Why are Jake Brakes prohibited in some areas?
Jake braking is illegal in some areas due to the noise disturbance it produces; often resembling the sound of gunshots and in some areas could potentially cause environmental repercussions.
What is the point of a Jake Brake?
The Jacobs Engine Brake® (also known as the “Jake Brake®”) is a diesel engine retarder that uses the engine to aid in slowing and controlling the vehicle. When activated, the engine brake alters the operation of the engine’s exhaust valves so that the engine works as a power-absorbing air compressor.
Why do trucks use Jake Brakes?
The Jake Brake releases compressed air from the cylinder, slowing the vehicle by absorbing the engine’s power. Jake Brakes are commonly used to control the truck speed while descending a steep grade, rather than using the foot brakes, saving wear on the brakes.
How does a Jake Brake sound?
Engine brakes often get a bad rap due to the noise that is attributed to their use. When a semi uses engine brakes you will often hear a loud blat-blat-blat, sometimes referred to as a Jake Bark because the compressed air is forced through the exhaust valve in the engine’s cylinder.
What is the difference between Jake Brake and exhaust brake?
The main difference between the two is in how they operate. A Jake brake creates braking force by releasing the compressed air inside the cylinders. In contrast, an exhaust brake blocks the path of the exhaust, causing an increased pressure in the exhaust manifold.
