Automatic transmission, can you hang N gear when walking, coasting.

Resolutely put an end to this kind of operation, which will damage the planetary gears, and seriously lead to the scrapping of the gearbox Gliding in neutral gear is nothing more than to save fuel Now the cars are EFI, when you completely release the throttle at the same time, the electronic control system will automatically take oil cut-off protection to reduce fuel consumption, and the automatic transmission car is even more so When the throttle is released, the nozzle will stop the injection of gasoline into the cylinder, and when the speed drops to a certain level, the electronic control unit will let the nozzle resume fuel injection, and at least ensure the operation of the engine at idle speed The automatic transmission car can not only reduce fuel consumption by sliding in N gear, but also damage the gearbox, resulting in increased gear wear, which outweighs the loss

Why is it dangerous to coast in N gear in automatic transmission!

It is still necessary to start with the manual transmission, the manual transmission can slide, but if you want to hang the gear, you can choose the gear to be hung according to the speed at that time, which is the advantage of the manual transmission. Automatic, on the other hand, is programmed, and once you change it from D to N, it's the same glide, which isn't really the root of the problem. But if the car does not stop, you have to push from N gear to D gear can be considered, the automatic box is according to the situation at the beginning of the selection of 1st gear gear, if the car speed is relatively fast at this time, then the gearbox must be burned.

It's like when a manual gear is coasting at a speed of 50 km/h from neutral, and you force it into the 1st gear tyre clutch (of course, you need a lot of force), and the teeth on the gears are hard to protect. The automatic transmission is the most afraid of shock, and it is easy to burn the gearbox, because the automatic transmission is not easy to repair, so it is generally replaced. An automatic gearbox costs tens of thousands.

Don't !!

Then your transmission will be scrapped.

Because the automatic transmission car is geared, it is lubricated by splashing. If it is hung in n gear, there is no oil to lubricate it. Very easy to break.

Added: Gliding is not fuel-efficient.

Yes.

Because the automatic transmission needs lubrication, when the gear is placed on the n during driving, the oil pump can not supply oil normally for lubrication, which will increase the temperature of the internal parts of the gearbox, causing complete damage, and it is also very dangerous to coast in neutral gear at high speed, and it is not fuel-efficient.

Automatic transmission car driving wrong practices.

1. Hang P gear before the car stops.

Friends who have driven an automatic transmission car know that the P gear parking gear, when parking and getting off the car, the parking gear is the P gear, but you must know that the car is not parked and can not be hung in the P gear, There are many impatient drivers, when the car has not completely stopped, first on the P gear.

Although the gear is parked at this time, but the car is not gasped and stopped, which will cause some damage to the car transmission, after the P gear is hooked, the transmission gear is locked, and the state of stop begins, but if it is not stopped and corrected position, the transmission will bear the burden.

2. Always use D gear when driving.

When driving, the road cannot be a smooth road, and the power output required by the road is uncertain, which means that we want to ensure the normal output of the vehicle's engine. If necessary, use other gears, such as when driving uphill, you should be engaged in L gear, which should be a climbing assist gear, and the power will be different when going uphill.

It won't hurt the car, but it's not necessary. Gliding in N gear is nothing more than trying to save fuel. But what I want to say is that not only is this not fuel-efficient, but it may be more fuel-efficient.

Let's not talk about the safety hazards. We all know that the trip computer will inject fuel based on our speed and throttle pedaling. When coasting, when the gear is in gear, the engine will not inject fuel within a certain speed without stepping on the accelerator.

You can look at the instantaneous fuel consumption)

Automatic cars cannot coast in N gear. In the process of high-speed driving, the speed of the engine and the output shaft speed of the automatic transmission will be very high, once the gear is switched to N gear, it will cause the loss of contact between the engine and the wheels, and the hydraulic pipeline inside the automatic transmission will also have insufficient oil pressure;

As a result, the gearbox cannot be lubricated properly, resulting in an increase in the operating temperature inside the gearbox, increasing the friction pressure, and also damaging the friction plates inside the gearbox. In the long run, the internal parts of the gearbox will age prematurely, and in serious cases, the gearbox will be scrapped directly.

