers from environmental wackos with ticket books in hand.

None have been made on '08 Cab and Chassis as of my visit to my dealer a month ago.

We have a few 6. 7's in various equipment at work. Some of this equipment spends 75% of it's life sitting at low idle, which for us can be 8-10 hours a day 6-8 months a year depending on how much wire we pull. I must add that all the DPFs have been eliminated. We haven't had a bit of trouble from any of the 6. 7's.

I just heard (saw a document)today that the ecms are programmed to shut the engine down after 60 minutes of inactivity,That would be idling in park or nuetral with out the hi idle engaged. It looks like the engineer you talked to is not so well versed. I don't own a 6. 7 so I can't verify thay but other techs have.

Is this in all 6. 7's? I idled two of ours today in park for 10 hours and neither one shut off.

 

[Coalsmoke]

I dunno about that, lots of guys are idling them day long and i've never heard of it shutting down.

 

[Bob4x4]

It has been an issue in the states and that is a response from engineering. I have not verified it myself.

 

[Coalsmoke]

Bob, maybe its new software in the works that will be coming with the next flash? Just a thought.

Can you provide a cut and paste copy? Or a link to it?

Dodge's own commercial website says it is okay. A Dodge engineer told me it is okay. Many owners/drivers are idling them for long periods and have not experienced such a feature.

Sorry It is from a secure website,password/user/etc. An engineering answer to an issue where a 6. 7 would stall at the 60 minute mark everytime it was left idling. It would then restart and run fine for another 60 min. I beleive it was a p-up not c/c.

 

[HBarlow]

Could be. The '07 emissions equipment on the C&C may tolerate long idle periods better than the 2010 compliant gear on the pickups and in normal circumstances a pickup would be less likely to idle on a jobsite for hours like some commercial C&Cs might so maybe Dodge/Cummins programs the ECM on a pickup to shut down after an hour.
