What are the benefits of engine braking?

[Eleanor]

It helps to slow down or stop in time to ensure driving safety; using engine braking can effectively reduce the frequency of using foot brakes, avoiding the temperature rise of brake friction pads due to prolonged use, which leads to a decrease in braking force. The following are specific explanations about engine braking: 1. Principle: During normal driving, the throttle supplies fuel, the engine is the active part, the car is the passive part, and the engine drives the car to run faster or maintain a constant speed. If the throttle is released after the speed increases, the car becomes the active part, the engine becomes the passive part, the car drives the engine to rotate, the speed gradually slows down, and the engine becomes a burden instead. This is engine braking. 2. Specific method: This is commonly known as "downshifting," which can be used in emergency situations when the brakes fail. Press the clutch, shift into neutral, release the clutch; step on the throttle to rev the engine; press the clutch, shift into a lower gear, release the clutch. (Revving the engine in neutral is to quickly increase the engine speed in a short time to match the vehicle speed, otherwise the speed difference between the two is too large to shift into a lower gear.)
