This is not true on engines built in the last 10 or so years! And if you know you are getting ready to shut down, the last couple of miles, the exit ramp, entering the parking area, and parking are more than enough time to bring the turbo down to an exceptable temperature!

And if it is a case of shutting it down for a few minutes to run inside, sign your fuel ticket, go to the bathroom, grab a drink and snack and head back out, it is a mute point again!

The extra maintenance cost you brought up in a previous post by shutting the engine down and restarting, is minimal, compared to fuel savings and idle wear and tear! Also, with the oils and bearing materials these days in the turbos, the chance of burning one down by not letting it cool down is also very unlikely!

Now if I were running an old big cam mechanical cummins, yup, darn well bet it will cool down for a bit before it is shutdown for the day!

 

Apparently Detroit Diesel agrees with you...they suggest a minimal cool down period to let the turbo spin down.

It bugs me when drivers do that...never let the truck shut down...this burns thousands of dollars in fuel each year...for no reason... :?

 

Tom, to each their own on when to idle and not to idle at night or during the day depending on the temps. You are ok at 50-60 degree weather, but I'm not. My allergies will get me in that range of temps and then I ain't no good for driving because I need that sleepy medicene Benadryl. How do you know those trucks are running 100% of the time they are shutdown?

 

Hmm, if they are shutdown, then they would not be running!

Parked = not running down the road!
Engine off = not running and wasting fuel while they are parked!

 

Mr. Ford95, I was just referring to those who I speak with, both on the internet and at the truck stop, who tell me they never shut their truck down.

Also, your situation with allergies is a bit different than normal, i would think. If you have to idle the truck to sleep, then that's what you have to do. I do NOT advocate being uncomfortable or jeopardizing your and everybody else's safety by sacrificing sleep for a few gallons of Diesel.

I was just referring to those who, out of habit, will not shut their truck down for any reason. I see people all the time, who go into the truck stop for 20 or 30 minutes, and just let the thing run. Very wasteful, IMHO...

 

All this talk about "driver comfort" must have the old-timers just :roll: about now...

I know the first truck I ever drove was an 86 Freightliner COE that would beat your ass to death on ANY road. The AC never worked but the heater always (and I mean ALWAYS) did and the "mattress" on the bunk was a 3" thick piece of foam.

The '06 9400i I'm in now is a like "5-star" hotel room in comparison...

So....toughen up and shut that truck off. :wink:

 

country, your a riot with the smartas comments back :lol: Sorry if I wasn't clear enough for you but Tom knew what I was getting at.

Gotcha Tom, I shake my head at the one's who complain how their idle % is so high, yet they refuse to turn the truck off when they shutdown for their 10 hours, barring some medical condition. They seem to not understand the problem is, go figure......

 

. . parked on either side of me and just running away. Of course, they have to run to preserve the freight and they probably don't run any more than they absolutely need to. But run and pollute they do.

There are posters here familiar with the Maine and New York anti idling statutes. What do they say about reefer idling? Was their any discussion about how much idle time was allowed to keep the eggs fresh versus time allowed to keep the Driver fresh?

 

I agree...but reefers never "idle", they are always working, or shut off....

BUT...they take no consideration of the driver into account when they make these laws. They don't seem to realize that most drivers are company drivers, who have no control whatsoever as to the anti-idling technologies available to them. If their company will not put an APU on their truck...they have no choice BUT to idle to stay cool....but that doesn't matter....they're IDLING and that's BAD.

Don't get me wrong...I don't mean to say all idling is bad...but I am saying that if there's no purpose behind it, other than to idle...it's wrong...

Down south, in 90 degree weather in hot sun...without an APU or other air conditioning device...idling is NOT optional, IMHO....

 

But idling in upstate New York when it's -5f IS optional?
