A Jake brake in simple terms turns a power producing engine into a power absorbing air compressor . Good Video !

The first time I saw the term "jake brake" was when I was passing through the residential area of a Boston suburb - located between the interstate and a commercial area. The sign said, "No Jake Braking". When I looked it up, I realized I'd been hearing semis engine braking all along - used it myself on my car when I drove a manual shift - but I didn't know the term. :D

in a pneumatic braking system, the air pressure releases the brakes, when you lose pressure, the brakes lock for safety.

Never use engine brakes in icy conditions

I had to watch a video about this because I didnt know what the truck drivers at work were talking about but I didnt want to look stupid. they were talking about engine breaking, but their truck are modern automatic trucks. When i engine break on my bike, I just sit there and release the clutch in gear and dont give it gas and it slows down, that's what I thought they meant. this is totally different

[paulholmes]

Sir, You talked about what these systems are called, and they exist but you did not get into either the engine brake systems, i.e. valve timing in relation to piston cycle positions OR the fundamental differences of hydraulic and air brakes. For instance, air brakes are easily disconnected and reconnected among other things.

Can you please make a research about each engine brake style of each brand? They are all different and would like this channel to break it down for us, Volvo for me has the best of all the engine brakes!

Your wrong about the noise. The nouse is the coolest part about them

[jasonstclair]

In a car there is normally a throttle (carburetor, throttle body, or on some cars variable valve opening) that restricts the amount of air that enters the engine which creates a vacuum that the engine is working against and helps slow the vehicle. A diesel engine on the other hand does not have a throttle and has no means of slowing the engine internally which is where engine brakes originated from. The engine brake is way more effective than a throttle would be. Some engines also use the turbo to create higher exhaust pressures to help with slowing down the vehicle also before the standard engine brake kicks in.

Air brake systems works against a power reservoir. So, if your air goes away the brakes automatically lock and the vehicle stops/cannot start to move.

About brakes, there are a lot of disk brakes on a new semi trucks. They are more effective. Don't use engine brake on sharp curves and black ice road. Make sure truck is straight it most effective and safe time to use a engine brakes.

[williamwarner]

The info was as accurate as the animations. 😂

[angela_eric]

I've always wondered what engine brakes were. As a normal driver, I would see signs at the start of small towns about not using engine brakes in town. I didn't understand why those signs were necessary. Thanks for the info.

[hermanjohnson]

Interesting. The concept that this is implemented much differently than in a manual passenger car.

[michaelsheets]

Never ever use an engine or exhaust brake on slick or icy roads. You will have one wheel doing up to 90% of the braking you're asking for trouble. Distributing the braking over 10 wheels helps the truck slow safely.

[Werry_Rang]

How would engine brakes increase emission when they do not require any fuel?

[russvoight]

Jake Brake is a trademark of the Jacob's Manufacturing Co.

[alanmay]

european trucks have a thing called Retarder which are mainly made by VOITH you should make a video about that! its connected to the gearbox.

[redmarcus]

When driving in slippery conditions, dont use the engine brake. Unless you want to be like El drifto.

[bloqk]

I wonder what the technology will be to emulate "Jake Braking" for the upcoming arrival of EV trucks?
