What is Engine Braking and How to Use It in an Automatic Car to Avoid Mechanical Problems

Drivers of automatic cars can leverage engine braking to enhance safety and prevent mechanical issues, especially on steep descents. This technique involves using lower gear settings, often labeled as 'B' (Brake) or 'L' (Low), to control vehicle speed without solely relying on the friction brakes.

La Nación highlights that understanding these modes is crucial for efficient driving. In automatic transmissions, the engine's resistance to turning when not accelerating acts as a brake. This "freno motor" or engine brake is particularly beneficial on long downhill stretches, where continuous use of the conventional brakes can lead to overheating and potential failure. By downshifting or selecting a lower gear, the engine's revolutions per minute (RPM) increase, creating a stronger braking effect that slows the car naturally.

This method not only preserves the life of the brake pads and discs but also offers a more controlled descent. Drivers can maintain a steady speed, reducing the risk of losing control. The article suggests that familiarizing oneself with these functions can lead to a more secure and economical driving experience, minimizing wear and tear on the vehicle's primary braking system.
