Difference Between Jake Brake and Exhaust Brake

There are many different vehicles in use today. Because of their different forms and types, their working methods are also changing. In any case, there are utilized gas and diesel vehicles, and they are supplied with two types of brakes. Both of these brakes serve the same job of providing brakes to the vehicle, but they each have their own technique for doing so.

Jake Brake vs Exhaust Brake

The main difference between Jake Brake and Exhaust Brake is that the exhaust brake works by increasing the pressure applied to the brake, while the Jack brake works by releasing the pressure applied to the brake. Jake’s brake generates braking force by releasing pressurized gas inside the cylinders, whereas They cause greater pressure in the exhaust pipe by restricting the exhaust stream.

Jake Brake and Exhaust Brake

Jack brakes are commonly used on large diesel engines on tractor-trailers to help reduce car speed without damaging the service brakes. They generate a lot of unnecessary noise, which limits their use in certain areas. They work by lowering the vehicle’s pressure and causing it to slow down.

Exhaust brakes are the chosen brakes in vehicles that are both efficient and robust. By increasing internal pressure and restricting exhaust flow, they slow down the car. They are silent and undetectable brakes that work no matter what the vehicle’s size and weight. They are cheaper and can prevent standard brakes from failing.

NoiseJake’s brakes make too much noise and are therefore prohibited. When compared to Jake Brakes, Exhaust Brakes make less sound.
Power Jake brakes have well exceeded the vehicle’s rated stopping power, reaching 90 percent. Exhaust brakes have a lower braking force and can only do 60-80% of the job.

What is Jake Brake?

Jake Brakes are a form of pressure releasing brake that is commonly seen in large vehicles such as tractor trailer and huge diesel engines. Jake brakes, also known as decompression brakes or engine brakes, works by lowering the vehicle’s suction to slow it down.

The vehicle comes to a halt when the pressurised gas is released into the tank, and this function is only available in huge trucks. They are often banned due to excessive noise. Jake brakes have a number of drawbacks, including the fact that they are forbidden in some regions due to their noise. They only influence the driving tyres, thus they should be ignored on slick surfaces where they could slip or jack knifing.

The Jack Brake is a pressure release brake that helps the truck driver to slow down the vehicle while wearing the service brake. Jack brakes, sometimes called engine brakes, are often used in tractor trailers equipped with large diesel engines. When utilized appropriately, Jake Brakes can extend the life of your brakes and tyres when traveling downward or on motorway off-ramps. However, because they produce a lot of noise, some places don’t allow them to be used.

What is Exhaust Brake?

Exhaust brakes are brakes, which are used in diesel cars to slow them down despite their heavy mass. They are quite competent, and their kind and calm temperament makes them preferable. They are quieter and can be used matter the size or weight. Exhaust braking will quickly slow down mild diesel vehicles. On downward levels, they help keep the brakes from overheating, which can cause brake fading and even failure. ­

In a diesel engine, exhaust brakes reduce power in a different way than engine brakes. Engine brakes discharge pressurized gas through an exhaust valve, whereas exhaust brakes keep the pressure in the engine and decrease the spinning of the engine, lowering the speed of the vehicle. An exhaust brake is usually installed on the turbocharger’s outlet side and slows the engine’s capacity to push out or exhaust pressure.

The exhaust brake’s flap valve remains open until it is triggered. The exhaust flow is then closed and restricted by keeping it in the cylinder. Exhaust brakes are frequently activated by applying more pressure. They apply brakes by obstructing the exhaust stream, preventing the gas from exiting the pipe. As a result of the increased overpressure in the manifold, the engine gradually slows down the vehicle. Exhaust brakes typically aid in the prevention of regular brake excessive wear.

Main Differences Between Jake Brake and Exhaust Brake

  1. Jake’s brake works by releasing compressed gas from within the cylinders, which prevents downward cylinder activity. By impeding the exhaust’s passage, they enhance the pressure in the exhaust pipe.
  2. Jake’s brakes are more strong. The brakes on the exhaust are less strong than the brakes on the jake.
  3. Jake’s brakes aren’t allowed since they generate too much noise. Exhaust Brakes make a quieter sound than Jake Brakes.
  4. Jake’s brakes have far outperformed the vehicle’s rated stopping power, with a 90 percent success rate whereas Exhaust brakes have a reduced braking force and are only capable of doing 60-80% of the work.
  5. The valves train is connected to Jake’s brakes whereas The exhaust engine is connected to the exhaust brakes.

Conclusion

There is no doubt that both brakes are productive and practical, but Jake Brake has undoubtedly won. Jake’s brakes are much more important and effective, but they are still stronger. Because of their harshness, they are not the first choice. Because the loudness can cause damage to snowy areas in the winter, they are not used at that time. Even while both can cause heating, Jake’s brakes can cause some major thermal damage that Exhaust brakes aren’t meant to produce.

Although the braking force of the Jake brake is higher, the exhaust brake was chosen because of its soft and quiet characteristics. They are less likely to suffer damage. Exhaust brakes, on the other hand, have limits, such as the fact that they cannot be installed in every gasoline engine. The engines should also be large enough even with correct installation and stronger elements before they are installed.
