Engine retarders are designed to provide additional braking power by using the engine's own compression to slow down the vehicle. This functionality is particularly beneficial when driving downhill or when maintaining a controlled speed, allowing for safer handling of heavy loads without excessive wear on the brake systems.

Unlike standard brakes, which can overheat from prolonged use, engine retarders reduce the reliance on brakes, thereby extending their lifespan and improving overall vehicle safety. This feature is widely utilized in commercial vehicles, such as trucks and buses, to enhance stability and control when navigating declines or heavy traffic situations.

Understanding the role of engine retarders is crucial for effective vehicle operation, especially in commercial driving where heavy loads and long distances are common.
