What do emergency braking and engine braking mean?
1 Answers
Here is the relevant introduction to emergency braking and engine braking: 1. Emergency braking: Emergency braking, also known as emergency braking, is the vehicle's second braking system, used when the driving braking system suddenly fails. So what should you do if the brakes suddenly fail? At this time, emergency braking needs to be used. For vehicles using compressed air, because the rear axle uses a dual-chamber brake air chamber, the parking brake is naturally used as emergency braking at the same time. Some vehicles use the rear axle brake as the hand brake, which also serves as emergency braking. 2. Engine braking: Engine braking refers to lifting the accelerator pedal without stepping on the clutch, using the compression resistance, internal friction, and intake and exhaust resistance generated by the engine's compression stroke to form a braking effect on the driving wheels. Engine braking makes full use of the engine's drag to control the speed. This method is most commonly used in mountainous areas, where descending large mountains or steep slopes frequently using the brake can cause the brake to overheat, easily leading to reduced braking efficiency.
