Do you need to step on the throttle to downshift, and why do you need to give the throttle to downsh

After downshifting, you definitely need to step on the accelerator, but it should be divided into the following two situations. Generally, when the vehicle needs to downshift during driving, it means that the speed has been reduced (or the speed has not come down but the speed cannot be increased in this gear, and the engine speed needs to be downshifted, and the engine speed needs to be increased and then upshifted to increase the speed). The need to shift from high speed to low gear also meets the driving needs of the vehicle.

Shift process, step on the clutch (manual transmission) - shift --- loosen the clutch. For example, when you are driving slowly on a city road or on a bumpy road, the purpose of downshifting now is to get the result of low speed, so you can stabilize the throttle after changing gears and keep the car at its current speed. If you can't climb while climbing, and you feel that the power is insufficient, you need to downshift to increase the engine speed and increase the torque output, so you need to give a larger throttle immediately after the shift operation to meet the speed increase of the vehicle.

So the vehicle must step on the accelerator when changing gears during driving. There is only one exception, when the engine can maintain the most basic idle speed on its own without stepping on the accelerator pedal after shifting neutral.

Hello, when the vehicle downshifts, this does not need to step on the accelerator, you just need to reduce the speed to the appropriate range, and then directly step on the clutch gear, no need to go to the gas pedal again.

Hello owner, the vehicle needs to brake and decelerate first, and when the speed is lowered to downshift, then step on the clutch to shift, the whole downshift process does not need to step on the accelerator, if you need to use the engine brake to slow down, then you can also step on the clutch to slide in low gear.

Hello, the vehicle needs to apply the brakes when downshifting. Wait until the speed of the vehicle has dropped to a certain level before downshifting.

Downshifts are required because the gears must match the speed of the vehicle.

In the process of driving, it is very important to change gears in time, and if the gear is too high and does not match the actual speed, it is a kind of "high gear and low speed" behavior, which is the so-called "drag gear". To put it simply, it is to drive at low speed in high gear, and the engine keeps the engine very low.

For example, when the speed is 50 kilometers per hour, it is most appropriate to hang into 3rd or 4th gear, but you have to hang on to 5th gear.

The hazards of automatic transmission cars at high speed and low gear.

1. Severe wear of the engine and clutch.

High-grade low-speed is to work in the state of unsuitable transmission ratio, at this time the engine speed is low but the load is high, when the high load is running, the moving parts such as the piston, connecting rod and crankshaft are under great pressure, resulting in wear, resulting in premature damage to the engine, and the clutch is also subjected to huge load, so that the clutch plate wears out in advance.

2. Carbon deposition is easy to occur at high gear and low speed.

In the low-speed working state, it is difficult for the car to play the self-cleaning effect of the engine, and it is easy to produce carbon deposits in the engine and oil circuit, and when the carbon deposits accumulate to a certain extent, it will also lead to the failure of the vehicle to start, the engine power decreases, the fuel consumption increases, and the acceleration is weak.

In 3-5 gear, if you don't step on the accelerator, the speed will be reduced, and it will be lower than the speed required by the gear, commonly known as "shifting", which is not allowedIt is necessary to downshift in time.

If it's 1-2 gear, don't step on the throttle, the speed will be reduced, and it will maintain to about 10 yards, which is okay, maintain 2nd or 1st gear.

A car that uses a manual shift mechanical transmission (also known as manual transmission, MT) to adjust the speed of the vehicle. That is, the gear lever can be toggled by hand to change the gear meshing position in the transmission and change the transmission ratio, so as to achieve the purpose of speed shifting. When the clutch is pressed, the gear lever can be activated.

Gear introduction. The first gear is the starting gear, and the car starts the gear. The performance is basically the same as that of the reverse gear, so it is not suitable for continuous high-speed operation. Generally, after the inertia of the vehicle movement, it can be shifted into second gear.

The second gear is mainly used to pass through complex road surfaces and deal with complex situations, such as through acute angles (right angles) bends without special obstacles, dense and prosperous road sections, road sections with large slopes, and pothole road sections.

The three-gear transition gear is mainly used for low-speed driving on urban roads, depending on the situation, acceleration can be easily transitioned to the fourth gear, and deceleration can be easily reduced to the second gear.

The four-speed driving gear is mainly used for long-term high-speed driving, economic driving, and the most economical speed of most vehicles will appear in the low-speed section of the fourth gear.

Five-speed gear, mainly used for long-distance driving on highways.

I don't know. The ghosts don't know.

No, you don't.

Relax the accelerator pedal when downshifting, quickly step on the clutch pedal, move the gear lever into neutral gear, then relax the clutch pedal, quickly step on the accelerator pedal with your right foot (add "empty oil"), and then quickly step on the clutch pedal, move the gear lever into a lower gear, and relax the clutch pedal according to the essentials of fast-stop-slow, so that the car continues to drive in the new gear.

Downshift timing. During driving, when you feel that the engine power is insufficient, and the speed gradually decreases, it means that the original gear can no longer maintain the normal driving of the car, and you should change to the lower gear in time and quickly. If the speed of the vehicle is significantly reduced, it can be overstepped.

Slow release of the clutch and tap the throttle at the same time When downshifting, be sure to reduce the speed to the right speed for your gear. If you are new to the oil clutch fit, you need to find the right feeling for yourself and familiarize yourself with the clutch height of your vehicle.

If you feel a bit of a shift and want to reduce from 4th to 3rd gear, it stands to reason that the engine speed will drop when you step on the clutch, but the speed is still very fast, so you can change gears at this time.

Novices are not good at holding this measure, I usually wait for the speed to slow down, and then hang up the fourth gear.

