We have all seen it. My dad told me when I was a kid, that if they shut the motor down, it was difficult to restart. I ask because it's on my mind, I recently moved and had a huge moving van spend two days just burning diesel for no apparent reason. What gives?
-
Illegal to do that in a lot of states...not sure about Illinois..
-
No block heater? batteries don't work very well when cold all of the above?
-
I have a one word answer to this question, stupidity. Today's computerized diesels don't need this and it can be harmful to them. It can also be blamed on rudeness, like the "rolling coal" form of abuse of your fellows.

They're probably in the sleeper taking their mandatory time off, watching TV on the dish, cooking with a microwave ran on a inverter and running the air or heat. Some drivers have trouble sleeping w/o the motor running. Some truck stops have an air duct system that connects to the rig for heat and air and have power hookups so the tractor can be shut off.
-
Drivers sleeping with desire for HVAC, a lot of these trucks have refrigerators and other appliances, and I’ve heard that some drivers need that background noise to sleep.
I’ve seen estimates of $50 per night diesel use, not to mention the environmental effects.

I'm an interstate truck driver and I assure you, getting to sleep is no problem.
The engine will idle for a period to allow the turbo to cool then will shut off automatically, if the timer is rooted then it will idle 'till it's out of gas.
I'm sure some blokes do it as an extension of their...."masculinity"... :embarrassed: :rolleyes:

Truck driver, that explains it.

Not only big trucks. In Australia we have a plague of diesel powered 4X4 dual cab utes and many times I've wondered why many drivers insist on leaving the motor idling not necessarily all day or overnight but for up to half an hour or so for no apparent reason.
-
Alberta is the home of the diesel quad cab F250, Dodge Ram etc... lift kit, $10K tire package and they leave the damn things idling in a parking lot while grocery shopping in the summer.
Its a dumb ass 'look at my big truck' mentality, goes with the white sunglasses and the ball cap worn backwards, doesn't matter the age, twenty somethings to fifty somethings racing from stop light to stoplight.
-
well bust my bubble.. I always thought there was a real reason for that..

[/quote. Around here we have diesel truck with a flat bed, bale spike and a blue healer. But they shut the truck off at a beer stop 👍

Yeah not bad...for a beginner.
But a little open ended, sort of like, whatever someone says you mean, you can say..
"Yeah exactly"
What does it "explain"...do tell.

Heat in the winter and AC in the summer, I didn't need it to sleep. I had the refrigeration unit on the trailer just behind the cab to rock me to sleep. Happens less now because of APUs being fitted to trucks. Idling that big engine burns a gallon per hour, the APU, only a gallon every 8 hours. When i was parked in a rest area in South Dakota and it was -35F, there was no way in hell I was turning that engine off.
-
I had a CDL and drove tankers for a couple of years ( do not miss it ). I've never heard of leaving a truck idling unless you were unloading it using the PTO pump. (tankers and some dump trucks).

That's easy to explain completing a DPF burn.
-
the reason that people with a ram 3500 do that is they want everyone to know they pay $8800 for that option
-
Well, growing up as I did... my initial answer is "diesels don't like -55C nights".
But, I'm guessing this doesn't realty apply to your location?
-
Temps were well above freezing. I'm thinking the driver just didn't care. I asked one of the crew and he said the driver was probably sleeping.
-
Maybe the cargo required some sort of climate control.
-
Maybe pneumatic starters with air leaks...Maybe worn engines with leaky injectors, maybe the driver doesn't care..I notice the UPS package delivery trucks,mostly Diesels around here, always shut off the engine when the driver steps out to deliver a package even if it's 10 feet away..I asked if the engine was killed automatically when he left the seat... He said, no, it's UPS policy and the onboard tracking devices that tell management he didn't shut it off, will get him a ass chewing from his manager...
-

Reefer trucks always have a separate motor for the cooling system, they operate independently of the truck itself.
-
Reefer madness!

Depends on the truck. An older truck? Cold temps? Driver will leave it idling.
Many newer Over the Road trucks come equipped with an APU (Auxiliary Power Unit), a small generator that will run the heat/air/fridge/etc in the sleeper. So, sometimes you may hear a newer truck "running", but it's the efficient APU, and not the prime mover.
As mentioned, it's becoming common for States and Locales to have anti-idling laws and ordinances. That's the reason for the rise in APUs on OTR trucks.

For UPS and FedEx, I think the policy is more about keeping the truck from being stolen than saving fuel...

