Which name is used for the engine braking mechanism usually installed on a diesel engine?

• A. Jake Brake
• B. Jacobs Engine Brake
• C. Telma Brake Retarder
• D. ABS Interface

Answer: (A)

Engine braking on diesel engines is most commonly called the Jake Brake. This nickname comes from Jacobs Vehicle Systems, the company that developed the device, and drivers often use it to refer to the Jacobs Engine Brake—the formal product name. The Jake Brake works by altering exhaust valve operation when the throttle is closed, releasing compressed air and creating backpressure that slows the engine and the vehicle without using the wheel brakes as much. The Telma Brake Retarder is a different driveline braking method, not the engine brake, and the ABS Interface is part of anti-lock braking control, not a engine braking device. So the term drivers most typically use for this mechanism is Jake Brake.
