How to choose the timing and gear selection of the car?

1: Shift before turning: This kind of gear reduction method is relatively simple and easy to master.

When the car approaches the road, collect the oil and slow down, reduce the gear from high speed to low speed or medium speed, pay attention to the downshift from the intersection not too early, not too late, the correct shift before the bend, should be done after the shift, it is necessary to move the direction to turn the wheel, so as to meet the requirements of the shift before the bend.

2: Shift in the corner: This shift method is a difficult action in driving, and the time is short and the difficulty is high.

This method is mainly used to control the speed of the vehicle in advance and turn with the engine when the vehicle is wide, the turning angle is flat, and the engine is used to control the speed of the vehicle to turn in advance. In the process of turning, the use of brake control speed can also be to control the speed of the vehicle in a certain range, in the two-handed large cross wheel to the left wheel, the friend hand hits a certain position to take advantage of the left hand wheel opportunity, quickly free the right hand, timely shift, and finally both hands alternately return to the wheel, complete the shift action in the turn.

3: Shift after turning: Mainly drive in the case of good road conditions, wide road surface, large turning angle, and not affected by road traffic, such as large roundabouts at large intersections.

You can not change gears in the bend, use the method of light throttle, make the vehicle maintain a certain speed to drive, turn, after the car completes the last turn, due to resistance or other influences, the original speed has not been adapted to normal driving, should be shifted in time after the turn, and accelerate driving.

The timing and gear of the car are two conditions, one is the speed of the corresponding gear, and the other is that the engine speed can be changed when it reaches 2000 to 2500 rpm.

Try to choose the shift time between 2500-3000 rpm, so that you can get better economy under the premise of ensuring power. To put an end to low-gear high-speed, when driving a car with a manual transmission, it should be changed to a high gear in time after the speed stabilizes; When driving a car with an automatic transmission, you should try to avoid using the "Sport" mode. In addition, manual transmission users should avoid starting in high gear.

Shift gears at the right time according to the speed of the car. Under normal circumstances, slow Ling Sakura, start to hang a gear, when driving a few meters with Wang accompaniment, then change to the second gear; When the speed reaches more than 20 miles, 35 miles and then shift to three gears; The speed reaches more than 35 miles, and 45 miles is changed to four gears; The speed reaches 45 miles or more, and changes to five gears.

The above is an ordinary five-speed transmission car, for a car with more than 6 gears, a gear can be added for every 15 miles of speed increase. In addition, when changing gears, you should be optimistic about the speed of the engine, and it is best to change gears in time when it is about 2500 rpm.

Sometimes when driving the car, you find that the vehicle is a little shaking, which means that the engine is running at low speed and high load, and you should immediately lower one or two gears according to the actual situation;

At the same time of shifting gears, the clutch and throttle should be well coordinated, and the clutch clutch should be stepped on low and then release the accelerator pedal, and then quickly shift to the corresponding gear. After shifting gears, let go of your hand immediately, and do not put it on the gear lever (commonly known as the gear target) for a long time, otherwise it is easy to damage the gear lever.

(1) Shift operation rules.

timely, accurate, decisive and prompt, do not procrastinate; Accelerate first and then upshift, decelerate first and then downshift.

2) How to increase the gear.

Step 1: Slightly increase the throttle. Turn the throttle to open the throttle wider before shifting gears (gearing), and add a certain amount of oil to make the engine have enough power to ensure that the speed of the vehicle does not decrease during the shifting process.

Step 3: Quickly grip the clutch grip. Almost as soon as you close the throttle, hold the clutch grip with the 4 fingers of your left hand (your thumb is still on the steering handlebar) and disengage the clutch as quickly as possible to get ready for shifting.

Step 4: Press the foot shift pedal. As soon as you hold the clutch grip with your left hand, step on the rear tread lever with the ball of your left foot or heel to shift into high gear. The power of the pedal should be just right, the action should be clean and neat, and the mud and water should not be dragged and the water should not be pedaled continuously.

Step 5: Relax the clutch grip evenly. After stepping on the shifting rear pedal lever with the left heel, the left hand immediately releases the clutch grip and engages the disengaged clutch in time and smoothly, so that the engine power is quickly transmitted to the rear transmission, ready to increase the speed of the vehicle.

Step 6: Increase the throttle. When the left hand releases the clutch grip, the right hand turns the throttle knob downward in time to the rear, so that the closed throttle opens, the opening should be moderate, not too large or too strong.

3) How to operate the downshift.

Step 1: Hold the clutch grip tightly while closing the small throttle.

Step 2: Step on the foot shift tread lever front tread. Press the front pedal lever with your left toe to shift the transmission from a high-speed to a low-speed shift.

Step 3: Increase the throttle and relax the clutch grip.

4) Precautions when changing gears.

