What is the harm to the engine if the speed is very high when braking the engine down a long slope?

For ordinary family cars, increasing the braking speed of the engine will not cause any damage to the engine, but for large trucks, the restraining effect on the speed in the process of engine braking is more obvious, and it will also cause certain damage to the engine.

The speed ratio will be very high when the engine brakes on the growth downhill road. What is the damage to the engine? It is not easy to cause damage. In the case of going down a long slope, it is right to use the engine to brake, instead of stepping on the brake pedal, which is very easy to cause uncontrollable side slips, and in serious cases, it is very easy to cause brake failure.

Using engine resistance to control the speed measurement will lead to an increase in engine speed, which theoretically will produce certain impact and wear.However, when the engine heats up and the lubrication system is established, this kind of wear can be ignored.

Is there any damage to the engine by using engine braking

No damage. Frequent use of the transmission will cause damage to the engine. The engine brakes by downshifting, and the transmission is subjected to the greatest force. It's better to slow down first and then downshift. Using engine braking for long-distance downhill can effectively reduce braking thermal attenuation.

No damage. Frequent use will damage the transmission engine. Engine braking should be done by slowing down. The greatest force is the gearbox. It's better to slow down before slowing down. The use of engine braking for long-distance downhill can effectively reduce the thermal attenuation of braking.

no damage. Frequent use of pairsThe speed box will damage the engine. Engine braking should be done by downshifting. The most powerful thing is the gearbox. It is better to slow down first and then downshift. Using engine braking on long-distance downhill can effectively reduce brake thermal attenuation.

How to make reasonable use of engine braking

startMechanism method: Predict braking is to relax the accelerator pedal in a planned and purposefully manner at the situation point in advance, use the natural resistance to slow down when driving, and step on the brake pedal intermittently and gently according to the situation to further slow down or stop. This is the most commonly used braking method for safe driving.

When slippery roads such as slag oil road surface, muddy ice and snow road surface, engine brake should be used as much as possible, parking brake should be used flexibly, and foot brake should be minimized. If you use foot braking, it is better to use intermittent braking. Don't step on it with your feet to prevent side slipping.

If you use foot braking, it is better to use intermittent braking, and do not step on it to prevent side slipping.

First of all, the automatic parking system is suspended in gear without fuel. In this case, the car engine does not drive the car, and the wheel rotation pushes the car engine instead. In this way, the car engine has a reaction force to the car, which can play the effect of the braking system.

Use the engine to brake. Whether to the engine. The gearbox is harmful

1. No damage. Frequent use of the transmission will cause damage to the engine. The engine brakes by downshifting, and the transmission is subjected to the greatest force. It's better to slow down first and then downshift. Using engine braking for long-distance downhill can effectively reduce braking thermal attenuation.

2. No damage. Frequent use of the gearbox will only the engineIf there is damage, the engine braking should be done by downshifting. The most powerful thing is the gearbox. It is best to slow down first and then downshift. Using engine braking on long-distance downhill can effectively reduce brake thermal attenuation.

3. No damage. Frequent use will damage the transmission engine. Engine braking should be done by slowing down. The greatest force is the gearbox. It's better to slow down before slowing down. The use of engine braking for long-distance downhill can effectively reduce the thermal attenuation of braking.

4. Frequent use of the gearbox will cause damage to the engine. The engine brakes are downshifted, and the gearbox is subjected to the greatest force. It's best to slow down first and then downshift. Using engine braking for long-distance downhill can effectively reduce braking thermal attenuation.

5. It doesn't seem to be very harmful to the engine itself. What is harmful is the damage to the engine support and engine foot mat.Frequent use is harmful to the gearbox. Engine braking should be done by downshifting. The most powerful is the gearbox. It is best to slow down first and then downshift.

6. The use of gearbox braking is only an auxiliary to brake braking, which is to avoid brake failure caused by long-term and long-distance braking due to thermal attenuation. Therefore, when driving a low gear downhill to help slow down, it should be well coordinated with the brakes, and there is no harm to the gearbox.
