Learn the operation of the most prevalent engine retarder available. Formerly recognized as a compression release brake, the Jake brake proves vital for commercial truck drivers, enhancing braking capability and reducing brake wear.
Key Information
- A Jake brake enhances braking efficiency by converting your truck's engine into an air compressor, exerting pressure on the pistons to decelerate.
- Utilize your Jake brake to manage your vehicle on descents, alleviate strain on your service brakes, and enhance fuel efficiency.
- Due to their considerable noise, Jake brakes are often prohibited for use in residential and urban areas.
Procedure
The Function of a Jake Brake
A Jake brake aids in decelerating your vehicle without engaging the conventional brakes. Trucks, being notably heavy, impose significant strain on brake pads, necessitating frequent replacement. Jake brakes alleviate this burden by altering engine configuration, allowing controlled deceleration without brake pedal input.
- Jake brakes not only preserve service brakes but also enhance stopping power when used in tandem.
- However, they cannot independently stop the vehicle and are not a substitute for functional service brakes.
- Installed directly on diesel engines, Jake brakes are activated by a switch, coupled with clutch and throttle manipulation.
Mechanism of a Jake Brake
The Jake brake employs compressed air to decelerate the engine. In a gas engine's four-step process (intake, compression, combustion, exhaust), airflow sustains momentum when the brake is released. The Jake brake interrupts this airflow, causing compressed air buildup, artificially slowing down the cylinders and facilitating deceleration.