Diesel technology has really improved a lot, as I learned temping at UPS over the holiday peak season. Back in the early 90s a cold front had come in from the north during the afternoon and by dark it was around zero. A whole bunch of diesel powered semi tractors had been parked for the day on the north side of the building and the first couple drivers assigned to them reported hard starting. I and a couple other drivers came on duty at 5pm and were assigned to getting every one of the cold tractors started. After a battle (throttle to the floor, crank 30 seconds then give the starter motor a break, and ignore the growing cloud of smoke) about half of them started. The mechanics came out with jumper batteries and got most of the rest started, and a couple had to towed inside to warm up.
After a decade across the street doing the same job at the Post Office I retired and again temped at UPS for a couple peak seasons from 2005 to 2007. By then all the old diesel semi tractors had been replaced with new ones with electronic fuel injection. They'd leave them parked outside all weekend and sunday evening it's be zero degrees and they'd start right up with no drama.
That's why I have a hard time understanding why anyone would want to go back to the bad old days of mechanical injected diesels...

Careful you'll get the suspender snapping I'd change a bike from injection to carburetor crowd going, It depends on the manufacturer the modern diesels are much much more sensitive to air quality and fuel contamination than the older vehicles and if the manufacturer has either done little to taking a few short cuts with their filtration they can turn anything into a unreliable POS, i.e. how Toyota flushed the reliability reputation of the Landcruiser down the S bend with a motor change.

Ha ! Take a bow TC :bow:

Besides that, if you shut the engine off, then you have to go through THIS to get it started again, at least in Australia ...

That brings back memories! Back in the mid-'90s one of my neighbors owned a construction business and his "company truck" was a Mack R series dump truck. Every morning I'd hear that same sound. :grin:
-
My Dad took me out to Southern Railroads, Norris Yard in Irondale, Alabama when I was home for Christmas holidays about 30 years ago. They had given all of the Engineers a few days off and had well over 200 locomotives sitting in the Yard, idling. Weirdest thing I ever saw regarding trains.

Ask what the cost is of replacing electronic injectors on a modern PU truck, the ones with the $8000 Diesel option...And they do fail...

When I was driving in the mid 90's, I kept it on to keep the heat/ac/TV running and it helped me fall and stay asleep. Plus, that old cab-over Pete was the most cold-blooded thing I've ever driven, and the startup/warmup sequence was a complete nightmare (especially during cold weather), so the 6 gallons of wasted fuel per night was well worth it to me. Thankfully, I don't have to "drive to live" anymore.

I've never seen one take the keys though. From what I understand, UPS has measured and tested everything from here till Sunday and they beleive this is the right way economically to do it.

My UPS guy just pulled up with a package. I asked him about the "idling" policy for UPS drivers.
He said:
(1) If you set foot on the ground, you must have your keys out of the ignition and in your hand.
(2) If the hand scanning unit is pulled out of its charging port on the dash, the ignition must be "Off". If it's not, it sends a signal to the depot and the driver has to explain why he didn't cut the engine off before leaving the driver's seat. Anything the UPS driver does requires the hand scanner. They don't make it cut off automatically in case there's some sort of emergency.
He said that in their UPS driver training, they didn't explain why the rules are like they are (fuel? safety? theft? Engine longevity?); they don't want the drivers "improving" things on their own initiative because they think they know why it's being done. "Just do it", they said.
So that's one UPS driver in Central Virginia today. Another time, another guy, another place may have a different take or different training .... ? Not mine to reason why ....

A buddy of mine with somewhat of a short fuse was getting annoyed with a guy leasing garage space from a repair shop down on the corner from him, idling his diesel truck the entire time he was there. Happened more than once, I guess. So my buddy storms over there, climbs up into the cab and shuts the thing down and throws the keys down the street. The guy was stunned that such a thing just happened, while no doubt my buddy gave him the Yosimite Sam treatment. Buddy went to jail that night for some trespassing charge.

They have the driver's actions programed to a pretty high level, they are all sorts of rules about where to pull & park, how to exit/climb back into the truck (3 points of contact), the distance they cover between the truck & the parcel placement, how to use the horn....
Supervisors/auditors do follow them anonymously and review how closely they adhere to guidelines.
It won't be long until the hand scanner (or some other wearable tech) tracks their steps, stoops, bends, reaches, and twists in order to log the movements in a system to figure out the absolute MOST EFFICIENT POSSIBLE WAY to be a UPS Driver. Amazon is already piloting such tech on their warehouse workers.
Of course that's only an intermediate step before the robots, drones, and self-driving trucks take over!
As a matter of fact, they will probably use the data gathered from the efficiency of human movement studies when designing the robots :boozing:

That'll be the end of bringing it to my doorstep. I'll have 'em drop it at the local village store to my attention before any of that stuff comes down MY road .... ! :thewife:
