What does it mean to be in P file N file D file R file?

P file. It means parking stalls. When this gear is engaged, the parking locking mechanism locks the transmission output shaft.

R gear: It means reverse gear. When this gear is engaged, the hydraulic system is switched on.

Reverse gear oil circuit, so that the driving wheel reverses, reverse gear driving. When the vehicle is not completely stopped, do not force it to turn into "R" gear, otherwise it will cause damage to the transmission.

n gears. Meaning gap. When engaged in neutral, planetary gears.

The system idles and cannot output power.

D file. It means forward gear. When the shift lever is in this gear, the hydraulic system control device will automatically connect the corresponding forward gear oil circuit according to the throttle opening signal and the vehicle speed signal, and can automatically raise and lower gears with the change of driving speed to achieve automatic transmission function.

S gear: It means sport mode. When the shift lever is in this gear, the transmission control module receives the driver's instructions, and then the vehicle enters the sport mode, the shift logic will be more aggressive, and the gear changes will be more frequent, giving the driver a better sense of control and throttle response, which can reflect the driving pleasure of the vehicle.

Automatic principle:

The power of the engine is transmitted through the gearbox, which is also a key indicator of fuel consumption, and in general automatic transmissions.

The fuel consumption is more than 10% higher than that of manual transmission. It doesn't matter if it's manual or automatic.

The more gears, the more fuel-efficient.

The automatic transmission uses a planetary gear mechanism to shift gears, and it automatically shifts gears according to the degree of the accelerator pedal and the change in vehicle speed. The driver only needs to control the speed of the vehicle by manipulating the accelerator pedal.

Generally speaking, there are the following types of automatic transmissions commonly used in automobiles: hydraulic automatic transmissions, hydraulic transmission automatic transmissions, electric transmission automatic transmissions, stepwise mechanical automatic transmissions and continuously variable mechanical automatic transmissions.

The most common is a hydraulic automatic transmission. The hydraulic automatic transmission is mainly composed of a hydraulically controlled gear transmission system, which mainly includes two parts: automatic clutch and automatic transmission. It automatically shifts gears according to the opening of the throttle and changes in vehicle speed.

Nowadays, car lovers like to buy automatic transmission, and everything is simple to drive, and the automatic transmission car is more complex in configuration, and the cost of maintenance is higher, so you can't be too casual when you usually drive, especially the gear can not be used indiscriminately.

P, N, D, and R are all automatic gears, of which P is the parking gear, N is neutral, D is the driving gear, and R is the reverse gear.

The details are as follows: 1. P parking gear.

When the parking is not in use, the gear position is here, and at this time the wheels are in a mechanical lock state, which can prevent skidding.

2. R gear reversing gear.

As the name suggests, it is used to reverse the car.

3. N gear neutral.

Use this unit when stopping temporarily, such as at a red light. Note that this gear means neutral. To prevent the vehicle from slipping on slopes, be sure to apply the brakes.

4. D gear forward.

Also known as drive gear. That's the time to move forward, using this device.

Hello dear, glad to answer for you. P file n file D file R file means: p:

The word p represents the section of the eggplant is park, which means park, parking in Chinese. This gear is also called parking, and it is the gear hand burning position when parking. n gears.

The word n stands for neutral, and Chinese means neutral, neutral, neutral. This gear is called neutral and can be used when starting or when towing or temporarily stopping (such as a red light). d:

The word d stands for drive, which means to drive forward, to drive forward in Chinese. This gear is called Forward gear. When the car starts, it needs to be in D gear.

The whole car is automatically shifted by the gearbox. As a driver, you only need to control the steering wheel, accelerator, brakes. R file:

The word r stands for reverse, which in Chinese means Bibi anti, anti, anti. This gear is also called reverse gear. When you want to reverse, put this gear on and the car will reverse back.

Hello! P, N, D, and R gears are common gears in automotive automatic transmissions. Among them, the P (parking) gear is the "parking gear", and when the year Qi Dispersion needs to stop, the gear lever is directly dialed to the P gear, that is, the vehicle can be parked in place.

N (neutral) is the "neutral gear", which can be moved to the N gear lever when the vehicle needs to be temporarily stopped, or when it needs to be operated by a cart or trailer. D (Drive) is the "Forward Gear" and is used for vehicle driving. When the gear lever is shifted to D gear, the car moves forward, increasing or decreasing the speed of the vehicle according to the size of the throttle.

