There aren't.. many divert kinds of Jake's.. What you have heard is many. Different exhaust on motors that are running a Jacob's engine brakes ... some just straight pipes sone dual .. some way tall and big around and some not .. a Jake brake is just a device that. Caused the exhaust vales to remain shut and this builds more engine braking
@@jamesgibson5876 You are wrong. The jake brake does not force the exhaust valves to remain shut. In fact, it actually does the opposite and opens the exhaust valves during the compression stroke, converting the engine into an air compressor.
@@jamesgibson5876 wrong if it just closes the exhaust it would just ignites more and filling the cylinder with exhaust gasses. It should open the exhaust instead so there are less ignition happens
@@paklekj4429 shut of the injectors sobit has no fuel .. keep the exhaust vales from motor opening ...now what do you have ? You have an engine that is just building compresson... it's not loading up with fuel .....it becomes a brake at that point that
A Jake Brake is a type of compression release brake that helps truck drivers slow down their truck without wearing out the service brakes. Commonly called an engine brake, Jake Brakes are often used in large diesel engines on semi-trucks.
No they're not to prevent wearing out the regular brakes, they're for when they have to go down a steep decline. Otherwise there is absofrickinglutely no reason for them to be on because the regular brakes will slow the truck down just fine without them having that stupid loud annoying unnecessary engine brake on.
Seems like that truck was coming in very fast and at least with 60 to 70,000 lb of logs The driver did an amazing job controlling the Jake brake and the actual air brakes on the truck to slow down that amount of weight in such a short distance
He's probly got no more than. 50 thou I lbs loaded on the trailer and probly called ahead so some one was recording .. other that he was proly pushing it hard on purpose .. its just down shifting .. . Come out. Of the gear you are in tap the throttle to bring the rpms back up to about 500 more total ram at that point proly around 1900 . To 2000 .. shift into the next lower gear ..let off the throttle .. the rpms drop about 500 .. and repeat.. it isn't hard to do.. just takes getting used to it ...
@@Beansswtf he doesn’t know what he’s talking about. Coming from my experience with down shifting he was probably in 15 or 17th gear depending if it’s a 13 or 18 speed then he probably skipped like 5-6 gears at a time when down shifting as long as he was at the right amount of RPMs that’s how truck drivers shift like 3 times and already go through like 10 gears. Which when I down shift I’ll be in 18th gear and I’ll air brake and jake brake at the same time once it’s at like 5-600 RPMs then I’ll shift down to 13 or 14 then go from there to like 9 or 10th and come to a slow rolling speed and then put in neutral and parking brake on. So from my person experience I think he was in the top gear and downshifted 2 times skipping 5-6 gears at a time like a boss boy
When I was little and spending summers riding with my dad, the vibration of the diesel and jakes would lull me to sleep better than anything I've eve experienced.
Used to have a neighbor that did this for his kids when he got home for weekends, had another neighbor that fired up his chainsaw the next morning... early. Fun times.
@PuddinCup1 my school that I went to is also along us 50 but it’s not in a no jake brake zone, so when we were outside or we had the classroom window open, we could hear them. There also used to be a railroad across from the same school, but that’s long gone. The teachers said that it was beautiful hearing the train horns and jake brakes outside. Well, some of them. Other teachers thought it was really annoying.
As a wild guess, (okay, I looked at the sign) I'd say the Rayonier Wood Fiber facility, on Main Street, just south of Collins, Georgia. www.google.co.nz/maps/@32.1322394,-82.1205953,3a,40.5y,6.78h,85t/data=!3m6!1e1!3m4!1sx6ODvXKlaXCOcv05XPDsOw!2e0!7i16384!8i8192?dcr=0
Kenworths always have the loudest jakes. I remember seeing log trucks rolling down a steep grade a few years ago. Could hear the suckers from across the valley.
I always knew when my dad was coming home could hear the Jake rumbling through the valley I would wait to see him an the truck !!! Good ol days .. that was a badass Jake their
I drive an old Mac roll off up and down i-95 in New York and Connecticut. I admit I've always loved the sound of a Jake , they're very helpful in traffic. Saves a lot of wear on the brakes especially when you're loaded not to mention help to minimize your shifts. A 10-speed in traffic can get tiresome.
I drive a roll off, my Max GVW is about 73. The other day I picked up a 20-yarder filled with compacted dirt and stones. It was the only time I've had to use Low Low from a standstill. I scaled in at 93.5 my Jake got a lot of work on that load. 😂😂😟
Yes and I really liked the ones who drove around the truck stop with the jakes on thinking it was cool when I was trying to sleep cause I had to get up and deliver at 2 am
That’s what the jakes are for. To slow down without wearing out the brakes. He maybe been going a little too fast, but he made the point. As opposed to today. They want you to wear out the brakes because they’re all automatics. So you can’t control the truck.
There's a couple log trucks in my small town in Maine that do this every afternoon. You can feel the concussive force in the ground if you are sensitive to it!