Hello, the automatic transmission can not be coasted in n gear, although the engine and the clutch power transmission has been cut off when hanging neutral, but the clutch gear is driven by the wheel at high speed, and the wheel speed connected with the engine is very low, the gap between the two is very small, easy to cause resonance and slippage, but also will lead to insufficient oil pressure in the hydraulic pipeline, increase friction, reduce the internal lubrication effect of the clutch, and even damage the gearbox body. Automatic transmission usually refers to the automatic shift mechanism of the car, and the control system of the automatic transmission automatically selects the appropriate gear according to the speed and load of the engine when driving, thus replacing the subjective judgment of the timing and shift operation of people.

Automatic cars are not allowed to coast in neutral gear.

The lubricating oil of the automatic transmission needs to be supplied by the engine, and the oil pressure output when the engine is idle will be relatively low, and at this time, the automatic transmission is dragged by the wheel operation and has been running the linkage, and the oil pressure is low, and the lubricating oil is less, which is easy to cause the hydraulic reversing valve in the automatic transmission.

Planetary gears and other components are poorly lubricated and seriously worn, and a large amount of heat is generated at the same time, and excessive heat will lead to the carbonization of the engine oil and the formation of sludge to block the complex oil passage, resulting in insufficient oil quantity after normal oil supply and poor lubrication. Therefore, the habit of coasting in neutral gear must not be used on automatic transmission models.

The issues that need to be paid attention to when driving an automatic transmission car are as follows:

1. The problem of switching gears when driving: automatic transmission cars are protected and interlocked for dangerous actions, if D gear is switched to R gear or P gear. Because these gears are unintentionally switched wrong, it is dangerous.

However, it is possible to switch between D and N gears at will, including while driving.

2. The slope will slip: If the automatic transmission vehicle is parked on a steep slope, its gravity is greater than the power "margin" at idling, the car will still slide, so for insurance, it is best to start with the handbrake.

3. Prohibit neutral sliding: many drivers think that neutral sliding can save fuel, but this practice is wrong, the automatic transmission of the car hanging neutral sliding can not achieve the effect of fuel saving, long-term neutral sliding will lead to insufficient oil pressure in the hydraulic pipeline in the automatic transmission, which will not only increase friction and reduce the lubrication effect, but also damage the friction plate inside the automatic transmission.

4. Parking gear should be noted: if you need to park, the automatic transmission owner is completely different from the manual transmission owner parking, when the automatic transmission model is parked or idle for a long time, it is necessary to step on the brake first, and hang into the N gear, and then pull on the handbrake and release the brake pedal, when the vehicle stops steadily, hang into the P gear.

5. Trailer: It is best to hold up the whole vehicle for automatic transmission models, if there is no way to tow the whole vehicle, then it is best to set the vehicle in the N gear position, and try to reduce the distance of the end tow and keep the speed low.

Hello, Happy New Year, dear, the car master for your service, attentive, careful, attentive to answer your car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! We hope you find this answer helpful. Happy Chinese New Year, Happy Year of the Tiger Hello friends, the automatic transmission of the car is not able to slide the first, automatic transmission of the vehicle, if the high-speed state of neutral sliding, this is easy to cause the transmission internal oil temperature is too high Second, if the neutral sliding, this is easy to cause serious wear and tear of the gearbox internal gear, which will lead to the gearbox can not run normally or the gearbox is scrapped.

Automatic transmission cars cannot slide in N gear, otherwise it will affect the lubrication and heat dissipation of the gearbox. When coasting in Nth gear, the oil pressure of the automatic transmission will decrease, which will seriously affect the lubrication and heat dissipation of the transmission. If you slide in N gear for a long time, it is easy to cause the transmission to burn out.

Manual transmission cars also can't coast in N gear.

