What Are Exhaust Brakes?

So here's how Car Brakes work : the Engine Brakes are installed in heavy duty trucks & even commercial cars like buses & some semitrailers so it can assist increase speed control. Get it? Got it? Good.

If you didn't already know, braking causes friction - which then causes heat. If there is too much heat, then your Truck Brakes can overheat & then eventually fail on you. If you downshift the transmission on certain steep grades, this can help most passenger vehicles more than big rigs because of the significant weight difference.

The Engine Brakes reduce the occurrence of normal brake failure by using the engine in your car to slow the rig. It increases the effectiveness of braking, so you save money by reducing wear & tear on the tires of the break system.

The Exhaust Car Brakes help the Diesel Engine slow down by closing off the exhaust path from the engine. This causes the exhaust gases to be compressed in the exhaust manifold. It's also compressed in the cylinder of the engine. Since the exhaust is being compressed and there is no more fuel that's being applied, the engine starts to work backwards - this slows the car down. The total amount of negative torque that's being generated is typically directly proportional to the back pressure of your engine.

Because most Diesel Engines are lack of something called a throttle valve located on the intake manifold, there is no real intake vacuum when the engine isn't using the fuel. The intake vacuum is supposed to create the drag effect that's usually felt in gas when you go down the hill with the throttle closed.

Most Exhaust Brakes are produced by a lot of companies - these companies include Pacbrake and Jacobs. A lot of the Car Brakes have different designs, but they all operate the same way. There are some Exhaust Brakes that are more advanced and have something called Exhaust Pressure Modulation that is supposed to control the back pressure which in turn is supposed to improve the braking performance for a variety of engine speeds.

The Exhaust Truck Brakes are usually mounted on the outlet side of something called the "Turbocharger". It delays the engine's ability to exhaust compression. There's a butterfly valve in the Exhaust Brake that stays open until it activates. It then closes and has a restriction on exhaust flow by keeping it in the cylinder. This can typically make the piston force the compression into the Exhaust Brakes - which then absorbs the energy.

Exhaust Car & Truck Brakes don't usually make the loud noise that most Engine Car Breaks are known for - which can be a good thing because that sound does get annoying. In fact, they make no sounds .. at all. The Compression Brakes are the ones that make an excess amount of noise pollution, if you compare it to the regular Exhaust Car Brakes on your car.

The Exhaust Brakes are manufactured to be used all of the time when you drive, not just when you need to use them. If you use your Exhaust Brakes as recommended by the manufacturer or the dealership that you bought them from, they can save you money by reducing brake service costs. They even give you some sort of "added security" if you're traveling a pretty long distance or when you're pulling a rig up a steep hill - or any hill for that matter.
