Can an automatic car coast in D gear instead of N gear while driving? Why?

Cars with automatic transmission cannot change D to N gear while driving.

On the one hand, coasting in neutral is because it is easy to cause traffic accidents, especially when going downhill, coasting in neutral is likely to make the vehicle unable to brake urgently.

As a result, it is out of control and causes major traffic accidents. In addition, regardless of the automatic transmission.

It is still a manual transmission, and it is illegal to slide in neutral.

It is also prohibited in the traffic law, and it is not possible to achieve fuel economy by taxiing in neutral gear.

Automatic carsYou can't coast in neutral, first of all, because it's very dangerous. When driving the vehicle, coasting in neutral gear in N gear will make the vehicle unable to slow down through the transmission system, so that in the event of an emergency, it is difficult to stop in time. It is very easy to cause traffic accidents and is a very dangerous behavior; Secondly, coasting in neutral is illegal.

Whether it is a manual transmission or an automatic transmission, as long as it is illegal to slide in the middle gear while driving, according to the provisions of the Road Safety Law, driving the vehicle to slide in neutral gear will be fined 200 yuan, and if it causes more serious consequences, it is also necessary to bear the corresponding responsibilities and consequences; Finally, coasting in neutral is harmful to the car. Many people think that neutral coasting is fuel-efficient, but in fact, neutral coasting cannot achieve the purpose of fuel saving at all, and may also affect the clutch and gearbox of the vehicle.

Driving a vehicle in neutral gear is easy to cause traffic accidents, especially when going downhill, neutral coasting will greatly reduce the braking performance of the vehicle, which can easily lead to accidents. <>

According to the provisions of the Road Safety Law of the People's Republic of China, drivers will be fined 200 yuan if they slide in neutral gear, and if they cause more serious consequences due to neutral coasting, they also need to bear corresponding responsibilities. <>

In fact, coasting in neutral does not achieve the effect of fuel saving, but in some cases, it will cause damage to the vehicle's engine, transmission and clutch, so that the gains outweigh the losses.

No; Because in this way, the parts of the vehicle can not be lubricated while driving, and it is also clearly stipulated that the automatic transmission vehicle can not slide, which will increase the wear and tear of the gearbox, reduce its service life, and also heat up the parts of the gearbox and cause damage in the process of coasting.

No, this will cause serious problems to the vehicle and will cause towing, which is a neutral slide and will cause damage to the gearbox.

No, as this may damage the parts, and the parts will not be adequately lubricated, it will also affect the gearbox, which will ultimately shorten the life of the gearbox.

No, you can't. Because the vehicle cannot coast in neutral while driving, such behavior may cause accidents in the vehicle.

If the D gear is pushed to the N gear in the running state of the car, the passive components that are running at high speed will not be adequately lubricated, which is why automatic transmission vehicles are not allowed to tow long distances. But in reality, there are many drivers who habitually do it, thinking that they can save fuel, but in fact, the gains outweigh the losses.

Automatic transmission, as the name suggests, is not used by the driver to change gears according to the speed and road conditions of the vehicle, and the vehicle will automatically choose the appropriate gear according to the speed and traffic conditions.

Vehicles with automatic transmissions are strictly forbidden to coast in neutral gear, and can only change gears to N when the vehicle is stopped. Shifting to N gear in an automatic transmission will accelerate transmission wear and tear and reduce the life of the transmission. Do not put the gear knob to the N gear position during driving, because the internal parts of the automatic transmission need to be lubricated, and when the gear is placed on the N gear during driving, the oil pump can not supply oil to lubricate normally, which will cause damage to the temperature of the internal parts of the gearbox.

After the vehicle is stopped, you need to put the gear knob in N or P gear.

Is there any damage to the car if the automatic transmission car is driving at high speed and is mistakenly hung into N gear? Can I switch directly to D gear?