As follows:

When the car is driving in high gear, the engine speed is relatively low (for example, the engine speed is 1000 rpm when the car is driving in 50 yards in 5th gear, and the engine speed is pulled up to 1100 rpm when driving in 4th gear).

In 5th gear, it needs to be lowered to 4th gear, and after taking off the gear, quickly release the clutch to make up for the empty oil, quickly step on the clutch and hang into the 4th gear (the purpose of the empty oil is to increase the speed of the engine, so that the speed of the gear that needs to be lowered to a low gear is proportional to the speed of the driving wheel to drive the speed of the transmission output shaft gear, so that it can be easily hooked, otherwise it will cause the phenomenon of tooth collision.

If there is no synchronizer tooth of the transmission, it is difficult to hang in without empty oil), lift the clutch and press the accelerator at the same time to prevent frustration, and do not touch the teeth when the vehicle downshifts, and the vehicle runs smoothly and forcefully after downshifting.

The car shift is divided into downshift and upshift, the upshift is from the low gear to the high-end does not need to add air, but to clutch the two feet, use the engine idle speed to reduce the speed of the transmission input part, and the need to hit a foot of empty oil is the downshift.

Downshifting means changing a gear with a larger gear ratio, that is to say, the speed of the vehicle is unchanged, the speed of the input end of the transmission is higher, and the speed of the input end (clutch driven disc) when the front side of the neutral gear is run according to the high grade of the front, which is obviously different from the speed demand of the gear to be shifted in the rear, so the two elements to be engaged have a large speed difference, which will produce a large collision sound.

Even can not change into the gear, according to the speed of the rear gear, the front input terminal needs to speed up the two to synchronize, therefore, to loosen the clutch, blast the oil, the front input speed to match the low gear, then to engage the original close to synchronization, it is easy to shift.

In fact, to understand this reason, to understand the transmission structure, to know which two parts to be engaged, and to calculate the speed difference between the two elements, so that you can thoroughly understand that the gear needs to be slowed down to the front, just the opposite.

1. Boot and bury step: the car is generally started in neutral gear when starting, step on the clutch to hang a gear after starting, and then slowly loosen the clutch, and when the front of the car has a slight shaking, the appropriate gas pedal, and then slowly loosen the clutch, and the vehicle will drive. It should be noted that the clutch should not be released too quickly, and the throttle should not be increased too quickly.

2. Gear: When driving, when feeling the throttle is big in a gear (mainly listening to the sound and looking at the tachometer) and the speed is not fast, it is necessary to hang a higher gear. When increasing the gear, release the throttle first, then take off the gear and enter a new gear after stepping on the clutch, then loosen the clutch by half, release the clutch while refueling, and so on.

It should be noted that the faster the speed, the faster the clutch is loosened, the faster the Tan grip is appropriate; The slower the speed, the slower the clutch must be, otherwise the vehicle will shake or pause.

3. Downshift: When driving, you should downshift when you feel that the current gear is not suitable for the speed of the vehicle (the obvious feeling is that the vehicle has a sense of shaking, and the throttle feels very tired), and the downshift is carried out in the reverse order of the upshift, and other operations are the same as the essentials of the upshift. (Of course, downshifts sometimes have to be based on road conditions, pedestrians and vehicle conditions, and after braking and slowing down, you need to let Qing downshift, and downshifts when you want to downshift).

Some students who have just learned to drive do not know how to operate downshift fuel replenishment, and do you need to clutch the accelerator at the same time to downshift fuel replenishment?

The owner needs to release the clutch of the car, gently step on the accelerator, or when the clutch is in a semi-linkage state, gently press the accelerator. Generally, the brother god is to loosen the clutch with the left foot, step on the accelerator with the right foot, and the two feet should cooperate at the same time, not at the same time, not only to be familiar with the clearance of the vehicle clutch, but also not to step on the accelerator too hard, otherwise it will hurt the clutch plate and waste gasoline.

The operation of downshifting and refueling will increase the comfort of the vehicle ride and driving, and can also increase the safety of driving. If the owner does not choose to replenish the oil when downshifting, the speed of the vehicle will change instantaneously when shifting, which will affect the service life of the car gearbox, so in order to avoid damaging the vehicle's gearbox, step on the accelerator and brake at the same time when downshifting. In the same way, the car also needs to be refueled when upshifting, and the operation and downshift are the same.

1. Step on the brakes first.

2. After the speed is reduced, step on the clutch again.

3. The most critical point is that although the stepping off ruler is after stepping on the brakes in the noisy time, it must be stepped on to the end before the brake (that is, disconnected first), so as to ensure the braking distance and ensure that the ignition will not be turned off.

The clutch and throttle work well to make the engine power transmission smooth and smooth, which is convenient for the car to start smoothly, and can also save fuel and extend the life of the clutch.

Improper coordination between the clutch and the throttle often causes stalling or body shaking when starting. In addition, when driving and changing gears, it is easy to cause the clutch pedal to loosen too quickly, which not only destroys the car, but also feels very uncomfortable to drive.

At the starting stage, put the gear position in neutral, press the clutch pedal after starting the engine, hang the gear lever into first gear, quickly lift the clutch pedal until the engine sound becomes low (at this time, the pressure plate and the follower disc begin to rub), and immediately slow down the speed of releasing the clutch to lift the sleepy pedal. Feel the shaking and moving tendency of the body in the process of slowly lifting the clutch pedal, when the car has a slight shake (the clutch is in semi-linkage) and there is a tendency to move, pause the clutch pedal slightly, and at the same time quickly refuel a little to cooperate, so as not to turn off the engine.
