How to understand high end and low gear?

The difference between low gear and high gear is that the low gear has a lot of torque and the top speed is small, while the high gear is the opposite.

The gear is used to change the torque and speed of the engine crankshaft to meet the needs of the different requirements of the driving wheel traction and vehicle speed under different driving conditions such as starting, accelerating, driving and overcoming various road obstacles, so that the car can drive at a very low stable speed, and this low speed is difficult to achieve only by the minimum stable speed of the internal combustion engine.

How to understand high-end and low-gear? Low-grade generally refers to gear, and high-grade generally refers to more than 3 gears. Because the torque in the gear position can overcome the greater resistance, the vehicle generally has to be in gear when starting and climbing steep slopes.

High-speed driving can easily cause carbon deposits inside the engine. When carbon deposits reach a certain level, it will lead to difficulty in starting the vehicle, increased fuel consumption, reduced engine power, and weak acceleration. The engine computer has a self-learning function and will remember this driving habit, so the car will be weak in the future.

Hazards of low speed: driving at low speeds, the same mileage, requires the engine to turn several times. The more the engine revses, the greater the wear and more gasoline consumption.

Run the same distance in 2nd and 5th gear, and at least double the number of revolutions in 2nd gear. @2019

The gears are different: The big gear instead of the small gear, and the small gear instead of the big gear. The 1st gear revs slowly, but the torque is great, so climbing, pulling heavy loads, usually requires a low gear, while the 5th gear has a small torque, but the speed is fast, so run high speed with it.

In the case of not dragging the gear, the low-speed high-end position is more fuel-efficient, and the various parts of the engine will also produce resistance when running. The higher the rotational speed, the greater the resistance. The resistance at 2000 rpm is definitely less than at 3000 rpm, so a slightly lower rpm speed during driving can reduce the power consumed by the engine itself and help reduce fuel consumption.

Precautions for driving a car.

Avoid downshifting and not blowing up empty oil: when downshifting, in the gear with synchronizer, you can also reduce the gear without adding empty oil and a foot clutch, but it is easy to wear out and damage the parts early, so it is recommended that regardless of whether there is a synchronizer or not, the vehicle should use a two-foot clutch and add a foot of empty oil to reduce the gear.

Do not drive with low speed gear for a long time: If you drive at low speed for a long time, the speed is low but the speed is high, and the mileage per unit time is small, which will increase fuel consumption relatively, so it is recommended that after the vehicle starts, as long as it is not a low-temperature cold car, the gear should be raised to the appropriate level as soon as possible. Generally speaking, high-speed gears are more fuel-efficient than low-speed gears.

The dual-clutch transmission you are talking about refers to is a dual-clutch transmission, which is a relatively advanced kind of automatic transmission, and the manual automatic operation is only a method, of course, the dual clutch transmission can also be operated by manual automatic operation.

Dual-clutch transmission English abbreviation DCT transmission, he refers to the transmission has two clutches, one controls odd gears, one controls even gears, so that when changing gears, the two clutches are switched successively, and the clutch of odd gears has not been completely disengaged in the case of even gears has entered the work, so that the car's power is not interrupted, so that the vehicle is more stable when changing gears, and the impact of shifting is very small.

Manual automatic refers to the manual transmission mode and automatic transmission mode, they are controlled by the on-board computer, in the automatic mode, the vehicle reaches the specified speed, engine speed, and throttle opening, and other data, the computer will control the transmission shift. In manual mode, you can control the gear shift yourself via the shift knob. Of course, the automatic transmission has a self-protection program, and you can only operate it manually within this protected range.

For example, in manual mode, when accelerating, your engine revs are too high and you haven't shifted gears, and then the shifting will automatically give you a shift. When decelerating, your engine speed is very low, and you haven't changed gears yet, which transmission will automatically lower the appropriate gear for you.

In fact, both manual mode and automatic mode have their own uses, depending on how you operate it. If it's faster than accelerating in a straight line, it's sure that the automatic mode responds faster, and if it's faster than mountain roads, climbing, or overtaking, I think it's still faster than manual mode.

Paddle shift is a quick shift method invented for the human hand not to leave the steering wheel, the same as the manual mode shift, which was first used in racing cars, and has now entered civilian vehicles. The shift response speed is the same.