N and D gears can be directly switched (no need to step on the brakes, no need to press the unlock button on the gear knob) You can also switch to N while driving, but the automatic transmission requires that you cannot switch to N gear while driving, because the N gear transmission does not supply oil, and the N gear will wear out the gearbox when driving.

Summary. Automatic transmission models are like this, this is a normal phenomenon.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

The car with automatic transmission can definitely coast in this D gear. It is in the process of hanging into the D gear driving judgment cover, and after it releases the throttle, it is a number of D gear coasting. Without a gas pedal, it's coasting in D gear.

However, the automatic transmission car can not coast in neutral gear, and in the case of neutral coasting, if it slides for a long distance, the gearbox will be damaged.

Recently, when I was sliding, I felt like my speed had dropped so much that I felt like something was pulling.

Automatic transmission models are like this, this is a normal phenomenon.

I thought it was caused by the D-gear slide.

This is not, this has nothing to do with it, this is a normal phenomenon, and it can be opened normally.

Oh, thanks.

The automatic transmission car can not be mounted in N gear to slide, which will damage the car's gearbox, and the automatic transmission car can not be slid in N gear. When the car is moving, the speed of the engine and the input shaft speed ratio of the automatic transmission will be relatively high, once the gear is converted to N gear, it will cause the car engine to lose contact with the middle of the tire, and the internal hydraulic oil pipe of the automatic transmission will have insufficient vapor pressure; In addition, the normal lubrication of the transmission can not be carried out, which causes the operating temperature of the internal structure of the transmission to rise, increases the friction working pressure, and also endangers the internal friction plate of the transmission.

In the long run, the internal parts of the transmission will deteriorate first, and in more severe cases, the transmission will be damaged immediately. The engine itself will bring a certain pull-in effect, and with the brake pads, the brake deceleration of the car will be reduced. Moreover, it is easy for the neutral gear to slide the car to stop the fire, resulting in the failure of the brake booster drum and the reduction of the characteristics of the brake plate.

Hanging neutral is not fuel efficient, and sometimes even more fuel-efficient, and has to do with the working condition of the engine of a four-stroke car.

Under the premise of gearing, if the driver releases the throttle, the electronic computer will put the car into coasting mode, during which for a long time, the engine does not have a gasoline pump; If you coast in neutral, the computer will put the car into standby, and the engine will still be on the gasoline pump. That's why coasting in gear sometimes consumes more fuel. It can seriously affect the small clutch.

the efficacy of the clutch; The clutch connects the engine to the gearbox, and the engine propulsion input must be interrupted when the gearbox shifts; Because it can be extracted and recombined for the gear set to decelerate, it is easy to make teeth if the speed is too high. This process is the "release" of the clutch, and the "closure" is the release of the clutch spring shock absorber after the gear is completed, and the nut puts pressure on the clutch plate so that it only obeys the engine axle tenon.

The driving force of the gearbox comes from the inertia force that pushes the vehicle to move, and the gearbox is pushed by the wheels and drive shaft to push the gearbox in reverse, which is also very easy to cause damage. Neutral coasting is not fuel-efficient, and sometimes even more fuel-efficient, and is mainly related to the working condition of the four-stroke car engine. Four-stroke car engines can also distinguish more and less oil pumps according to the computer system.

It is not allowed to coast in N gear, which will not only damage the gearbox of the car, but also have a very serious impact on the life of the car and the subsequent driving, and will also cause some functional damage.

Of course not, because this kind of neutral coasting will bring some harm, and it will also lead to a reduction in the life of the car. And not only the gearbox will be damaged. It can also damage the oil, but it can also damage the car's engine, and it can also damage the brake pads.

Automatic cars cannot be put on N gear to coast; This will affect the lubrication and heat dissipation function of the gearbox, which will cause friction and damage to the car, and we should drive it well.

Of course not, such behavior is also very dangerous. It will definitely damage the transmission of the car, and it will also cause damage to the engine of the car.