N gear is the gear used when stopping for a short period of time without turning off the engine.

When the gearbox is engaged in nth gear, the connection between the gearbox and the wheels will be disconnected. At this point, the power of the engine cannot be transmitted to the wheels, making the car unable to drive.

But after engaging the Nth gear, the car can move if the handbrake is not pulled.

Automatic cars also have a P gear, which is a parking gear that is used when parking is turned off.

When the P gear is engaged, the P gear locking mechanism in the automatic transmission locks the gears of the transmission, which is equivalent to an indirect locking of the wheels.

After engaging in P gear, the brakes cannot be moved without holding hands.

However, it is recommended that you tighten the handbrake after hanging the P gear, otherwise the pressure of the P gear locking mechanism is too large, which will cause the P gear locking mechanism to be damaged.

Do not engage the P gear while driving, otherwise the locking mechanism of the P gear will be damaged.

When waiting for the red light, you can put it in N gear, but it is not recommended to put it in P gear.

I'm a Fit rider, and the Fit automatic transmission can't coast in neutral gear, otherwise it will cause the gearbox to overheat. This in turn leads to transmission failures, such as satisfaction.

Can an automatic transmission car coast in N gear Automatic transmission cars cannot be attached to N gear to slide, otherwise the lubrication and heat dissipation of the gearbox will be affected. When coasting in Nth gear, the oil pressure of the automatic transmission decreases, which causes the lubrication and heat dissipation of the transmission to be severely affected. If you slide in N gear for a long time, it is easy to cause the gearbox to burn out.

Manual transmission cars are also not allowed to slide in N gear.

N gear is used when parking for a short period of time without turning off the ignition.

When the Nth gear is engaged, the connection between the gearbox and the wheels is disconnected, and the power of the engine cannot be transmitted to the wheels, so that the car cannot drive.

But when the Nth gear is engaged, the car can move without pulling the handbrake.

Automatic transmission cars also have a P gear, which is a parking gear, which is used when parking and turning off the engine.

After engaging the P gear, the P gear locking mechanism in the automatic transmission will lock the gears of the gearbox, which is equivalent to indirectly locking the wheels.

It is also impossible to move without pulling the hand brake after engaging the P gear.

However, it is recommended that you tighten the handbrake after hooking the P gear, otherwise it will cause the pressure of the P gear locking mechanism to be too large, which will cause the P gear locking mechanism to be damaged.

Do not engage the P gear when driving, otherwise it will also cause damage to the P gear locking mechanism.

When waiting for a red light, you can put it in the n gear, but it is not recommended to put it in the p gear.

Can an automatic car coast in D gear.

Automatic cars can coast in D gear. However, the automatic transmission car cannot be attached to the N gear to slide, otherwise it will affect the lubrication and heat dissipation of the transmission. If you slide in Nth gear for a long time, it is easy to cause the automatic transmission to burn out.

When you use an automatic transmission, you must maintain the correct habits of use.

There are three types of automatic transmissions commonly found in automobiles, which are AT transmission, dual-clutch transmission, and CVT transmission.

The dual-clutch transmission is based on the manual transmission, which only has one more clutch and one shift control mechanism than the manual transmission.

One set of clutches in a dual-clutch transmission is used to control odd-numbered gears, and the other is used to control even-numbered gears.

AT transmission is the most mature technology and the most widely used automatic transmission.

There are many planetary gears inside the AT gearbox, and this kind of gearbox uses planetary gears to change speed and torque.

The AT gearbox is connected to the engine by means of a torque converter.

The CVT gearbox is a kind of automatic transmission with a relatively simple mechanism, and this kind of gearbox has only two taper wheels and a steel chain inside.

The steel chain of the CVT gearbox can be moved on the cone pulley, so that the gearbox can change the speed and torsion.

The smoothness of the shift of the CVT gearbox is relatively good, and the reliability and durability are also relatively good. (Photo by Q&A: Q&A called the beast) @2019

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.
