What is a Jake Brake on a semi?

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.

When do you deactivate the jake brake on a car?

The engine brake is activated when you move your foot off the throttle and deactivated when you apply pressure to the throttle. A pressure-sensing switch (or the electronic engine controls) will deactivate the Jake Brake when the engine speed falls below approximately 1000 rpm, or when the vehicle slows down to a pre-set speed.

Where does the term ” Jake brake ” come from?

Where Does the Term “Jake Brake” Come From? The name comes from the first iteration of the compression release engine brake, which was developed by Jacobs Vehicle Systems.
