Engine Brake and the Turbo

[jhenderson]

He’s substituting happenstance for fact. It doesn’t usually work out well for those who do that. It bites you when you least expect or can afford it.

My EB on my 2019 will definitely send the butt end over momentarily. I recovered it, but just like my semi's I'm not running the EB on ice after that experience. Even worse is the aggressive downshift of an Aisin in TH mode. That, coupled with an empty trailer, makes life exciting quickly.

For all the haters, I drive the 18 with the exhaust brake on all the time.......and it’s winter in Alaska. Didn’t have a problem with the 2012, 2014 or the 2016 on ice either.

Guess I hate loosing control on snow/ice

The snow is so cold there it is not that slippery! At least that is what I found in the winter of 72 when I was in Anchorage from 3 months.

I would assume that driving in 4wd (like you would on snow covered roads) wouldn't be too bad with the EB on....even though I still wouldn't do it on the highway at higher speeds (higher speeds for slick conditions anyway).

What is snow or ice on roads?

I find that if you use the engine brake in the smart brake mode it’s not overly aggressive and controllable in the slick ice stuff.
I just wish I could change the default settings so the engine brake will stay on and not have to be turned on every time you re start the truck. The same with the tow haul and cruise control. Have the default be the last order it was being used in when it was shut down. I’d be willing to pay for that programing update!

Not that I should get involved in this BUT...

18 wheeler exhaust brake on ice....under normal icy conditions only one set of duals lock up from exhaust brake actuation...biggest danger there back in the day was STALLING the engine as a result. Then you had to restart the engine while dealing with the sudden loss of power steering and other vital functions. If you were in the right spot gearwise you could gently engage the clutch and jumpstart it while rolling. If you were too far out of sync then either a gear change or a dive for the starter button was next...but you are not coming around in the road as a result.

Power Divider locked in?? Then two duals will lock but on different axles so you still probably are not coming around...

Four way locks engaged?? Then yes, you are going to slide...and badly if hooked to a loaded trailer and you are a little slow about grabbing the dolly brake handle...

Tire Chains on one drive axle with Power divider engaged??? Stall....or broken driveline..

Pickup trucks?? Only one wheel should lock. If you happen to have an AAM axle with a WORKING limited slip (mine has never worked from Day 1) maybe you would slide around....

I learned on overloaded, underpowered tractor trailers in the woods. I've got the T-shirt...

I can see your point with the 18 wheelers and the true Jake brake. Stalling our engines with our turbo mounted engine brake that disengages when the engine gets close to 1100 rpm not gonna happen. Truth be told you are the one driving the truck it’s really your call to use engine brake in slick conditions or not. I’ve slid down the hill in Port Jefferson more than once Anti lock brakes couldn’t do a dam thing just made it worse.
That said Life is short, Drop your shorts an slide on the Ice ! And enjoy the ride.
