How to Use Engine Braking to Slow Down?
2 Answers
Methods for using engine braking to slow down: When deceleration is needed, release the accelerator pedal without pressing the clutch or shifting out of gear, or shift to a lower gear for more pronounced engine braking effect. Below is more information about engine braking: 1. Using engine braking means lifting the accelerator pedal without pressing the clutch, utilizing the compression resistance, internal friction, and intake/exhaust resistance generated by the engine's compression stroke to create a braking effect on the drive wheels. 2. Also known as "coasting in gear," it means keeping the gear engaged without applying throttle, so the engine exerts no driving force on the vehicle. 3. Since the rotation of the wheels drives the transmission system, the idling engine generates a counteracting resistance force on the vehicle. The higher the gear, the less the engine's effect on the vehicle, and vice versa.
I often use engine braking to slow down when driving on mountain roads, simply put, it's downshifting to let the engine help slow the car. For example, on steep slopes, I shift from a higher gear to a lower one, and as the engine RPM increases, it naturally creates resistance, slowing the car down. This is much better than constantly using the brakes, especially on long descents to avoid brake overheating and failure. I've also found it saves brake pads and reduces wear, suitable for any road condition. When operating, it's important to match the vehicle speed and avoid forcefully downshifting at high speeds to prevent engine damage. I've been practicing this habit for over a decade, and it has made my driving more stable and safer.
