Parked Regeneration

This is our first truck with dpfsystem and heard if you need to do parked regeneration not to do it on asphalt just wanted to know if anyone has done one on asphalt what do you do if someone has no choice

First I've heard of it. I've had to do it a couple times in our casscadias. Pretty sure those times were on asphalt to. Didn't really seem to have any effect on anything.

So in other words I have no idea how to answer your question. Sorry

The reason for doing it on asphalt is the potential fire hazard if you perform it over a grass area. The exhaust gets extremely hot, at night you can see the canister start to glow.

It is very important that you be careful where you perform the parked regeneration. As Robert said, the exhaust is lava-hot! Don't do it in a grassy area, don't be parked next to another truck and make sure there's no trash on the ground under your truck.

Definitely don't underestimate the dangers of the parked regeneration.

Most importantly, don't do it under trees, overhanging roof, anything else over the stack, or below if you have the horizontal exhaust.

Something else about parked regen. You'll have to be sitting for quite a while idling for the light to click on the dash letting you know it's due. When you're driving, it occurs without you really knowing it. Generally the only time I've noticed it cleaning the DPF while driving is if it's during a cycle and get off the highway. When I come to a stop, the exhaust temp will light up but once you start moving, it kicks back off.

While running up to the Williston Oil fields last year last year, I found out it would only have to do a regen (2014 Cascadia) when I parked for the night. I usually wouldn't high Idle all night (truck had Calif 5 min regular Idle shut off) except when it got down to -30 below as the APU couldn't keep up. The problem is if your sleeping and don't push the Regen switch when it starts flashing, then engine will shut down with a fault Code, if your lucky you can restart the engine and do a Regen, worst case you end up having to be towed to a dealer for repairs. One of our other drivers got a hotel because it was so cold, left his truck idling, came out in the morning, truck was Froze up because it faulted out and shut down, took him over a week to get back to Chicago. Regen is a PITA !

APU:

Auxiliary Power Unit

On tractor trailers, and APU is a small diesel engine that powers a heat and air conditioning unit while charging the truck's main batteries at the same time. This allows the driver to remain comfortable in the cab and have access to electric power without running the main truck engine.

Having an APU helps save money in fuel costs and saves wear and tear on the main engine, though they tend to be expensive to install and maintain. Therefore only a very small percentage of the trucks on the road today come equipped with an APU.

I'll ask. What's regen?

I'll ask. What's regen?

International engines don't use DEF (diesel exhaust fluid) part of the new clean air policies regulating big trucks big diesel engines. What they've devised is a system where sensors monitor the soot buildup in a specially designed filter. Once it reaches a certain level, it super heats the exhaust to burn off the soot making for cleaner emissions.

Sometimes, when the truck sits and idles, you have to hit a switch to manually enable the regeneration function that normally takes place while driving. If your don't do it when the computer calls for it, it can clog up and cause all sorts of problems. Some guys call it the potato in the tail pipe.

On a Funny Note, my Cascadia has the short exhaust pipe that dumps down inbetween the Drives, makes one heck of a steam cloud when it's -25 below or colder. Somewhere I heard/read of a story where a Trooper who pulled a Driver over to write him up for drive brakes burning up, Driver pointed to the Shorty exhaust pipe down between the drives, Trooper waved see ya