R (Reverse) gear is a "reverse gear", and when it is time to reverse, turn the gear lever to R gear to reverse the vehicle. It should be noted that when reversing, it is important to observe the rear situation to ensure safety. There may be differences between different types of car gear levers, but the above is generally applicable to the automatic transmissions that are common in the wingers.

Dear, I'm glad to answer for you that the general automatic transmission model has five gears: P, R, N, D, and S. Among them, P gear is the parking gear, N gear is the gear, D gear is the forward gear, and R gear is the car reversing gear. The driver needs to engage the corresponding gear to complete the corresponding operation when driving.

The following is the relevant introduction: 1, P gear is the dust culture parking gear closed brother: when the vehicle does not need to be used or parked for a long time, put the gear in the P gear, at this time the vehicle is in a state of mechanical locking, which can effectively avoid the phenomenon of the vehicle slipping. 2. R gear is a reverse gear:

When it is necessary to reverse, the vehicle can be reversed by engaging the gear. 3. N gear is neutral: when using N gear, it needs to be used with brakes, so as to avoid the phenomenon of slipping.

4. D gear is the forward gear: the vehicle will drive forward only when the gear is engaged. 5. S gear is the sports mode

This gear can be used when overtaking or when going uphill, but it will consume more fuel.

Hello, P gear N gear D gear R gear means: P is the parking gear: the car stops after the engine is turned off, and the car will be hung into the Xiqi P gear.

N is neutral: automatic transmission cars are marked with N gear, while manual transmission does not have N gear marking, in fact, N gear is equivalent to the neutral gear of manual transmission. The car is engaged in N gear, the engine of the car is disengaged from the gearbox, and the power transmission is interrupted.

D is the forward gear: after the automatic transmission car is hung into the D gear, after letting go of the handbrake and foot brake, the car will drive in front of Kaihuai, while the manual transmission car actually needs to be hung into the first gear to realize the function of staring at Luyou to drive forward. r is the reverse gear:

When the car is reversing, put the gear lever into R gear, and the car will drive backwards, which is the same as the manual R gear.

P gear is parking, N gear is neutral, D gear is forward gear, and R gear is reversing gear, P, N, D, R these gears are basically available in every automatic transmission car. The vehicle can only be started in P and N gears, and the lever taken off from P gear must be applied to the brakes. The use of N-gear start is that when starting the vehicle to drive directly forward, you can first turn on the power (do not touch the engine), step on the brake to pull the gear to N-gear, and then ignite, and drive directly forward after hanging the D gear.

This prevents the P gear from catching fire, and needs to pass through the R gear to make the gearbox reverse impact through the chatter. Another effect is a sudden flutter while driving, which can be quickly pushed to N gear to ignite and then start the engine when it is safe to do so.

Precautions for driving an automatic transmission car

1. Be careful not to have an insight into the slide, many drivers think that the neutral slide can save fuel, but this practice is wrong, the automatic car hangs the neutral slide and can not achieve the effect of fuel saving, and the long-term neutral slide will lead to insufficient oil pressure in the hydraulic pipeline in the automatic transmission, which will not only increase the friction and reduce the lubrication effect, but also damage the friction plate inside the automatic transmission.

2. Parking gear should be noted, if you need to park, the automatic transmission owner and the manual transmission owner parking is completely different, automatic transmission model parking or long-term idle parking, is to first step on the brake, and hang into the n gear, and then pull on the handbrake and release the brake pedal, when the vehicle stops, hang into the P gear.

3. When towing a truck, it should be noted that if you drive an automatic transmission car on the road and need to tow it, under normal circumstances, the automatic transmission model is best to hold up the whole vehicle, 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 minimize the distance of the end towing and keep the speed low.

Summary. Hello dear, glad to answer for you.

The P file is the "program mode", which is a semi-automatic mode, the camera will automatically adjust the aperture and shutter values for you, you only need to adjust the ISO and ** compensation. This mode is suitable for users who want to master some freedom but don't want to fully grasp every detail. The N stop is the "Shutter Priority Mode", which is a semi-automatic mode that allows you to manually set the shutter speed, and then the camera will automatically adjust the aperture and ISO values for you to match your options.

This mode is useful when you need to control motion tracking. The D stop is "Aperture Priority Mode", which is also a semi-automatic mode, except that it allows you to manually select the aperture size and the camera will automatically adjust the shutter speed and ISO value for you to match your options. This mode is suitable for those who need to master the depth of field when shooting.

The R mode is "full manual mode", in which the camera does not give any assistance, and all parameters need to be set manually by the user. This mode is suitable for advanced users or those who use special lighting or shooting modes.