When changing gears, it is necessary to grasp the timing of shifting gears according to the speed relationship between different gears. If the vehicle shuddes when changing into a higher gear, or even has to turn off, then you should hold the clutch grip tightly, lower the gear, and then switch to the next gear again after the speed increases. If the vehicle shifts into low gear, it feels like it is dragging backwards, which is mainly caused by the high speed and low gear and the downshift without slowing down, which not only consumes fuel but also easily damages the parts.

With the right speed and gear, there will be no rushes and stalls.

The shift of the motorcycle should be carried out in order, and a certain gear should not be skipped. Do not press the transmission pedal too hard (pull the gear lever) too hard, and do not kick hard with your foot.

When shifting gears, keep your eyes straight ahead at all times, and don't look down, look left or right, or be distracted.

The maximum driving speed of each gear should be controlled within the specified speed, see Table 2-1. Most motorcycles use the driving force when the air cooling gear is large and the speed is slow, so the engine temperature rises faster, and the fuel consumption is more, and if the engine is damaged more if the first gear is used for a long time. Therefore, the time of use should not be too long.

Table 2-1 Relationship between motorcycle travel speed and gear position.

The correct shift operation should do the following:

1. The clutch should be stepped on the bottom to change gears. 2. When changing gears, increase and downshift according to the current speed.

3. Lift the clutch after changing to the required gear, do not lift the clutch before the gear is in place.

In addition, it should be noted that when shifting gears while driving, the operating clutch pedal should be quickly pressed and lifted, and no semi-linkage phenomenon should occur, otherwise, the wear of the clutch will be accelerated.

The relationship between the gear and speed of the car:

For the convenience of memorization, the equal difference series was selected as an approximate reference: 1st gear. 10-40km 2 gears.

15-80km 3 gears. 20-120km 4 gears. 25-160km 5 gears.

30-200km such as Fit: Description writes the maximum speed of 165km, the actual look at 2800 rpm 90km, the maximum 6000 rpm can reach 193km, 5 gear idle 800 rpm speed 193 * 800 6000 = 26km. The gear ratio of the 1-5 gears of the Fit gearbox is, that is, the 5th gear is a multiple of the 1st gear, the maximum speed of the 1st gear is 193, and the speed of the 1st gear idle 800 rpm = 26.

When to shift gears:

1. Novices need to observe the tachometer and speedometer to shift gears; Veteran players mainly rely on the feeling of shifting gears (such as sound, etc.), and the feeling is formed after a long period of accumulation.

2. Generally speaking, shifting gears according to the speedometer is more practical for novices. 1 gear for 10 km/h, 2 gears for 20 km/h, 3 gears for 30 km/h, 4 gears for 40 km/h, 5 gears per hour for 50 km/h and above.

3. If you change gears according to the speed, generally speaking, 2000-2500 shifts the gears, and drives at 2000 shifts to a healthy speed.

4. Note: The principle of gear shift is: speed determines gear.

to what speed to scrape what gear. Remember: accelerate first when upshifting, and slow down first when downshifting.

For example, if you are in 5th gear, you apply the brakes when turning, and the car slows down, and the gear should be reduced accordingly according to the speed. Downshifts do not have to be downshifted, but can be reasonably selected according to the situation and vehicle speed.

5. The accurate shift time is when the speed of the vehicle is not increased much but the engine speed increases sharply, and the actual driving process can be judged by the engine sound or engine tachometer: when the throttle is not very big but the engine roar is obvious, it should be changed, or when the tachometer exceeds 1000 rpm, you can consider shifting. (The above judgments refer to the normal starting state, high-speed operation and half-slope start are not counted).

6. Theoretically, each clutch should be lifted slowly, although the direct and fast release of the clutch does not affect the driving on the surface, but will cause some damage to the gearbox and engine, it is recommended to slowly raise to the half clutch and then lift it after about half a second.

If you want to know when it's time to change gears, you should first understand what "drag gear" is, and if you feel like you're about to drag a gear, you need to change gears.

Normal 2000-2500 conversion gear high engine shift speed can be higher.

I asked someone and some people said that around 15km add 2 gears, 25km to 3rd gear, the same 35km 4th gear, 45km with 5 gears, is this correct? The safety routine (except for the racers) is basically correct, because your coaches are mostly low-revving and high-torque engines (ordinary Santana. Jetta, etc.) But if you encounter a high ** motivation, then you have to turn 2500 to 3000 to change gears (standard 206, 307, etc.) and when you add gear, step on the clutch when you shift 1 to 2 and then shift the clutch to refuel, and put it slowly, because at that time the engine load is fast and there is a sense of vibration, and the right foot of the downshift does not need to touch the accelerator at all, and the right foot should be placed on the brake pedal!

Brothers, learn slowly!

Six words: slow acceleration, fast shifting.

It's when there is enough power in the previous gear, or when the front can run fast.