I don't know if you understand what you said, I have driven all these types of cars as you said, I used to be a professional test driver and technician, I have driven all kinds of cars and repaired them, and I have run all the tracks in the country. The views expressed above are mine only and do not represent the views of all people.

The manual automatic transmission is an automatic transmission.

The manual automatic only adds a few buttons that can be controlled manually, and the gear lever of the automatic transmission is like a computer keyboard.

The automatic clutch pedal is rarely used in driving, because the automatic manual is an automatic transmission. Unless the automatic transmission is faulty, it can be changed manually.

Manual self-integration is not a manual transmission after all.

If you want to open the manual automatic, you have to completely delete the function of the manual gear.

How can the hand be integrated into one, it is still an automatic transmission after all.

If you want to open a manual transmission, you can directly buy a car with a pure manual transmission.

Dual clutch means that there are two clutches, and manual gears can also have two clutches, but it is not necessary to be too high, so there is no one on the market.

Manual automatic transmission, that is, with manual touch automatic transmission, manual automatic integration can be single clutch, can also be double clutch.

The manual mode under the virtual manual computer of the hand automatic, there is still no clutch, it is not right, the car should have a clutch, otherwise you can't brake the car when you hang up the gear, otherwise the ignition will be turned off.

Manual mode is not really manual gear has a feeling, but not to respond very slowly, unless it was not done many years ago, paddle type and manual mode are the same, just to operate on the steering wheel, it feels very good.

In fact, it has been used many years ago in low-end cars such as Buick business vehicles, and there is no feeling of slowness.

Strictly speaking, only manual and automatic transmissions can be understood.

Neither the dual-clutch nor the manual automator are well understood. Is there anyone who can explain it in simple and understandable words.

What is the difference between a dual-clutch and a manual automatic?

I heard a friend say that the manual mode under the virtual manual of the manual computer is still without a clutch, and there is no gear for you to call! Even cut into manual mode, the response is slower than that of automatic transmission. Not sure if that's the case.

In addition, there is paddle shifting on the supercar. Some people say that it is the same as the hand is one, and some people say that it is different. But at least after checking, although the paddle shift is not as fun as the traditional manual gear shift, it is also launched by F1 in order to reduce the mistakes in shifting and reduce the shift time!

It can't be slower than before? Solving!

Professional saying: manual automatic integration is referred to as manual automatic integration, dual clutch is collectively referred to as DSG, and continuously variable transmission is collectively referred to as CVT.

The so-called manual self-integration, with a hydraulic coupler, planetary gear shift group, double clutch is two sets of computer-controlled clutches, control two sets of gears, one group of odd gears and one group of even gears, after hanging a group of gears, another set of gears on standby, one clutch disengaged, the other combined, it will instantly complete the shift. Because it is a direct transmission of power, it avoids the problem of low transmission efficiency of the hydraulic coupling and saves fuel. However, if the DSG gearbox is in a semi-linkage state for a long time in a traffic jam, it will have a certain impact on the service life.

Modes Pros and Cons.

Manual; Fuel-efficient, with a sense of control, timely horsepower input; Some people find it cumbersome to operate.

Hand self-integration; Changeable operation mode fuel efficient, manual mode shifting, electronic shift does not have the feeling of mechanical shifting.

Automatic; Easy to operate, fuel-efficient, frustrating shifting.

Infinitely variable speed; Easy to operate, more fuel-efficient than automatic, no frustration; High cost.

dual clutch; Similar to the automatic transmission, but the shift speed is fast and the power is timely; High cost.

The 7-speed manual automatic transmission also belongs to the traditional step-by-step automatic transmission, but it only has a manual MT mode, but the automatic transmission also has a clutch, but it does not need to be controlled by a person, but when the vehicle reaches the rated speed and speed, the computer-controlled automatic transmission is raised from 1st to 2nd gear. The DSG gearbox adopts a dual-clutch design, and the shift speed is faster than the manual transmission, which is also the world's fastest automatic transmission than the manual transmission, but the operation method is very simple and the traditional automatic transmission is still the same, the gear is still P, R, N, D gear. The comparison between these two gearboxes is of course 7-speed DSG!

DSG is not only highly technological, it is much more advanced than the 7th gear manual automatic integration, and the performance is also better than the manual automatic integration.
